About This Topic

The discovery of DNA sequences intervening coding regions transformed the analysis of the protein expression. Not only RNA-intron structures matter, but also regulatory decisions guided by several protein/RNA factors that commit selected exons to be present at the final, processed mRNA. Alternative splicing (AS) may create multiple proteins with specific biological functions, synthetized from an initial pre-mRNA depending on inclusion/exclusion of accurately selected exons. In human cells, over 90% of transcripts are alternatively spliced and, consequently, AS amplifies 20,000 protein-coding genes to obtain many more proteins-isoforms as initially anticipated. In addition, multi-exonic pre-mRNAs normally are regulated by AS rendering isoforms with modulated role or even distinct function in specific tissues, development or the cell-cycle phases. The rate of AS is then crucial in the regulation of the gene expression. Trans-acting factors and cis-acting sites actively construct the lariats-structures to be excised which contain selected exon(s) to be skipped. The main role of the final lariats-structure, that decides which exons will be finally skipped, is clearly emphasized by the presence of RNA-helicases. Finally, misfunction of the AS mechanism may synthesize abnormal protein-isoforms seen in many genetic disorders and in development of cancer. Additionally, mutations either on cis- or trans-splicing factors are often observed in cancer processes.

Manuscript Submission Information

Manuscripts should be submitted through the LIDSEN Submission System. Detailed information on manuscript preparation and submission is available in the Instructions for Authors. All submitted articles will be thoroughly refereed through a single-blind peer-review process and will be processed following the Editorial Process and Quality Control policy. Upon acceptance, the article will be immediately published in a regular issue of the journal and will be listed together on the special issue website, with a label that the article belongs to the Special Issue. LIDSEN distributes articles under the Creative Commons Attribution (CC BY 4.0) License in an open-access model. The authors own the copyright to the article, and the article can be free to access, distribute, and reuse provided that the original work is correctly cited.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). Research articles and review articles are highly invited. Authors are encouraged to send the tentative title and abstract of the planned paper to the Editorial Office (genetics@lidsen.com) for record. If you have any questions, please do not hesitate to contact the Editorial Office.
