Introduction: Visfatin/PBEF is a novel adipokine circulating inversely proportional to visceral fat mass and exerts insulin-mimetic effects; it is expressed in normal, inflamed and tumour tissues. Visfatin/PBEF has also been identified as NMPRTase, a key intracellular enzyme involved in NAD+ metabolism, replenishing NAD+ during cellular respiration. Inhibition of NMPRTase by the anti-cancer agent FK866 has been shown to induce apoptosis in tumours. Prosta...
