ABSTRACT
Objective To explore the effects of BSA on hypoxia inducible factor/hypoxia response element (HIF/HRE) transcription activity in rat tubular epithelial cells (NRK-52E) with HRE-Luc reporter plasmid.Methods Luciferin activity of NRK-52E cells incubated by a medium contained BSA in varying concentration (0,5,10,20 mg/ml) and stimulus duration (24,48,72 h) was detected by dual luciferase detecting system based on HRE-Luc reporter plasmid and HIF-1 α expression was detected by Western blotting.Results HIF/HRE transcription activity of NRK-52E cells was increased in BSA incubation group (10 mg/ml,48 h) compared with blank control (BSA 0 mg/ml,48 h) [(2.59±0.35)vs (1.03±0.09),P=0.000].HIF-1α expression of NRK-52E cells was increased in BSA incubation group (20 mg/ml,48 h) compared with blank control (BSA 0 mg/ml,24 h) [(0.052±0.010) vs (0.014±0.003),P=0.000].Conclusion Albumin can increase HIF/HRE transcription activity of TEC.
