Abstract

T-box转录因子(T-box transcription factor gene, TBX)基因涉及器官的发生,TBX5在人的正常心脏和肺组织中表达水平最高。TBX5的缺乏可能导致胸廓发育畸形和膈肌发育异常,其异位表达和过表达会诱导细胞凋亡和抑制细胞生长。既往研究发现了TBX5在食管腺癌、胃癌、结肠癌和乳腺癌的发生和发展中的潜在作用。我们对TBX2亚家族的基因表达和预后之间的关系进行了综述,同时探究TBX5在调控肺癌发生发展机制中的研究进展。虽然TBX5和肺癌发生之间的关系尚不明确,不过TBX5可以显著抑制人体内肿瘤生长,其表达水平和肺癌的进展呈现负相关。由此,TBX5的基因表达水平和甲基化程度是潜在的表证肺癌增殖和转移的生物标志物,具有作为肺癌治疗靶点的潜力。
