Figure Lengend Snippet: The expression of PCK1 in renal tissue exhibited a negative correlation with the expression of inflammatory chemokines and fibrosis-related markers. Immunohistochemistry and quantification of TNF-α and IL-1β in human renal tissue (patients with IgAN, n = 79 and NC, n = 30). (B) Pearson correlation analysis of the relationship between PCK1 and TNF-α/IL-1β expression. Decreased PCK1 expression was linearly negatively correlated with TNF-α/IL-1β levels (r = -0.625/r = -0.607, p < 0.001); (C) Immunohistochemistry and quantification of TGF-β1, psmad3, α-SMA, FN, and col-IV in human renal tissue (patients with IgAN, n = 79 and NC, n = 30). (D) Pearson correlation analysis of the relationship between PCK1 and TGF-β1/psmad3/α-SMA/FN/col-IV expression. Decreased PCK1 expression was linearly negatively correlated with TGF-β1/psmad3/α-SMA/FN/col-IV levels (r = -0.505/r = -0.720/r = -0.613/r = -0.731/r = -0.668). Abbreviations: NC, normal control; TNF-α, tumor necrosis factor α; IL-1β, interleukin 1β; TGF-β1, transforming growth factor-β1; psmad3, Phosphorylated-smad3; α-SMA, α-smooth muscle actin; FN, fibronectin; col-IV, collagen-IV. *** p < 0.001.
