All-trans retinoic acid (all-tranz REH-tih-NOH-ik A-sid)
A nutrient that that body needs in small amounts to function and stay healthy. All-trans retinoic acid is made in the body from vitamin A and helps cells to grow and develop, especially in the embryo. A form of all-trans retinoic acid made in the laboratory is put on the skin to treat conditions such as acne and is taken by mouth to treat acute promyelocytic leukemia (a fast-growing cancer in which there are too many immature blood-forming cells in the blood and bone marrow). All-trans retinoic acid is being studied in the prevention and treatment of other types of cancer. Also called ATRA, retinoic acid, tretinoin, and vitamin A acid.
