The mitochondrial trifunctional protein (TFP) is a multienzyme complex of the fatty acid beta-oxidation cycle. It is composed of four alpha-subunits (HADHA) harboring long-chain enoyl-CoA hydratase and long-chain L-3-hydroxyacyl-CoA dehydrogenase (LCHAD) and four beta-subunits (HADHB) harboring long-chain 3-ketoacyl-CoA thiolase (LKAT). Mutations in either subunit can result in TFP deficiency w...

Although the roles of the sterol response element binding protein-1 (SREBP1) and SREBP2 transcription factors in regulating fatty acid and cholesterol synthesis and uptake have been known for some time, it was recently discovered that 2 related microRNAs (miRs), miR-33a and miR-33b, are embedded in these genes. Studies indicate that miR-33a and miR-33b act with their host genes, Srebp2 and Sreb...

OBJECTIVE Candidate genes for non-alcoholic fatty liver disease (NAFLD) identified by a bioinformatics approach were examined for variant associations to quantitative traits of NAFLD-related phenotypes. RESEARCH DESIGN AND METHODS By integrating public database text mining, trans-organism protein-protein interaction transferal, and information on liver protein expression a protein-protein int...

BACKGROUND/OBJECTIVES The mitochondrial β-oxidation of fatty acids is a complex catabolic pathway. One of the enzymes of this pathway is the heterooctameric mitochondrial trifunctional protein (MTP), composed of four α- and β-subunits. Mutations in MTP genes (HADHA and HADHB), both located on chromosome 2p23, cause MTP deficiency, a rare autosomal recessive metabolic disorder characterized by d...

Rhodnius prolixus is an obligatory hematophagous insect, vector of Chagas disease. After blood meal, lipids are absorbed, metabolized, synthesized, and accumulated in the fat body. When necessary, stored mobilized, transported to other organs, or oxidized provide energy. Mitochondrial ?-oxidation a cyclic conserved pathway, where degradation long-chain fatty acids occurs contribute cellular ene...

Gut microbes play important roles in regulating fat storage and metabolism. Rhizoma coptidis (RC) and its main active compound, berberine, have either antimicrobial or anti-obesity activities. In the present study, we hypothesize that RC exerts anti-obesity effects that are likely mediated by mechanisms of regulating gut microbes and berberine may be a key compound of RC. Gut microbes and gluco...
