Wedelolactone from Eclipta alba inhibits lipopolysaccharide-enhanced cell proliferation of human renal mesangial cells via NF-κB signaling pathway.

Mesangial cells of glomerulus which could produce and degrade several ECMs, take part in the repair and update of mesangial matrix and GBM, regulate glomerular filtration rate, secret cytokines and phagocytose immune complexes contribute a lot to physiological functions and pathological reactions of glomerular. There inflammation response of abnormal proliferation induced by LPS could lead to renal damage. Herein, wedelolactone, an active chemical constituent extracted from leaves of Eclipta alba, was used to explore if it could be an effective inhibitor of the proliferative response of HRMCs. The effects of different concentration wedelolactone on the secretion of cytokines, cell viability and NF-κB pathway were all detected by qPCR, western blotting and ELISA. The results indicated that wedelolactone could inhibit the abnormal proliferation of HRMCs via regulating the activity of several key members of NF-κB signaling pathway.
