CAT and Hepatic fibrosis: Zhang, Jiang, et al. (2021) demonstrated that the supplementation of lingonberry anthocyanins (25–100 μg/mL) inactivated hepatic stellate cells and CCL4‐induced liver fibrosis by suppressing hydroxyproline, malondialdehyde (MDA), and TGFβ/Smad/ERK signaling pathway, as well as by improving superoxide dismutase (SOD), glutathione peroxidase (GSH‐Px), and catalase (CAT) levels.
