| Abstract: | Objective To study the effect of different concentrations crocetin on HERG potassium channels protein expression.Methods Western Blotting,Immunofluorescence chemical staining method and laser confocal microsopy were used to detect the expression of HERG channel in the HERG-HEK cells with the influence of different concentrations of crocetin.Results Different concentrations of crocetin(1.0,3.0,10.0 and 30.0μM)were not significantly affected the expression of HERG potassium channels protein.Conclusions Crocetin had not significantly impact on the expression of HERG potassium channels protein,which provided a theoretical support for the safety of crocetin involving anti-arrhythmic mechanism as the herb as a Traditional Chinese Medicine used in clinical practice. |
