Bulk RNAseq analysis of control and Carm1 KO CD8 T cells

ABSTRACT: The overall goal of this study was to understand the change in antigen-stimulated gene expression in CD8 T cells upon ablation of a transcriptional coactivator Carm1 by CRISPR-Cas9 method. Seven days following editing, OT-I CD8 T cells were co-cultured for 24 hours with B16F10-Ova tumor cells. RNA-seq analysis demonstrated changes in gene expression, including upregulation of 1,143 genes and downregulation of 1,199 genes in Carm1 KO compared to control T cells. Upregulated genes encoded chemokine receptors that mediate T cell recruitment into tumors (Cxcr3) and key genes required for maintenance of memory T cell populations (transcription factor genes Tcf7, Myb, Bcl6; surface receptor Cd27). Downregulated genes included those associated with terminal differentiation (Klrg1), inhibition of cytokine signaling (Socs1, Socs3) and T cell dysfunction within tumors (Egr2, Eomes).

Gene expression profiles of CARM1 overexpression in MCF7

Project description:The goal of this study is to identify ERalpha-target genes affected by overexpression of the histone arginine methyltransferase CARM1 in breast cancer cells. The roles of CARM1 in ERalpha+ breast cancer was not well characterized. Therefore, we created a Dox inducible CARM1 overexpressing MCF7 cell line where CARM1 is overexpressed by 2 fold to determine the created a Dox-inducible CARM1 overexpressing MCF7 cells for evaluation of the global effects of CARM1 on Eralpha-target gene expression. MCF7-tet-on-CARM1 clone 13 were treated under 4 conditions: DMSO; Dox; E2 (10nM); Dox+E2. In Dox+E2 condition, cells were pre-treated with Dox for 5 days before treating with E2 for 4 hours. 3 biological replicates were included and total of 12 samples were analyzed.

CARM1 substrate identification

Project description:The goal of the project was global identification of CARM1 substrates. Arginine methylation landscapes were profiled and compared in wild type and CARM1 knockout cells to determine in vivo substrates of CARM1.

Antigen-driven EGR2 expression is required for exhausted CD8+ T cell stability and maintenance [CHIP-seq]

Project description:In this study, we examined the role of the transcriptional regulator EGR2 in CD8+ T cell exhaustion during chronic viral infection. Flow cytometric and RNAseq analysis indicated that EGR2 deficient CD8+ T cells had a block in differentiation and failed to undergo terminal exhaustion. To examine the direct gene targets of EGR2 during exhaustion, we conducted ChIPseq analysis on enriched bulk splenic CD8+ T cells isolated at day 20 post-infection with chronic LCMV-Cl13 from C57BL/6J mice. The resulting data demonstrated that EGR2 directly controls expression of key gene targets, including Pdcd1, Tigit, Cxcr5, Tcf7, Bach2 and Bcl6.

Gene expression profiles of MCF7 with CARM1 knocked down

Project description:The goal of this study is to identify ERalpha-target genes affected by knocking down of the histone arginine methyltransferase CARM1 in MCF7 breast cancer cells. The roles of CARM1 in ERalpha+ breast cancer was not well characterized. Therefore, we created a Dox inducible CARM1 knockingdown MCF7 cell line where CARM1 is decreased to 20% of endogeneous level to determine the created a Dox-inducible CARM1shRNA overexpressing MCF7 cells for evaluation of the global effects of CARM1 on ERalpha-target gene expression. MCF7-tet-on-CARM1shRNA clone 1 were treated under 4 conditions: DMSO; Dox; E2 (10nM); Dox+E2. In Dox+E2 condition, cells were pre-treated with Dox for 5 days before treating with E2 for 4 hours. 3 biological replicates were included and total of 12 samples were analyzed.

Expression profiling of murine neonatal lung tissue from Carm1 knockouts and wild type controls

Project description:Coactivator associated arginine methyltransferase I (CARM1, also known as Protein aRginine MethylTransferase 4, or PRMT4) regulates gene expression by multiple mechanisms including methylation of histones and coactivation of steroid receptor transcription. Mice lacking CARM1 are smaller than their littermates, fail to breath, and die shortly after birth, demonstrating the critical role of CARM1 in development.We performed gene expression analysis to identify genes that are responsible for hyperproliferaion in CARM1 knockout lung. RNA extracted from murine lung at E18.5 with carm1 knockouts and wild type controls was hybridised to Affymetrix mouse430.2 GeneChips to identify differentially expressed genes in the disease state.

Global tibialis anterior skeletal muscle transcript data from male Carm1 skm-/- (HSAcre Tg/0 x Floxed Carm1) and Carm1 skm+/+ mice (HSAcre 0/0 x Floxed Carm1) on a chow diet.

Project description:Transcript data from tibialis anterior muscle from male muscle-specific Coactivator-Associated Arginine Methyltransferase 1 (Carm1 ) knockout mice (Carm1 skm-/- ) and wild-type mice (Carm1 skm+/+) generated by using the Cre-loxP system (on a C57BL6J/129 background) with HSA-Cre mice (from Jackson laboratories). We used RNA-Seq to detail the effects of muscle-specific loss of Carm1 on the global program of gene expression in tibialis anterior muscle.

CARM1 Methylates MED12 to Regulate its RNA Binding Ability

Project description:The coactivator-associated arginine methyltransferase (CARM1) functions as a regulator for transcription, splicing and chromatin regulation by methylating a diverse array of substrates. In this study, we used CARM1 substrate antibodies to perform immunoprecipitation coupled with mass spectrometry (IP-MS) in MEFs and identified Mediator Subunit 12 (MED12) as a novel substrate for CARM1. ChIP-seq analysis using CARM1, MED12 and H3R17me2a (represents ‘CARM1 activity’) antibodies revealed that MED12 targeted by CARM1 is recruited to the EREs (estrogen-responsive elements). Additionally, RT-PCR studies showed that the MED12R1899K mutation disrupting the methylation site reduced the expression of ER-target genes. Thus, MED12 methylation targets it to ER-specific enhancers and positively modulates transcription of Estrogen-driven genes.
