Pmpcb,全称为Processing of mitochondrial precursor proteins c, beta subunit,编码一个线粒体前体蛋白加工酶的β亚基,参与线粒体蛋白质的成熟过程。该基因的突变与多种疾病相关,包括Leigh综合征、肝细胞癌、多系统线粒体功能障碍综合征等。Pmpcb基因的突变可能导致蛋白质加工酶活性降低,影响线粒体蛋白质的成熟和功能,进而引发线粒体功能障碍。

Leigh综合征是一种罕见的线粒体疾病,表现为发育倒退、基底神经节病变、共济失调等症状。Matthews等人报道了一名39岁的个体,其Pmpcb基因出现了一个新的剪接位点变异,导致第12个外显子的跳跃,并出现了Leigh综合征的症状[1]。Zheng等人发现,沉默Pmpcb基因可以增强肝癌细胞对索拉非尼治疗的敏感性,降低肿瘤负担并改善肿瘤荷瘤小鼠的存活率[2]。Liu等人利用生物信息学分析,发现Pmpcb基因是抑郁症诊断的生物标志物之一,并与其免疫浸润相关[3]。Takai等人发现,Pmpcb基因在EpCAM+肝细胞癌中具有治疗敏感性,可以抑制肿瘤生长和Wnt/β-catenin信号通路[4]。Luo等人发现,美国人参提取物和人参皂苷Rg3可以调节HCT-116人结直肠癌细胞中Pmpcb基因的表达[5]。Audet等人利用多组学技术,在8名未经分子诊断的共济失调患者中发现Pmpcb基因的变异[6]。Zhan等人报道了2名中国患者中的新型IBA57基因突变,并回顾了多系统线粒体功能障碍综合征的临床、遗传和治疗进展[7]。Kistol等人报道了俄罗斯Leigh综合征患者的临床和分子特征,发现Pmpcb基因的变异是Leigh综合征的常见原因之一[8]。Luczynski等人发现,急性淋巴细胞白血病细胞来源的树突状细胞表达肿瘤相关抗原,包括Pmpcb基因[9]。Tai等人发现,父母环境铜暴露会影响后代发育,其中Pmpcb基因的甲基化修饰和转录表达发生改变[10]。

综上所述,Pmpcb基因在多种疾病中发挥重要作用,包括Leigh综合征、肝细胞癌、多系统线粒体功能障碍综合征等。Pmpcb基因的突变可能导致蛋白质加工酶活性降低,影响线粒体蛋白质的成熟和功能,进而引发线粒体功能障碍。因此,研究Pmpcb基因的功能和机制对于理解线粒体疾病的发病机制和开发新的治疗方法具有重要意义。
