The NAMPT/SIRT7/SOD2 axis regulates alveolar progenitor cell renewal and pulmonary fibrosis [scRNA-seq]

ABSTRACT: We employed single-cell RNA sequencing using the 10x Genomics platform to investigate the role of nicotinamide phosphoribosyltransferase (NAMPT), a key enzyme in NAD+ biosynthesis, in AT2 cells in the lung. NAMPT has been implicated in regulating stem cell function, mitochondrial bioenergetics, apoptosis, and senescence in neurodegenerative diseases, endothelial cells, and human iPS cells. Single-cell lung suspensions were prepared from Nampt AT2 conditional knockout and control mice at day 0 and day 4 post-bleomycin injury. scRNA-seq was performed on FACS-sorted Epcam+ and CD45+ live cells, and purified cells were clustered to evaluate NAMPT function in AT2 and immune cells.
