Various studies have shown that lysine acetyltransferase 2A (), E2F transcription factor 1 (), and ubiquitin conjugating enzyme E2 C () genes regulated the proliferation and migration of tumor cells through regulating the cell cycle. However, there is a lack of in-depth and systematic research on their mechanisms of action. This study analyzed The Cancer Genome Atlas (TCGA) to screen potential candidate genes and the regulation network of and complex in pan-cancer. Quantitative real-time PCR (qRT-PCR) and Western blotting (WB), cell phenotype detection, immunofluorescence co-localization, chromatin immunoprecipitation assay (ChIP), and RNA-Seq techniques were used to explore the functional of a candidate gene, . We found that the expression of these three genes was significantly higher in more than 10 tumor types compared to normal tissue. Moreover, was mainly expressed in tumor cells, which highlighted the impacts of as a specific therapeutic strategy. Moreover, and could promote cell proliferation and the migration of cancer cells by enhancing the expression of . Mechanically, was found to cooperate with and be recruited by to the promoter for elevating the expression of by increasing the acetylation level of H3K9.
多种研究表明,赖氨酸乙酰转移酶 2A ()、E2F 转录因子 1 () 和泛素连接酶 E2 C () 通过调节细胞周期来调控肿瘤细胞的增殖和迁移。然而,它们的作用机制缺乏深入和系统的研究。本研究通过分析癌症基因组图谱(TCGA)筛选出潜在的候选基因和泛癌中 和 复合物的调控网络。采用定量实时 PCR(qRT-PCR)和 Western blot(WB)、细胞表型检测、免疫荧光共定位、染色质免疫沉淀测定(ChIP)和 RNA-Seq 技术来探索候选基因 的功能。我们发现,与正常组织相比,这三个基因在 10 多种肿瘤类型中的表达明显更高。此外, 主要在肿瘤细胞中表达,这突出了 作为一种特定治疗策略的重要性。此外, 和 可以通过增强 的表达来促进癌细胞的增殖和迁移。从机制上讲,发现 与 合作,并被 招募到 启动子,通过增加 H3K9 的乙酰化水平来提高 的表达。
