Chronic ethanol consumption is a prominent cause of liver disease worldwide. Dysregulation of an important lipid uptake and trafficking gene, liver-fatty acid binding protein (L-FABP), may contribute to alterations in lipid homeostasis during early-stage alcoholic liver. We have reported the detrimental effects of ethanol on the expression of L-FABP and hypothesize this may deleteriously impact...

The rat contains at least three homologous cytosolic proteins that bind long chain fatty acids, termed liver (L-), intestinal (I-), and heart (H-) fatty acid binding protein (FABP). I-FABP mRNA is confined to the gastrointestinal tract while L-FABP mRNA is abundantly represented in hepatocytes as well as enterocytes. We have isolated a rat heart FABP cDNA clone and determined the pattern of H-F...

Objective: To test the hypothesis that myocardium specific proteins may be useful markers for evaluating the severity of congestive heart failure. Methods: Serum concentrations of myosin light chain I (MLC-I), heart fatty acid binding protein (H-FABP), creatine kinase isoenzyme MB (CK-MB), and troponin T (TnT) and plasma concentrations of brain natriuretic peptide (BNP) were determined in 48 pa...

4-Hydroxynonenal (4-HNE) is a reactive α,β-unsaturated aldehyde produced during oxidative stress and subsequent lipid peroxidation of polyunsaturated fatty acids. The reactivity of 4-HNE towards DNA and nucleophilic amino acids has been well established. In this report, using proteomic approaches, liver fatty acid-binding protein (L-FABP) is identified as a target for modification by 4-HNE. Thi...

BACKGROUND Detection of brain injury by serum markers is not a standard procedure in clinical practice, although several proteins, such as S100B, neuron-specific enolase (NSE), myelin basic protein, and glial fibrillary acidic protein, show promising results. We investigated the tissue distribution of brain- and heart-type fatty acid-binding proteins (B-FABP and H-FABP) in segments of the human...

Application of acute kidney injury (AKI) biomarkers with consideration of nonrenal conditions and systemic severity has not been sufficiently determined. Herein, urinary neutrophil gelatinase-associated lipocalin (NGAL), L-type fatty acid-binding protein (L-FABP) and nonrenal disorders, including inflammation, hypoperfusion and liver dysfunction, were evaluated in 249 critically ill patients tr...

The assessment of biomarkers to detect renal injury has been studied before, but the sensitivity and specificity of urinary and serum profiles of these markers still need to be improved. One of the promising new markers for detection of renal injury is the family of 15 kDa cytoplasmic fatty acid-binding proteins (FABPs). Remarkably, however, the application of FABP as marker for renal injury du...

Liver weight is an important economic trait in the fatty goose liver industry. Liver-type fatty acid binding protein (L-FABP) is involved in the formation and metabolism of fatty acids. Thus, we hypothesized that sequence polymorphisms in L-FABP were associated with fatty liver weight in goose. We first isolated, sequenced, and characterized the goose L-FABP gene, which had not been previously ...

The effects of intestinal and liver fatty acid binding protein (I- and L-FABP, respectively) expression on single-cell fatty acid uptake, internalization, and cytoplasmic diffusion were determined in transfected L cell fibroblasts. These parameters were measured using the nonesterifiable fluorescent fatty acid probe 12- N-methyl-(7-nitrobenz-2-oxa-1,3-diazol)aminostearate (NBD-stearate) and flu...
