INTRODUCTION. Several post-transcriptional processes jointly orchestrate gene expression at the RNA level. Among them, alternative splicing, a process of differentially combining exons and introns or their parts to generate multiple mRNA isoforms from a single gene, significantly expands the transcriptomic landscape of eukaryotic cells (1, 2).

Background. RNA silencing describes several mechanistically related pathways which are involved in controlling and regulating gene expression. RNA silencing pathways are associated with the regulatory activity of small non-coding RNAs (approximately 20–30 nucleotides in length) that function as factors involved in inactivating homologous sequences, promoting endonuclease activity RNA splicing links genetics to disease Many genetic variants associated with disease have no apparent effect on any specific protein coding sequence.

In this process, particular exons of a gene may be included within or excluded from the final, processed messenger RNA (mRNA) produced from that gene. Splicing occurs in the nucleus before the RNA migrates to the cytoplasm.

Aberrant splicing is a major cause of rare diseases. However, its prediction from genome sequence alone remains in most cases inconclusive. Recently, RNA sequencing has proven to be an effective complementary avenue to detect aberrant splicing.

RNA splicing represents a post-transcriptional mechanism to generate multiple functional RNAs or proteins from a single transcript. The evolution of RNA splicing is a prime example of the Darwinian function follows form concept. In this talk about RNA splicing, Phillip A. Sharp explains the seminal experiments he performed in the late 1970s that demonstrated the splicing of introns from newly transcribed RNA in human cells.

As DNA is transcribed into RNA it needs to be edited to remove non-coding regions, or introns, shown in green. 2020-05-06 2013-09-19 2020-03-18 2021-03-01 2019-12-01 Involved in the first step of pre-mRNA splicing. Required for cell growth and cell cycle control.

This pre-mRNA usually still contains introns, regions that will not go on to code for the final amino acid sequence. These are removed in the process of RNA splicing, leaving only exons, regions that will encode the protein. This exon sequence constitutes mature mRNA.

RNA splicing is an essential process that governs many aspects of cellular proliferation, survival, and differentiation. Considering the importance of RNA splicing in gene regulation, alterations in this pathway have been implicated in many human cancers. Alternative splicing, or alternative RNA splicing, or differential splicing, is a regulated process during gene expression that results in a single gene coding for multiple proteins. In this process, particular exons of a gene may be included within or excluded from the final, processed messenger RNA (mRNA) produced from that gene. Splicing occurs in the nucleus before the RNA migrates to the cytoplasm. Once splicing is complete, the mature mRNA (containing uninterrupted coding information), is transported to the cytoplasm where ribosomes translate the mRNA into protein.
