项目摘要

NRs function by interacting with coregulators, including corepressors such as N-CoR and SMRT that interact with unliganded NRs, and corepressors such as RIP140 that interact with liganded NRs. The corepressors, in turn, recruit histone deacetylase (HDAC) to the NR-bound target genes. Here we propose to determine the role of coregulators in regulating gene expression in cells that are pathologically affected in metabolic disease, namely adipocytes and liver. Specifically, this project proposes the generation and validation of coregulator knockdown reagents in adipocytes and mouse liver, the determination of the extent and integration of corepressor regulation of gene expression in adipocytes, and determining the extent and integration of corepressor regulation of gene expression in mouse liver.

NR 通过与核心调节因子相互作用发挥作用，包括相互作用的核心抑制因子，例如 N-CoR 和 SMRT 与未配体的 NR 以及与配体的 NR 相互作用的辅阻遏物（如 RIP140）。辅阻遏物，反过来，将组蛋白脱乙酰酶 (HDAC) 募集至 NR 结合的靶基因。这里我们建议确定共调节因子在调节代谢受到病理影响的细胞基因表达中的作用疾病，即脂肪细胞和肝脏。具体来说，该项目建议生成和验证脂肪细胞和小鼠肝脏中的核心调节因子敲低试剂，其程度和程度的测定脂肪细胞中基因表达的辅阻遏物调节的整合，并确定其程度和小鼠肝脏中基因表达的辅阻遏物调节的整合。
