[46] However, evidence has emerged that nicotine may suppress the growth inhibitory effects of trans-retinoic acid (RA) on lung cancer cells by inhibiting retinoic acid receptor (RAR) expression by inducing expression of an orphan RA receptor TR3, while inhibition of lung cancer cells by retinoid X receptor-selective (RXR-selective) retinoids was unaffected by nicotine. [47] These findings when coupled together suggest that when acting through specific nAchRs expressed in lung epithelial cells, nicotine, as well as compounds such as NNK that can be formed by exposure to nicotine, may help to expedite the pathogenesis of lung cancer in humans
