Influence of 15 retinoic acid amides on urinary bladder carcinogenesis in the mouse.

abstract：:Several studies have indicated a correlation between the presence of inflammation and the development of cancer. The aim of our study was to determine if pulmonary neutrophils could transform the proximate respiratory carcinogen (+-)-trans-7,8-dihydroxy-7,8-dihydrobenzo[a]pyrene (B[a]P-7,8-diol), to an ultimate carcin...
