This study focuses on eight key apoptotic proteins, Akt (AKT1), Bcl-2, p53, Fas (receptor), Caspase-3, Caspase-8, Caspase-9, and XIAP (X-linked Inhibitor of Apoptosis Protein), due to their critical roles in apoptosis regulation and cancer progression. The gene discussed is TP53; the disease is cancer.
