Project description:Histone dimethyl transferase WHSC1 drives the transcription of MHC-I machinery in mouse and human colorectal cancer cells (CRCs); thus, WHSC1 downregulation potentiates CRCs to escape from cytotoxic CD8+ T cell responses. WHSC1 directly interacts with MHC-I transactivator, NLRC5 to selectively stimulate MHC-I gene expression. Thus, silencing Whsc1 diminished MHC-I level, impaired anti-tumor immunity and blunted immunotherapy efficacy.
Project description:Whsc1 gene codes for a SET domain-containing H3K36 dimethylase, whose activity has been suggested, in ex vivo cell culture experiments, to control many aspects of DNA and RNA processing (replication, repair, transcription, etc). Its precise function in vivo is still unclear. Here, we use RNA-seq transcriptome analysis to study the changes in gene expression in the absence of Whsc1. Our results show that, in the experimental system used, loss of Whsc1 caused massive changes in genes affecting many fundamental cellular processes, from cell cycle to ribosome synthesis, DNA repair, replication, etc.

Its precise function in vivo is still unclear. Here, we use RNA-seq transcriptome analysis to study the changes in gene expression in the absence of Whsc1 in sorted Bone Marrow proB cells. Our results show that, in the experimental system used, loss of Whsc1 caused massive changes in genes affecting many fundamental cellular processes and also severly interefering with B cell fate specification and commitment
Project description:We report here chromatin related factor Whsc1 links pluripotency exit and mesendodermal differentiation. We performed RNA-seqs to compare Whsc1+/+ and Whsc1-/- embryonic stem cells (ESCs) to compare the transcriptomes. UMI-4C experiments have been performed to identify regions having contacts with promoter regions of downstream Whsc1 targets: the mesendoderm transcritpion factors
Project description:By comparing the small intestine transcriptomes of 4 wild type and 3 ASE-/- mice, we identified several oxidative balance related genes are exressed differentially between WT and ASE-/- in postnatal day 1.5 small intestine when dietary nutrient uptake became vital to support neonatal physiology. We here discover that the asymmetry enhancer of Pitx2 is critical for proper redox homeostasis.This is in agreement with the previous discovery that Pitx2 is important for cellular oxidative balance and is therefore important in cellular maturation and differentiation.
