Article Title: Inhibitory Effect of Mitoxantrone on Collagen Synthesis in Dermal Fibroblasts
doi: 10.5021/ad.2022.34.3.206
Figure Lengend Snippet: Effect of mitoxantrone on transforming growth factor-β (TGF-β)/SMAD signaling. (A) Fibroblasts were treated with mitoxantrone for 1 hour then stimulated with TGF-β for 1 hour. Phosphorylations of SMAD2 and SMAD3 were determined by Western blot. Mitoxantrone slightly inhibited TGF-β-induced phosphorylation of SMAD3. (B) The protein levels of collagen type I α1 chain (COL1A1) and collagen type I α2 chain (COL1A2) were determined by Western blot. Mitoxantrone weakly but significantly inhibited TGF-β-induced collagen synthesis. Actin beta (ACTB) was used as a loading control.
