Another in vivo study showed that papaya juice demonstrated anti-obesity properties by reducing obesity markers, inflammation and oxidative stress in high-fat diet rats by upregulating SOD levels, attenuated serum malondialdehyde (MDA), PPAR-γ, lipid peroxidation, and ROS production at a treatment dose of 1 mL per 100 g of body weight [19]. The gene discussed is SOD1; the disease is Obesity.
