ABSTRACT
Ceramide is an endogenous lipid molecule generated by hydrolysis of membrane sphingomyelin, in response to cellular stimulation by hormones and cytokines. Ceramide appears to have a role in mediating biological responses in a wide variety of cell types. These responses are generally considered anti-proliferative, but endpoints are varied and include differentiation, growth inhibition, senescence and apoptotic cell death. Mechanisms for ceramide action involve regulation of protein phosphorylation via stimulation of a serine/threonine protein phosphatase, a proline-directed kinase and possibly other direct and/or indirect targets.
