Retinoic acid-induced gene expression in normal and leukemic myeloid cells.

Retinoic acid has been shown to induce large accumulations of tissue transglutaminase in cultured myeloid cells. Addition of retinoic acid to mouse resident peritoneal macrophages increased the level of tissue transglutaminase mRNA within 30-60 min. Retinoic acid also increased tissue transglutaminase mRNA levels in human promyelocytic leukemia (HL-60) cells. These studies show that retinoic acid can induce acute alterations in specific gene expression in both normal and leukemic myeloid cells.
