New Solutions to Old challenges: Key Symposium on Nanomedicine Against Cancer

Symposium on nanomedicine vs cancer: experts gather Nov 28 in Málaga to tackle tumor-targeting challenges and advance innovative therapies.

Málaga, november 2024. On November 28th at 9:00 AM, the Salón de Actos at IBIMA (C/Severo Ochoa, 35, Málaga) will host the symposium “Targeting in Nanomedicine Against Cancer,” bringing together leading experts to discuss the critical challenges and advances in applying nanomedicine to oncology. Organized by IBIMA, this event will shed light on one of the most pressing issues in cancer nanomedicine: the difficulty of delivering nanostructures to tumor cells.

The challenges to overcome cancer

Cancer remains one of the world’s most significant health challenges, with nearly 20 million new cases annually and 9.7 million deaths in 2022. Despite notable advances in treatments—ranging from surgery and radiotherapy to immunotherapy and metabolic therapies—many patients continue to face poor outcomes. Nanomedicine has generated substantial excitement over the last three decades, particularly since the approval of Doxil™, the first nanomedicine for cancer. However, challenges persist.

Latest breakthroughs in pulmonary drug delivery and cancer research at NANBIOSIS

On World Pharmacists’ Day, NANBIOSIS Units highlighted for breakthroughs in pulmonary drug delivery and cancer research, advancing treatments for respiratory diseases and brain cancer.

Barcelona and Zaragoza, September 2024. On World Pharmacists Day, we celebrate the vital contributions pharmacists make, not only in patient care but also in groundbreaking research that is shaping the future of healthcare. This year 2024, we want to give this significant date a little twist: by showcasing a few examples of how our Units are contributing to healthcare and new pharmaceutical approaches. Two key NANBIOSIS units —Unit 9 and Unit 25— are at the forefront of said scientific advancements, offering promising solutions for respiratory diseases and cancer treatments.

Innovative pulmonary drug delivery

One of the most appealing means to treat respiratory diseases is the delivery directly into the lungs by the use of aerosols containing the drug. This allows having a highly concentrated drug dose in the affected tissue, without exposing the rest of the body to it. However, when done as a dry aerosol powder, this strategy suffers an important drawback: the difficult dispersion of solid particles whose sizes are in the micron or even nanometric scale, which tend to form clusters and larger structures and thus hindering the delivery. And this is where Unit 9 comes to play.

In collaboration with the University of Zaragoza (UNIZAR), our researchers M. Pilar Lobera, Jesús Santamaría and their coworkers, have made remarkable strides in improving this type of pulmonary drug delivery. They have developed an advanced aerosol generator that addresses key limitations in traditional inhalers, including inconsistent dosing and poor control of particle size.

“All nanoparticles used in the validation of this method of aerosolization were synthesized by Unit 9, using coprecipitation, microfluidics or electro-spraying methods.”

M. Pilar Lobera

This aerosol generator delivers highly dispersed particles directly to the alveoli, the deepest part of the lungs where drug absorption is most effective. The technology offers several crucial benefits:

  • Precise particle control for targeted lung delivery, free of aggregates.
  • Improved bioavailability, ensuring more effective treatment targeting the alveoli and other targeted regions within the lungs.
  • Reproducible dosing across different patients, regardless of how damaged is their lung function.

These advances have the potential to revolutionize the treatment of respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, and lung cancer. Capable of aerosolizing a wide range of particles containing diverse biomolecules, including proteins and peptides, the device also shows promise for inhaled vaccines.

A) SEM images of original dry powder formulation. B) SEM image of captured drug in aerosol phase C) TEM image of captured drug in aerosol phase C) Particle size distribution in the aerosol obtained was analyzed in real time using a Scanning Mobility Particle Spectrometers with Condensation Particle Counter as detector, SMPS+C: Foster NextHaler: GMD = 44 ± 1.7 nm; ~ 2400 #/cm3; Ultibro Breezhaler ®: GMD = 70 ± 5.4 nm; ~ 8700 #/cm3

In testing, the device achieved a fourfold increase in alveolar deposition compared to current inhalers, with 99% of particles sized optimally for deep lung delivery, all the way into the alveoli. This breakthrough marks a significant step forward in making inhaled therapies more effective and accessible for patients.

Advancing cancer research

Meanwhile, at NANBIOSIS Unit 25, located at Universitat Autònoma de Barcelona (UAB), researchers are pushing the boundaries of cancer treatment through cutting-edge imaging technologies. Ana Paula Candiota explains to us how their Bruker 7T MRI/MRS/MRSI preclinical scanner allows scientists to noninvasively monitor cancer progression in live animal models. This is particularly interesting in orthotopic models, where tumors grow in their natural location. This technology is crucial for accurately assessing the efficacy of new cancer drugs over time, offering an advantage over traditional subcutaneous models.

One of the standout projects at Unit 25 involved testing a novel treatment for glioblastoma, one of the most aggressive forms of brain cancer. Researchers used intranasally administered Catechol-Based Pt(IV) Coordination Polymer Nanoparticles encapsulating cisplatin. This innovative approach reduced the drug’s toxicity while maintaining its effectiveness, showing great promise for noninvasive cancer therapies.

“The encapsulation aimed to reduce cisplatin’s toxicity, and the study yielded promising results.”

— Ana Paula Candiota

The work being done at Unit 25 highlights the importance of advanced technology and collaboration in the fight against cancer. By enabling more precise evaluation of drug effectiveness and reducing harmful side effects, these innovations bring us closer to more targeted, patient-friendly treatments.

Celebrating Pharmacists’ impact on research and healthcare

The groundbreaking research taking place at NANBIOSIS Units 9 and 25 reminds us of the essential role pharmacists play, not only in providing care but also in driving medical innovation. Whether that means improving drug delivery systems for respiratory diseases or developing noninvasive cancer treatments, their work is shaping a healthier future for all.

New cathalitic therapy for destroying key molecules within tumor cells

The prestigious journal Nano Letters published the work led by NANBIOSIS researchers, affiliated with Unizar, INMA (CSIC-UNIZAR), CIBER–BBN, and IIS Aragón.

The successful development of this innovative treatment approach was possible through the efforts of our Unit 9, led by Prof. Santamaría and Dr. Hueso, both corresponding authors of the publication.

As recently announced by Universidad de Zaragoza (Unizar), a team led by NANBIOSIS researchers at the Instituto de Nanociencia y Materiales de Aragón (INMA, a joint institute of CSIC and UNIZAR) has discovered a way to artificially conduct a new chemical reaction, called transamination. This approach can act within cancer cells to destroy molecules vital for the development and growth of tumor cells. The prestigious journal Nano Letters have recently published this work, led by Unizar professors and researchers Javier Bonet–Aletá, José Luis Hueso, and Jesús Santamaría, also affiliated with NANBIOSIS, INMA (CSIC-UNIZAR), CIBER–BBN, and IIS Aragon.

The technique aims to replace current chemotherapy, carrying catalysts that either generate toxic molecules inside the tumor or eliminate molecules it needs to keep growing.

Catalytic therapy constitutes a new strategy in the fight against cancer, aiming to trigger harmful chemical reactions for the tumor. Ultimately, the goal is to replace current chemotherapy by carrying catalysts that either generate toxic molecules inside the tumor or eliminate molecules necessary for its proliferation.

Regarding eliminating key molecules, first published in 2015, catalysts targeted either glucose, an important energy source for cancer cells; or glutathione, an antioxidant that protects tumor cells from highly reactive radical species. The later is partly responsible for these cells’ resistance to chemotherapy treatments. Both glucose and glutathione can be eliminated through oxidation reactions. However, this is especially challenging to apply due to the scarcity of oxygen in the hypoxic tumor environment.

The publication:

This study holds special importance not only because it opens the field to new reactions of interest in oncology, but also because it does so in a process – transamination – that does not require oxygen to occur. This eliminates the main restriction of catalytic therapies. The reaction operates on amino acids, essential components that cells use to produce proteins, and also pyruvate, a small and abundant molecule involved in the main energy acquisition pathway in the cell. The reaction between them reduces the levels of amino acids and pyruvate in cancer cells, leading them to a critical state and halting their expansion and growth.

Graphical abstract of the publication. Read the full article in: Nano Lett. 2024, XXXX, XXX, XXX-XXX

During transamination, an amino group is exchanged between an amino acid and pyruvate, generating a substance that the cell cannot easily utilize. Our researchers demonstrated this by reacting pyruvate with various amino acids, such as glutamine, aspartic acid, glutamic acid, or glutathione itself. However, transamination has one drawback: it is catalyzed by copper atoms, whose flow through the cell membrane under normal conditions is highly restricted. To overcome this limitation, researchers designed nanoparticles containing this metal, enhancing internalization into tumor cells. Once internalized, the nanoparticle dissolves, releasing copper atoms that act as catalysts in the transamination reaction.

In addition of Dr. José Luis Hueso, and Dr. Jesús Santamaría, other members of Unizar also participated, such as Dr. Javier Martin–Martin from the Department of Organic Chemistry and INMA, and Dr. Miguel Encinas–Giménez, Dr. Ana Martín–Pardillos, and Dr. Pilar Martín–Duque, who are also members of the Aragon Health Research Institute (IIS), as well as Dr. Juan Vicente Alegre Requena, a CSIC scientist at the Institute of Chemical Synthesis and Homogeneous Catalysis, ISQCH, a joint CSIC-UNIZAR institute.

Women in NANBIOSIS part 4: María Sancho’s journey from nanomaterials to cancer therapy

Our expert in nanocarriers talks about her journey from biotechnology to cancer therapy, an example of passion and perseverance in science.

February 2024, I3A/CIBER-BBN, Zaragoza (Spain)

The silence of the meeting room is only broken by the constant purring of the heating system. A large square table made of dark wood fills the entire room almost completely. Its dimensions are too extensive for anyone to reach its center. One may wonder, how many passionate conversations about the next step to take in countless research projects have been witnessed by these four walls?

The door swings open briskly, and a familiar face crosses the threshold with a smile. We have shared lab bench in the past, and María, with her memory honed by years of dedication to her craft, remembers that brief period of our lives surprisingly well. We greet each other warmly. She radiates energy and passion for what she does.

The interview begins.

Hello María, tell us a little about yourself.

“My name is María Sancho, I studied a Bachelor’s Degree in Biotechnology at the University of Zaragoza, just the second generation after its implementation. I did my bachelor’s thesis at the Institute of Nanoscience and Materials of Aragon (INMA), and this contact with nanotechnology made me decide to continue expanding my training in this field and try to dedicate myself to science and research. Then I did the Master’s in Nanomaterials, the ‘NanoMat’, at INMA, as it complemented my biochemistry-oriented training very well with the materials aspect of the Master’s.

After I finished both my bachelor’s and master’s thesis at INMA, I had the opportunity to apply for (and obtain) a prestigious State doctoral scholarship with Jesús Santamaría as Principal Investigator. This allowed me to do my thesis here in Zaragoza, which I defended in December 2020. For the past three years, I have been in Milan, at the Mario Negri Institute of Pharmacological Research, with Luisa De Cola. Her outstanding work focuses mainly on nanomaterials, different from those I worked on during my thesis, allowing me to train in a highly complementary area.”

So, you’re currently doing your postdoc in… Italy?

“No, no. I just returned last October, once again, to Jesús Santamaría’s group, with the goal of establishing here in Zaragoza as a researcher… if possible (laughs).”

“I am fortunate to be able to devote myself to something I am passionate about. Research is something I enjoy every day.”

—Dr. María Sancho, Researcher at Unit 9.

What motivated you to choose a career as a researcher?

“Ever since I was very young, I’ve been an inquisitive, curious, and creative person. I got into research spontaneously, although it’s true that in my family we always talked about scientific research, my father was a teacher and a geologist himself. Over time I’ve realized that science has a vocational component, it requires a lot of dedication, but it excites me. During my high school studies, I was clear about choosing the scientific path. After finishing high school, I pursued a degree in Biotechnology, which had been implemented in Zaragoza just a year before. During my studies, I witnessed the significant advances of the great nanotechnological revolution of recent years. My interest grew only stronger and I decided to do my doctoral studies.

In 2016, I obtained a prestigious and competitive contract for the so-called University Professor Training State program ‘FPU’ from the Ministry of Education. This allowed me to carry out my doctoral thesis at the University of Zaragoza, in a leading and excellent research institute like INMA. So, I could say that I didn’t hesitate to start my career as a scientist. During this period, I was fortunate to have thesis supervisors who transmitted their passion and enthusiasm for research to me. This undoubtedly encouraged me to continue developing my scientific career. Today, I can say that I am fortunate to be able to devote myself to something I am passionate about. Research is something I enjoy every day.

Could you share with us a bit about your area of research and the projects you are currently working on?

“In general terms, my research focuses on developing small containers, which we call nanoparticles, with nanometric dimensions. This means that they are much smaller than human cells. Specifically, my project is based on developing nano-containers capable of directing and transporting drugs and anti-tumor molecules in the body. This way, we load these nanoparticles, which have therapeutic properties, inside vesicles produced by our own body, so that they can kill and act against tumor cells. We hope that these nano-containers with therapeutic properties, once injected into the bloodstream, can reach their target cell and then release the drugs loaded inside them. When we take a painkiller for example, only a small part of the drug acts to relieve that headache. In this project, what we aim for is the possibility of using less therapy and directing it selectively to the tumor. In this way, the maximum possible amount of the supplied active compound reaches the cancer cells. Furthermore, by being encapsulated in these nano-containers and selectively reaching tumor cells, it would ensure avoiding side effects and not affecting other organs.”

What have been the greatest challenges you have faced as a woman in your research field?

“From my experience, to this day, I have not faced challenges attributed to gender. I believe the greatest challenges I have encountered have been common to those of my male colleagues, and are linked to being ‘young researchers’. I associate these challenges with the fact that research is not only an occupation of nearly irrelevant importance in Spain, but also one of great uncertainty, and it is not sufficiently recognized. It requires great dedication, many hours of work, sometimes yielding good results, and other times not. Furthermore, there are few and highly competitive State grants in Spain that allow you to dedicate oneself to research continuously and steadily. As you progress in your research career, you spend more time on bureaucracy, seeking funding and more projects. And the truth is that in the vast majority of cases you won’t get them. This derives in less hours in the lab doing the experiments. I believe there are not enough resources available today.”

Have you ever experienced any type of gender bias or added difficulty in your scientific career? How have you addressed this situation?

“From my experience, up to this day, I have not encountered any additional difficulties compared to men. Nor have I experienced any situations of inequality. However, I do believe that all young researchers, in general, both women and men, face significant challenges in advancing and developing their professional careers. In fact, many of the colleagues I encountered while doing my doctoral thesis have been forced to abandon their scientific careers.”

Could you tell us more about your challenges as a young researcher?

“One of the biggest challenges has been having to go abroad to continue my scientific career. This requires great effort and dedication. Already during my doctoral thesis, I undertook two stays abroad. One of them was for three months at ETH Zurich. The other one lasted for two months at Politecnico di Milano. After completing my doctoral thesis in 2020, I followed the advice of my supervisor to go abroad for at least two more years to continue my postdoctoral career. It was not an easy decision, as I embarked on my journey amid the COVID pandemic, but I had the opportunity to get a job interview with Luisa De Cola, the leader of a globally renowned group.

Although it has been a path full of changes and uncertainty, I don’t feel like I have had to give up anything I wanted in order to pursue my work. However, it’s true that research has taken my time away from other activities. I have probably missed out on doing some things. I have spent two and a half years away from my family and friends in order to continue my education. All this with the goal of returning to Spain as a researcher, which wasn’t even guaranteed. In my case, a few months ago, I managed to secure a postdoctoral grant to develop a research project for four years in Zaragoza, so it has been worth it. Specifically, I have returned to INMA to join the group led by Jesús Santamaría (who was also my thesis supervisor), one of the top scientists in Aragon. He has been involved and supported me throughout my journey as a researcher, even while I was abroad, and he advocated for my return to INMA.”

What advice would you give to young women who are considering pursuing a career in science?

“Firstly, if you’re considering it, I believe that research, like other professions or activities, often reveals its fascination only once you experience it from within. Additionally, it’s a profession that greatly nurtures the mind, fills you with stimuli… and it’s very enriching to formulate a hypothesis and be able to test it in the laboratory. I think it’s something rewarding not only professionally but also personally. In addition, it is a profession that allows you to travel to other countries, get to know other cultures, people who started as colleagues and then became friends. On the other hand, all the teamwork it requires is very satisfying. The individual work you do in the laboratory is later contrasted with others. And yes, it is true that there are bad days when things don’t go your way, but when something works out, it more than makes up for it.”

This is great timing for my next question. Have you had any ‘Eureka’ moments? What do you consider your greatest achievement, or something you feel particularly proud of?

“In 2019, there was a moment when there was a cocktail of people who were working exceptionally well and enthusiastically, of the results we were obtaining, and of the project… All of this allowed us to publish my first paper in Nature, which was highly cited afterwards. This was a really cool moment for me.”

Your very own first-author scientific publication… in Nature. And you were still doing your thesis!

“Yes, I was still working on my thesis. But of course, this achievement is not mine alone. It’s very much intertwined with all the teamwork behind it. It’s a publication that goes hand in hand with projects that Jesús Santamaría had at that time, which allowed us to test all the ideas we had. And of course, thanks to the work of many people, like Santamaría himself, Víctor Sebastián, Pilar Martín, and international collaborators we had in Edinburgh… In short, it was a cocktail that allowed us to do something that didn’t exist in the field. No one had tried vesicles with this type of nanoparticles to make catalysts before! It was a group effort, and very satisfying for all of us.”

If someone in your family, who is not a researcher, asked you about your publication in Nature, how would you explain it to them?

“Well, from a scientific point of view, we managed, for the first time, to encapsulate palladium nanosheets in lung cancer exosomes. These nanosheets are harmless to our body, but they can catalyze a reaction that halts the growth of cancer cells.”

And, as you well said, it was a group effort. What was your contribution to that publication?

“What I did was isolate the vesicles and develop a system to produce the nanosheets inside the vesicles without altering their properties. The thing is, up until that point, when attempts were made to attach these nanosheets to the vesicles, the vesicles ceased to be selective to the cancer they were targeted to. This was because the methods used were too aggressive, causing significant damage to the vesicles. What we did was to develop a very gentle method to achieve high encapsulation efficiency and maintain their ability to selectively reach the tumor. On the other hand, our collaborators in Edinburgh studied all the catalysis and reaction dynamics. So, when we administer a systemic prodrug, it’s harmless throughout the body. But as soon as it reaches the tissue where the cancer is located, this prodrug is catalyzed by the nanosheets into its toxic derivative, acting only on the tumor cells.”

That’s brilliant. Plus, you won’t have the biocompatibility issues seen in other drugs.

“Exactly, because the exosomes you use are naturally produced by the cells themselves. That’s the difference compared to other forms of encapsulation. We only tested it at the in vitro level with cells. But imagine being able to use the patient’s own exosomes to encapsulate the nanosheets. This is a starting point to explore this novel therapy further.”

And indeed, it ended up being published in Nature.

(laughs) “Yes, when such a crazy and bold idea gives you such a good result, it kind of gives you the motivation you need to keep going. And that curiosity we were talking about earlier, which I believe every scientist has, produces a very satisfying and inspiring feeling.”

What changes would you like to see in the scientific world to promote gender equality?

“I believe that calls and projects are being adapted more and more to consider maternity leave periods, etc. This allows individuals of all genders to compete on equal terms. However, it’s true that in higher-level positions, certain roles are still more commonly occupied by men. Although, it’s also true that there are more and more female principal investigators (PIs) leading research groups. I think in the future, we’ll see more and more women leading research groups as PIs.”

How do you think we can encourage more women and girls to participate in science?

“There are many science outreach activities highlighting the role of women in science or showcasing prominent female scientists. Activities like this one, promoted by CIBER-BBN, or by other institutions, are important. In my own Institute (INMA), numerous such activities are conducted, which are part of the objectives included in its Strategic Plan. From the scientific community, we are very interested in promoting interest in science, communicating the importance of scientific advances in different research areas, and conveying the daily work carried out at a prestigious research center. At my institute, we strive to make women and girls visible, inspire them, and promote their participation in science. This includes talks, exhibitions, roundtable discussions, competitions, scavenger hunts, activities in pubs, and a series of scientific talks aimed at schools, as well as in-person workshops.

I don’t think we’re doing it wrong. What is more, I think since COVID people have become more aware of the importance of scientific development. A few years ago, few people knew what a PCR was or the effort behind vaccine development. I believe it is important that society as a whole understands what these careers entail.”

That’s all. Thank you very much, María. It’s been very interesting.

“I’m glad!” (laughs)

Women in NANBIOSIS part 2: Ana Martín, and her Multi-degree Journey

We ask Dr. Martín about her innovations in cancer treatment with nanoparticles, in the context of her collaborations with NANBIOSIS.

This is part of a series of interviews to several female researchers within the context of International Day of Women and Girls in Science 2024 and Woman’s Day 2024. For more interviews, visit our news section here.

February 2024, INMA-CSIC/CIBER-BBN, Zaragoza (Spain)

We are walking through the tall corridors that connect the numerous blocks of the large R&D Building, located near the Río Ebro Campus of Unizar. This building is a conglomerate of institutes, laboratories, and research groups. In its dead center, open to the outdoors, a Zen Garden welcomes us, like an oasis of peace in the midst of this whirlwind of information, advancements, and scientific progress.

We enter the meeting room. The lights are flooding a large dark table surrounded by chairs. After a few minutes, Ana arrives. We greet each other warmly. It has been a long time since we last saw each other, perhaps since college? With a nervous laugh, she confesses, “Having a microphone in front of you is quite intimidating…”. She laughs again.

I consider making a joke right after the first question, in an attempt to reassure her. But I quickly change my mind as soon as she starts talking. Her nerves have completely dissipated, and her words, once shaky, now fill the recording with a confidence I didn’t expect. The confidence of someone who carries behind them a career as varied as it is fascinating.

The interview begins.

Well, Ana, tell us a little about yourself.

“My name is Ana. I have a degree in Veterinary Medicine, a degree in Biochemistry, and a Ph.D. from the University of Zaragoza. Currently, I work in the NFP group. My chemist colleagues synthesize nanoparticles, and I use them for anti-cancer treatments.”

What motivated you to choose a career in science?

“Since I was little, I’ve always been very interested in natural sciences. I’ve always been intrigued by how biological systems work, and over time, I became interested in pathology, the cause of diseases, and their treatment. That’s why when I had to choose a career, I chose Veterinary Medicine and, later, Biochemistry.”

Could you share with us a bit about your research area and the projects you are currently working on?

“Since I started working in research, I have been involved in the field of biomedicine, but the areas have been progressively changing. My career began in the field of aging and vascular diseases. Later on, I applied this knowledge to cancer research, which is the field I am currently working in, using nanoparticles as an anti-tumor treatment.”

What nanoparticles do you use?

“We use nanoparticles that, through catalysis, consume glucose and produce toxic species, inducing cell death specifically in tumor cells. We have many types of nanoparticles, especially by combining different types of metals. We introduce them into extracellular vesicles, which have tropism towards tumors, significantly improving the treatment compared to free nanoparticles.”

And what types of cancer do you treat?

“We use different cell lines from lung cancer, colon cancer, cervical cancer, brain cancer… We aim to create a treatment that is not specific to one type of cancer but can be applicable to many types of tumors. And high glucose consumption is something that tumors have in common.”

What have been the greatest challenges you have faced as a woman in the field of research?

“I believe the most difficult challenge has been balancing a scientific career with personal life, specifically with motherhood. When you work as a scientific researcher, there is never a perfect time to have children. You know that your career will be put on hold for a while, and research never stops, so there is a constant fear of falling behind. But as a scientist and a mother, I think one should never give up on motherhood because of it. In the end, everything is achievable, and personal life should never be sacrificed for professional life.”

Have you experienced any gender bias or added difficulty in your scientific career? How have you addressed this situation?

“In my case, I have been fortunate and I don’t believe I have experienced any gender bias. However, I do know of cases involving female colleagues who have encountered it.”

“There are challenging moments during a scientific career (…), but in the end, persistence pays off.

—Dr. Ana Martín, collaborator scientist in Unit 9.

What advice would you give to young women considering pursuing a career in science?

“My advice would be to enjoy the work in research. We have to remember that it is one of the best jobs out there; we are doing something for society, to improve it, whether working in biomedicine or other areas like technology. There are challenging moments during a scientific career, times when it’s difficult (due to lack of funding, opportunities, etc.), but in the end, persistence pays off. And if for some reason it doesn’t work out, all the knowledge gained will still be very useful in other areas.”

And what advice would you give to those who are unsure?

“Well, if they’re not sure… before diving into a doctoral thesis, they should visit laboratories, see how things work here, and choose something they enjoy. Because you’re going to spend a lot of time working on it, and the environment you’re in is very important.”

How do you think gender stereotypes can be overcome in your research field?

“I don’t believe there are gender stereotypes. However, it is true that currently, positions of greater responsibility are often held by men. In my opinion, equal opportunities should be given to men and women, and the time taken by women for their careers due to motherhood should not be penalized. This way, we can finally break the ‘glass ceiling’, and young people can also have female role models.”

And what about being a mother?

“In other countries, I’ve seen people having children during their doctoral thesis, and that’s unthinkable here. I believe the measures taken so far are just a patch and don’t fully compensate.”

What do you consider your greatest achievement or contribution in your field of study?

“Personally, my greatest achievement was obtaining a project on breast cancer in which I was Principal Investigator. As for my greatest contribution, I couldn’t say for sure. I believe everything I have done has contributed a little bit to research on vascular calcification, aging, and cancer. Perhaps it may seem somewhat insignificant, but it could be very important in aiding future research.”

What support have you received throughout your career that has been particularly helpful?

“The support of my family and my partner has been indispensable throughout my career. I also appreciate the support of the Government of Aragon and the European Union for the funding I received during my predoctoral and postdoctoral stages.”

What changes would you like to see in the scientific world to promote gender equality?

“I would like to see women not have to postpone or give up their personal lives for their work. I believe that, with the support of institutions, anything is achievable, as is the case in other European countries.”

How do you think we can encourage more women and girls to participate in science?

“I truly believe that there are more women in science than men. The problem is that leadership positions are almost never held by women, perhaps because many women end up sacrificing their careers for their personal lives, and that shouldn’t happen. We should break the glass ceiling and allow women to access leadership positions so that girls have examples of female scientists to follow and don’t think that science is only for men.”

It’s been a pleasure to see you again and chat with you, Ana. And thank you for your time.

“Thanks to you too.”

Bringing Hope to Cancer Treatment: New Pioneering Advances in Nanotechnology

NANBIOSIS Researchers Lead the Way in Innovative Nanomedicine Approaches

Cancer remains a formidable challenge globally, with 19.1 million cases diagnosed in 2020, resulting in nearly 10 million deaths. However, amidst these alarming statistics, a beacon of hope emerges from the field of nanomedicine.

Spearheaded by Professor Jesus Santamaria and his team at the NFP group, part of the NANBIOSIS ICTS Unit 9, groundbreaking advancements in nanotechnology are revolutionizing cancer treatment. Funded by the European Research Council, their efforts mark a significant stride towards more effective and targeted therapies.

“The potential adverse effects (of antineoplastic agents) on healthy cells is the main limitation, in addition to the development of drug resistance by cancer cells.”

—Dr. Jose L. Hueso, Scientific Coordinator of Unit 9

Traditional cancer treatments like surgery, chemotherapy (CT), and radiotherapy (RT) have long been the mainstays of clinical intervention. While effective, their indiscriminate nature often leads to debilitating side effects and the development of dreaded drug resistances in cancer cells. Chemotherapy, in particular, poses significant challenges due to its adverse effects on healthy cells.

This is where nanoscience and nanotechnology come to play. These cutting-edge disciplines offer promising avenues for the development of selective and precise cancer therapies. The work of Prof. Santamaria’s team focuses on leveraging nanoparticles to deliver tailored treatments directly to cancerous tissues while minimizing collateral damage to healthy cells.

Their innovative approach involves the synthesis of inorganic and carbon-based nanoparticles with enzyme-mimicking capabilities. These nanoparticles exhibit a multifaceted response within the tumor microenvironment, from consuming glucose to generating reactive oxidative species. Moreover, they disrupt the antioxidant defense mechanisms of cancer cells, rendering them more susceptible to treatment.

Collaborative efforts with esteemed researchers like Pilar Martin Duque, Luisa de Cola, and Asier Unciti-Broceta further enhance the potential of these nanotherapeutic strategies. Together, they strive to refine nanoparticle delivery systems, protect the catalytic activity in the tumor microenvironment, and engineer anticancer prodrugs using bioorthogonal chemistry.

The implications of these advancements are profound. By harnessing the power of nanotechnology, researchers have the tools to revolutionize cancer treatments. With greater specificity and reduced toxicity, nanotherapies offer renewed hope for patients battling this relentless disease.

As the field of nanotechnology continues to evolve, the potential for personalized, precision medicine approaches tailored to individual patients becomes increasingly tangible. With the expertise of NANBIOSIS ICST researchers at the forefront of this revolution, the future of cancer treatment shines brighter than ever before.

NFP group: Members currently working on the development of novel strategies of synthesis, encapsulation and delivery of active catalysts against cancer include: Dr. Víctor Sebastián, Dr. Ana Martín, Dr. María Sancho, Dr. Jose L. Hueso, Dr. Javier Bonet and PhD students: Andrea Mosseri, Ángeles Valls, Miguel Encinas, Jose Ignacio Garcia Peiro, Leticia Sanchez, Estefanía Chico.
