p53 plays a role in regulation or progression through the cell cycle, apoptosis, and genomic stability by means of several mechanisms: • It can activate DNA repair proteins when DNA has sustained damage. Thus, it may be an important factor in aging. • It can arrest growth by holding the cell cycle at the G1/S regulation point on DNA damage recognition—if it holds the cell her… WebNov 1, 2014 · This indicates that the effects of p53 on glycolysis are remarkable and tissue-specific. 1.3.
