Histone arginine methyltransferase CARM1 Is Crucial for Epigenetic Regulation of Starvation-induced Autophagy

ABSTRACT: Autophagy is a highly conserved self-digestion process, essential to maintain homeostasis and viability in response to nutrient starvation. Although the components of autophagy in the cytoplasm have been well-studied, molecular basis for the epigenetic regulation of autophagy is poorly understood. Here, we identify histone arginine methyltransferase CARM1 as a critical component of autophagy. We found that nutrient starvation increased CARM1 protein level and subsequently histone H3R17 dimethylation. Genome-wide analyses reveal that CARM1 exerts transcriptional coactivator function on autophagy-related genes and lysosomal genes through TFEB. Our findings demonstrate a previously unrecognized role of CARM1-dependent histone arginine methylation as a critical nuclear event of autophagy.

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.

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.
