Fig. 1. Viability of renal cells with NaAsO2 treatment. (A) HEK293 cells were treated with various concentrations of NaAsO2 for 24 h and cell viability was determined by the MTT assay. (B) HEK293 cells were treated with 20 μM of NaAsO2 for various time intervals. Cell viability was determined by the MTT assay. Each value represents a mean ± standard deviation of three independent samples. Asterisk indicates the significant difference as compared to that of the untreated cells. *p < 0.05.
