Mechanism of Action

12.1 Mechanism of Action Tretinoin induces cytodifferentiation and decreased proliferation of APL cells in culture and in vivo . In APL patients, tretinoin treatment produces an initial maturation of the primitive promyelocytes derived from the leukemic clone, followed by a repopulation of the bone marrow and peripheral blood by normal, polyclonal hematopoietic cells in patients achieving complete remission (CR). The exact mechanism of action of tretinoin in APL is unknown.
