Nicotine has several health hazards regarding carcinogenic potential. It also imparts increased risk for respiratory, cardiovascular, and gastrointestinal disorders. Several mechanisms have been proposed for the carcinogenic potential, including effects on cell proliferation, inducing oxidative stress, DNA mutation, or inhibition of apoptosis. The cotinine metabolite is generally thought to have effects similar to nicotine in some experimental systems. The purpose of this study was to assess the nicotine and cotinine cytotoxicity on MRC-5 lung fibroblasts. The pulmonary fibroblasts were treated with various concentrations of nicotine or cotinine (in the range 1 µM – 2 mM) for 24 or 48 h …
