Project description:We have found that Coactivator-associated Arginine Methyltransferase 1 (Carm1) mutant mice have highly penetrant heart defects. These are similar to those found in Pax3 mutant mice and PAX3 is a target of CARM1-mediated methylation. We analyzed gene expression at mid-gestation in both mutant lines.

Project description:Previous studies reported that NEAT1 and its partner p54nrb are necessary for CARM1 to associate with paraspeckles and H3R26 methylation. There are also reports that CARM1 is essential for LincGET's role in guiding the ICM lineage in mouse embryos. We speculate that there may be a connection between CARM1 and lncRNA. In order to verify our guess, we conducted lncRNA-seq experiments against CARM1 control or siRNA in MDA-MB-231 cells to explore the lncRNA that may be regulated downstream of CARM1. Here, we showed that CARM1 and HIF1A co-upregulates the expression of MALAT1 in hypoxia pathway to promote carcinogenesis and metastasis in triple-negative breast cancer cells. These results indicate that there is a connection among CARM1, HIF1A and MALAT1 in triple-negative breast cancer.

Project description:The skeletal myogenic lineage in developing embryos is specified within the somites and requires members of the Paired box (Pax) family of transcription factors. In particular, Pax3 is the first member of this family expressed in the central region of the dermomyotome and it is necessary for specification, migration and survival of the myogenic progenitors that will form the muscles of the limbs, diaphragm and tongue. To investigate Pax3 molecular functions in the developing mesoderm, we generated doxycycline-inducible mouse embryonic stem (ES) cells expressing untagged and HaFlag-tagged-Pax3. These cell lines were used to unbiasedly identify its interacting partners by tandem affinity purification followed by mass spectrometry.

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.

Project description:Exposure to environmental teratogenic pollutant leads to severe birth defects. However, the biological events underlying these developmental abnormalities remain undefined. Here we report a molecular link between an environmental stress response pathway and key developmental genes during craniofacial development. In our study, we focused on the development of the facial prominences at E11.5. To do so, we compared the transcriptomes of mutant embryos (*Pax3Pax3-ERD/GFP *called DM in the microarray samples) to the one of control embryos (*Pax3GFP/+ *called GFP in the sample names). These are knock-in genetic models described in Bajard et al., 2006 and Relaix et al., 2005. In both of them a cassette coding for the GFP is replacing one allele of the Pax3 gene. The Pax3-ERD allele is a conditional one that drives the expression of the dominant negative form of Pax3 (Pax3-ERD) composed of the Pax3 DNA binding domain fused to the engrailed repressor domain (ERD) upon activation of a Cre recombinase. In this study, the Cre was driven by the zygote specific PGK enhancer. Strikingly, mutant mice with impaired Pax3/7 function display severe craniofacial defects. We show these are associated with an up-regulation of the signaling pathway mediated by the Aryl hydrocarbon Receptor (AhR), the receptor to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), revealing a genetic interaction between Pax3 and AhR signaling. Activation of AhR signaling in Pax3-deficient embryos drives facial mesenchymal cells out of the cell cycle through the up-regulation of p21 expression. Accordingly, inhibiting AhR activity rescues the cycling status of these cells and the facial closure of Pax3/7 mutants. Together, our findings demonstrate that the regulation of AhR signaling by Pax3/7 is required to protect against TCDD/AhR-mediated teratogenesis during craniofacial development.

Project description:CARM1 is essential for the development and maintenance of myeloid neoplasms. We found that non-phosphorylatable CARM1 mutation impairs cell cycle progression, induces apoptosis, and downregulates stemness in JAK2-mutant cell lines, suggesting that CARM1 phosphorylation is required for maximal proliferation of myeloid neoplasms.

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.

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.
