To explore the relationship between STK15 gene abnormal expression and laryngeal carcinoma. Methods: Tumor tissues and matched normal tissues were taken from 55 LSCC patients. Semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) was used to detect STK15 expression in 110 specimens. Results: In 38 of the 55 cases (69.1%), the STK15 expression at the mRNA levels was higher than that of the paired normal tissue. The ratio of ADV (average density value) of STK15 gene to ADV of b-actin gene was 1.220.49 in the cancer tissue, and 0.990.54 in the paired normal tissue with a significant difference (t=4.539, P<0.01). Conclusion: There was obvious association between the STK15 overexpression and laryngeal carcinoma. It may serve as an alternative mechanism of activating the pathogenesis of human laryngeal squamous cell carcinoma.
