The removal of mRNA transcript poly(A) tails by 3'-5' exonucleases is the rate-limiting step for controlled mRNA decay in eukaryotes. Poly(A)-specific ribonuclease (PARN) is one such exonuclease that degrades poly(A) tails, and although its in vitro activity is well-characterized, PARN’s patho-physiological roles in the cell are not well understood. Prior studies have found a possible role for PARN in cancer, in that PARN expression levels in human breast cancer tissues are often decreased compared to normal control tissues. Indeed, data mined from the ONCOMINE cancer array database showed that PARN is downregulated in patient invasive breast carcinoma samples compared to …

DNp63a, a member of the p53 family of transcription factors, is overexpressed in a number of cancers and known to play a role in proliferation, differentiation, migration and invasion. DNp63a has been shown to regulate several microRNAs that play a role in both development and cancer, but to date there has not been a global analysis of p63- regulated miRNA. Using next-generation sequencing of small RNA from wild type and sip63 transfected HaCaT cells, our laboratory recently identified a number of DNp63a- regulated miRNAs by RNA-Seq studies which may serve as biomarkers of cancer progression. We identified a novel miRNA, …
