TMEM166 is a novel programmed cell death-related molecule. In this report, we constructed a recombinant adenovirus 5-TMEM166 vector (Ad5-TMEM166) and evaluated its expression and anti-tumor activities in vitro and in vivo. Cell viability analysis revealed that the adenovirus-mediated increase of TMEM166 inhibited tumor cell growth in a dose- and time-dependent manner. This inhibitory effect was mediated by both autophagy (via inhibition of mTOR and activation of p70S6K) and apoptosis (via caspase-3 activation), both of which contributed to cell death and suppression of tumorigenicity. Our data indicated that Ad5-TMEM166 may be a novel gene therapy candidate for cancer.
TMEM166 是一种新型的程序性细胞死亡相关分子。在本报告中,我们构建了重组腺病毒 5-TMEM166 载体(Ad5-TMEM166),并在体外和体内评估了其表达和抗肿瘤活性。细胞活力分析表明,腺病毒介导的 TMEM166 增加以剂量和时间依赖的方式抑制肿瘤细胞生长。这种抑制作用是通过自噬(通过抑制 mTOR 和激活 p70S6K)和细胞凋亡(通过 caspase-3 激活)介导的,这两者都导致细胞死亡和抑制肿瘤发生。我们的数据表明,Ad5-TMEM166 可能是癌症的一种新型基因治疗候选物。
