Figure Lengend Snippet: Activation of Fn14 facilitates fibroblast senescence. A-D , primary fibroblasts were treated with rTWEAK (100 ng/mL) for 48 h. Cell samples were harvested after 48 h. Western blot for P53, P21, and γ-H2AX proteins expression ( n = 3). E , the expressions of Il6 , Tgfb1 , Mcp1 , Mmp2 , Mmp9 , and Mmp12 mRNA in primary fibroblasts were detected by Real-time PCR ( n = 3). F , SA-β-gal staining was performed 48 h after rTWEAK treatment, scale bar = 50 μm. G , Comet assay in rTWEAK-treated primary fibroblasts, scale bar = 10 μm. H , Immunofluorescence for Ki67 protein expression in rTWEAK-treated primary fibroblasts, scale bar = 50 μm. I-J , Effects of Fn14 activation on the cell cycle were detected by flow cytometry. * P < 0.05, ** P < 0.01, and *** P < 0.001

Figure Lengend Snippet: Inhibition of the cGAS-STING signaling suppresses the senescence of rTWEAK-treated fibroblasts. A-B , primary fibroblasts were treated with rTWEAK (100 ng/mL) for 48 h after RU.521 (10 µM) intervention for 30 min. Western blot was conducted to examine the expression levels of cGAS, STING, p-TBK1 Ser172 , and p-IRF3 Ser396 ( n = 3). C-D , The senescence-related protein levels of P53, P21, P16, and γ-H2AX were assessed by Western blot ( n = 3). E , Immunofluorescence of Ki67 protein expression in rTWEAK-treated primary fibroblasts with RU.521, scale bar = 50 μm. F , Comet assay in rTWEAK-treated primary fibroblasts with RU.521, scale bar = 10 μm. G , Real-time PCR for Il-6 , Tgf-β , Mcp1 , Mmp2 , Mmp9 , and Mmp12 mRNA expression ( n = 3). H , SA-β-gal staining was performed 48 h after rTWEAK treatment, scale bar = 50 μm. * P < 0.05, ** P < 0.01, and *** P < 0.001
