OBJECTIVE To investigate the protective role of inducible heat shock protein 70 (Hsp70) against damage induced by formaldehyde. METHODS Human bronchial epithelium (HBE) cells were transfected with plasmid harboring hsp70 gene to increase the protein expression level. HBE cells transfected with pcDNA3.1 plasmid were used as transfection control and HBE(More)
OBJECTIVE To investigate the expression of the Hsp27 and Hsp70 in A549 cells treated with heat and BPDE. METHODS A549 cells cultured in vitro were divided into heat stress group and BPDE group. Cells cultured at 37 degrees C used as control. The heat stress group was exposed to heat at different temperature (39 degrees C, 42 degrees C and 43 degrees C)(More)
