The p53 tumor suppressor protein regulates the cellular response to multiple stresses, including DNA damage and oxidative stress. Activation of p53 can lead to cell cycle arrest and DNA repair, or apoptosis (1). Activated p53 transcription factor regulates the expression of multiple genes that regulate cell metabolism and the cell cycle. One p53-inducible gene is C12orf5, which encodes for a fructose-2,6-bisphosphatase known as TIGAR. TP53-inducible glycolysis and apoptosis regulator (TIGAR) protects cells from oxidative stress as it negatively regulates glycolysis and reduces the production of reactive oxygen species (ROS) in cells (2,3). Research studies demonstrate that knockdown of TIGAR expression induces autophagy and apoptosis (4,5), and its expression protects cells from ROS-related cell death (6,7). Additional studies show that TIGAR promotes cell cycle arrest and supports dephosphorylation of the retinoblastoma (Rb) protein (8).
