In this study, we investigated the effects of a trans -fatty acid (TFA) diet on the liver in adult (25 wk) and old (60 wk) senescence-accelerated mice (SAMP8 strain) of both sexes. (biomedcentral.com)
The intestinal microbiota impact obesity, fatty liver diseases, and weight loss by way of the ability to induce the expression of genes related to lipid metabolism ( 6 , 10 ). (frontiersin.org)
Serum elevations of ALT activity are rarely observed except in parenchymal liver disease, since ALT is a more liver-specific enzyme than asparate aminotransferase (AST). (cdc.gov)

We show that compartmentalization of these NAD + dependent reactions together with a dedicated NADH/NAD + recycling enzyme supports optimal growth when an increased demand for anabolic reactions taxes cellular redox balance. (biorxiv.org)

The molecular defect occurs in the mitochondrial trifunctional protein (MTP). (medscape.com)

Female mice demonstrated higher expression of antioxidant enzymes (SOD-1, SOD-2, and Ref-1) and lipogenic enzymes (FASN, ACLY) compared to male mice. (biomedcentral.com)

The body uses methionine to make proteins and other important compounds. (medlineplus.gov)
Of the three compounds, only LLNL-02 successfully permeates the membrane. (llnl.gov)

During fellowship, he became interested in the role of the protein α -synuclein in Parkinson's disease (PD) while conducting research in the lab of Dr. Dennis Selkoe. (apdaparkinson.org)

In enzymology, a fatty-acyl-CoA-transporting ATPase (EC 7.6.2.4) is an enzyme that catalyzes the chemical reaction ATP + H2O + fatty acyl CoAcis ⇌ {\displaystyle \rightleftharpoons } ADP + phosphate + fatty acyl CoAtrans The 3 substrates of this enzyme are ATP, H2O, and fatty acyl CoAcis, whereas its 3 products are ADP, phosphate, and fatty acyl CoAtrans.
