Figure Lengend Snippet: (A) Schematic graph illustrating the timeline for the culture and TGF-β1 treatment of dcSSc-isolated fibroblasts, matched healthy-isolated fibroblasts, and Normal Human Dermal (NHD) fibroblast cells. (B) RUNX1 expression rate in samples treated with TGF-β1 (in red) vs. control for the 24 hours after exposure. (C) Volcano plot of differentially expressed analysis of the two SSc-isolated fibroblast lines at 12 hours after exposure vs. the baseline. (D) The pathway analysis of Reactome gene sets shows the biological pathways and processes that are significantly represented within top DEG genes of SSc-isolated fibroblast lines 12 hours after TGF-β1 treatment vs. the baseline. (E) Fold change expression of TGF-β1 and CBFB in TGF-β1-induced SSc fibroblasts treated with Ro5-3335 ( RUNX1 inhibitor), compared to control. (F) Proliferation curve of NHD fibroblasts in the presence and absence of Ro5-3335. (G–H) The 3D collagen contraction assays, fixed (G) and floating ( H ) models, of NHD fibroblasts treated with Ro5-3335. SIS3 (SMAD3 inhibitor) was used as positive control that significantly eliminates the contraction ability of fibroblasts. (Student’s t-test P- value: **0.001–0.01, ****<0.0001 in GraphPad Prism v9)
Article Snippet: We analyzed a DNA microarray dataset previously generated by our lab, consisting of two independent SSc fibroblasts, one healthy control fibroblast isolated in parallel, and one normal human dermal (NHD) fibroblast cell lines obtained from ATCC.
