Regulation of pre-mRNA processing in human diseases.

Description of Research

The research of the Human Molecular Genetics group is focused on normal and pathological pre-mRNA processing with the aim to identify novel therapeutic strategies for correction of splicing defects.
We are exploring the molecular basis of splicing defects associated to coagulation deficiencies (hemophilia), cystic fibrosis, Spinal Muscular Atrophy and Netherton Syndrome. Our major interest is understanding how defects in non canonical splicing regulatory elements induce aberrant processing of pre-mRNA and develop appropriate strategies for splicing correction. We recently found that precise engineering of the U1 core spliceosomal RNA particle has a therapeutic potential in pathologies associated to exon-skipping mutations. Modified variants of U1 snRNA (Exon Specific U1 snRNAs) that binds by complementarity to intronic sequences downstream the 5'ss can correct exon skipping defects caused by different types of mutations. We are exploring this novel therapeutic strategy in cellular and animal models of coagulation defects, of Spinal Muscular Atrophy and Netherthon syndrome and understand the molecular mechanism involved. Part of the work is also dedicated to the analysis of a novel class of pri-miRNAs we have recently identified, whose hairpins present on pre-mRNA overlap with the splice site (Splice Site Overlapping miRNA) .
