​Project EU-ToxRisk and US Initiative Tox21 new collaboration

The EU-ToxRisk project and the Toxicology in the 21st Century (Tox21) initiative in the US have agreed to collaborate on efforts to reduce the use of animals and achieve more efficient chemical safety assesments. A total of 28 representatives from both projects gathered in a workshop held in Mainz (Germany) on the 12th-14th September 2016 to initiate collaboration across areas of mutual interest within the field of risk assessment.

Two groups of GRIB participate in the EU-ToxRisk project coordinating the application of computational methods: the PharmacoInformatics group led by Manuel Pastor and the Integrative Bioinformatics group led by Ferran Sanz, and therefore will play a major role in this collaboration. In particular, the GRIB will participate in the joint development and validation of core methodologies for hazard and risk assessment, as read-across, quantitative AOP and similarity metrics.

You can find further information in the EU-ToxRisk-Tox21 joint Press Release (in english) and the translation into catalan and spanish at the UPF website.

Una eina web per ajudar a detectar mutacions cancerígenes

Els correctes tractament i diagnòstic del càncer depenen cada vegada més de l'anàlisi genètica dels pacients. En aquesta anàlisi es busquen alteracions en l'ADN del tumor, anomenades mutacions, que puguin tenir un valor diagnòstic, pronòstic o terapèutic per a la malaltia. Per poder identificar aquestes mutacions s'ha de seqüenciar l'ADN del tumor, ja sigui abastant tot el seu genoma, el seu exoma (és a dir, la part funcional del genoma) o bé només certs gens o regions gèniques, que s'inclouen en panells. La seqüenciació mitjançant panells presenta avantatges respecte a la seqüenciació de tot el genoma o exoma perquè, a més de comptar amb un coeficient de cost / benefici millor, els panells detecten menys falsos positius gràcies a la seva major sensibilitat.

El grup de Genòmica Biomèdica del GRIB (IMIM-UPF), ha creat OncoPaD, la primera eina web oberta a tota la comunitat científica per dissenyar panells de seqüenciació per càncer que tenen en compte el coneixement previ rellevant al tipus de tumor d'interès i el cost/benefici estimat pot ser ajustat pels investigadors. Segons els autors de l'estudi "mitjançant una interfície senzilla i intuïtiva, OncoPaD identifica quins gens o regions són els millors candidats per al disseny d'un panell específic, basant-se en l'associació coneguda dels gens amb mecanismes de desenvolupament del càncer o resposta a fàrmacs contra aquest i maximitzant el seu coeficient de cost /benefici" i també "a causa de la important necessitat que cobreix i la facilitat de la seva utilització, OncoPaD hauria d'esdevenir una eina d'ús freqüent per part d'investigadors clínics i translacionals d'oncologia". L'estudi ha estat publicat a la revista Genome Medicine.

Cellular stress activates an important anti-cancer protein

Researchers at UPF have discovered that the RB protein, responsible for stopping cell proliferation and therefore preventing tumor formation, is activated under cellular stress. The Structural Bioinformatics group of GRIB led by Baldo Oliva has participated on this work led by Eulàlia de Nadal and Francesc Posas, leaders of the research group on Cell Signaling of the UPF.

The study has been published in the journal Molecular Cell and shows that RB is also important to stop cell progression in response to cellular stress. Under these conditions, the brake is essential for cell survival. A very remarkable fact is that this new mechanism predominates over others that normally regulate the activity of RB. Therefore, the external activation of this mechanism could be used to block cell division.

As Francesc Posas, co-leader of the study says, "this discovery may be relevant in cancer biology because RB is a key protein in cell proliferation and many types of tumor coincide on the inactivation of this protein. If we get to reverse this inhibition, we could stop proliferation."

Researchers of GRIB participate in a crowdsourced assessment of the treatment response in rheumatoid arthritis

The researchers of the Structural Bioinformatics group of GRIB (IMIM-UPF), led by Baldo Oliva, recently participated in the Reumatoid Arthritis (RA) Responder challenge in which participants had to identify individuals most likely to fail response to RA therapies. The study was awarded with the first prize, it was presented at the Seventh Annual RECOMB/ ISCB Conference and has been eventually published at the Nature Communications magazine. 

Rheumatoid Arthritis (RA) is a debilitating autoimmune disease that affects millions world-wide and manifests through proinflammatory joint damage. Reducing inflammation is essential to prevent long-term deleterious effects in RA.

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.
