Cancer&Entry Information
| Cancer Name | hepatocellular carcinoma |
| ICD-0-3 | C22.0 |
| Methods | qPCR, Western blot, Luciferase reporter assay |
| Sample | The HepG2 HCC cell line, HCC Cancer and carcinoma-adjacent tissue, HCC Cancer and carcinoma-adjacent tissue |
| Expression Pattern | down-regulated |
| Function Description | MEG3 expression was downregulated in cancer regions of HCC samples; by contrast, miRNA-10a-5p was overexpressed in cancer regions compared to tumor-adjacent areas. Furthermore, overexpression of MEG3 (a) decreased proliferation, migration, and invasion of HepG2 cells; (b) enhanced apoptosis and the proportion of HepG2 cells in G1 of the cell cycle; (c) increased the expression of phosphatase and tensin homolog (PTEN), Bcl2- associated X (Bax), and p53 proteins; and (d) decreased the expression of miRNA-10a-5p, AKT, p-AKT, Bcl-2, and the matrix metalloproteinases (MMPs)-2 and -9. Furthermore, miRNA-10a-5p bound the 3-untranslated region of PTEN mRNA and downregulated PTEN protein expression. |
