We are excited to share our latest article: " for newly sequenced organisms", published today in Nature Machine Intelligence: https://rdcu.be/cCVsT

In this paper we introduce S2F (sequence to function). A machine learning method that predicts protein function for organisms that have only sequence information.

The twist? We go beyond homology to do it!

By transferring protein-protein relationships from well studied organisms, we put together a functionally coherent network of proteins.

We use InterPro and HMMER predictions as a starting point. And these predictions are propagated and amplified on the network.

In development for many years, the project is open source https://github.com/paccanarolab/s2f

(PRs are welcome!)

An interactive explorer of our extensive testing is available in the project website:

Predicting the function of proteins in newly sequenced organisms is a challenging problem. Mateo Torres et al. present here a method to transfer the functional relations from known organisms and improve the prediction using network diffusion.

We present two complementary machine learning approaches for drug repositioning against COVID-19 that target SARS-CoV-2 and its cellular processes in the host, respectively. Our matrix decomposition approach exploits drug developmental information to predict broad-spectrum antivirals; our graph kern...

Our recent paper "Predicting the frequencies of drug side effects" featured in TechXplore! 🤓😍🙌 Read our paper here: https://rdcu.be/b64BK

A new algorithm has been developed by academics at Royal Holloway, University of London, to predict the side effects of drugs before they hit the market by using the same principle by which movies are recommended to users.

We are excited to share our on https://www.nature.com/articles/s41467-020-18305-y published in SpringerNature Nature Communications

Currently, the frequencies of drug side effects are determined in randomised controlled clinical trials. Here the authors develop an interpretable machine learning approach to predict the frequencies of unknown side effects for drugs with a small number of determined side effect frequencies.

Our new paper is out! Congratulations to our lab member Dr Juan Caceres for achieving the milestone of obtaining his doctoral degree!

Author summary The elucidation of the genetic causes of diseases is central to understanding the mechanisms of action of a pathology and the development of treatments. Disease gene prediction methods streamline the discovery of the molecular basis for a disease by prioritizing genes for experimental...

Prof. Alberto Paccanaro and his graduate student Ruben Jimenez were recently at the XLII Latin American Conference on Informatics (CLEI) & 46th Argentine Conference in Informatics (JAIIO) that was held in Cordoba, Argentina. PaccanaroLab research group presented three papers:
(i) Drug cocktail selection for the treatment of Chagas Disease: a multi-objective approach;
(ii) An exploratory analysis of drug target locality;
(iii) Mining the biomedical literature to predict shared drug targets in DrugBank.
Thanks for the invitation! We have a great time sharing our research!

Today was the Computer Science Annual Research Colloquium at Royal Holloway, University of London. Juan Caceres, Mateo Torres and Diego Galeano presented their research in short talks. Namely, "Predicting genes for molecularly uncharacterised diseases", "Gene pushing" and "Signatures of drug side-effects in human phenotype", respectively. Congratulations to the guys for their successful viva, and for winning the prize of best presentation during the colloquium.
