The effect of hypoxia on drug sensitivity in HMM cells. MTT assay. The sensitivity to cisplatin was decreased in HMM cells under hypoxia for 24 h (a) and 48 h (b), compared to the sensitivity of those in normoxia. * indicates a significant difference compared with the corresponding normoxic cisplatin-treated control. *P value < 0.05, **P value < 0.01, as calculated by Student’s t-test
