Knockdown of TMPRSS3 suppresses NPC progression in vivo. CNE-1 cells (1 × 10⁶ cells in 0.2 ml of PBS) stably transfected with sh-TMPRSS3 or sh-NC were injected subcutaneously into the left flank of female Balb/c nude mice. (a) Tumor volume was monitored every week and measured. (b) After 4 weeks, the mice were sacrificed, and the tumors were dissected out and weighed. *p < 0.05 versus sh-NC group.
