title: ZNF143 is regulated through alternative 3'UTR isoforms.
abstract: ZNF143 is a ubiquitously expressed transcription factor conserved in all vertebrates, regulating genes involved in primary metabolism and cell growth. It is therefore crucial to tightly maintain the adequate level of this factor in the cell. Although ZNF143 expression is auto-regulated at the transcriptional level, nothing is known about the post-transcriptional events influencing its expression. In this work, performed in mammalian cells, we show that ZNF143 expresses different 3'-untranslated regions (3'-UTR) as a result of alternative polyadenylation. These 3'UTR isoforms have a diverse impact on the ZNF143 transcript fate. Indeed, we show that the longest isoform, unlike the short one, contains a destabilizing AU-Rich element and is targeted by the miRNA 590-3p. Additionally we observed a correlation between ZNF143 downregulation and miR-590-3p up-regulation in retinoic acid treated teratocarcinoma cells. This strongly suggests that ZNF143 post-transcriptional regulation depends on the long 3'UTR isoform during teratocarcinoma cells differentiation. Finally we evidenced that the alternative polyadenylation site usage is independent of the previously identified ZNF143 transcriptional auto-regulation.
