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...

PURPOSE Heart-type fatty acid binding protein (H-FABP) is a sensitive marker of myocardial injury and predictor of worse prognosis in patients with pulmonary embolism (PE). Assessment of right ventricular dysfunction and pulmonary artery obstruction index (PAOI) with computed tomography (CT) has been reported as a predictor of mortality in PE. Therefore, we aimed to assess the correlation betwe...

PURPOSE We tested the hypothesis that serum heart fatty-acid binding protein (FABP), an early marker of myocardial necrosis, is related to prognosis of patients hospitalized because of worsening heart failure (HF). METHODS Sixty nine patients (64% men, age 66.6 +/- 11.0 years) with NYHA class II, III, IV HF (1, 18, and 50 patients, respectively) at hospital admission were followed for 6-12 (m...

Intestinal fatty acid binding protein (I-FABP) is believed to participate in the uptake, intracellular metabolism, and/or transport of long chain fatty acids within enterocytes. The 15.1-kDA rodent proteins is a member of a family of low Mr cytoplasmic proteins that have evolved to bind different ligands. We have now determined the nucleotide sequence of the gene encoding human I-FABP and defin...

BACKGROUND Timely recognition of acute coronary syndrome remains a challenge as many biomarkers, including troponin, remain negative in the first hours following the onset of chest pain. We assessed the diagnostic accuracy of heart-type fatty acid binding protein (H-FABP), a cardiac biomarker with potential value immediately post symptom onset. METHODS AND RESULTS Prospective monocentre diagn...

The role of intestinal fatty acid binding protein (I-FABP) in lipid metabolism remains elusive. To address this issue, normal human intestinal epithelial cells (HIEC-6) were transfected with cDNA to overexpress I-FABP and compared with cells treated with empty pQCXIP vector. I-FABP overexpression stimulated mitochondrial [U-14C]oleate oxidation to CO2 and acid-soluble metabolites via mechanisms...

BACKGROUND Early NEC symptoms are non-specific and diagnostic tests lack discriminative power. Intestinal fatty acid-binding protein (I-FABP), mainly located in small bowel enterocytes, is released into the blood following NEC-associated enterocyte disruption. Aim of this prospective cohort trial was to determine the diagnostic value of I-FABP measured in plasma (I-FABPp) and urine (I-FABPu) fo...

Background and Aim Gastrointestinal complications post cardiac surgery are infrequent but difficult to diagnose carry a high mortality. Plasma intestinal fatty acid-binding protein (I-FABP) concentrations the relationship between I-FABP, gastrointestinal dysfunction, postoperative outcomes were investigated in patients who developed dysfunction (acute injury [AGI] grade ≥2) those with normal fu...

BACKGROUND In this study, we aimed to investigate the importance of the use of heart-type fatty acid binding protein (H-FABP) in evaluating the myocardial damage in patients admitted to the emergency department with moderate to severe carbon monoxide (CO) poisoning. METHODS All patients admitted to the emergency department with severe acute CO intoxication were enrolled the study. The H-FABP ...
