Destabilization of ERBB2 transcripts by targeting 3' untranslated region messenger RNA associated HuR and histone deacetylase-6.
In addition to repressing ERBB2 promoter function, histone deacetylase (HDAC) inhibitors induce the accelerated decay of mature ERBB2 transcripts; the mechanism mediating this transcript destabilization is unknown but depends on the 3' untranslated region (UTR) of ERBB2 mRNA. Using ERBB2-overexpressing human breast cancer cells (SKBR3), the mRNA stability factor HuR was shown to support ERBB2 t...
متن کاملRegulation of AUF1 expression via conserved alternatively spliced elements in the 3' untranslated region.
The A+U-rich RNA-binding factor AUF1 exhibits characteristics of a trans-acting factor contributing to the rapid turnover of many cellular mRNAs. Structural mapping of the AUF1 gene and its transcribed mRNA has revealed alternative splicing events within the 3' untranslated region (3'-UTR). In K562 erythroleukemia cells, we have identified four alternatively spliced AUF1 3'-UTR variants, includ...
متن کاملSequences at the 3' untranslated region of bamboo mosaic potexvirus RNA interact with the viral RNA-dependent RNA polymerase.
The 3' untranslated region (UTR) of bamboo mosaic potexvirus (BaMV) genomic RNA was found to fold into a series of stem-loop structures including a pseudoknot structure. These structures were demonstrated to be important for viral RNA replication and were believed to be recognized by the replicase (C.-P. Cheng and C.-H. Tsai, J. Mol. Biol. 288:555-565, 1999). Electrophoretic mobility shift and ...
متن کاملWoodchuck post-transcriptional element induces nuclear export of myotonic dystrophy 3' untranslated region transcripts.
The woodchuck post-transcriptional regulatory element (WPRE) can naturally accumulate hepatitis transcripts in the cytoplasm, and has been recently exploited as an enhancer of transgene expression. The retention of mutant myotonic dystrophy protein kinase (DMPK) transcripts in the nucleus of myotonic dystrophy (DM) cells has an important pathogenic role in the disease, resulting in pleiotropic ...
متن کاملConserved CPEs in the p53 3' untranslated region influence mRNA stability and protein synthesis.
BACKGROUND The 3' untranslated region (UTR) of p53 mRNA contains two conserved U-rich sequences resembling cytoplasmic polyadenylation elements (CPE). It is not known if these sequences regulate p53 expression by post-transcriptional mechanisms. MATERIALS AND METHODS Stable p53 3'UTR reporter HaCaT skin and MCF-7 breast cancer cell lines were established. Quantitative PCR and an enzymatic ass...
