Soy intake acts hypolipidemically. Besides isoflavones, soy protein itself is suggested to influence plasma lipid concentrations. We investigated the effects of an alcohol-washed isoflavone-poor soy protein isolate on plasma and liver lipids and the hepatic expression of genes encoding proteins involved in cholesterol and fatty acid metabolism. Therefore, rats were fed diets containing 200 g/kg of either ethanol-extracted soy protein isolate or casein over 22 days. Rats fed soy protein isolate had markedly lower concentrations of liver cholesterol and lower concentrations of triglycerides in the liver and in plasma than rats fed casein (P<.05). Rats fed soy protein isolate had lower relative mRNA concentrations of sterol-regulatory element-binding protein (SREBP)-2, 3-hydroxy-3-methylglutaryl coenzyme A reductase, low-density lipoprotein receptor, cholesterol 7alpha-hydroxylase, apolipoprotein B, Delta9-desaturase and glucose-6-phosphate dehydrogenase in the liver than rats fed casein (P<.05). Hepatic mRNA concentration of SREBP-1c tended to be lower in rats fed soy protein isolate (P<.10). Hepatic mRNA concentrations of insulin-induced gene (Insig) 1 and Insig-2 and of microsomal triglyceride transfer protein, as well as plasma concentrations of free fatty acids, insulin and glucagon, were not different between the two groups. In conclusion, this study suggests that isoflavone-poor soy protein isolate affects cellular lipid homeostasis by the down-regulation of SREBPs and its target genes in the liver, which are involved in the synthesis of cholesterol and triglycerides.

Emus (Dromaius novaehollandiae) are farmed for their oil for pharmaceutical and cosmetic uses. This emu pituitary expressed sequence tag study was undertaken to identify novel transcripts in the emu pituitary to propel their identification and functional studies. By mapping reads derived from the Roche 454 GS Junior pyrosequencer to 8 reference species (human, mouse, chicken, zebra finch, fruit fly, turkey, round worm, and Carolina anole lizard) from the UniGene database, a total of 81,788 reads (53,312 mapped reads) were obtained and assembled with Reference Sequence (RefSeq). We annotated 6,676 potential emu genes by referencing 7 species (excluding lizard) and identified 1,232 potential genes common among 3 species (human, mouse, and chicken) with complete available reference genomes. Gene Ontology analysis revealed 376 Gene Ontology terms showing, with the highest counts, their involvements in biological processes, metabolism, and cellular components. These potential genes were detected to associate with 20 pathways including mitogen-activated protein kinase, insulin, neurotrophin signaling pathways, and carbohydrate digestion and absorption pathway. We also revealed a panel of tissue-specific genes including regulator of G-protein signaling protein (RGS), glucagon-like peptide receptor (GLPR), and growth hormone-inducible transmembrane protein (GHITM). Additionally, fatty acid binding protein (FABP), fatty acid desaturase (FAS), and stearoyl-coenzyme A desaturase (SCD), key enzyme genes in fat metabolism, were found to be also expressed in emu pituitary. This expressed sequence tag study represents the first step in functional characterization of emu pituitary gene expression and SNP identification for the improvement of fat production in the emu.
