H3K18乳酰化通过转录与翻译后修饰抑制CD248,促进髓核细胞凋亡与细胞外基质降解

H3K18 Lactylation in Degenerated Nucleus Pulposus Cells Suppresses CD248 Through Transcriptional and Post‐Translational Modifications to Promote Apoptosis and Extracellular Matrix Degradation

AI 导读

退变椎间盘髓核细胞中乳酸与乳酰化水平升高,H3K18la 通过招募 SMARCA5 共富集于 CD248 启动子抑制其 mRNA 表达,并经泛素—蛋白酶体途径促进 CD248 蛋白降解。CD248 的双重抑制激活 Hedgehog 通路,诱导髓核细胞凋亡与细胞外基质降解,研究由此提出乳酸–H3K18la–CD248 调控轴(Aging Cell,体外细胞实验)。
