Expression of human ether-a-go-go-related gene in laryngeal carcinoma / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To study the expression of human ether-α-go-go-related gene (herg) and hERG protein expressed by the gene in laryngeal carcinoma compared with the control group(mucosa adjacent to cancer of 2 cm).@*METHOD@#Expression of herg and hERG protein was detected by immunohistochemistry (SP) and real-time PCR in resected tissue of laryngeal carcinoma and mucosa adjacent to cancer of 2 cm.@*RESULT@#(1) By immunohistochemistry, the positive expression rate of hERG in laryngeal carcinoma was 76.7% (23/30), while it was 10.0% (2/20) in mucosa adjacent to cancer of 2 cm, the difference between which was statistically significant (P < 0.05). (2) By real-time PCR, the expression level of herg mRNA in laryngeal carcinoma is 2.25 times higher than that in mucosa adjacent to cancer of 2 cm.@*CONCLUSION@#Herg is highly expressed in tissue of laryngeal carcinoma, and it may be have some relevance to the happening and development of laryngeal carcinoma.
