Recently, several xenobiotics, including various drugs and environmental pollutants, have been reported to change plasma membrane characteristics, thereby altering cell physiology. Interestingly, it has been suggested that a cross talk between chemical-induced cellular membrane effects and DNA damages may be important for the final mutation outcome of genotoxic chemicals. Thus, effects on plasma membrane remodeling may give additional mechanistic explanations to how certain chemicals exert their carcinogenic effect. With respect to such effects, recent patents suggest to focus on plasma membrane and its components like caveolin-1 for cancer screening and chemotherapy. Here, we review the effects of environmental toxicants on cellular plasma membrane structure and function, and further describe possible implication for health and disease.
