Glutathione S-Transferase Pi 1 (GSTP1) is suggested to protect cells against oxidative stress (Savic-Radojevic et al., 2007), which is involved in both peri-implantitis (Sánchez-Siles et al., 2016) and T2DM (Wright, Scism-Bacon & Glass, 2006) pathology. The gene discussed is GSTP1; the disease is Peri-Implantitis.
