Polycyclic aromatic hydrocarbons (PAHs) such as 7, 12-dimethylbenzneanthracene (DMBA), due to long-term bioaccumulation cause serious physiological processes and behavioral dysfunctions such as cancer, ageing, and hypertension. Silk sericin (SS) is instrumental in cancer applications due to presence of flavonoids and carotenoids which are natural pigments, present in the layer of sericin that has antioxidant and antityrosinase activity. It reduces oxidative stress and suppresses cancer cytokines while interacting with reactive oxygen species (ROS) to stand against lipid peroxidation.
