NCI Drug Dictionary


liposomal tretinoin 
An intravenous formulation of tretinoin (vitamin A acid or all-trans retinoic acid) encased in liposomes. Tretinoin is a naturally occurring retinoic acid agent that binds to and activates retinoic acid receptors (RAR), effecting changes in gene expression that lead to cell differentiation, decreased cell proliferation, and inhibition of carcinogenesis. This agent also inhibits telomerase, leading to telomere shortening and eventual apoptosis of certain tumor cell types. Liposome encapsulation extends the half-life of intravenously administered tretinoin. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
