Cancer&Entry Information

Cancer Name	gallbladder cancer
ICD-0-3	C23.9
Methods	qPCR, Western blot etc.
Sample	GBC tissues, GBC cell lines (GBC-SD and QBC940)
Expression Pattern	down-regulated
Function Description	The effects of MEG3 and ANRIL were also verified in mice. Compared with normal tissues, the expression of MEG3 was significantly lower in GBC tissues, whereas the expression of ANRIL was significantly higher. The overexpression of MEG3 and underexpression of ANRIL were significantly associated with GBC prognosis. The expressions of MEG3 and ANRIL were higher in pcDNA-MEG3 and pcDNA-ANRIL-transfected cells than in empty vector-transfected cells in vitro. Most of the pcDNA-MEG3-transfected cells were in the G0-G1 phase, which showed reduced cell activity and clone counts and increased p53 and decreased cyclin D1, whereas the pcDNA-ANRIL-transfected cells were mostly in the S phase and showed contrasting behavior. Mice injected with pcDNA-MEG3-transfected cells had smaller and lighter tumors, decreased ki-67 levels, and increased caspase 3 levels, whereas those injected with pcDNA-ANRIL showed contrasting results. MEG3 can inhibit the proliferation of GBC cells and promote apoptosis, whereas ANRIL can improve the proliferation of gallbladder cells and inhibit apoptosis
