Abstract

Abstract: Hepatic and renal extracellular matrix (ECM) turnover associated with diabetes and potential beneficial effects of yellow lupin extract (YLE) need further investigations. The aim of this study was to explore the effect of yellow Lupinus luteus extract (YLE) on renal and hepatic ECM under diabetes. Composition of YLE performed by LC‐ESI‐MS. Diabetes (DM) was induced in rats by alloxan (250 mg/kg, ip). Normal and diabetic rats received 100 mg/kg of YLE for 1 month. ECM was assessed by ELISA. Gelatinases and collagenases were analyzed by a colorimetric assay. Histology was performed on sections of liver and kidney. In the liver, diabetes increases collagen, laminin, and fibronectin contents, respectively, by 49% ( p < .01), 56% ( p < .01), and 67% ( p < .05) compared to control rats. In the kidney, total collagen and laminin contents were increased by 91% ( p < .01) and 35% ( p < .01) in the DM group, while fibronectin content in diabetic animals and those treated with YLE remains similar to the control group. Collagenases and gelatinases activities were significantly increased by diabetes in liver and kidney. While YLE treatment abrogates diabetes‐enhanced MMPs activities in liver. In diabetic rats, the liver shows signs of diffuse dilatation of the sinusoid veins and steatosis. However, the liver of diabetic rats treated with yellow lupine extract showed a normal histological aspect similar to controls. Diabetes causes hepatic and renal ECM turnover. YLE can be useful to partially improve tissue disorders induced by diabetes. Abstract : Lupinus luteus abrogate changes induced by diabetes in ECM turnover and at histological level. There is the first study to investigate effect of L. luteus on diabetes and on hepatic and renal ECM turnover.
