Figure 1. Dex induces chemotherapeutic resistance in the HCC1937and HCC1806triple-negative breast cancer cell lines.

HCC1937or HCC1806 cells were seeded in 48-well plates at 1.0×10⁴ or 1.5×10⁴ cells/well and treated with the chemotherapeutic drugs docetaxel A, C. and cisplatin B, D. at the indicated concentrations with or without Dex for 48 h. Cell viability was measured using the SRB assay. *, P<0.05; **, P<0.01.
