Chen, Fang, and Wang (2020) reported that, compared with fish scale peptides (FSP), the MRPs of FSP showed better liver protection against alcohol induced liver injury in mice by increasing the activities of hepatic superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX), and reducing the levels of hepatic malondialdehyde (MDA) and triglyceride (TG) [9]. Here, CAT is linked to alcohol drinking.
