SLC35B3,也称为PAPS转运蛋白2(PAPST2),是一种重要的蛋白质,负责在Golgi体上转运3'-磷酸腺苷5'-磷酸硫酸盐(PAPS)。PAPS是一种高能量的硫酸供体,对于多种分子的硫酸化修饰至关重要。硫酸化是一种重要的翻译后修饰,它调节了许多生物过程,包括细胞信号传导、蛋白质稳定性和细胞黏附。SLC35B3在细胞内PAPS的分配和维持中发挥着关键作用,从而影响细胞内的硫酸化状态[6][7]。
SLC35B3的异常表达和功能改变与多种疾病的发生和发展相关。在结直肠癌中,SLC35B3的表达水平升高,并且其功能改变与肿瘤细胞的增殖和转移相关[6]。此外,SLC35B3的基因变异与结直肠癌的发生风险相关[2]。在卵巢癌中,SLC35B3的表达水平与化疗反应相关,可以作为预测化疗效果的生物标志物[4]。在膀胱癌中,SLC35B3的表达水平与对顺铂化疗的反应相关,可以作为预测化疗效果的生物标志物[3]。SLC35B3的异常表达和功能改变还与炎症性肠病的发生和发展相关。一项研究发现,高脂肪饮食会导致肠道内吲哚-3-乙酸(IAA)水平降低,从而影响肠道黏膜的硫酸化,进而导致肠道屏障损伤和炎症性肠病的发生。补充IAA可以增强肠道黏膜的硫酸化,并有效缓解炎症性肠病[1]。此外,SLC35B3的基因变异还与2型糖尿病的发生风险相关[5]。
SLC35B3的研究有助于深入理解细胞内硫酸化状态的调节机制,以及其与多种疾病发生和发展之间的关系。SLC35B3可以作为预测疾病风险和治疗反应的生物标志物,为疾病的治疗和预防提供新的思路和策略。
