Figure Lengend Snippet: Immunohistochemical analysis of collagen I and III, fibronectin, and elastin in ethyl pyruvate-treated keloid spheroids ( n = 3). ( A ) Representative images of collagen I and III, fibronectin, and elastin IHC staining of keloid spheroids treated with ethyl pyruvate (10, 20, and 40 mM). ( B ) Semi-quantification of protein expression is shown. Collagen I and III, fibronectin, and elastin were significantly decreased in keloid spheroids following ethyl pyruvate application. Asterisks (*) over each column signify a statistically significant difference compared to the control (0 mM, white bar) group (* p < 0.05). ( C ) Reduction in collagen I protein expression can be seen with western blot analysis.
Article Snippet: For IHC staining, the keloid spheroid sections were incubated overnight at 4 °C with primary antibodies including mouse anti-HMGB1 (Abcam), mouse anti-AKT (Abcam), mouse anti-ERK1/2 (Abcam), mouse anti-collagen type I (Abcam), mouse anti-collagen type III (Sigma-Aldrich), mouse anti-elastin (Sigma-Aldrich), and mouse anti-fibronectin (Santa Cruz Biotechnology).
