EIF2A and lip and oral cavity carcinoma: Together, these results demonstrate that dasatinib has strong anti‐growth, anti‐angiogenic and pro‐apoptotic effects on human oral cancer cells, which are mediated through the regulation of multiple targets, including Src, EGFR, STAT‐3, STAT‐5, PKB, ERK‐1/2, S6, eIF‐2α, GRP78, caspase‐9/3, Mcl‐1 and HIF‐1α.
