Figure 5From: Leptin promotes melanoma tumor growth in mice related to increasing circulating endothelial progenitor cells numbers and plasma NO productionThe plasma concentration of NOx. The plasma concentration of NOx significantly increased in leptin group and significantly decreased in 9f8 treated mice compare to respective control groups. Furthermore leptin treated mice had significantly more NOx levels than 9F8 group. * (p < 0.05).Back to article page
