Abstract

The aim of this study was to evaluate the effects of M2000, a novel non-steroidal anti-inflammatory drug (NSAID) with immunosuppressive property and without gastro-nephrotoxicitic effects on matrix metalloproteinases (MMP)-2 and (MMP)-9 in phorbol myristate acetate (PMA)-differentiated THP-1 cells. Gene expression and activity of MMP-2 and MMP-9 are inhibited respectively by the tissue inhibitor of matrix metalloproteinase (TIMP)-2 and (TIMP)-1 and are induced by extracellular matrix metalloproteinase inducer (CD147/EMMPRIN). In this study, real-time quantitative reverse transcription polymerase chain reaction (RT-PCR) was used to determine gene expression of MMP-2, MMP-9, TIMP-1, and TIMP-2. Flow cytometry and zymography were applied to determine cellular surface expression of CD147 and activity of MMP-2 and MMP-9, respectively. Our results showed that treatment of THP-1 cells with high concentration (25 μg/mL) of M2000 significantly decreased the cellular surface expression of CD147 (p<0.05) and the gene expression of MMP-2, MMP-9 and TIMP-1 (p<0.05), and inhibited the gelatinolytic activity of MMP-2 and MMP-9 (p<0.05). According to our results, M2000 can reduce inflammation through inhibition of the cellular surface expression of CD147 and decrease the gene expression and gelatinolytic activity of MMP-2 and MMP-9 in PMA-differentiated THP-1 cells. © Copyright Autumn 2017, Iran J Allergy Asthma Immunol.
