PSAT1 and cancer: In line with the key processes identified by the pathway analysis, these genes had a range of functions including regulation of cell growth and proliferation and cancer development (PSAT1, Hint, SDCCAG10, p53 and C-myc), cell cycle (Ube2c, Hint, GMPS and p53), apoptosis (Hint), protein synthesis and folding (SDCCAG10, TOMM34, eEF1G), cardiac muscle growth (USMG5) and developmental processes (TBX3, FGFR1).
