BACKGROUND/AIM: Hepatoma-derived growth factor (HDGF) is involved in the progression of hepatocellular carcinoma (HCC). The present study assessed the epigenomic changes in hepatoma-derived cells through HDGF stimulation.
We used two hepatoma-derived cell lines (HepG2 and SK-Hep1) and searched for microRNAs whose expression commonly changed in response to HDGF administration. We further explored a genetic database to investigate the association of the candidate microRNAs with the survival of HCC patients.
Despite both HepG2 and SK-Hep1 cells being categorized as hepatoma-derived cells, the microRNA profile differed between these two lines. However, HepG2 and SK-Hep1 cells shared 30 up-regulated and 2 down-regulated microRNAs. Of these, miR-6072 and miR-3137 were significantly associated with a poor prognosis in HCC patients.
We identified two candidate microRNAs whose expression increased in response to HDGF stimulation. Both these molecules were associated with a poor prognosis of HCC patients.
背景/目的:肝癌衍生生长因子(HDGF)参与肝细胞癌(HCC)的进展。本研究通过 HDGF 刺激评估肝癌衍生细胞的表观基因组变化。
我们使用两种肝癌衍生细胞系(HepG2 和 SK-Hep1),并寻找表达普遍因 HDGF 给药而改变的 microRNAs。我们进一步探索了一个遗传数据库,以研究候选 microRNAs 与 HCC 患者生存的关联。
尽管 HepG2 和 SK-Hep1 细胞均被归类为肝癌衍生细胞,但这两种细胞系之间的 microRNA 谱存在差异。然而,HepG2 和 SK-Hep1 细胞共有 30 个上调和 2 个下调的 microRNAs。其中,miR-6072 和 miR-3137 与 HCC 患者的不良预后显著相关。
我们鉴定了两种因 HDGF 刺激而表达增加的候选 microRNAs。这两种分子均与 HCC 患者的不良预后相关。
