Chrysin downregulates the expression of ADAMTS-4 in foam cells.

ABSTRACT

BACKGROUND: Chrysin, a polyphenolic compound, possesses antioxidant and anti-inflammatory properties. In this study, we investigated the effect of chrysin on the expression of A disintegrin and metalloproteinase with thrombospondin motifs-4 (ADAMTS-4), a protease enzyme involved in degrading extracellular matrix associated with atherosclerosis. METHODS AND RESULTS: We have studied the cell viability by MTT assay and foam cell formation by oil red O staining. The mRNA and protein expression of ADAMTS-4 was studied using quantitative polymerase chain reaction (qPCR) and Western blotting, respectively. Our study showed that chrysin significantly downregulates the expression of ADAMTS-4 in foam cells. CONCLUSION: Chrysin's ability to downregulate the expression of ADAMTS-4, a protease involved in degrading the extracellular matrix, bestows upon it a new therapeutic potential for managing atherosclerosis.
