NAMPT and neoplasm: We observed a positive correlation of NAMPT with GCSF and G-CSF receptor (GCSFR) gene expression (Figure 1a), and the negative correlation with interferon receptor (IFNAR) subunits 1 and 2 in head and neck cancer (HNC) tumor tissue (Figure 1b), demonstrating the enhanced NAMPT expression in the lack of type I IFN signaling.
