In order to comprehend the influence of evolutionary changes in gene structure on the alternative splicing mechanism, we work on three related subjects: (i) conservation of exonintron sequences, (ii) splice site score changes and (iii) length data changes, across the vertebrate tree. We have analyzed conservation levels of human Alternative cassette exons (ACEs) ...
The impact of AS (alternative splicing) is well-recognized in animal systems as a key regulator of gene expression and proteome complexity. In plants, AS is of growing importance as more genes are found to undergo AS, but relatively little is known about the factors regulating AS or the consequences of AS on mRNA levels and protein function. We have established an accurate and reproducible RT (...
Alternative splicing and polyadenylation were observed pervasively in eukaryotic messenger RNAs. These alternative isoforms could either be consequences of physiological regulation or stochastic noise of RNA processing. To quantify the extent of stochastic noise in splicing and polyadenylation, we analyzed the alternative usage of splicing and polyadenylation sites in Entamoeba histolytica usin...
Gene expression regulation relies on a variety of molecular mechanisms affecting different steps of a messenger RNA (mRNA) life: transcription, processing, splicing, alternative splicing, transport, translation, storage and decay. Light induces massive reprogramming of gene expression in plants. Differences in alternative splicing patterns in response to environmental stimuli suggest that alter...
Splicing and alternative splicing are major processes in the interpretation and expression of genetic information for metazoan organisms. The study of splicing is moving from focused attention on the regulatory mechanisms of a selected set of paradigmatic alternative splicing events to questions of global integration of splicing regulation with genome and cell function. For this reason, paralle...
Numerous mechanisms exploit or modulate the conformational/compositional dynamics of spliceosomes to regulate splicing. The majority of higher eukaryotic protein-coding genes contain more than one intron and the derived pre-mRNAs can be alternatively spliced. Diverse principles ensure the reliable identification of authentic splice sites while concomitantly providing flexibility in splice site ...
AS (alternative splicing) and its role in disease, especially cancer, has come to forefront in research over the last few years. Alterations in the ratio of splice variants have been widely observed in cancer. Splice variants of cancer-associated genes have functions that can alter cellular phenotype, ultimately altering metastatic potential. As metastases are the cause of approximately 90% of ...
