Integrative Biomedical Informatics

New generation biomarkers based on mechanistic insight into disease

The impact of the genomic revolution in the field of medicine has been enormous. The concept of personalized medicine has evolved to precision medicine, which aims to find better ways of defining diseases by relating conventional clinical-pathological diagnostic criteria with state-of-the-art molecular profiling methodologies. Besides, a more precise diagnostic of the disease, based on the description of their molecular mechanisms would allow creating innovative diagnostic, prognostic, and therapeutic strategies precisely tailored to each patient's requirements. To achieve this, a deeper, systems-based understanding of these disease drivers is required. Here I will discuss how primary gene expression and gene variation data can be integrated and transformed into mechanism-based biomarkers containing higher-level information on disease mechanisms by means of relatively simple models of functional pathways.

Nucleotide excision repair is impaired by binding of transcription factors to DNA

Somatic mutations are one of the major genetic alterations that contribute to the transformation of normal cell into cancer cell. The rate of somatic mutations appear in great variability across the genome due to chromatin organization, DNA accessibility and replication timing. However, other variables that may influence the mutation rate locally, such as DNA-binding proteins, are unknown. Here we demonstrate that the rate of somatic mutations in melanoma tumors is highly increased at active transcription factor binding sites and nucleosome embedded DNA compared to their flanking regions due to impaired nucleotide excision repair activity.

Computational RNA Biology

Exploiting processing patterns to study small non-coding RNAs

Small non-coding RNAs play a vital role in several cellular processes. Their pattern of processing and its traces in short RNA-Seq reads data is a powerful and unbiased resource that can be used to study those important molecules. Here we present a collection of software tools based on the analysis of processing patterns for the discovery, annotation and characterization of small non-coding RNAs.

GPCR drug discovery

Long non-coding RNAs as a source of new peptides.

High throughput sequencing of the eukaryotic transcriptome has resulted in the identification of many transcripts that lack long conserved open reading frames and which have been classified as long non-coding RNAs (lncRNAs). The majority of them are expressed at low levels and do not have a known function. Despite having been annotated as non-coding RNAs, the sequencing of ribosome-protected RNA fragments (ribosome profiling) has revealed that many of them are scanned by ribosomes and are likely to translate short peptides. We have examined single nucleotide polymorphism (SNP) data and have found evidence of purifying selection on the corresponding coding regions. We propose that lncRNAs provide the necessary raw material for the evolution of new functional proteins during evolution.

Computational RNA Biology

RNA processing alterations as drivers and prognostic markers of cancer

Abstract:

Alterations in RNA processing are emerging as important signatures to understand tumor formation and to develop new therapeutic strategies. However, it is not yet known the extent to which these alterations can be considered drivers or whether specific patterns of RNA processing can be predictive of prognosis. We describe our efforts to determine the functional impact and relevance in cancer of RNA processing alterations measured in 11 cancer types. We describe multiple alterations in RNA regulatory proteins and their target genes, and investigate RNA alterations that are predictive of tumor stage and survival. These novel signatures expand the catalogue of candidate actionable alterations in tumors and potentially complement current strategies in precision cancer medicine.

Identification of recently evolved genes in human and chimpanzee using deep

For a very long time, major mechanisms driving the evolution of new genes were thought to be restricted to gene duplication or rearrangements in existing protein-coding material. Nevertheless, recent comparative genomic analyses have shown that some genes are originated de novo from previously non-functional genomic sequences. These recently evolved genes may be related with the emergence of species or lineage specific adaptations.
