基因信息
human ... PROM1(8842)
一般描述
Prominin-1（UniProt：O43490；也称为抗原AC133，Prominin样蛋白质1，CD133）由人的PROM1（也称为PROML1，MSTP061）基因（基因ID：8842）编码。CD133（Prominin-1）是多通道细胞表面糖蛋白，在细胞分化、增殖和凋亡中起作用。它结合含胆固醇的质膜微区中的胆固醇，并可能在上皮细胞的顶质膜的组织中起作用。在视网膜早期发育过程中，CD133充当盘形态发生的关键调节因子。已知PROM1基因缺陷会导致色素性视网膜炎、视锥杆细胞营养不良和视网膜黄斑营养不良2。已经报道了几种癌细胞类型中较高水平的CD133，包括各种白血病、视网膜母细胞瘤、胶质母细胞瘤和肾癌。在胰腺癌、胃癌、结直肠癌和肝细胞癌中也观察到更高水平的CD133。它也被认为是成年小肠中干细胞的标志物，这些干细胞易于转化为保留一部分突变Prom1+肿瘤细胞的肿瘤。（参考文献：Zhu, L., et al. (2009).Nature 477（7229）；603-607）。

Cancer stem cells (CSCs) are major contributors to the malignant transformation of cells because of their capacity for self-renewal. Aldehyde dehydrogenase1A1 (ALDH1A1) and CD133 are promising candidate of CSC markers in non-small cell lung cancer (NSCLC). Furthermore, TP53 is frequently

Insufficient radiofrequency ablation (iRFA) often leads to residual hepatocellular carcinoma (HCC) progression. However, the mechanism is still poorly understood. In the present study, we demonstrated that LC3B protein expression levels were significantly increased in the residual hepatocellular carcinoma cells after
