The same was observed for genes involved growth arrest and DNA damage-inducible 45A (GADD45A: involved in the regulation of DNA repair and cell cycle control), prostaglandin-endoperoxide synthase 2 (PTGS2: which mediates responses to physiological stresses including infection and inflammation) and master regulator of cell cycle (MYC: a transcription factor that can induce proliferation or apoptosis). This evidence concerns the gene PTGS2 and infection.
