The book “Nucleic Acids Chemistry” takes the most important aspects of the methodology of oligonucleotides synthesis, that is currently expanding by the endorsement of a dozen of new medicines, such as the first medicine based on interfering RNA for the control of LDL and cholesterol in blood that will facilitate the decrease of cardiovascular illnesses.

The writing of the book has been directed by Dr. Ramon Eritja, of Centro de Investigación en Red de Nanomedicina (CIBER-BBN) and is Research Professor at Institute of Advanced Chemistry of Catalonia (IQAC-CSIC), being its director between 2012-2017. The co-authors are Carme Fàbrega, Anna Aviñó, Santiago Grijalvo, Andreia F. Jorge, from IQAC-CSIC, Carlos González from Instituto de Química Física Rocasolano (IQFR-CSIC) and Raimundo Gargallo from University de Barcelona  The book began to be written in mid-2019, although most of the book was written during the lockdown.

In the last five years, an expansion of technologies based on DNA and RNA in diagnosis and therapeutic use has been produced, and it has been very important in the research of quick solutions to avoid the COVID pandemic and, predictably, the research group’s environment has led the development of several solutions, like biosensors for the direct detection of SARS-CoV-2.

A former PhD student of Ramon Eritja group, Dr. Ramón Güimil García, Head of Synthetic Oligonucleotides bei BioNTech, has participated in the development of the BioNTech-Pfizer mRNA vaccine. Another doctor, Brendan Manning, formed member of the group, has participated in the development of a diagnosis kit named Sherlock, which uses the CRISPR-Caspasa system for the detection of the virus that causes COVID.

Dr Erija completed his doctoral thesis at the University of Barcelona directed by Dr. Ernest Giralt on the subject of peptide synthesis. In 1984 he carried out his first postdoc with Dr. Itakura at the Beckman Research Institute of City of Hope in Los Angeles where the production of the first synthetic genes was carried out, highlighting the production of synthetic insulin that, with the name of humulin, solved the problems generated from the use of swine insulin. In 1986 she completed the second postdoc with Dr. Caruthers at the University of Colorado at Boulder. In this laboratory, phosphoramidites were developed, which are the reagents used today for the production of synthetic DNA and RNA. Upon his return to Barcelona, ​​he joined the CSIC Research and Development Center where he organized the first research group in our country focused on oligonucleotide synthesis. In 1984 he moved to the European Molecular Biology Laboratory (EMBL) in Heidelberg (Germany) to direct for 5 years one of the most prestigious groups in DNA and RNA Chemistry in Europe. Upon his return to Barcelona, ​​he was part of the Barcelona Institute for Biomedical Research (IRB Barcelona) and was recognized as a group of excellence by the CIBER-BBN. In 2012 he moved to the IQAC-CSIC to occupy the direction of the institute until 2017.

The Nanomedicine Revolution

Yesterday, November, 25 took place, within the the program of the Ateneo of the EINA (School of Engineering and Architecture of Aragón), the online conference on “The Revolution of Nanomedicine” by Ramón Martínez Máñez.

The Conference chair, Jesús Martínez de la Fuente, Principal Investigator of the BIONANOSURF group of CIBER-BBN and the Institute of Nanoscience and Materials of Aragón, introduced the guest, Ramón Martínez Máñez, Scientific Director of CIBER-BBN, highlighting “his creativity in the use of his systems and how he combines them with different diagnostic release systems, combining organic chemistry, surface chemistry, applications in biotechnology and giving way to translation and transfer, his works are very unique“

Ramón Martínez Máñez, Scientific Director NANBIOSIS unit 26 NMR: Biomedical Applications II, gave a very instructive talke about what is nanotechnology and how nanotechnology revolution has reached the medicine, with current examples of the application of nanomedicines, as well as in the medicine of the future.

After it, a very interesting debate took place in which different issues were discussed, especially in relation to nanomedicine applied to therapy, such as the barriers to generalize the use of nanoparticles in therapy, the current state of implantation of nanoformulated drugs in the market and the advancement of the use of some nanoparticles as polymers or liposomes compared to inorganic nanoparticles, the degree of development of nanoparticles under GLP certification or why cancer is the main target of nanomedicine with a great difference over other pathologies. The audience asked questions that led to the discussion of some more controversial points such as whether it is true that “Big Pharma” does not like nanoparticles, why there is a regulatory vacuum regarding their use and how to solve these problems.

Regarding the diagnosis applications, Ramón Martínez commented that “nanotechnology already has its way open, both in the development of nanoparticles and systems to amplify the signal, based on nanophotonics, resonant rings or other technologies at the nanometric level. The pandemic has highlighted the importance of having rapid detection systems for bio parameters, pathogens, bacteria … We have a lot of knowledge acquired in recent years in these systems and they are currently being developed in a more or less short time, we are truly close to revolutionizing the field of detection“.

Finally, in realtion with the nanomedicine of the future, the questions raised in the debate revolved mainly around nanobots and their state of development or the problems that are emerging in it or the possibility of uniting nanomedicine with artificial intelligence and possible applications.

The Ateneo is an activity of the EINA in collaboration with the Aragón Engineering Research Institute and SAMCA Chair of Technological Development of Aragon, both directed by Pablo Laguna, Scientific Director of Nanbiosis U27 High Performance Computing. Pablo Laguna closed the event thanking Ramón Martínez Máñez and Jesús Martínez de la Fuente for their participation and highlighting the high number of attendees at the conference.

Nano-carrier to release drugs into damaged cells

Senescent cells are damaged cells that do not perform their normal roles anymore but that are not dead –hence they are commonly known as zombi cells. These cells interfere with the functioning of the tissue in which they accumulate. Senescence is a cell program that is triggered by many types of damage and senescent cells are present in many diseases. They accumulate in diverse types of tissues during aging, thus contributing to the progressive deterioration associated to aging. Eliminating these zombi cells is one of the challenges facing science today.

In the Cellular Plasticity and Disease lab headed by the ICREA researcher Manuel Serrano at the Institute for Research in Biomedicine (IRB Barcelona) and supported by “la Caixa” Banking Foundation, the researchers devise strategies to eliminate senescent cells. In a study published in EMBO Molecular Medicine, they present a proof of principle of a drug delivery system with selectivity for tissues that harbour senescent cells.

In collaboration with a team headed by Ramón Martínez-Máñez, Scientific Diirector of NANBIOSIS Unit 26 NMR: Biomedical Applications II ,  the IRB Barcelona scientists have exploited a particular hallmark of senescent cells in order to design a delivery system that specifically targets them. They have demonstrated its efficacy in cells in vitro and in two experimental mouse models, namely pulmonary fibrosis and cancer. These diseases are characterized by the presence of damaged cells, and in the case of cancer this is particularly true after treatment with chemotherapy.

In these models, the senescent cells take up the carrier more efficiently than other cells and once inside the cell the casing of the carrier degrades to release the drug cargo. When the nano-vehicles contained cytotoxic compounds, the senescent cells were killed and this resulted in therapeutic improvements in mice with pulmonary fibrosis or with cancer.

“This nano-carrier may pave the way for new therapeutic approaches for serious conditions, such as pulmonary fibrosis or to eliminate chemotherapy-induced senescent cells,” explains Manuel Serrano. Another outcome of this study is that these nano-carriers could be used for diagnostic tests of senescence as they can transport a fluorescent compound or marker.

This study, performed by IRB Barcelona in collaboration with the Universidad Politécnica de Valencia, CNIO, the University of Cambridge, CIBER-BBN, and the company Pfizer in the US, is a step towards achieving the capacity to eliminate senescent cells. Developing tools to specifically eliminate senescent cells is currently a central goal for many pharmaceutical companies, among them the one set up by Manuel Serrano himself together with Ramón Martínez-Máñez and José Ramón Murguia, Senolytic Therapeutics, which is located at the Barcelona Science Park and in Boston.

The study has been funded by “la Caixa” Banking Foundation, the Botín Foundation, the European Research Council, CRUK Cambridge Centre Early Detection Programme, the Ministry of Economy and Competitiveness/ERDFs and the Catalan Governmen
