| Cancer Name | gastric cardia adenocarcinoma |
| ICD-0-3 | C16.0 M8140/3 |
| Methods | qPCR, Cell transfection, Cell proliferation assay etc. |
| Sample | GCA tissues, cell lines (MKN45, SGC7901, BGC823, and AGS) |
| Expression Pattern | down-regulated |
| Function Description | MEG3 and miR-770 was significantly downregulated in GCA patients and cell lines. Overexpression of MEG3 and miR-770 inhibited gastric cancer cell proliferation and invasion in vitro. Furthermore, the expression level of MEG3 and miR-770 was significantly increased in cancer cells after treated with 5-Aza-dC. The aberrant hypermethylation of proximal promoter and enhancer region of MEG3 was detected in GCA tissues. |
