Huang et al. have demonstrated that DCP exerts anti-radiation fibrosis effects by inhibiting the activation of the Transforming Growth Factor beta 1/Small Mothers Against Decapentaplegic/Connective Tissue Growth Factor (TGF-β1/Smads/CTGF) signaling pathway (Huang et al., 2025). This evidence concerns the gene TGFB1 and radiation pneumonitis.
