The pooled analyses indicated the significant association of PEG10 overexpression with the risk of cancer, differentiation, lymph node metastasis and advanced TNM stage, but not with gender in cancer patients.
Subsequent knockdown of gene expression showed that CALCR, COPG2, GRB10, KLF14, MEST, and PEG10 were essential for cancer cell survival, resulting in reduced cell proliferation, G1 -phase arrest, and increased apoptosis.
PEG10 expression was observed in 148 of the 218 HCCs (67.9%) and was significantly correlated with younger age, female, higher Edmondson grade, microvascular invasion, intrahepatic metastasis, higher American Joint Committee on Cancer T-stage, and higher α-fetoprotein level.
