Figure Lengend Snippet: The role of EZH2 in regulating collagen and α-SMA expression in HSF. EZH2 mRNA ( a ) and protein expression ( b ) were measured using qRT-PCR and western blot analyses, respectively, in siRNA-EZH2 and siRNA-control transfected HSF. ( c ) RNA sequencing profiling of HSF in which EZH2 was knocked down. Shades of red represent increased gene expression; shades of blue represent decreased gene expression.

Figure Lengend Snippet: MPs and rhEPO attenuate TGF-β1-induced EMT in MDCK cells. A Morphological changes in TGF-β1-treated MDCK cells observed by phase contrast microscopy. Compared to control MDCK cells (a), TGF-β1 treatment changed MDCK cell morphology from cuboidal to an elongated spindle-like shape (b). These morphological changes were reversed by co-treatment with MOCK-MPs (c), hEPO-MPs (d), and rhEPO (e). Fluorescence microscopy of red fluorescent CellTracker™-labeled MP incorporation into MDCK cells (m, n, r, s). Blue staining represents nuclear counterstaining with DAPI (f–j, p–t). B RT-PCR of hEPO mRNA expression in MDCK cells co-treated with hEPO-MPs, demonstrating that MPs mediated the horizontal transfer of hEPO mRNA into target MDCK cells.

Figure Lengend Snippet: Effect of MPs or rhEPO on EMT markers in MDCK cells. A – C qRT-PCR of E-cadherin, vimentin, and α-SMA mRNA in MDCK cells co-treated with TGF-β1 and MPs or rhEPO. Compared to vehicle-treated MDCK cells, TGF-β1 treatment significantly decreased E-cadherin and increased vimentin and α-SMA mRNA expression. MOCK-MPs, hEPO-MPs, and rhEPO reversed these changes in E-cadherin, vimentin, and α-SMA mRNA expression. D Western blotting for E-cadherin, α-SMA, and fibronectin protein levels in MDCK cells co-treated with TGF-β1 and MPs or rhEPO. Compared to vehicle-treated MDCK cells, TGF-β1 significantly decreased E-cadherin expression ( E ) and increased α-SMA and fibronectin expression ( F , G ). Co-treatment with MOCK-MPs, hEPO-MPs, and rhEPO significantly ameliorated these changes induced by TGF-β1. Western blotting data were normalized to GAPDH. Molecular weights are shown in kDa.

Figure Lengend Snippet: Figure 2. During anti-GBM nephritis, the lack of TSP2 neither leads to compensatory upregulation of TSP1 nor influences TGF- activation. During anti-GBM nephritis, TSP1 was de- tected predominantly in cells of Bowman’s capsule, in the periglomerular tubulointerstitium (A), and in some cases within the glomerulus (B), as assessed by immunohistochem- istry (brown staining). Semiquantitative evaluation of cortical TSP1 revealed peak expression at approximately days 14 to 21 in both groups (C). Phosphorylated Smad 2/3, as an indirect indicator of activated TGF-, was evaluated by immunohisto- chemistry followed by computer-assisted analysis using Meta- Vue software (D).
