Expression of E2F2. a Differential expression of E2F2 between various tumors or specific tumor subtypes and adjacent normal tissues. b MG cells exhibit an oval, short spindle or polygonal shape, with a normal nuclear-to-cytoplasmic ratio (× 40). c MGC cells display an oval or round shape with significant atypia and tight intercellular connections (× 40). d Differential E2F2 mRNA and protein expression between primary MG and MGC cells. *P < 0.05; **P < 0.01; ***P < 0.001
