Abstract
Some members of the tripartite motif-containing protein family have been reported as important regulators of carcinogenesis. In the present study, it was investigated whether tripartite motif-containing protein 44 (TRIM44) acts as a pro-oncogene through their over-expression in laryngeal squamous cell carcinoma. Its results showed that TRIM44 was up-regulated in tumor tissues and cell lines of laryngeal squamous cell carcinoma. In vitro, knockdown of TRIM44 significantly inhibited cell growth of laryngeal squamous cell carcinoma. Furthermore, TRIM44 knockdown inhibited tumor growth in nude mice in vivo, further suggesting the oncogenic activity of TRIM44 in laryngeal squamous cell carcinoma. Also, TRIM44 positively correlated with TLR4 at the mRNA and protein levels, and Si-RNA-NF-κB restrained laryngeal squamous cell carcinoma from proliferating. All indicated that TRIM44 might play a key role in tumor invasion through their over-expression and inhibition of TRIM44 is an effective strategy for the treatment of laryngeal squamous cell carcinoma.
