EIF3C and neoplasm: Flow cytometry was used to analyze the apoptosis when FaDu and 5-8F cells were infected with L.v-shEIF3C and L.v-shCtrl, it was found that the number of apoptotic cells in L.v-shEIF3C group was significantly more than that in L.v-shCtrl group (Figure 4A), indicating that down-regulation of EIF3C can promote apoptosis of tumor cells.
