Fig. 2From: Phenformin alone or combined with gefitinib inhibits bladder cancer via AMPK and EGFR pathwaysEffect of gefitinib on bladder cancer cell proliferation. Viability of T24, UMUC3 and MB49 cells was assessed after 48-h exposure to gefitinib at concentrations ranging from 0 to 80 µmol/L using a tetrazolium-based assay. Results are the mean ± SD of three independent experimentsBack to article page
