A thioesterase present in the uropygial gland of mallard functions in conjunction with fatty acid synthase to produce short chain acids in this gland (deRenobales, M., Rogers, L., and Kolattukudy, P. E. (1980) Arch. Biochem. Biophys. 205,464-477). This enzyme, capable of releasing short chain acids from fatty acid synthase, was purified to near homogeneity. This S-acyl fatty acid synthase thioe...

Evasion of death receptor ligand-induced apoptosis contributs to cancer development and progression. To better understand mechanisms conferring resistance to death ligands, we screened an siRNA library to identify sequences that sensitize resistant cells to fas activating antibody (CH-11). From this screen, we identified the Sterol-Regulatory Element-Binding Protein 1 (SREBP1), a transcription ...

Hepatic fatty acid synthase is regulated by nutritional state. Starvation decreases and refeeding increases the activity of avian fatty acid synthase, principally by regulating transcription of the gene (Back, B. W., Goldman, M. J., Fisch, J.E., Ochs, R.A., and Goodridge, A.G. (1986) J. Biol. Chem. 261, 4190-4197). In chick embryo hepatocytes in culture, the stimulatory effect of feeding on fat...

BACKGROUND Chronic kidney disease (CKD) results in hypertriglyceridemia which is largely due to impaired clearance of triglyceride-rich lipoproteins occasioned by downregulation of lipoprotein lipase and very low-density lipoprotein (LDL) receptor in the skeletal muscle and adipose tissue and of hepatic lipase and LDL receptor-related protein in the liver. However, data on the effect of CKD on ...

The effects of low extracellular pH and intracellular accumulation of weak organic acids were compared with respect to fatty acid synthesis by whole cells of Mycobacterium tuberculosis and Mycobacterium smegmatis. The profile of fatty acids synthesized during exposure to benzoic, nicotinic, or pyrazinoic acids, as well as that observed during intracellular hydrolysis of the corresponding amides...

Background: With the increasing concern for health and nutrition, dietary fat has attracted considerable attention. The composition of fatty acids in the diet is important because they are associated with major diseases including cancers, diabetes, and cardiovascular disease. The fatty acid synthase (FASN) and stearoyl-CoA desaturase (delta-9-desaturase) (SCD) genes affect fatty acid compositio...

A new fatty acid synthase off-loading domain. Fatty (FAS) usually releases its products by hydrolysis or transesterification. Here, an α-oxoamine domain is identified in a cyanobacterial type I FAS. This the acyl chain through condensation with L-serine, offering novel pathway to α-amino ketones that share similarities sphingolipid precursors. More information can be found Research Article A. E...
