Prostaglandin production by methylcholanthrene-transformed mouse BALB/3T3: inhibition by cytochalasin B. 1976

S S Pong, and L Levine

Cytochalasin B inhibits the production of prostaglandins by serum-, thrombin-, and bradykinin-stimulated MC5-5 cells. The serum-stimulated release of arachidonic acid from cellular phospholipids also is inhibited. Cytochalasin B does not affect the cells' prostaglandin synthetase activity when exogenous arachidonic acid is present. Deacylation of phospholipids may be the step affected by cytochalasin B possibly as a result of disruption of microfilament organization. Colchicine and vinblastine, two drugs that can disrupt microtubule organization, do not inhibit prostaglandin production by cells.

D011453	Prostaglandins	A group of compounds derived from unsaturated 20-carbon fatty acids, primarily arachidonic acid, via the cyclooxygenase pathway. They are extremely potent mediators of a diverse group of physiological processes.	Prostaglandin,Prostanoid,Prostanoids
D001920	Bradykinin	A nonapeptide messenger that is enzymatically produced from KALLIDIN in the blood where it is a potent but short-lived agent of arteriolar dilation and increased capillary permeability. Bradykinin is also released from MAST CELLS during asthma attacks, from gut walls as a gastrointestinal vasodilator, from damaged tissues as a pain signal, and may be a neurotransmitter.
