Figure 5. Down-regulation of TMEM98 represses the proliferation of FaDu and HSC-3 cells. (A) The expression level of TMEM98 was decreased in HNSCC cells treated with si-TMEM98 compared with cells treated with scramble. (B) The CCK-8 assay shows that down-regulation of TMEM98 inhibits the proliferation rate of HNSCC cells. (C) The migration assay indicates that down-regulation of TMEM98 represses the migration ability of HNSCC cells. *p < 0.05, **p < 0.01.
