Dose–response effect of visfatin/Nampt on the mRNA expression of interleukin-6, keratinocyte chemoattractant and monocyte chemoattractant protein 1 by murine osteoblasts. Murine osteoblasts were treated with recombinant visfatin/nicotinamide phosphoribosyltransferase (Nampt) at 20, 50 and 100 nM for 24 hours. Quantitative reverse transcriptase-polymerase chain reaction analysis of mRNA levels of (left to right) interleukin-6, keratinocyte chemoattractant and monocyte chemoattractant protein 1 relative to that of hypoxanthine–guanine phosphoribosyltransferase. Data are mean ± standard error of the mean of four experiments.
