Project description:The differentiation of naïve CD4+ T cells into T helper (Th) subsets is key for a functional immune response and has to be tightly controlled by transcriptional and epigenetic processes. However, the function of cofactors that connect gene-specific transcription factors with repressive chromatin-modifying enzymes in Th cells is yet unknown. Here we identified genome-wide binding sites of the cofactor NCOR1 in naive CD4+ T cells by using ChIP-seq.

Project description:Analysis of Treg cells isolated from WT and NCOR1-cKO mice indicated an important function of NCOR1 in regulating the transition from naïve to effector Treg cells. The aim of this NGS experiment was to determine the transcriptome profile of ex vivo isolated naïve and effector WT and NCOR1-cKO Treg cells under steady state condition.

Project description:We found in our study that NCoR1 knock down dendritic cells (DCs) develop tolerogenic behavior upon activation and these cells have the potential to modulate T helper cell differentiation toward Treg phenotype. Here to understand the mechanism of this process we performed NCoR1 ChIP-seq in wild type DCs before and after CpG ligand activation and transcriptome analysis of NCoR1 KD DCs to identify the direct and indirect target genes. We also predicted PU.1 as the recruting factor for NCoR1 in DCs based on motif enrichment and later on validated that by performing PU.1 ChIP-seq in control and NCoR1 KD DCs.

Project description:Corepressors negatively regulate gene expression by chromatin compaction. Targeted regulation of gene expression could provide a means to control endothelial cell phenotype. We hypothesize that by targeting corepressor proteins, endothelial angiogenic function can be improved. To study this, the expression and function of nuclear corepressors in human umbilical vein endothelial cells (HUVEC) and in murine organ culture was studied. RNA-seq revealed that nuclear receptor corepressor 1 (NCoR1), Silencing Mediator of Retinoid and Thyroid hormone receptors (SMRT) and repressor element-1 silencing transcription factor (REST) are the highest expressed corepressors in HUVECs. Knockout and knockdown strategies demonstrated that the depletion of NCoR1 increased the angiogenic capacity of endothelial cells, whereas depletion of SMRT or REST did not. Interestingly, the effect was VEGF signaling independent. NCoR1 depletion significantly upregulated angiogenesis-associated genes, especially tip cell genes, including ESM1, DLL4 and NOTCH4, as observed by RNA- and ATAC-seq. Confrontation assays comparing cells with and without NCoR1-deficiency revealed that loss of NCoR1 promotes a tip-cell position during spheroid sprouting. Moreover, a proximity ligation assay identified NCoR1 as a direct binding partner of the Notch-signaling-related transcription factor RBPJk. Luciferase assays showed that siRNA-mediated knockdown of NCoR1 promotes RBPJk activity. Furthermore, NCoR1 downregulation prompts upregulation of several elements in the Notch signaling cascade. Downregulation of NOTCH4, but not NOTCH1, prevented the positive effect of NCoR1 knockdown on spheroid outgrowth. Collectively, these data indicate that decreasing NCOR1 expression is an attractive approach to promote angiogenic function.

Project description:NCOR1 is a trancriptional coregulator and has been demonstrated to modulate the acitivities of multiple transcription factors in many cell types. However, the function of NCOR1 in vascular smooth muscle cells (VSMCs) is unclear. We aimed to explore the effect of NCOR1 deficiency on gene expression in VSMCs and phenoypic modulation of VSMCs. Therefore, we constructed smooth-muscle specific NCOR1 knockout mice and isolated primary VSMCs for RNA-sequencing.

Project description:NCoR1 (Nuclear receptor Co-Repressor) and SMRT (Silencing Mediator of Retinoid and Thyroid hormone receptor) are well-recognized coregulators of nuclear receptor (NR) action. However, their unique roles in the regulation of thyroid hormone (TH) signaling in specific cell types have not been determined. To accomplish this we generated a mouse model that lacked function of either NCoR1 or SMRT or both in the liver only. Despite both corepressors being present in the liver, SMRT had no ability to regulate TH signaling when deleted in either euthyroid or hypothyroid animals. In contrast, disruption of NCoR1 action confirmed that it is the principal mediator of TH sensitivity in vivo. While SMRT played little role in TH signaling alone, when disrupted in combination with NCoR1 it greatly accentuated the activation of hepatic lipogenesis regulated by NCoR1. Thus, corepressor specificity exists in vivo and NCoR1 is the principal regulator of TH action in the liver. However, both NCoR1 and SMRT collaborate to control hepatic lipogenesis and lipid storage, which likely reflects their cooperative activity in regulating the action of multiple NRs including the thyroid hormone receptor (TR). RNA was extracted from livers from 3 individual mice for each group (Double-floxed, Liver specific-SMRT knock out, and Liver specific-double knock out); all were euthyroid, female mice
