摘要：

Objective: To analyze the mRNA and protein expression of cannabinoid receptors CBI and CB2 in chromophobe renal cell carcinoma (ChRCC) and renal oncocytoma (RO). Design and methods: Fresh and formalin-fixed tissue samples of ChRCC and RO were analyzed by using real-time quantitative RT-PCR and immunohistochemical techniques (n=40). Results: Quantitative RT-PCR analysis showed that CB1 mRNA was underexpressed by 12-fold in ChRCC and had a variable expression in RO. CBI protein showed intense positive immunostaining in both neoplasms. Both CB2 mRNA and protein were not expressed in tumor and non tumor renal tissue. Conclusion: This distinct immunoprofile may eventually be used as an additional tool with practical interest in the differential diagnosis of renal tumors.
