Sarcomeric dysfunction in heart failure.
Sarcomeric dysfunction plays a central role in reduced cardiac pump function in heart failure. This review focuses on the alterations in sarcomeric proteins in diseased myocardium that range from altered isoform expression to post-translational protein changes such as proteolysis and phosphorylation. Recent studies in animal models of heart failure and human failing myocardium converge and indi...
متن کاملHeart failure-associated changes in RNA splicing of sarcomere genes.
BACKGROUND Alternative mRNA splicing is an important mechanism for regulation of gene expression. Altered mRNA splicing occurs in association with several types of cancer, and a small number of disease-associated changes in splicing have been reported in heart disease. However, genome-wide approaches have not been used to study splicing changes in heart disease. We hypothesized that mRNA splici...
متن کاملRNAcatalyses nuclear pre-mRNA splicing
In nuclear pre-messenger RNA splicing, introns are excised by the spliceosome, a dynamic machine composed of both proteins and small nuclear RNAs (snRNAs). Over thirty years ago, after the discovery of self-splicing group II intron RNAs, the snRNAswere proposed to catalyse splicing. However, no definitive evidence for a role of either RNAor protein in catalysis by the spliceosome has been repor...
متن کاملMechanisms of fidelity in pre-mRNA splicing.
The pre-mRNA splicing machinery consists of five small nuclear RNAs (U1, U2, U4, U5 and U6) and more than fifty proteins. Over the past year, important advances have been made in understanding how these factors function to achieve fidelity in splicing. Of particular note were the discoveries that the splicing factor U2AF(35) recognizes the AG dinucleotide at the 3' splice site early in spliceos...
متن کاملEpigenetics in Alternative Pre-mRNA Splicing
Alternative splicing plays critical roles in differentiation, development, and disease and is a major source for protein diversity in higher eukaryotes. Analysis of alternative splicing regulation has traditionally focused on RNA sequence elements and their associated splicing factors, but recent provocative studies point to a key function of chromatin structure and histone modifications in alt...
