title: Suppression of S-phase kinase-associated protein 2 induces apoptosis and inhibits tumor growth in human laryngeal cancer.
abstract: S-phase kinase-associated protein 2 (Skp2) is related to cellular proliferation and differentiation in laryngeal carcinoma. This study aimed to investigate the effect of Skp-2 suppression on p27 expression, cellular proliferation, apoptosis, and tumor growth in laryngeal squamous cell carcinoma. Skp2 was stably suppressed in Hep2 laryngeal carcinoma cells by lentivirus siRNA technology and Hep2-siRNA was then inoculated into nude mice. The siRNA-induced suppression of Skp2 increased p27 expression, decreased cellular proliferation, and increased apoptosis in human laryngeal carcinoma cells and tumors, indicating that Skp2 is a viable target in the gene therapy treatment of human laryngeal carcinoma.
