The early detection of breast cancer, the most common malignant tumor disease in women worldwide, relies on mammography and self breast examination. Here we evaluated the concentration of nicotinamide phosphoribosyltransferase (NAMPT), vascular endothelial growth factor (VEGF) and human epidermal growth factor receptor-2 (HER2) in serum and their expression in breast tissues associated with the...

BACKGROUND Emerging evidence reveals that nicotinamide phosphoribosyltransferase (NAMPT) has a significant role in the pathophysiology of the inflammatory process. NAMPT inhibition has a beneficial effect in the treatment of a variety of inflammatory diseases. However, it remains unclear whether NAMPT inhibition has an impact on ischemia-reperfusion (I/R)-induced acute lung injury. In this stud...

Type 2 diabetes mellitus (T2DM) is considered a leading factor of cardiovascular (CV) events in general population. Impairment of endogenous endothelial repair system plays a pivotal role in T2DM-induced microangiopathy and macroangiopathy and, however, may contribute in CV risk and outcomes. Recent studies have shown that the nicotinamide phosphoribosyl transferase (NAMPT) currently known as v...

The P7C3 class of aminopropyl carbazole chemicals fosters the survival of neurons in a variety of rodent models of neurodegeneration or nerve cell injury. To uncover its mechanism of action, an active derivative of P7C3 was modified to contain both a benzophenone for photocrosslinking and an alkyne for CLICK chemistry. This derivative was found to bind nicotinamide phosphoribosyltransferase (NA...

Obesity and type 2 diabetes mellitus are major health concerns worldwide. In obese-type diabetic patients, the function of central brain clock in hypothalamus, as well rhythmicity white adipose tissue (WAT), reduced. To better understand how peripheral clocks (WAT) synchronized, we assessed importance for daily WAT rhythms. We compared gene expression rhythms core genes (Bmal1, Per2, Cry1, Cry2...

Disruption of pancreatic clock genes impairs pancreatic beta-cell function, leading to the onset of diabetes. Despite the importance of pancreatic alpha-cells in the regulation of glucose homeostasis and in diabetes pathophysiology, nothing is known about the role of clock genes in these cells. Here, we identify the clock gene Rev-erb alpha as a new intracellular regulator of glucagon secretion...

Nicotinamide phosphoribosyltransferase (NAMPT) is a crucial enzyme in the biosynthesis of intracellular NAD+. NAMPT inhibitors have potent anticancer activity in several preclinical models by depleting NAD+ and ATP levels. Recently, we demonstrated that CD73 enables the utilization of extracellular NAD+/nicotinamide mononucleotide (NMN) by converting them to Nicotinamide riboside (NR), which ca...

Aging is the predominant risk factor for cardiovascular diseases and contributes to a considerably more severe outcome in patients with acute myocardial infarction. Resveratrol, a polyphenol found in red wine, is a caloric restriction mimetic with potential anti-aging properties which has emerged as a beneficial nutraceutical for patients with cardiovascular disease. Although resveratrol is wid...

Coronary heart disease (CHD) is a generic designation for group of related syndromes resulting from myocardial ischemia – an imbalance between cardiac blood supply (perfusion) and oxygen demand. Visfatin (VF) recently discovered adipokine with different functions, mainly found in visceral adipose tissue mimics insulin lowering plasma glucose levels and, emerges as player the development progres...

NAD salvage is one of the pathways used to generate NAD in mammals. Nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme in this pathway, uses nicotinamide (NAM) to generate nicotinamide mononucleotide (NMN). NMN is one of the main precursors of NAD synthesis in cells. Our previous study showed the importance of NAMPT in maintaining NAD levels in pancreatic ductal adenocarci...
