Myocyte Apoptosis

Fatty acid-binding protein 3 (FABP3), a low-molecular-weight protein, participates in lipid transportation, storage, signaling transduction, oxidation, and transcription regulation. Here, we investigated the expression and function of FABP3 in ischemic heart diseases and explored the mechanisms by which FABP3 affected remodeling after myocardial infarction (MI). We showed that ischemic or hypoxic conditions upregulated FABP3 expression in vivo and in vitro. Notably, overexpression of FABP3 induced more myocyte apoptosis in the infarction and border areas and aggravated cardiac dysfunction, with lower left ventricular ejection fraction. Meanwhile, overexpression of FABP3 drastically promoted death and apoptosis of neonatal rat ventricular cardiomyocytes under hypoxia. Furthermore, deficiency of FABP3 exerted protective effects against ischemic heart injuries by decreasing cardiac myocyte apoptosis and heart remodeling after MI. We found that overexpression of FABP3 upregulated the phosphorylation of MAPK signaling pathway and decreased phosphorylated Akt levels, which may account for the augmentation of apoptosis and remodeling after MI. To the best of our knowledge, this is the first study to demonstrate that deficiency of FABP3 would protect cardiac myocytes from apoptosis and alleviate cardiac remodeling after MI, suggesting FABP3 as a potential target to preserve cardiac function after MI. NEW & NOTEWORTHY It is an undisputable fact that myocyte apoptosis plays a crucial role in cardiac remodeling and the development of heart failure after myocardial infarction. Here, fatty acid-binding protein 3 deficiency improved myocardial structural remodeling and function by decreasing cell apoptosis and regulating MAPK signaling pathways. We suppose that fatty acid-binding protein 3 may be regarded as a potential intervention approach to preserve cardiomyocytes during myocardial infarction.

This review summarizes the data on the diagnostic value of determining the fatty acid-binding protein (FABP) in urological and nephrological diseases. A physiological role of this protein in the pathogenesis of malignant neoplasms of the kidney, bladder, and prostate was analyzed. The dynamics of FABP in serum and urine with decreased renal function was studied: this protein is considered as a diagnostic and prognostic marker for chronic kidney disease and acute renal injury. The value of FABP for early screening of patients with obstructive nephropathy was revealed, and its role in predicting the restoration of kidney function was studied: the dynamics of FABP content can characterize the process of graft recovery, determine the need for hemodialysis. In patients with oligozooastenospermia, a reduced content of FABP in the ejaculate was registered, which was probably an adverse sign indicating a violation of male fertility.
