Integrins (ITGs) are mediators of cell-cell and cell-matrix interactions, which are also associated with embryo implantation processes by controlling the interaction of blastocyst with endometrium. During early pregnancy,Integrin beta 8 (ITGB8) has been shown to interact with latent transforming growth factor (TGF) beta 1 (TGFB1) at the fetomaternal interface. integrin beta-8 (ITGB8) when over-expressed, is correlated with the gefitinib resistance of hepatic cancer cell line HepG2/G. After ITGB8 silencing, the drug resistance is reversed as the cell proliferation decreases and apoptosis rate increases significantly by gefitinib treatment when compared to HepG2/G.
