Alternative splicing, an important mechanism for understanding cancer

Using data for more than 4,000 cancer patients from The Cancer Genome Atlas (TCGA project), a team led by Eduardo Eyras, ICREA research professor at the UPF and head of the Computational RNA Biology group of GRIB (IMIM-UPF) jointly with the Sanford Burnham Prebys Medical Discovery Institute in San Diego has analyzed the changes in alternative splicing that occur in each tumor patient and studied how these changes could impact the function of genes. The results of the study, published in the journal Cell Reports, show that alternative splicing changes lead to a general loss of functional protein domains, and particularly those domains related to functions that are also affected by genetic mutations in cancer patients.

"Thanks to our previous research, we know that tumor type and stage can be predicted by observing alterations in alternative splicing", says E.Eyras, and adds, "with this new study, we have discovered that changes in alternative splicing that occur in cancer impact protein functions in a way that is similar to that previously described for genetic mutations".

40 Million EUR european project for new drug safety assessment and integrative data analysis research

The five-year project eTRANSAFE: Enhancing Translational Safety Assessment through Integrative Knowledge Management, aims to develop an advanced data integration infrastructure together with innovative computational methods to improve the security in drug development process and is funded by the Innovative Medicines Initiative (IMI 2) together with the pharmaceutical industry.

The eTRANSAFE consortium is a private and public partnership of 8 academic institutions, 6 SMEs and 12 pharmaceutical companies, and is coordinated by the Fundació Institut Mar d'Investigacions Mèdiques (IMIM) and led by the pharmaceutical company Novartis. Universitat Pompeu Fabra and Synapse Research Management Partners are partners of the Consortium. 

Based on the experience gained in the previous eTOX project, the eTRANSAFE project will carry out key efforts in the field of data standardisation and quality control, promoting the development and implementation of relevant data sharing policies and procedures that will have a great global impact in the community. eTRANSAFE will catalyse the transformation of drug safety modelling from monolithic applications and isolated data repositories to an open innovation ecosystem based on open standards, modular components and data integration services.

Professor Ferran Sanz, coordinator of the project said: "eTRANSAFE will improve translational safety assessment and contribute to the key scientific policies, such as the reduce, replace, refine (3Rs) one and the FAIR principles for data sharing."

Supporting public-private partnerships in genomics and health

Over 80 participants from industry and academia gathered in Barcelona on 6-7 June for the ELIXIR Innovation and SME forum. Hosted by ELIXIR Spain, the two-day event showcased successful companies making use of public bioinformatics resources, and presented free bioinformatics resources available through ELIXIR and ELIXIR Spain.

The programme included presentations of ELIXIR and ELIXIR Spain resources as well as companies and SMEs active in bioinformatics, genomics and health research. Three keynotes each presented different aspects of working with open data in life science research: Roderic Guigo from the CRG gave a general overview of the Open data in genomics including the European Genome-phenome ArchiveFerran Sanz, director of GRIB (IMIMUPF) and participant of ELIXIR Spain, showed several examples of how bioinformatics can support pharmaceutical research; and David Henderson from Bayer AG  talked about reuse of biomedical data in pharmaceutical research. Colm Carroll from the Innovative Medicines Initiative (IMI) presented some of the future funding opportunities in this area

Scientists reveal for the first time the details of protein association at the atomic level

The groups of Frank Noé at Freie Universität Berlin, and Gianni de Fabritiis, ICREA research professor and head of the Computational Biophysics group of GRIB ( IMIM- UPF), have now collaborated to produce what is the first atomic-detail computer simulation of the process of protein-protein association and dissociation. The results were published in the scientific journal Nature Chemistry and were validated with experimental data.

The main challenge was that atomic-detail molecular dynamics are incredible expensive to simulate. Key to the success of the Berlin-Barcelona team was the combination of several new technologies that enabled a "divide and conquer" approach to the problem. GPUGRID, a distributed network developed by De Fabritiis' group was employed to collect compute time on graphic processing units (GPUs) from Nvidia by volunteers around the globe. Thousands of short simulations were conducted that way, coordinated by a novel machine learning algorithm in such way that the overall protein association process could be simulated within one year instead of having to wait 10,000 years. Markov modeling, a method pioneered by Noé and colleagues, was used to combine the many short simulations to an overall dynamical model that describes protein association and dissociation in full detail. "This was clearly a risky but important proof of principle and we are happy that we managed to show that the simulations are able to capture associations between proteins", says De Fabritiis.

This achievement opens the door to understanding the details of viral infections, the inner workings of the immune system, and many other problems with biomedical or biotechnological relevance.

Formation of a GPCR signaling complex with arrestin


How proteins find each other to form signaling complexes

A study led by Jana Selent, head of the GPCR drug discovery group of GRIB (IMIM-UPF) and Martha Sommer (Institute of Medical Physics and Biophysics at the Faculty of Medicine in Charité Hospital, Berlin) published in the journal Nature Communications, focused on how G-protein-coupled receptors (GPCRs) and arrestin form complexes. The human GPCR family is an important class of targets for nearly half of all medicines prescribed today with the majority being involved in sensory and neuronal processes. Complex formation with intracellular signaling proteins such as arrestin is critical for many bodily processes. In this context, the published study identifies a previously unknown binding element critical to GPCR-arrestin interaction. Using a combination of computer simulations and site-directed fluorescence spectroscopy, the researchers were able to show that loops within the C-edge of arrestin are anchored to the membrane while forming pre- and high affinity complexes with GPCRs.  This discovery opens up a whole new field of research regarding how the membrane influences formation of GPCR signaling complexes with arrestin. Ultimately, these insights can be exploited for proposing new strategies to modulate this important class of drug targets.
