Effects of Yomogi Tea on Lipid Metabolism in Renal Tubular HK-2 Cells.

ABSTRACT: Excessive accumulation of lipid droplets (LDs), their dynamics, and lipotoxicity are critical factors in the progression of metabolic disorders, including diabetic nephropathy. This study investigates the effects of yomogi tea (Mugwort tea), specifically its leaf infusion (YL) and powdered infusion (YP), on lipid metabolism in human kidney proximal tubular epithelial HK-2 cells under lipotoxic conditions induced by palmitic acid (PA). Both YL and YP significantly reduced intracellular triglyceride (TG) and free fatty acid (FFA) levels, with YP showing a trend toward greater efficacy. Mechanistic analysis revealed that yomogi tea regulates lipid metabolism by significantly downregulating mRNA expression of FAS and upregulating that of the lipolytic ATGL, while SCD-1 mRNA expression remained
