To provide a closer look at the impact of PPARγ on bladder cell progression, Yang et al. analyzed samples of both benign bladder and bladder cancer mucosal samples by fluorescence in situ hybridization (FISH) assay for expression of PPARγ, and the authors found 31% (8/21 samples) of the bladder cancer mucosal samples and 4.3% (1/23 samples) of benign bladder samples showed amplification [58]. Here, PPARG is linked to urinary bladder carcinoma.
