Alternative polyadenylation of cyclooxygenase-2
A biologically important human gene, cyclooxygenase-2 (COX-2), has been proposed to be regulated at many levels. While COX-1 is constitutively expressed in cells, COX-2 is inducible and is upregulated in response to many signals. Since increased transcriptional activity accounts for only part of the upregulation of COX-2, we chose to explore other RNA processing mechanisms in the regulation of ...
متن کاملAlternative Polyadenylation in Human Diseases
Varying length of messenger RNA (mRNA) 3'-untranslated region is generated by alternating the usage of polyadenylation sites during pre-mRNA processing. It is prevalent through all eukaryotes and has emerged as a key mechanism for controlling gene expression. Alternative polyadenylation (APA) plays an important role for cell growth, proliferation, and differentiation. In this review, we discuss...
متن کاملAlternative Polyadenylation: Methods, Findings, and Impacts
Alternative polyadenylation (APA), a phenomenon that RNA molecules with different 3' ends originate from distinct polyadenylation sites of a single gene, is emerging as a mechanism widely used to regulate gene expression. In the present review, we first summarized various methods prevalently adopted in APA study, mainly focused on the next-generation sequencing (NGS)-based techniques specially ...
متن کاملAlternative polyadenylation: new insights from global analyses.
Recent studies have revealed widespread mRNA alternative polyadenylation (APA) in eukaryotes and its dynamic spatial and temporal regulation. APA not only generates proteomic and functional diversity, but also plays important roles in regulating gene expression. Global deregulation of APA has been demonstrated in a variety of human diseases. Recent exciting advances in the field have been made ...
متن کاملTranscriptional activity regulates alternative cleavage and polyadenylation
Genes containing multiple pre-mRNA cleavage and polyadenylation sites, or polyA sites, express mRNA isoforms with variable 3' untranslated regions (UTRs). By systematic analysis of human and mouse transcriptomes, we found that short 3'UTR isoforms are relatively more abundant when genes are highly expressed whereas long 3'UTR isoforms are relatively more abundant when genes are lowly expressed....
