ZNF827-dependent splicing dynamics are critical for EMT during development and disease [RNA-seq]

Project description:Epithelial to mesenchymal transition (EMT) is a multi-step process during which epithelial cells become mesenchymal stem cells. EMT is involved during embryonic development, wound healing, fibrosis and tumor metastasis. Here we show that ZNF827, a C2H2-zinc finger containing protein, is critical for molecular and phenotypic changes underlying EMT. We demonstrate that ZNF827 depletion suppresses tumor metastasis and cortical neurogenesis in vivo by impairing EMT. Further analysis showed that ZNF827 is critical for global alternative splicing (AS) during EMT. We further reveal that ZNF827 interacts with various components of core splicing machinery and directly binds DNA. ZNF827 depletion leads to alteration of epigenetic landscape at its target genomic region which might be important for alternative splicing of these target genes. Our findings established ZNF827 as a novel regulator of AS during development and disease contexts of EMT.

Transcription and splicing dynamics during early <i>Drosophila</i> development.

Project description:Widespread cotranscriptional splicing has been demonstrated from yeast to human. However, most studies to date addressing the kinetics of splicing relative to transcription used either Saccharomyces cerevisiae or metazoan cultured cell lines. Here, we adapted native elongating transcript sequencing technology (NET-seq) to measure cotranscriptional splicing dynamics during the early developmental stages of Drosophila melanogaster embryos. Our results reveal the position of RNA polymerase II (Pol II) when both canonical and recursive splicing occur. We found heterogeneity in splicing dynamics, with some RNAs spliced immediately after intron transcription, whereas for other transcripts no splicing was observed over the first 100 nt of the downstream exon. Introns that show splicing completion before Pol II has reached the end of the downstream exon are necessarily intron-defined. We studied the splicing dynamics of both nascent pre-mRNAs transcribed in the early embryo, which have few and short introns, as well as pre-mRNAs transcribed later in embryonic development, which contain multiple long introns. As expected, we found a relationship between the proportion of spliced reads and intron size. However, intron definition was observed at all intron sizes. We further observed that genes transcribed in the early embryo tend to be isolated in the genome whereas genes transcribed later are often overlapped by a neighboring convergent gene. In isolated genes, transcription termination occurred soon after the polyadenylation site, while in overlapped genes, Pol II persisted associated with the DNA template after cleavage and polyadenylation of the nascent transcript. Taken together, our data unravel novel dynamic features of Pol II transcription and splicing in the developing Drosophila embryo.
