Latest Antioxidant News and Research

Palmatine improved fatty liver markers in a preclinical type 2 diabetes study

Researchers used a bioinformatics-plus-rat-model approach to investigate how palmatine may help treat T2DM-associated MASLD, identifying five core targets: ADRB2, BCL3, EGR1, FOS, and MAP3K8. In rats, palmatine improved liver injury, inflammation, oxidative stress, glycolipid metabolism, steatosis, and fibrosis, while reducing apoptosis-related signaling, providing a preclinical foundation for further therapeutic study.
