ABSTRACT
AIM: To investigate DNA damage and cell stress (heat shock protein 70 expression) in human bronchi smooth muscle cells by cigarette smoke extract (CSE) in vitro. METHODS: 30 mL smog was dissolved in 1 mL culture medium as stock solution of CSE. Human bronchi smooth muscle cells were cultured 3 hours with 1∶16, 1∶10, 1∶8, 1∶6 and 1∶4 of CSE. The DNA damage and HSP70 expression were determined by single cell gel assay (comet assay) and Western blot, respectively. RESULTS: Associated with rising CSE concentration, DNA damage aggravated. Compared with the untreated group, except 1∶16 of CSE, the level of DNA damage was significantly different (P
