Assessment of cell viability following treatment with E₂, doxorubicin (Dox), or both in various cell lines.

Notes: (A) Cell viability and (B) count of MCF7 cultures treated with E₂ (20 nM), Dox (0.1, 0.5, or 1 μg), or E₂ (20 nM) + Dox (1 μg) for 3, 6, 24, or 48 hours. (C) Cell count in cultures of MDA-MB231, SKOV3 and HepG2 cultures separately treated with E₂ (20 nM), Dox (0.1, 0.5, or 1 μg), or E₂ (20 nM) + Dox (1 μg) for 3, 6, 24, or 48 hour. Data shown in A–C are means ± SD of three separate experiments.
