REST corepressors (s) are the core component of the LSD1/CoREST/HDACs transcriptional repressor complex, which have been revealed differently expressed in various cancers, but the therapeutic and prognostic mechanisms in cancer are still poorly understood. In this study, we analyzed expression, prognostic value, molecular subtypes, genetic alteration, immunotherapy response and drug sensitivity of s in pan-cancer. Clinical correlation, stemness index, immune infiltration and regulatory networks of s in hepatocellular carcinoma (HCC) were detected through TCGA and GSCA database. experiments were conducted to explore the role of RCOR1 in HCC cells. The expression of s varied among different cancers, and have prognostic values in several cancers. Cancer subtypes were categorized according to the expression of s with clinical information. s were significantly correlated with immunotherapy response, MSI, drug sensitivity and genetic alteration in pan-cancer. In HCC, s were considered as potential predictor of stemness and also had association with immune infiltration. The ceRNA-TF-kinase regulatory networks of s were constructed. Besides, RCOR1 acts as an oncogene in HCC and promotes the proliferation of HCC cells by inhibiting cell cycle arrest and cell apoptosis. Taken together, our study revealed the potential molecular mechanisms of s in pan-cancer, offering a benchmark for disease-related research.
REST共抑制因子是LSD1/CoREST/HDACs转录抑制复合物的核心组成部分,已发现在各种癌症中表达不同,但癌症中的治疗和预后机制仍知之甚少。在本研究中,我们分析了泛癌中REST共抑制因子的表达、预后价值、分子亚型、基因改变、免疫治疗反应和药物敏感性。通过TCGA和GSCA数据库检测了肝细胞癌(HCC)中REST共抑制因子的临床相关性、干性指数、免疫浸润和调控网络。进行实验以探索RCOR1在肝癌细胞中的作用。REST共抑制因子的表达在不同癌症中有所不同,并且在几种癌症中具有预后价值。根据REST共抑制因子的表达和临床信息对癌症亚型进行分类。REST共抑制因子在泛癌中与免疫治疗反应、微卫星不稳定性(MSI)、药物敏感性和基因改变显著相关。在肝癌中,REST共抑制因子被认为是干性的潜在预测指标,并且还与免疫浸润有关。构建了REST共抑制因子的ceRNA-转录因子-激酶调控网络。此外,RCOR1在肝癌中作为癌基因发挥作用,通过抑制细胞周期停滞和细胞凋亡促进肝癌细胞的增殖。综上所述,我们的研究揭示了泛癌中REST共抑制因子的潜在分子机制,为疾病相关研究提供了一个基准。
