Hepatoprotective role of bis-demethoxy curcumin analog on the expression of matrix metalloproteinase induced by alcohol and polyunsaturated fatty acid in rats.

Liver fibrosis is one of the major health problems worldwide. Chronic alcohol abuse is one of the main causes of fibrosis. Ingestion of polyunsaturated fatty acids (PUFA) along with alcohol further aggravates the toxicity of alcohol. Fibrosis results due to increased deposition of extra cellular matrix (ECM). The degree of abnormal ECM degradation depends on the ratio of active matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs). The present work studied the influence of bis-desmethoxy curcumin analog (BDMC-A) on the expression of MMPs and TIMPs during alcohol and DeltaPUFA induced liver toxicity. Male albino Wistar rats were used for the study. The MMP expression was found to be increased in alcohol as well as DeltaPUFA treated rats and decreased in alcohol + DeltaPUFA treated rats. The levels of TIMPs and the collagen were increased in alcohol, DeltaPUFA, and alcohol + DeltaPUFA groups. Administration of BDMC-A significantly decreased the levels of collagen and TIMPs; and positively modulated the expression of MMPs. From this study, it is concluded that BDMC-A influences MMPs, TIMPs expression, and acts as an efficient anti-fibrotic agent.
