In ZR751 cells (ERα+/PR+/HER2−), a greater reduction in proliferation after individual or combined treatments was observed when the CIN increased, but did not exceed 67% (increased from 50% in untreated cells to 67% after treatments) (Figure 3 and Supplementary Table S2). This evidence concerns the gene PGR and cervical squamous intraepithelial neoplasia.
