Upregulation of cell cycle genes in HEK293 cells treated with 1 mmol/l exogenous NAD. Three-dimensional bar chart taken from SuperArray analysis software (cell cycle SuperArray; see Materials and methods) showing fold difference in expression levels for 84 cell cycle related genes comparing vehicle treated HEK293 cells (control sample) with nicotinamide adenine dinucleotide (NAD) treated HEK293 cells (test sample). Individual genes with a greater than twofold expression change can be found in Table 2. NAD, nicotinamide adenine dinucleotide.
