RNA Sequencing Facilitates Quantitative Analysis of shL3MBTL2 ,CGA-OE and corresponding control Transcriptomes

ABSTRACT: L3MBTL2 is a crucial component of ncPRC1.6 and has been implicated in transcriptional repression and chromatin compaction. However, the repression mechanism of L3MBTL2 and its biological functions are largely undefined. CGA encodes the alpha subunit of glycoprotein hormones, however, we showed that CGA plays an individual tumor suppressor role in PDAC. The goals of this part study are to compare transcriptome profiling of PANC-1-shL3MBTL2 cells or PANC-1-CGA-OE cells to their corresponding control cells. By identifying differentially expressed genes (DEGs) and enrichment pathways, the mechanism of L3MBTL2 and CGA in pancreatic cancer can be better studied.

Project description:Human MBT domain‐containing protein L3MBTL2 was found to be an integral component of a protein complex that we termed Polycomb Repressive Complex 1‐like 3 (PRC1L3) given the presence of the PcG proteins RING1, RING2 and PCGF6. L3MBTL2 binds chromatin in a histone modification‐ independent manner and is required for the repressive function of PRC1L3. PRC1L3 also contains E2F6 and CBX3, two factors with well‐established functions in transcriptional repression. Genome‐wide profiling identified several hundred genes that are simultaneously bound by L3MBTL2 and E2F6, preferentially around transcriptional start sites. Importantly, these genes are largely distinct from those targeted by other E2Fs or L3MBTL, another MBT‐domain containing protein that interacts with RB1. H3K27 or H3K9 methylation, two chromatin modifications implicated in gene silencing, are not present on all L3MBTL2 target genes. L3MBTL2‐specific RNAi results in altered target gene expression patterns and affects the differentiation program of hematopoietic cells. Our data suggest that repression of transcription via chromatin modulation, reflective of PRC1 function, can be achieved by multiple players and does not necessarily require the presence of histone lysine methylation marks. 12 total ChIP-seq datasets; one E2F6 dataset and one Input dataset done from MCF7 cells on Nimblegen ENCODE arrays; one L3MBTL1 dataset and one Input dataset done from MCF7 cells on Nimblegen ENCODE arrays; one L3MBTL2 dataset and one Input dataset done from MCF7 cells on Nimblegen ENCODE arrays; one E2F6 dataset and one Input dataset done from MCF7 cells on Nimblegen 1.5kb promoter arrays; one L3MBTL1 dataset and one Input dataset done from MCF7 cells on Nimblegen 1.5kb promoter arrays; one L3MBTL2 dataset and one Input dataset done from MCF7 cells on Nimblegen 1.5kb promoter arrays.
