Neoplasms contain tumor-initiating stem-like cells (TICs) that are characterized by increased drug resistance. The incidence of many cancer types have trended downward except for few cancer types, including hepatocellular carcinoma (HCC). Therefore mechanism of HCC development and therapy resistance needs to be understood. These multiple hits by hepatitis C virus (HCV) eventually promotes transformation and TIC genesis, leading to HCC development. This review article describes links between HCV-associated HCC and TICs. This review discusses 1) how HCV promotes genesis of TICs and HCC development; 2) how this process avails itself as a novel therapeutic target for HCC treatment; and 3) ten hall marks of TIC oncogenesis and HCC development as targets for novel therapeutic modalities.
肿瘤包含具有肿瘤起始能力的干细胞样细胞(TICs),其特征是耐药性增强。除了少数几种癌症类型(包括肝细胞癌(HCC))外,许多癌症类型的发病率都呈下降趋势。因此,需要了解HCC的发生发展机制以及治疗耐药性。丙型肝炎病毒(HCV)的这些多重打击最终促进了细胞转化和TIC的产生,导致HCC的发展。这篇综述文章描述了HCV相关HCC与TICs之间的联系。本综述讨论了:1)HCV如何促进TICs的产生和HCC的发展;2)这一过程如何成为HCC治疗的新靶点;3)作为新型治疗方式靶点的TIC肿瘤发生和HCC发展的十大特征。
