Cyclic AMP potentiates the retinoic acid-induced expression of tissue transglutaminase in peritoneal macrophages. 1986

M P Murtaugh, and W T Moore, and P J Davies

Fresh serum and retinoids induce the expression of tissue transglutaminase in cultured mouse resident peritoneal macrophages. Analogues of cyclic AMP, such as dibutyryl cyclic AMP, and agents that increase intracellular cyclic AMP levels enhance the induction. Dibutyryl cyclic AMP alone has little effect on transglutaminase expression, but it increases the sensitivity of macrophages to low concentrations of either serum or retinoic acid. Dibutyryl cyclic AMP potentiates the transglutaminase-inducing activity of both free retinoic acid and retinoic acid bound to the serum retinol-binding protein. Pretreating macrophages with dibutyryl cyclic AMP or retinoic acid does not prime the cells to respond to the other agent; instead, both agents must be present simultaneously to obtain the synergistic induction of transglutaminase. Our studies suggest that the modulation of intracellular cyclic AMP levels may have pronounced effects on retinoic acid-induced gene expression in myeloid cells.

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D011503	Transglutaminases	Transglutaminases catalyze cross-linking of proteins at a GLUTAMINE in one chain with LYSINE in another chain. They include keratinocyte transglutaminase (TGM1 or TGK), tissue transglutaminase (TGM2 or TGC), plasma transglutaminase involved with coagulation (FACTOR XIII and FACTOR XIIIa), hair follicle transglutaminase, and prostate transglutaminase. Although structures differ, they share an active site (YGQCW) and strict CALCIUM dependence.
