Cancer&Entry Information
| Cancer Name | hepatocellular carcinoma |
| ICD-0-3 | C22.0 |
| Methods | qPCR, Western blot, Cell proliferation assay, Cell invasion assay etc. |
| Sample | HCC tissues, cell lines (L-02, HepG2, SNU423, SMMC-7721, Hep3B) |
| Expression Pattern | down-regulated |
| Function Description | In our study, the aberrant decreased level of MEG3 in 72 tumor tissues obtained from HCC patients and cell lines was examined by using real-time PCR. The inhibition affection in proliferation and inducing affection in apoptosis was further confirmed in vivo and vitro, we also demonstrated that MEG3 regulates HCC cell proliferation and apoptosis partially via the accumulation of p53. Besides, the hypermethylation of MEG3 in promoter region was identified by bisulfite sequencing while MEG3 increased with the inhibition of methylation. Down-regulation of UHRF1 induced MEG3 expression in HCC cell lines, which could be reversed by the up-regulation of UHRF1. In addition, up-regulation of MEG3 in HCC cells partially diminished the promotion of proliferation induced by UHRF1. |
