Effect of bleomycin(BLM) on lysyl oxidase(LO) activity in conditioned media of culture HLF cells. Growth-arrested HLF cells in 0.3% FBS/phenol red-free DMEM were exposed to BLM at indicated doses for 24 h. The conditioned media were collected and assayed for LO activity. 0.5 mmol/L β-aminoproppionitrile (BAPN) was used as an internal control. Data shown are the mean±SD (n=3). ^bP<0.05, ^cP<0.01 compared with control.
