Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 3, March 2026.In 2D culture, the cirsimarin (i) decreased cell viability in both assays, (ii) induced apoptosis, (iii) reduced clonogenicity, (iv) prevented cell migration, (v) induced DNA damage, and (vi) negatively modulated gene expression. In the 3D model, reductions in spheroid viability, area, and cell migration were also observed.
