Esophageal squamous cell carcinoma (ESCC) is the most prevalent type of esophageal cancer and accumulating evidence has confirmed the role of miRNAs in ESCC. One such miRNA, miR-370, was found to be aberrantly downregulated in various human malignancies. This study showed that the expression of miR-370 was significantly lower in ESCC tissues and cell lines, and miR-370 functioned as a tumor suppressor in ESCC. Moreover, this is the first report that showed miR-370 suppresses cell proliferation and tumor growth by directly targeting Pim family kinases 1 (PIM1). Furthermore, alpinumisoflavone, a naturally occurring flavonoid, could inhibit tumor growth of ESCC by targeting miR-370/PIM1 signaling.
食管鳞状细胞癌(ESCC)是食管癌最常见的类型,越来越多的证据证实了微小RNA(miRNA)在ESCC中的作用。其中一种miRNA,即miR-370,被发现在各种人类恶性肿瘤中异常下调。本研究表明,miR-370在ESCC组织和细胞系中的表达显著降低,且miR-370在ESCC中发挥肿瘤抑制作用。此外,这是首次报道miR-370通过直接靶向Pim家族激酶1(PIM1)来抑制细胞增殖和肿瘤生长。此外,高山槐黄素,一种天然存在的黄酮类化合物,可通过靶向miR-370/PIM1信号通路抑制ESCC的肿瘤生长。
