Figure 4From: Fractionated irradiation induced radio-resistant esophageal cancer EC109 cells seem to be more sensitive to chemotherapeutic drugsSensitivity of EC109 and EC109/R cells to cisplatin, 5-fluorouracil, doxorubicin, paclitaxel or etoposide. EC109 or EC109/R Cells were exposed to various concentrations of cisplatin, 5-fluorouracil, doxorubicin, paclitaxel or etoposide for 48 h, and then the viability was calculated using MTT assay. Each point represents the mean ± SD of triplicate experiments (p < 0.05).Back to article page
