Mangosteen peel extract (Garcinia mangostana L.) as protective agent in glucose-induced mesangial cell as in vitro model of diabetic glomerulosclerosis

This study aims to evaluate the activity of mangosteen peels extract (MPE) as protection agent on induced-glucose mesangial cells (SV40 MES 13 cell line (Glomerular Mesangial Kidney, Mus Musculus)).
MPE was performed based on maceration method. Cytotoxic assay was performed based on MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium) method, while the level of TGF-β1 (Transforming growth factor-β1) and fibronectin in glucose-induced mesangial cells were assayed and determined using ELISA KIT.
In viability assay, MPE 5 and 20 µg/ml has the highest activity to increase cells proliferation in glucose-induced mesangial cells at 5, 10, and 15 days of incubation in glucose concentration (5 and 25 mM) (P MPE can increase cell proliferation in glucose-induced mesangial cells and significantly reduce the level of TGF-β1 and fibronectin. MPE activity has correlates to inhibit the diabetic glomerulosclerosis condition and may increase mesangial cell proliferation.
