Introduction Prohibitin is an antiproliferative protein (1) and may function as a tumor suppressor through interaction with the retinoblastoma tumor suppressor protein and its family members (2). In addition, somatic mutations have been identified in human cancers, including breast cancer (3, 4). Interestingly, the prohibitin 3 UTR exhibits the characteristics of a trans-acting regulatory RNA t...

ADAMTS1 (a disintegrin and metalloproteinase with thrombospondin motifs 1) is an inflammatory-induced gene. We have previously reported that ADAMTS1 was strongly but transiently expressed in the infarcted heart. In this study, we investigated whether a 3'-untranslated region (UTR) affects the mRNA stability of this gene. When stimulated with tissue necrosis factor (TNF)-alpha, the expression le...

BACKGROUND Mature microRNAs (miRNAs) are single-stranded RNAs that regulate post-transcriptional gene expression. In our previous study, we have shown that versican 3'UTR, a fragment of non-coding transcript, has the ability to antagonize miR-199a-3p function thereby regulating expression of the matrix proteins versican and fibronectin, and thus resulting in enhanced cell-cell adhesion and orga...

Considerable insights into important cis regulatory elements in a gene can be gleaned from the identification of sequence homologies among different species. To extend and optimize the sequence comparison between human and mouse erythropoietin (Epo) genes, we have obtained new human sequence from 5,547 to 385 bp upstream of the cap site and extended the 3' flank by 489 bp. In addition, we have ...

Iron regulates the synthesis of two proteins critical for iron metabolism, ferritin and the transferrin receptor, through novel mRNA/protein interactions. The mRNA regulatory sequence (iron-responsive element (IRE)) occurs in the 5'-untranslated region of all ferritin mRNAs and is repeated as five variations in the 3'-untranslated region of transferrin receptor mRNA. When iron is in excess, fer...

A potyvirus was found causing yellow mosaic and veinal banding in sweetpepper in Central and Southeast Brazil. The sequence analysis of the 3′ terminal region of the viral RNA revealed a coat protein of 278 amino acids, followed by 275 nucleotides in the 3′-untranslated region preceding a polyadenylated tail. The virus shared 77.4% coat protein amino acid identity with Pepper severe mosaic viru...

OBJECTIVE The results from the published studies on the association between prohibitin 3' untranslated region C > T gene polymorphism and cancer risk are conflicting. This meta-analysis was performed to evaluate the relationship with cancer susceptibility overall, and to explore whether the T allele or TT genotype could become a predictive marker for cancer risk. METHODS Association studies w...

The results demonstrated that pancreatic ductal carcinoma (PDAC) of the body/tail was associated with more transcriptional and genomic changes, correlated worse prognosis, than PDAC head. different mutation types gene expression tumour locations provide deep insight into carcinogenesis or metastasis PDAC, suggest early diagnostic therapeutic strategies. SNV, single-nucleotide variations; NLS, N...

Secretion of an intracellular protein from a cell factory requires as a first step the redirection of the mRNA for synthesis of the protein on the endoplasmic reticulum. The feasibility of retargeting a mRNA coding for an intracellular protein to the endoplasmic reticulum was investigated using Ltk- fibroblasts stably transfected with gene constructs in which rabbit beta-globin coding region an...

Eukaryotic gene expression is precisely regulated at all points between transcription and translation. In this review, we focus on translational control mediated by the 3'-untranslated regions (UTRs) of mRNAs. mRNA 3'-UTRs contain cis-acting elements that function in the regulation of protein translation or mRNA decay. Each RNA binding protein that binds to these cis-acting elements regulates m...
