title: Control of neoplastic cell proliferation and differentiation by restoration of 4-hydroxynonenal physiological concentrations.
abstract: Several studies point to the existence of an inverse correlation between cellular lipid peroxidation and both cell proliferation and neoplastic transformation. In anaplastic cell lines products of membrane lipid peroxidation are very low or undetectable. Furthermore numerous results demonstrate effect of lipid peroxidation products on central biochemical pathways and intracellular signalling at physiological concentrations. 4-hydroxynonenal (HNE) is one of the most active products of lipid peroxidation. The restoration of HNE physiological concentrations in neoplastic cells may inhibit cell proliferation and modulate cell re-differentiation. This review try to summarize and critically discuss the effects of physiological concentrations of HNE on normal and neoplastic cell line.
