HT-29 cell viability, 48 h.

Ht-29 cells were treated with increasing concentrations of oxaliplatin (1–300 µM) in the presence or in the absence of 10 µM rosiglitazone. Incubation was allowed for 48 h. Cell viability was measured by MTT assay. Control condition was arbitrarily set as 100% and values are expressed as the mean ± S.E.M. of three experiments. *P<0.05 and **P<0.01 in comparison to control (oxaliplatin 0 µM).
