CCAT2(Colon Cancer Associated Transcript 2)是一种长链非编码RNA(lncRNA),最初在结肠癌中被发现,但后续研究表明它在多种癌症和其他疾病中发挥重要作用。CCAT2位于人类8号染色体(8q24.21),靠近MYC癌基因,其表达受Wnt/β-catenin信号通路调控。CCAT2的主要功能包括调控细胞增殖、迁移、侵袭和凋亡,尤其在肿瘤发生发展中起关键作用。它通过多种机制发挥作用,例如作为竞争性内源RNA(ceRNA)吸附miRNA(如miR-145、miR-216b),从而解除这些miRNA对靶基因的抑制,促进癌基因表达。此外,CCAT2还能与转录因子(如TCF7L2)相互作用,增强Wnt信号通路活性,进一步驱动肿瘤进展。CCAT2的突变或异常表达与多种癌症相关,包括结直肠癌、胃癌、乳腺癌和肺癌等。过表达CCAT2通常与肿瘤恶性程度高、预后差相关,而降低其表达可抑制肿瘤生长和转移。CCAT2还影响化疗耐药性,例如在结直肠癌中,高表达CCAT2会导致对5-氟尿嘧啶的耐药性增强。CCAT2属于癌症相关长链非编码RNA家族,这类RNA通常不编码蛋白质,但通过调控基因表达、染色质修饰或信号通路参与癌症进程。该家族的共性包括在多种癌症中异常表达、通过ceRNA机制调控miRNA功能、影响关键信号通路(如Wnt、PI3K/AKT)以及与肿瘤干细胞特性相关。除癌症外,CCAT2的异常表达还可能参与炎症反应和心血管疾病。例如,在动脉粥样硬化中,CCAT2通过调控血管平滑肌细胞增殖加剧病变。由于CCAT2在疾病中的重要作用,它被认为是潜在的诊断标志物和治疗靶点。针对CCAT2的反义寡核苷酸或siRNA策略正在研究中,可能为癌症治疗提供新方向。
