Figure Legend Snippet: FIGURE 5 PAI-1 induced p53 upregulation is critical for the subsequent maladaptive response. A, Western blot assessments for total and p-p53 protein levels between CMV-Con and CMV-PAI-1 populations. B-C, Histograms depicting the relative expression of p53 levels (mean ± SD) for three independent studies, n = 3. D-G, Lysates of CMV-PAI-1+Con-shRNA and CMV-PAI-1+p53-shRNA double transductants are immunoblotted for p53 (D, E; P < .001), p21 (D, F; P < .01), p-H3 (D, G; P < .01), fibronectin (H, I; P < .01), collagen-1 (H, J; P < .01). Histograms in (E-G) and (I-J) depict the relative expression (mean ± SD) for indicated proteins from the immunoblots in (D) and (H), shown as biological triplicates for three independent studies (n = 3). K, Confluent monolayers of CMV-PAI-1+Con-shRNA and CMV-PAI-1+p53- shRNA HK2 cultures are serum-starved for 6 days. Phase contrast and crystal violet images are taken on day 0 and day 6 to assess cell monolayer detachment. Scale bar = 400 µm. L, Western blot analysis for FAK and p-ERK1/2 protein levels between CMV-Con and CMV-PAI-1 cultures, with ERK2 serving as a loading control, (n = 3). *P < .05, **P < .01, ***P < .001
Techniques Used: Western Blot, Expressing, shRNA, Control
Figure Legend Snippet: FIGURE 6 Klotho downregulation consequent to PAI-1 induction contributes to epithelial dysfunction. A-C, Immunoblot analysis of CMV- Con and CMV-PAI-1 cell lysates for PAI-1 (A, B; P < .001) and klotho (A, C; P < .01) expression. Histograms in (B-C) represent the relative expression of the indicated proteins as (mean ± SD) for three independent studies (n = 3). D-I, Protein extracts of CMV-PAI-1+CMV-Con and CMV-PAI-1+CMV-Klotho double transgenic cultures are immunoblotted for klotho (D, E; P < .001), CCN2 (D, F; P < .001), p21 (D, G; P < .01), p53 (D, H; P < .001), p-SMAD3 (D, I; P < .01). GAPDH serves as loading control. Histograms in (E-I) depict the relative levels (mean ± SD) of the indicated proteins for three separate experiments (n = 3). **P < .01, ***P < .001
Techniques Used: Western Blot, Expressing, Transgenic Assay, Control
Figure Legend Snippet: FIGURE 8 Dysfunction driven by PAI-1 overexpression is independent of TGF-β1 ligand synthesis or release. A, ELISA analysis for active TGF-β1 ligand concentrations in the conditioned media isolated from serum-starved CMV-Con and CMV-PAI-1 cultures. n = 3. B-D, Cytokine protein array analysis of CMV-Con and CMV-PAI-1 conditioned media for active TGF-β1 (B), TGF-β2 (C), and TGF-β3 (D). Graphs depict the relative levels of secreted ligands (mean ± SD), n = 3. E, Immunoblot comparison of fibrotic responses in the cellular lysates of TGF-β1 stimulated or unstimulated CMV-Con and untreated CMV-PAI-1 culture extracted in parallel. F, CMV-Con HK2 cells pretreated with 20 μg/mL of TGF-β1 neutralizing antibody or 20 μg/mL IgY control antisera are stimulated with 2 ng/mL TGF-β1. Cells are harvested after 24 hours and expression of p-SMAD3, fibronectin and E-cadherin are analyzed by western blot. n = 3. G, Equally seeded CMV-PAI-1 HK2s are treated with various concentrations of TGF-β1 neutralizing antibody (0, 20, 40, 60 μg/mL) or 60 μg/mL IgY control antisera for 24 hours prior to western blot analysis of extracts for p-SMAD3, fibronectin, collagen-1, vimentin, p53 and p21, with GAPDH is serving as a loading marker. n = 3, *P < .05, **P < .01, ***P < .001, n.s., not significant. H, Western blot analysis of cell lysate extracts from CMV-PAI-1+Con shRNA and CMV-PAI-1+TGF-β1 shRNA HK2 cells for the indicated fibrotic markers. Cytokine protein array analysis of whole cell lysates (I) and conditioned media (J) used to validate TGF-β1 knockdown

Figure Legend Snippet: FIGURE 9 Model. PAI-1 upregulation leads to downregulation of klotho, upregulation of p53, and induction of TGF-β1 receptor signaling independent of the TGF-β1 ligand, resulting in expression and secretion of fibrotic markers, downregulation of E-cadherin and upregulation of vimentin, leading to dedifferentiation, and upregulation of p21, p-H3, causing G2/M cell cycle arrest and a propensity to cell death, collectively establishing a role for PAI-1 in tubular epithelial dysfunction. Klotho regulates both p53 and SMAD3 signaling, promoting PAI-1-mediated tubular maladaptive responses
