摘要
OBJECTIVE:To study the differentiation of Th1/Th2 on the levels of transcription factors and cytokines production in patients with laryngeal squamous cell carcinoma in peripheral blood mononuclear cells (PBMC). In addition, the relation of p53 and T-bet, GATA3 expression was discussed for understanding the role of T-bet and GATA3 in metastasis. METHOD:The gene expression of Th1/Th2 type transcription factors T-bet, GATA3 and cytokines IFN-gamma, IL-4 were determined by RT-PCR and realtime RT-PCR from 49 patients with laryngeal squamous cell carcinoma and 30 normal controls. The expression of p53 was analyzed by immunohistochemistry. RESULT:Predominant expression of Th2 type cytokines was detected in 49 laryngeal squamous cell carcinoma patients. The expression rates of T-bet, GATA3, IFN-gamma and IL-4 was 42.86% (21/49), 71.43% (35/49), 26.53% (13/49), 63.27% (33/49) respectively. The expression rates of T-bet and IFN-gamma in patients were lower than in control group (P < 0.05), but the results of GATA3 and IL-4 were opposite (P < 0.05). The similar results were obtained by realtime PCR. The expression of p53 in patients was accompanied with lower expression of T-betmRNA and higher expression of GATA3mRNA. CONCLUSION:There is predominant expression of Th2 type transcription factors and cytokines in PBMC of laryngeal squamous cell carcinoma patients. T-bet and GATA3 can be used as reference indicators for the metastasis of laryngeal squamous cell carcinoma.
