Description générale

Visfatin is also called pre-B cell colony enhancing factor, nicotinamide phosphoribosyltransferase, pre-B-cell colony-enhancing factor 1 homolog, NAmPRTase, Nampt and PBEF. Visfatin is an adipocytokine produced by visceral fat.

Actions biochimiques/physiologiques

Visfatin has a role in mammalian nicotinamide adenine dinucleotide (NAD+) biosynthesis. Studies have shown that mice deficient in visfatin in the forebrain excitatory neurons show hyperactivity, diminished anxiety-like behaviors and impaired learning and memory. It has also been shown that visfatin stimulates glucose uptake and adenosine monophosphate-activated protein kinase (AMPK) phosphorylation in mouse C2C12 skeletal muscle cells.

Nicotinamide adenine dinucleotide (NAD(+)) is an essential coenzyme/cosubstrate for many biological processes in cellular metabolism. The rate-limiting step in the major pathway of mammalian NAD(+) biosynthesis is mediated by nicotinamide phosphoribosyltransferase (Nampt). Previously, we showed that mice lacking Nampt in

Hypoxia-induced apoptosis of cementoblasts (OCCM-30) may be harmful to orthodontic treatment. Hypoxia-inducible factor 1-alpha (HIF-1α) mediates the biological effects during hypoxia. Little is known about the survival mechanism capable to counteract cementoblast apoptosis. We aimed to investigate the potential roles
