CRISPR technologies for Cystic Fibrosis treatment

Cystic fibrosis is an inherited genetic disease that mainly affects the lungs and the digestive system

On April 6, the first meeting was held, on the one hand, with people with Cystic Fibrosis and the Euskadi Cystic Fibrosis Association (Arnasa) and, on the other, with the NanoBioCel research group of the CIBER-BBN and the University of Basque Country, which is also part of the ICTS Nanbiosis through the Drug Formulation Unit U10.

The cooperative relationship between the NanoBioCel research group and Arnasa began approximately 5 years ago with the contributions made by the association to the NanBioCel group for research in cystic fibrosis.

The goup has focused on the development of non-viral vectors to address the treatment of cystic fibrosis through gene therapy. Progress is currently being made in the development of CRISPR technologies for its treatment.

This meeting was organized with the main objective of making those affected aware of the research carried out by NanoBioCel in cystic fibrosis and promoting associationism and collaboration between affected people and researchers to better understand the disease and find promising solutions.

The event was attended by almost 28 associates and many of the rest requested that the presentation of the researchers be recorded

Arnasa is the Cystic Fibrosis Association of the Basque Country and contributes with its work and activities to the promotion of general interest and the visibility of the disease, as well as to the improvement of the quality of life of people affected by the disease and their families.

NANBIOSIS renews its accreditation as Singular Scientific and Technical Infrastructure (ICTS)

The Minister of Science and Innovation, Diana Morant, chaired the XI meeting of the Council for Scientific, Technological and Innovation Policy, in which the update of the Map of Singular Scientific and Technical Infrastructures, the ICTS Map for 2021-2024, was approved.

The ICTS are facilities dedicated to cutting-edge research of the highest quality, as well as to the transmission, exchange and preservation of knowledge, technology transfer and the promotion of innovation.

The map has 29 ICTS distributed among all the territories, includes NANBIOSIS, the Infraestructure for Production and Characterization of Nanomaterials, Biomaterials and Systems in Nanomedicine with its 26 units.

As a novelty, the update incorporates four new nodes or infrastructures associated with the ICTS. Specifically, the NASERTIC computing node in Navarra, the CIEMAT computing node in Extremadura and Madrid, and the Port d’Informació Científica data node in Catalonia are incorporated into the ICTS Red Española de Supercomputación, while the Center for Microanalysis of Materials is associated as a node to the new distributed Infrastructure of Applications Based on Accelerators. Likewise, Navarra incorporates an infrastructure to this map for the first time, an instrument that improves the management of ICTS and helps these organizations to access funding from the Ministry as well as regional and European funds, particularly the ERDF funds and the Recovery Funds and Resilience (MRR).

In this sense, the minister announced that the next call to strengthen the ICTS, scheduled for the first half of 2022, will allocate 38 million euros until 2025 to finance lines of investment associated with the construction, development, instrumentation, equipment and improvement of its scientific- techniques. The previous call, published in 2021, dedicated nearly 37 million euros to these infrastructures.

NANBIOSIS is one of the five ICTS in the area of health sciences and biotechnology. This thematic area has significantly increased its representation in the current ICTS Map. Under the concept of distributed ICTS, infrastructure networks have been established in the field of imaging, nanotechnology and omics sciences. In addition, the high biological safety laboratories are also reinforced, expanding the infrastructures of this type that offer their services.

The coming revolution: synthetic DNA and RNA for therapeutic and diagnostic applications

The discovery of the mRNA vaccines for the treatment of coronavirus, as well as new medicines for the treatment of genetic diseases, has been important in the quest of solutions for undrugable diseases in an unexpected short-time.

Thus, the chemical modifications of nucleic acids with diagnostic and therapeutic purposes is now a reality, a revolution that promises to give hopes on unsolved medical problems or optimize previous approaches, largely due to the research push for the development of mRNA vaccines against SARS-CoV-2 infection.

Now, the prestigious The Chemical Recordjournal has invited the Nucleic Acids Chemistry group, of IQAC-CSIC and CIBER-BBN and belonging to the Global Health Platform of CSIC, to describe the advances and modificacions of the nucleic acids in the last decade. The article, authored by Dr. Carme Fàbrega, Dr. Anna Aviñó and Dr. Ramon Eritja (coordinator and director, respectively, of Unit 29 of ICTS NANBIOSIS), reports the development of synthetic DNA and RNA for therapeutic and diagnostic applications.

The article describes the most important results from the Nucleic Acid Chemistry group in this area covering the international context that surrounded these studies. These include the development of modifications in potentially therapeutic oligonucleotides to enhance nuclease resistance as well as improving cellular uptake and avoiding side effects, and the advances in the use of DNA nanostructures in the controlled deposition of matter in surfaces and their potential application as drug delivery systems is reported.

Moreover, the article has been selected to illustrate the front cover of The Chemical Record, a journal of the Chemical Society in Japan, with a suggestive image that shows the research activity in this area. The back image is the three dimensional reconstruction of a DNA array described by the group of Dr. Seeman obtained by A. Garibotti in Barcelona. On the top the crystal structure of the Argonaute protein from the Protein Data Bank is shown. This protein is a natural player that helps the therapeutic action of RNA molecules.

Abstract

Cardiovascular disease is an important cause of death in patients with chronic kidney disease (CKD). Protein-bound uremic toxins, such as p-cresyl and indoxyl sulfate (IS), are poorly removed during hemodialysis, leading to vascular endothelial dysfunction and leukocyte extravasation. These processes can be related to dynamic adhesion structures called podosomes. Several studies have  indicated the role of integrin-linked kinase (ILK) in the accumulation of integrin-associated proteins in podosomes. Here, we investigated the involvement of ILK and podosome formation in the adhesion and extravasation of monocytes under p-cresol (pc) and IS exposure. Incubation of THP-1 human monocyte cells with these toxins upregulated ILK kinase activity. Together, both toxins increased cell adhesion, podosome formation, extracellular matrix degradation, and migration of THP-1 cells, whereas ILK depletion with specific small interfering RNAs suppressed these processes. Interestingly, F-actin colocalized with cortactin in podosome cores, while ILK was colocalized in podosome rings under toxin stimulation. Podosome Wiskott-Aldrich syndrome protein (WASP)-interacting protein (WIP) and AKT protein depletion demonstrated that monocyte adhesion depends on podosome formation and that the ILK/AKT signaling pathway is involved in these processes. Ex vivo experiments showed that both toxins induced adhesion and podosome formation in leukocytes from wild-type mice, whereas these effects were not observed in leukocytes of conditional ILK-knockdown animals. In summary, under pc and IS stimulation, monocytes increase podosome formation and transmigratory capacity through an ILK/AKT signaling pathway-dependent mechanism, which could lead to vascular injury. Therefore, ILK could be a potential therapeutic target for the treatment of vascular damage associated with CKD.

Targeting of the breast cancer stem cells to improve the treatment of triple negative breast cancer

On April 1st PhD candidate Patricia Cámara Sánchez defended her doctoral thesis entitled “Targeting of the breast cancer stem cells to improve the treatment of triple negative breast cancer“, where ICTS-Nanbiosis Unit 20 participated in the in vivo assays. The thesis was supervised by Dr. Ibane Abasolo  (scientific director of Unit 20 from CIBER-BBN and VHIR). Nanbiosis was also present within the jury, with Dr. Ana Paula Candiota (scientific coordinator of Unit 25 from CIBER-BBN and UAB) acting as secretary.

Patricia Cámara graduated as biochemist, did the master’s degree in Translational Biomedical Research from VHIR-UAB. Shortly after, started the PhD, which was aimed at improving the treatment of very deadly subtype of breast cancer by using different nanoformulations to specifically target the cancer stem cells. The now doctor Cámara-Sánchez screened up to 20 small drugs with anti-cancer stem cell activity, found synergistic ratios with conventional chemotherapeutic agents, and finally developed polymeric micelles encapsulating selected drugs. During the discussion of the dissertation, the need of additional in vivo assays was highlighted, as well as the potential use of MR provided by the U25, to explore non-invasively the metabolomic differences between cancer stem cells and regular cancer cells.

‘I’m very grateful for the opportunity to have been part of this amazing project. It has been a very enriching experience’, she explains. ‘After 5 years of research, I finish the PhD feeling very proud of having contributed to the fight against this aggressive subtype of breast cancer’, she adds. From now on, new research lines will bring forward the synergies between both units of NANBIOSIS, reinforcing a collaboration started several years ago and reflected in joint papers.
