Strong CysLT1R expression was noted in several urological cancer samples, including renal cell carcinoma [64,68], bladder cancer (transitional cell carcinoma) [64,65], prostate cancer and prostatic intraepithelial neoplasia [64,67] and testicular cancer (including seminoma, embryonal carcinoma, yolk sac tumors, choriocarcinoma and teratoma) [64,66], than in the corresponding normal tissue, and more extensive and intense expression was noted in cancer with a higher grade or an advanced stage. This evidence concerns the gene CYSLTR1 and cancer.
