MTOR and renal cell adenocarcinoma: In a Chinese study with 666 PCa and 708 cancer-free controls, Chen et al. [24] indicated that mTOR rs2295080 GT/GG genotypes had a protective effect on PCa risk, compared with the TT genotype, which was recently shown by Xu et al. in gastric cancer [25] and by Cao et al. in renal cell cancer [26].
