Thoc1(也称为p84或Hpr1)是一种编码哺乳动物TREX复合体中一个必需蛋白亚基的基因。TREX复合体是一个进化上保守的复合物,它在转录过程中与RNA聚合酶II相互作用,促进RNA的加工和核输出。Thoc1的缺失会导致转录延伸和某些RNA的核输出的受损,影响基因表达和细胞功能。Thoc1在哺乳动物早期胚胎发育中起着至关重要的作用,Thoc1基因的纯合子缺失会导致胚胎在植入前死亡[7]。

Thoc1在多种癌症中发挥着重要作用。在胰腺腺癌中,Thoc1与p53基因联合治疗比单独使用p53基因治疗更有效,能够更有效地抑制肿瘤生长[1]。Thoc1的缺失会损害小鼠睾丸的正常发育,导致精子发生严重受损和雄性不育[2]。Thoc1的缺失还会影响小鼠的胚胎发育和成体组织的稳态,导致胚胎死亡和成体组织的功能异常[3]。Thoc1在前列腺癌的进展中起着重要作用,Thoc1的缺失可以阻止前列腺癌的进展[4]。Thoc1的过表达与结直肠癌的侵袭性表型和不良预后相关[8]。Thoc1的缺失会导致小鼠骨髓中的粒细胞-巨噬细胞祖细胞生长和存活受损[5]。Thoc1的缺失还会导致小鼠晚发性非综合征性听力丧失,这是通过p53介导的毛细胞凋亡实现的[6]。

Thoc1是一种重要的RNA结合蛋白,参与调控RNA的加工和核输出,影响基因表达和细胞功能。Thoc1在多种癌症中发挥着重要作用,包括胰腺腺癌、前列腺癌和结直肠癌。Thoc1的缺失会导致小鼠胚胎发育、睾丸发育和骨髓稳态的异常,并导致晚发性非综合征性听力丧失。Thoc1的研究有助于深入理解RNA加工和核输出的生物学功能和疾病发生机制,为疾病的治疗和预防提供新的思路和策略。
