Popis: | BACKGROUND The expression and significance of small nucleolar RNA host gene 7 (SNHG7) in early-stage colon carcinogenesis remains unclear. METHODS The level of SNHG7 and microRNA-193b (miR-193b) was detected by qRT-PCR in colon tumor tissues and cells. The interaction of SNHG7 and miR-193b and the influence of SNHG7 silencing on colon tumor cells was evaluated. RESULTS Stepwise upregulated SNHG7 in colon advanced adenomas and early-stage cancer negatively correlates with miR-193b level, the direct interaction was confirmed in vitro. SNHG7 silencing in HT29 cells decreased proliferation and promoted apoptosis by inhibiting K-ras/ERK/cyclinD1. CONCLUSIONS SNHG7 is an oncogenic biomarker in colon carcinogenesis. The effect may be mediated by interaction with miR-193b. |
