NANO TECHNOLOGIES AND MICROENCAPSULATION course

Next October 15-18, the researchers of NANBIOSIS U12, Nanostructured liquid characterization unit, are giving a course on Nano Technologies and Microencapsulation organized by CSIC General Foundation and CUIMPB – Center Ernest Lluch of the Menéndez Pelayo International University (UIMP) in Barcelona.

The nano- and microencapsulation consists in the protection of active substances inside nano- and microcarriers, particularly labile molecules, improving their stability, with the aim of transporting them and achieving their controlled release. This topic is the subject of great interest in numerous fields and industrial applications. It is known that the performance efficiency of an active substance greatly increases with its encapsulation, depending on the size of the capsules, their transfer surface and the permeability properties of said capsules. In addition, the capsules can be directed specifically inside an organism, using suitable vectors.
The object of the course is to provide attendees with the basics of micro- and nanoencapsulation techniques, including fundamentals and preparation methods, as well as innovative applications in the chemical, cosmetic and pharmaceutical fields, among others.

The registration form and detailed information can be found on the CUIMPB website

AKT2 as a promising target for future anti-cancer therapies

The researchers of NANBIOSIS U20, led by Ibane Abásolo and Simó Schwartz have published a new article on the scientific magazine Cancers, with the title Pivotal Role of AKT2 during Dynamic Phenotypic Change of Breast Cancer Stem Cells

All the in vivo studies were performed by NANBIOSIS U20 In Vivo Experimental Platform.

Therapeutic resistance seen in aggressive forms of breast cancer remains challenging for current treatments. More than half of the patients suffer from a disease relapse, most of them with distant metastases. Cancer maintenance, resistance to therapy, and metastatic disease seem to be sustained by the presence of cancer stem cells (CSC) within a tumor. The difficulty in targeting this subpopulation derives from their dynamic interconversion process, where CSC can differentiate to non-CSC, which in turn de-differentiate into cells with CSC properties. Using fluorescent CSC models driven by the expression of ALDH1A 1(aldehyde dehydrogenase 1A1), we confirmed this dynamic phenotypic change in MDA-MB-231 breast cancer cells and to identify Serine/Threonine Kinase 2 (AKT2) as an important player in the process. To confirm the central role of AKT2, we silenced AKT2 expression via small interfering RNA and using a chemical inhibitor (CCT128930), in both CSC and non-CSC from different cancer cell lines. Our results revealed that AKT2 inhibition effectively prevents non-CSC reversion through mesenchymal to epithelial transition, reducing invasion and colony formation ability of both, non-CSC and CSC. Further, AKT2 inhibition reduced CSC survival in low attachment conditions. Interestingly, in orthotopic tumor mouse models, high expression levels of AKT2 were detected in circulating tumor cells (CTC). These findings suggest AKT2 as a promising target for future anti-cancer therapies at three important levels: (i) Epithelial-to-mesenchymal transition (EMT) reversion and maintenance of CSC subpopulation in primary tumors, (ii) reduction of CTC and the likelihood of metastatic spread, and (iii) prevention of tumor recurrence through inhibition of CSC tumorigenic and metastatic potentia

Scientific breakthrough against the problems of advanced age in fertility.

Researchers of CCMIJU. led by Javier G. Casado, Scientific Director of NANBIOSIS U14 Cell Therapy, are coauthors of the article “Extracellular vesicles derived from endometrial human mesenchymal stem cells enhance embryo yield and quality in an aged murine model” published by. Biology of Reproduction,

The study of the beneficial effect of endometrial stem cell exosomes on embryonic quality has been developed in NANBIOSIS U14 and in collaboration with U22 and U23

Advanced age is a risk factor undermining women’s fertility. Hence, the optimization of assisted reproduction techniques is an interdisciplinary challenge that requires the improvement of in vitro culture systems. Here, we hypothesize that supplementation of embryo culture medium with extracellular vesicles from endometrial-derived mesenchymal stem cells (EV-endMSCs) may have a positive impact on the embryo competence of aged oocytes. In this work, 24 weeks old B6D2 female mice were used as egg donors and in vitro fertilization assays were performed using males from the same strain (8–12 weeks); the presumptive zygotes were incubated in the presence of 0, 10, 20, 40, or 80 μg/ml of EV-endMSCs. The results from the proteomic analysis of EV-endMSCs.

In summary, the supplementation of embryo culture medium with extracellular vesicles from endometrialderived mesenchymal stem cells increases the quality of aged embryos.

Nanomol group initiates contact with the AEMPS to bring a new treatment against venous leg ulcers to the clinic

Researchers of the Nanomol group, ICMAB-CSIC and CIBER-BBN members of the ICTS “NANBIOSIS”, specifically of the Biomaterial Processing and Nanostructuring unit (U6), together with the company Nanomol Technologies S.L. have begun a consultation process with the Spanish Association of Medicines and Health Products (AEMPS) to try and enter a new treatment in a clinical studies stage, to fight against venous ulcers in lower extremities. The study is carried out within the framework of the RIS3CAT NANONAFRES project.

Approximately, 80% of ulcers in lower extremities have associated pathologies of venous insufficiency and these wounds are usually recurrent. An open ulcer can take from weeks to years to close, increasing the risk of mortality and affecting the quality of life of patients who suffer from them, mostly elderly people. The solution proposed within the NANONAFRES project consists of a medicine for topical application based on the incorporation of a biomolecule, with skin regenerating activity, encapsulated in nanoparticles. This approach ensures the protection of the active substance, preventing its degradation, while allowing the controlled and direct release of the drug in the area of the ulcer.

The NANONAFRES project, led by Nanomol Technologies SL, was born from the collaboration of the Nanomol group from ICMAB-CSIC with the companies Nanomol Technologies and BIOMED-LEITAT, the primary care centres EAP Osona Sur-Alt Congost SLP and the EAP Vallcarca-Sant Gervasi, public hospitals such as the Terrassa Health Consortium and the Maresme Health-Consortium Foundation and international research centres such as the Centro de Ingeniería Genética y Biotecnología de Cuba. This project, awarded with a RIS3CAT fund sponsored by the Generalitat of Catalonia, has a budget of 2.3 million euros and a duration of 3 and a half years.

This first consulting meeting with the AEMPS is a very important milestone in the process of developing any drug, in order to carry out clinical trials and transfer the system to the market, and thus bring the proposed treatment to the people who need it.

This approach will improve the effectiveness of current venous ulcers treatments, as well as the quality of life of patients, reducing the cost of medicines available today. In addition, the Nanomol group already has an internationally granted patent on this product, which demonstrates the novelty of this system and strengthens its position to reach the market through the partners present in this consortium and, in particular, through its spin-off Nanomol Technologies S.L.
