The induction of Hsp70 production in arsenite-stressed 030D cells. 030D cells were either left untreated, or exposed to the indicated concentrations of arsenite or LPS (1 µg/mL) for 16 h. (A) The percentages of Hsp70-positive cells detected by flow cytometry using FITC-labeled Hsp70 specific antibody. (B) Mean fluorescence intensities (MFI) of Hsp70 positive cells. (C) The mRNA expression of Hsp70 was measured by qPCR. Data are shown as the mean ± SD and are representative of three independent experiments. * p < 0.05, ** p < 0.01, vs. control group.
