Abstract:
Objective To study the functions of peroxisome proliferator-activated receptorγ(PPARγ), retinoic acid X receptor α (RXRα) and cyclooxygenase 2 (COX-2) in the carcinogenesis of cervical squamous cell carcinoma (SCC). Methods The expressions of PPARγ, RXRα and COX-2 in 17 cases of normal cervical epithelium (NCE), 72 cases of squamous intraepithelial lesion (SIL) and 42 cases of cervical SCC were detected with immunohistochemical method respectively. Results The positive expression rates of PPARγ in the NCE, SIL and cervical SCC group were 23.5 % (4/17), 58.3 % (42/72) and 83.3 % (35/42) respectively; the positive expression rates of RXRα in the NCE, SIL and cervical SCC group were 29.4 %(5/17), 54.2 % (39/72) and 90.5 % (38/42) respectively. No significant expression of COX-2 was found in the NCE, while the positive expression rates of COX-2 in SIL and cervical SCC were 36.1 % (26/72) and 57.1 %(24/42) respectively. The positive expression rates of PPARγ, RXRαand COX-2 in high-grade SIL group were higher than those in low-grade SIL group (all P<0.05). In cervical SCC group, the positive expression rate of COX-2 with lymph node metastasis was higher than that without lymph node metastasis (χ2= 3.98, P= 0.04). Conclusion PPARγ, RXRαand COX-2 might be all involved in the carcinogenesis of SCC.
