Figure Lengend Snippet: BMP7 increases MMP2 expression and activity in SW1353 cells. ( A ) SW1353 cells (biological triplicates) were exposed to 1 nM BMP7 for 24 h and MMP2 mRNA expression was determined using RT-qPCR analysis. Data were normalized to cyclophillin expression and set relative to control conditions. ( B / C ) In parallel acquired samples with identical treatment (n = 3) MMP2 protein levels and activity in culture supernatant were measured using a MMP2 ELISA and MMP2 activity assay (relative to control condition). ( D ) OA-HACs (n = 18) were exposed to 1 nM BMP7 for 24 h after which MMP2 mRNA expression was measured by RT-qPCR. Data were normalized for cyclophilin mRNA levels and set relative to control conditions per patient. ( E ) SW1353 cells (biological quadruplicates) were pre-incubated with the selective MMP2 inhibitor OA-Hy (50 µM) for 24 h. MMP2 activity was determined and calculated relative to the control condition. ( F ) Collagen type I protein levels were detected in SW1353 cells (biological quintiplicates) by immunocytochemistry in control conditions and conditions exposed to MMP2 inhibitor OA-Hy (50 µM) with and without BMP7. Data were normalized for DNA content and set relative to control conditions. Statistical significance was determined using 2-tailed unpaired Student’s t-tests ( D per donor and as a group). Bars show the mean (± SEM). * P < 0.05, ** P < 0.01, *** P < 0.001 versus control conditions.

Article Snippet: SW1353 chondrosarcoma cells and OA HACs were treated with 1 nM BMP7 (R&D Systems, Minneapolis, MN, USA) for 24 h. Prior to BMP7 exposure, SW1353 cells were pre-incubated for 1 h with 50 μM selective MMP2 Inhibitor I (OA-Hy SantaCruz Biotechnology, Dallas, TX, USA).

Article Title: BMP7 reduces the fibrocartilage chondrocyte phenotype

doi: 10.1038/s41598-021-99096-0

Figure Lengend Snippet: Proposed molecular interactions by which BMP7 attenuates the fibrocartilage chondrocyte phenotype. The potential molecular pathway by which BMP7 attenuates the fibrocartilage chondrocyte phenotype as proposed in this study. Upon BMP7 exposure, chondrocytic cells demonstrate reduced SMAD3 signaling, interfering with PAI1 expression and activity. In addition, following BMP7 exposure, MMP2 expression and activity is increased via PAI1 and MT1-MMP, resulting in a reduced fibrocartilage chondrocyte phenotype. BMP7’s mode of action to reduce chondrocyte fibrosis is MMP2-dependent. Dashed lines: interactions which have been found in organ-fibrosis (with corresponding references), but have not been demonstrated directly in the present study. Solid lines: interactions directly demonstrated in the present study (regarding chondrocyte fibrosis).

doi: 10.1002/cam4.1438

Figure Lengend Snippet: (A) Cell migration assay was carried out using PPAR γ knockdown cell lines, OUMS 27 sh PPAR and SW 1353 sh PPAR , and the control cell lines, OUMS 27 sh NTC and SW 1353 sh NTC with or without the treatment of zaltoprofen. A selective inhibitor of MMP 2, ARP 100, was used at 25 μ mol/L. Scale bar = 100 μ m. (B, C) The fielded wound area (%) was calculated in OUMS 27 (B) and SW 1353 cells (C). Values represented as the mean ± SEM . Asterisks denote a statistically significant difference (* P < 0.05 and ** P < 0.01).
