doi: 10.3390/antiox13101199
Figure Lengend Snippet: NOX5 enhances MMP-10 promoter activity via the JNK pathway and a functional AP-1 site: ( A ) MMP-10 promoter activity of tHMock and tHNOX5 cell lines at baseline and stimulated with 0.25 μM Ang II ( n = 6). ( B ) MMP-10 promoter activity of tHMock and tHNOX5 cell lines after 24 h of incubation with 5 μM 219138-24-6 (p38 MAPK inhibitor, ip38), PD98059 (MEK/ERK inhibitor, iERK), or JNK-IN-8 (JNK inhibitor, iJNK) ( n = 6). ( C ) Schematic representation of MMP-10 promoter constructions used and quantification of MMP-10 promoter activity of tHMock and tHNOX5 cell lines transfected with MMP-10 promoter constructions ( n = 6). CREB: cAMP response element binding protein (CREB) putative union site. AP-1: activator protein-1 (AP-1) putative union site. Crosses indicate site-directed mutations in the putative union sites. tHMock: stable cell line transfected with pcDNA3.2-Mock. tHNOX5: stable cell line transfected with pcDNA3.2-NOX5. ns: not significant differences, * p < 0.05 vs. tHMock Ctrl, *** p < 0.001, **** p < 0.0001, # p < 0.05 vs. tHNOX5 Ctrl cells. Data are presented as median and IQR or as mean ± SEM.
Article Snippet: The p38 MAPK inhibitor (ab145872, Abcam ® , Waltham, MA, USA), JNK MAPK inhibitor (JNK-IN-8, SML1246, Sigma Aldrich), and ERK MAPK inhibitor (PD98059, 9900S, Cell Signaling Technology, Danvers, MA, USA) were used at final concentrations of 5 μM in the cell medium.
