Abstract
Objective To detect the expression of human telomerase reverse transcriptase (hTERT) mRNA in the melanoma, and to analyze the relationship between the expression and subtypes and clinicopathological features of melanoma. Methods Expression of hTERT mRNA was detected by real-time quantitative PCR in 64 cases of melanoma and 30 cases of nevus. SPSS 17.0 software was used to analyze the relationship between hTERT mRNA expression and clinical pathological features of melanoma. Results The relative expression of hTERT mRNA in melanoma tissues was higher than that in nevus tissues [(52.43±5.42) vs (21.38±3.73), t = 4.72, P = 0.000]. The expression of hTERT mRNA in melanoma had no significant correlation with age, gender, ethnicity (all P > 0.05), but had relationship with subtypes, lymph node metastasis, Clark classification (all P 0.05). Conclusions The expression of hTERT mRNA in melanoma is high, especially in mucosal melanoma. hTERT may play an important role in the occurrence and development of melanoma.
