Two doctoral students of GRIB awarded with the Doctoral School PhD Extraordinary Prize of the PhD Programme in Biomedicine of the UPF

Seven PhD Extraordinary Awards have been given of a total of 75 PhD theses defended in the academic year 2014-2015. Albert Antolín and Maria Martí have been awarded with this extraordinary Prize of the PhD Programme in Biomedicine.

The thesis of Albert Antolín, directed by Dr. Jordi Mestres, head of the Systems Pharmacology Group of GRIB, was entitled "The Impact of Polypharmacology on Chemical Biology" and focused on the selectivity of small molecules on their target proteins and its implications on pharmacological safety.

The thesis of Maria Martí, directed by Dr. Manuel Pastor and Dr. Jana Selent, head and PI respectively of the PharmacoInformatics group of GRIB, was entitled "Ligand selectivity at GPCRs: from multi-target binding profiles to biased agonism" and focused on the detection of molecules that enable the development of more efficient and secure antipsychotic drugs.

Albert Antolín is currently a Marie Curie Tecniospring postdoctoral fellow at the Hospital del Mar Medical Research Institute (IMIM) and María Martí is currently a postdoctoral fellow at the Institute of Pharmaceutical Chemistry of the Philipps University of Marburg, Germany. We congratulate both for this award!

The PhD Extraordinary Prizes will be officially presented at the UPF Graduation Ceremony for master's and doctoral degrees that will take place on July 1st, 2016, at the Ciutadella Campus.

Scientists of GRIB find a new molecular mechanism involved in the development of cancer

Researchers of the Computational Genomics group of GRIB (UPF-IMIM) led by Eduardo Eyras, have discovered new alterations linked to cancer and have revealed the importance of the transcriptome in the development of tumours. For the first time, scientists have studied the variability of the cell transcriptome in several tumours at the same time, that is, not focusing on the DNA but on the products extracted from it. The results of the study have been published in the journal Genome Research.

Thanks to the bioinformatics tools developed by the research group, in record time and using limited computational resources, the scientists have been able to carry out a comprehensive analysis of the transcriptome of over 4,000 tumour samples from eleven different types of cancer taken from the TCGA project. This analysis shows that the proteins bound to the RNA are very often altered in human tumours and that these alterations determine the cell transcriptome and induce cell transformations related to the development of cancer. Until now, these alterations remained invisible to the methods used in major cancer genome analysis projects.

Scientists of GRIB find the cause of the accumulation of genetic mutations in certain regions of the genome of melanomas and lung cancers

Genetic mutations are changes in the DNA sequence that can cause errors in cell function, and in the worst case, their accumulation leads to serious diseases such as cancer. To avoid this, cells have mechanisms that are continuously detecting and repairing these changes, but which sometimes fail, resulting in the accumulation of mutations and the emergence of tumours . A scientific team of the Biomedical Genomics group of GRIB, led by Núria López-Bigas, has found, for the first time, the reason why mutations specifically accumulate in certain regions of the genome in cells of melanoma and lung cancer (adenocarcinoma and lung squamous cell carcinomas), two which are highly prevalent in the population. The results of this research appear published in the latest edition of journal Nature.

Thousands of genes from the umbilical cord change their activity in response to amniotic sac infection in preterm birth

A study published in the latest issue of Pediatric Research, the official journal of the American Pediatric Society (APS) and the European Society for Pediatric Research (ESPR), describes the largest molecular signature to date of the fetal inflammatory response (FIR), found in umbilical cord tissue from extremely preterm newborns. The research was conducted by Daniel Costa, paediatrician at the Hospital de Figueres (Figueres), and Robert Castelo, leader of the Functional Genomics group of the GRIB (IMIM-UPF).

According to the World Health Organization, one in every ten babies is born preterm. Thanks to the advances in perinatal medicine, extremely preterm babies increasingly survive premature birth. However, they often develop diseases of prematurity, such as perinatal brain damage amd more concretely, before birth about 30% of these newborns suffer an intra-amniotic infection that triggers an inflammatory response in the fetus, also known as the fetal inflammatory response (FIR), increasing their risk of disease and mortality.

In this study, Costa and Castelo conclude that Genes that increased their RNA molecular concentration are mainly involved in the activation of the innate and adaptive immune systems and constitute a valuable source of potential candidate FIR biomarkers . Genes that decreased their concentration, on the other hand, are mainly involved in fetal development, particularly brain development, and provide clues on possible molecular mechanisms leading to brain damage in FIR-affected preterm newborns

Regulating neuronal membrane lipids could be the key to Alzheimer's and Parkinson's

The work has been carried out using latest-generation molecular simulations The results will, in the future, enable new therapeutic pathways

A study published in the prestigious journal Scientific Reports from the Nature group demonstrates, for the first time and using computational tools, that polyunsaturated lipids can alter the binding rate of two types of receivers involved in certain nervous system diseases. The work was led by the Miguel Servet researcher Jana Selent and Ramon Guixà, members of the PharmacoInformatics group of GRIB (IMIM-UPF).

Using latest-generation molecular simulations, which are like "computational microscopes", the researchers have demonstrated that a decrease in polyunsaturated lipids in neuronal membranes, as seen in Parkinson's and Alzheimer's sufferers, directly affects the binding rate of dopamine and adenosine receptors. These are part of the family of receptors connected to the G protein (GPCR), located in the cell membrane and responsible for transmitting signals to within the cell. Until now, various studies have demonstrated that lipid profiles in the brains of people with diseases like Alzheimer's and Parkinson's are very different from those of healthy people. These studies showed that the levels of a polyunsaturated fatty acid in neuronal membranes are considerably lower in the brains of sufferers. The researchers believe that this difference in the lipid composition of membranes could alter the way in which certain proteins interact with each other, as in the case of the GPCR receivers.

The 2nd eTOX Hackathon starts today at PRBB

eTOX Hackathon will be celebrated from the 7th till 10th of March at the Barcelona Biomedical Research Park (PRBB). The objective of this event is to gather multidisciplinary teams from academic, SME and EFPIA partners to work on a number of specific cases that require close, hands-on collaboration between computational experts and toxicologists. The final goal of this exercise will be to mine the data collected in the project as well as other public sources in order to derive new in silico models for the prediction of the toxicity of drug candidates. The attendance confirmed to this event includes representatives of large pharmaceutical companies like Sanofi-Aventis, Bayer, Novartis and Roche, academia & research organisations such as FIMIM, Fraunhofer, CNIO and UPV, and SMEs Lead Molecular Design, Lhasa Ltd and Molecular Networks.
 
The eTOX project aims to develop a drug safety database from the pharmaceutical industry legacy toxicology reports and public toxicology data, innovative in silico strategies and novel software tools to better predict the toxicological profiles of small molecules in early stages of the drug development pipeline. The eTOX project is funded by the Innovative Medicines Initiative Joint Undertaking (IMI-JU), a unique partnership between the European Community and the European Federation of Pharmaceutical Industries and Associations (EFPIA) and coordinated by the GRIB (IMIM-UPF).
