SOD1 and gastric ulcer: Recently, Guzman-Gomez et al. [49] suggested that a significant gastroprotective effect of SP was relevant to its phycobiliproteins, which repair gastric damage; its antioxidant properties by activating some enzymatic antioxidant mechanisms (SOD, CAT, and GPx); diminishing lipid peroxidation; and attenuating the inflammatory response, improving defences against the erosive lesion that characterizes the development of gastric ulcers.
