Cell survival assays. (A) The effects of estrogen and progesterone cotreatment on cisplatin sensitivity of MCF-7 cells. MCF-7 cells were cotreated with 2 × 10−7 M estrogen, 2 × 10−7 M progesterone, or both hormones with cisplatin for 4 h. (B) The effects of hormones on cisplatin sensitivity of Evsa-T cells. Evsa-T cells were pretreated with 10−7 M estrogen or 10−6 M progesterone for 2 h before a 4-h cisplatin treatment. (C) The effects of 10−7 M estrogen on cisplatin sensitivity of HeLa cells.
