Initiation of growth arrest and apoptosis of MCF-7 mammary carcinoma cells by tributyrin, a triglyceride analogue of the short-chain fatty acid butyrate, is associated with mitochondrial activity
We investigated the effects of tributyrin, a triglyceride analogue of the short-chain fatty acid butyrate and an approved food additive, establishing induction of growth arrest and apoptosis of MCF-7 human mammary carcinoma cells. Transient increased mitochondria-associated bax, dissipation of the mitochondrial membrane potential (delta(psi)m), and caspase-3-independent cleavage of poly(ADP-ribose) polymerase are evident as early as 4 h after treatment of cells with tributyrin.
