Effect of BST2 on apoptosis of OSCC cells. After H157 and HSC-2 cell lines were transfected with pcDNA3.1-BST2, BST2 expression control group (pcDNA3.1), siBST2-1#, siBST2-2# or siRNA control (NC), A – apoptosis of OSCC cells was detected by flow cytometry and the quantification of apoptosis was calculated and listed on the left side; B – protein expression of Bcl-2, Bax and cleaved caspase-3 was determined by western blot. Student’s t test was used for statistical analysis

^***p < 0.01; ^**p < 0.05 versus control.
