Advances in Computational Biology Conference 2019

The first Advances in Computational Biology conference will bring together researchers working on systems biology, omics technologies, artificial intelligence and high-performance computing with applications to biology from both the public and private sectors. One of the main purposes of the conference is to visualize and promote the research done by women scientists and for this reason, all presenters will be women, although the conference is open to everyone. We want to create a space to foster collaborations between scientists, providing an excellent opportunity to share ideas and build research networks.  Mar Albà, head of the Evolutionary genomics group of GRIB is member of the organizing committee and Laura I. Furlong, head of the Integrative Bioinformatics group of GRIB is member of the scientific committee of the event.

Detecting Signs of Depression in Tweets in Spanish: Behavioral and Linguistic Analysis

Abstract: Mental disorders have become a major concern in public health, and they are one of the main causes of the overall disease burden worldwide. On the other hand, Social Media platforms allow us to observe thoughts and feelings of people's daily lives, including those of patients suffering from mental disorders. In this presentation we will discuss the usefulness of identifying the linguistic features of tweets in Spanish and the behavioral patterns of Twitter users who generate them, which could suggest signs of depression. Twitter users who are potentially suffering from depression modify the general characteristics of their language and the way they interact on social media. On the basis of these changes, these users can be monitored and supported, thus introducing new opportunities for studying depression and providing additional health care services to people with this disorder.

Interaction of Membrane Cholesterol with G Protein-Coupled Receptors: Novel Insights in Health and Disease

 G protein-coupled receptors (GPCRs) are the largest class of molecules involved in signal transduction across membranes, and represent major drug targets in all clinical areas.  The overall focus of our work is on the role of membrane cholesterol in GPCR organization (oligomerization), dynamics and function with implications in health and disease.  The GPCR of choice is the serotonin1A receptor, an important neurotransmitter receptor implicated in the generation and modulation of cognitive, behavioral and developmental functions, and an important drug target.  We demonstrated that membrane cholesterol is necessary for ligand binding, and G-protein coupling and signaling of serotonin1A receptors.   Interestingly, high-resolution crystal structures of GPCRs exhibit bound cholesterol.  In this context, we reported the presence of cholesterol recognition/interaction amino acid consensus (CRAC) motifs in the serotonin1A receptor.  Recent results employing mutations in the CRAC motifs show the importance of Lys101 in transmembrane helix II in conferring cholesterol-sensitivity to signaling by the receptor.  In addition, using a combination of experimental and MD simulation approaches, we demonstrated that the receptor is more stable and compact in the presence of membrane cholesterol.  Further, our results provide important insights in cholesterol-dependent oligomerization of the receptor using a variety of approaches such as photobleaching homo-FRET, photobleaching image correlation spectroscopy, and coarse grain MD simulations.  We ension that progress in deciphering molecular details of the nature of GPCR-cholesterol interaction in the membrane would lead to better insight into our overall understanding of GPCR function in health and disease.

III Retreat de l'IMIM

El dimecres 29 de maig tindrà lloc a l'Auditori del PRBB el III Retreat de l'IMIM. Amb aquesta iniciativa es vol donar visibilitat als projectes més rellevants que s'estan desenvolupant a cada Programa de Recerca, tot esperant que això sigui font de noves sinèrgies i d'intercanvi científic entre els diferents grups per a millorar la nostra competitivitat científica. És per aquest motiu que agrairíem us reservéssiu tota la jornada per assistir-hi, i així poder conèixer en què estan treballant els diferents grups de l'IMIM, fora del programa de recerca del que formeu part.el III Retreat de l'IMIM.

ResMarkerDB: a database of biomarkers of response to antibody therapy in breast and colorectal cancer

The clinical efficacy of therapeutic monoclonal antibodies for breast and colorectal cancer has greatly contributed to the improvement of patients' outcomes by individualizing their treatments. However, primary or acquired resistance may occur. Although several databases characterize biomarkers of drug response, there is a need of resources that offer this information to the user in a harmonized manner to support research and development of new alternative treatments. ResMarkerDB was developed as a comprehensive resource of biomarkers of drug response in breast and colorectal cancer. It integrates these data from existing repositories, and new data extracted and curated from the literature (referred as ResCur). It provides a user-friendly web interface (http://www.resmarkerdb.org) to facilitate the exploration of current knowledge of biomarkers of response in breast and colorectal cancer. The database contains more than 500 biomarker-drug-tumour associations. ResMarkerDB aims to enhance translational research efforts in identifying actionable biomarkers of drug response in cancer.

Uncovering de novo gene birth in baker's yeast with RNA-seq and ribosome profiling

De novo gene birth is a unique mechanism of new gene formation- unlike genes originating from duplication or fusion, de novo genes come from previously non-genic sequences-this potentially exposes completely novel peptides to selection. Several groups have previously investigated de novo gene birth in baker's yeast (Saccharomyces cerevisiae). Interestingly, many of these analyses have produced contrasting observations. To better understand the true origins of these de novo genes, we performed the first analysis of de novo gene birth in Saccharomycotina using transcriptomics data for eleven different species of yeast as well as ribosome profiling for S. cerevisiae (doi.org/10.1101/575837). We identified more than 200 putative de novo transcripts which often appear in regions overlapping older genes on the opposite strand.

Continual Reinforcement Learning in 3D Non-stationary Environments

Dynamic and always-changing environments constitute an hard challenge for current reinforcement learning techniques. Artificial agents, nowadays, are often trained in very static and reproducible conditions in simulation, where the common assumption is that observations can be sampled i.i.d from the environment. However, tackling more complex problems and real-world settings this can be rarely considered the case, with environments often non-stationary and subject to unpredictable, frequent changes. In this talk we discuss about a new open benchmark for learning continually through reinforce in a complex 3D non-stationary object picking task based on VizDoom and subject to several environmental changes. We further propose a number of end-to-end, model-free continual reinforcement learning strategies showing competitive results even without any access to previously encountered environmental conditions or observations.
