Researchers of GRIB take part in the first major open source drug discovery trial

The prestigious journal PLoS Pathogens has just published an article on the results of the Malaria Box project, an initiative of the Medicines for Malaria Venture that has given free, open access to new families of antimalarial molecules to 200 laboratories from 30 countries. The purpose of the project is to encourage new pharmacological discoveries that make it possible to fight neglected diseases and other illnesses and has already initiated more than a dozen projects aimed at developing new drugs for various diseases.

The Systems Pharmacology group of GRIB (IMIM-UPF) led by Jordi Mestres, has participated in this extensive study to determine any safety issues with Malaria Box compounds deriving from their interaction with human proteins. 

"The global effort has led, not only to charactersing the mechanism of action of one third of the Malaria Box compounds as well as determining their potential toxicity and human safety indicators, but it has also identified new opportunities for reusing some of the compounds to develop new drugs for combatting babesiosis, toxoplasmosis, trypanosomiasis, cryptosporidiosis, schistosomiasis, and filariasis pathogens, among others, many of which have been neglected by the industry until now", explains Jordi Mestres.

Investigadores del GRIB participan en un estudio que investiga por primera vez la regulación de los genes en un primate mientras hiberna

En el estudio, publicado en la revista Genome Biology and Evolution, han participado José Luis Villanueva-Cañas y Mar Albà, investigador postdoctoral y jefe del grupo de investigación en genómica evolutiva del GRIB (IMIM-UPF), respectivamente, que han realizado la parte computacional y de análisis de datos, así como investigadores del Duke Lemur Center y de la Universidad de Duke.

En este trabajo se investiga por primera vez la regulación de los genes en primates hibernados, en concreto el lémur enano de cola gruesa (cheirogaleus medius), una especie excepcional muy poco estudiada y la única capaz de hibernar, subsistiendo con los lípidos que ha almacenado en la cola durante el resto del año. El trabajo además es uno de los pocos estudios sobre la hibernación que utiliza una técnica moderna llamada RNAseq que permite ver a nivel global qué genes se están expresando y cuantificarlos. 

Según el Dr. Villanueva-Cañas, actualmente investigador del Instituto de Biología Evolutiva (UPF-CSIC) "aparte del interés biológico, el estudio de la hibernación es muy interesante también desde el punto de vista médico, ya que estamos hablando de animales que disminuyen drásticamente su metabolismo (temperatura, respiración, ayunas, actividad cerebral, etc) a unos niveles que serían letales para especies sin esta adaptación" y añade "dado que encontramos muchos mamíferos capaces de hibernar sin un patrón claro, creemos que el ancestro común a todos los mamíferos quizá tenía la capacidad de hibernar. Esto querría decir que muchos de los genes involucrados están también presentes en humanos y sería cuestión de averiguar cuáles son y cómo podemos manipularlos por nuestros intereses". Los investigadores han encontrado 90 genes, que incluyen genes involucrados en el metabolismo de los lípidos, la regulación del apetito o los ritmos biológicos.

Jordi Mestres, membre del Scientific Advisory Board del portal Chemical Probes

Felicitem a Jordi Mestres, coordinador del grup de recerca en Farmacologia de Sistemes del GRIB (IMIM-UPF) que ha estat escollit membre del Scientific Advisory Board del portal Chemical Probes, una eina accessible des d'internet i gratuïta que permet als investigadors, abans de començar una recerca, buscar la sonda química més apropiada per al seu projecte. Les sondes químiques o chemical probes, són unes molècules molt petites que interaccionen amb múltiples proteïnes i que tenen un impacte molt gran en la recerca biomèdica ja que si són de baixa qualitat, poden generar resultats científics erronis. Conèixer la interacció d'aquestes petites molècules, és clau en el desenvolupament de fàrmacs més eficients i segurs.

Aquest innovador portal recomana als investigadors sondes químiques basades en les aportacions del Scientific Advisory Board, un grup d'experts en el camp de la biologia química, medicina química, farmacologia i camps relacionats, que estan qualificats per determinar les millors sondes químiques disponibles i establir pautes adequades per a la seva utilització.

Cancer cell lines predict drug response

Large-scale study could increase success rate of developing personalised cancer treatments

Research published in Cell has shown that patient-derived cancer cell lines harbour most of the same genetic changes found in patients' tumours, and could be used to learn how tumours are likely to respond to new drugs, increasing the success rate for developing new personalised cancer treatments.

David Tamborero and Núria López-Bigas, members of the Biomedical Genomics group of GRIB (UPF-IMIM) have participated on this international study led by scientists from the Wellcome Trust Sanger Institute, the European Bioinformatics Institute (EMBL-EBI) and the Netherlands Cancer Institute, discovering a strong link between many mutations in patient cancer samples, and the sensitivity to particular drugs. This could advance personalised cancer medicine by leading to results that help doctors predict the best available drugs, or the most suitable clinical trials for each individual patient.

In the first systematic, large-scale study to combine molecular data from patients, laboratory cancer cell lines and drug sensitivity, David Tamborero says: "one of the main difficulties of the study was to interpret the large amount of genomic alterations observed in the tumor cells', and continue: "our task was to identify the mutations that are important for the development of each of the cancers in order to associate them with the observed drug responses".

A new energy source within the cells

In a paper published in Science, researchers at the Centre for Genomic Regulation (CRG) led by group leader Miguel Beato in collaboration with Baldo Oliva and Jaume Bonet, head and postdoctoral researcher respectively of the Structural Bioinformatics group of GRIB (IMIM-UPF) and researchers of the IRB in Barcelona and the URV in Tarragona have described for the first time a new pathway generating energy within the cell nucleus for remodeling chromatin and reprogramming gene expression. They have also identified the function of enzymes involved at every step of this process and how they are activated in response to stress signals. Their results, will help in understanding the mechanisms underlying chromatin remodelling, its relationship with DNA damage and, by extension, with cancer. 

Exceptional situations call for extraordinary measures. When cells need to cope with a global reprogramming of gene expression they require a lot of energy in the nucleus. In these situations the cells block their mitochondrial and cytosolic ATP production to be focused on the main task in the nucleus," says Miguel Beato, principal investigator of this paper.
