摘要
Sox9基因作为一个重要转录因子,在软骨形成中起着极其重要的调控作用,相关研究对软骨缺损修复等组织再生工程发展具有十分重要的意义。软骨形成过程中软骨细胞增殖、分化调控过程复杂,参与的细胞因子较多,目前比较明确的是Sox9结合于软骨细胞特异增强子Col2α1,直接调控其表达。L-Sox5、Sox6与Sox9共同形成蛋白复合物协同作用于Col2α1增强子序列,增强其转录,并通过结合于PTHrP基因的启动子区上调PTHrP基因启动子活性,刺激软骨细胞早期阶段增殖和发育。Sox9与Wnt/β-catenin和TGF-β/Smad信号转导通路相互作用,调控软骨细胞分化。最新研究显示,Sox9基因在软骨形成过程中还与其他物理因子和生物因子如低氧、电磁场等相互影响、相互作用。
