DCST1,也称为DC-STAMP domain containing 1,是一种进化上保守的精子因子,在哺乳动物中对于精卵融合至关重要。DCST1蛋白含有七个跨膜结构域,其在精子中表达,并通过与卵细胞表面的JUNO(IZUMO1R)受体结合来触发精卵融合。DCST1的缺失会导致精子不能与卵子结合,从而引起不育[4]。

除了在生殖过程中的作用,DCST1的基因和蛋白在癌症研究中也受到了关注。DCST1的基因存在一个反义长链非编码RNA(lncRNA)DCST1-AS1,其在多种癌症中表现出异常表达。DCST1-AS1在胶质母细胞瘤(GBM)中高表达,并与患者的较差生存率相关。研究发现,DCST1-AS1通过甲基化下调miR-29b的表达,从而促进GBM细胞的增殖[1]。在肝细胞癌(HCC)中,DCST1-AS1的高表达也与较大的肿瘤和较短的生存时间相关。DCST1-AS1作为竞争性内源RNA,通过结合miR-1254来上调Fas凋亡抑制因子2(FAIM2)的表达,最终促进HCC细胞的增殖[2]。在结直肠癌(CRC)中,DCST1-AS1的表达上调与患者的较差预后相关。DCST1-AS1通过hsa-miR-582-5p/高迁移率族蛋白B1(HMGB1)轴调节CRC细胞的侵袭性,包括细胞增殖、集落形成、迁移和侵袭[3]。此外,DCST1-AS1在口腔鳞状细胞癌(OSCC)中通过促进M2巨噬细胞极化并通过激活NF-κB信号通路来促进OSCC的发生[5]。在宫颈癌中,DCST1-AS1的表达上调,通过增加miR-874-3p的表达来抑制宫颈癌细胞的增殖、迁移和侵袭[6]。在HCC中,DCST1-AS1的表达上调,通过AKT/mTOR信号通路促进HCC细胞的增殖、迁移和侵袭,并抑制细胞凋亡和自噬[7]。在TNBC中,DCST1-AS1的表达上调,通过形成与miR-873-5p和MYC的正反馈调节环来促进TNBC细胞的增殖和转移[9]。此外,DCST1-AS1在胆囊癌中也表现出异常表达,并可能与细菌和病毒基因组之间存在水平基因转移[8]。

综上所述,DCST1及其lncRNA DCST1-AS1在生殖和癌症中发挥着重要作用。DCST1在精卵融合中起着关键作用,而DCST1-AS1在多种癌症中表现出异常表达,并与患者的预后相关。DCST1-AS1通过调节miRNA的表达和信号通路来影响癌症的发生和发展。此外,DCST1-AS1在胆囊癌中也表现出异常表达,并可能与细菌和病毒基因组之间存在水平基因转移。因此,深入研究DCST1及其lncRNA DCST1-AS1的功能和机制对于理解生殖和癌症的发生和发展具有重要意义,并为疾病的治疗和预防提供新的思路和策略。
