Isoflavone Attenuates the Caspase-1 and Caspase-3 Level in Cell Model of Parkinsonism

Abstract EN

The study has investigated the effect of isoflavone attenuates the caspase-1 and caspase-3 level in cell model of Parkinsonism.

The subjects were PC12 cells.

They were randomly divided into six groups: control, MPP+ (250 μmol/L), isoflavone (10 μM), isoflavone (10 μM) + MPP+ (250 μmol/L), Z-YVAD-CHO (10 nM) + MPP+ group, and Z-DEVD-CHO (10 nM) + MPP+ group.

Cell viability was measured by MTT methods; the content of tyrosine hydroxylase was measured by immunocytochemistry method of avidinbiotin peroxidase complex; apoptosis ratio was measured by flow cytometry.

The results showed that cell viability in the MPP+ group was lower than in all other five groups.

There was no difference in cell viability between isoflavone + MPP+ and control group.

Optical density of TH positive cells in isoflavone group was higher than in control, isoflavone + MPP+, and MPP+ only groups.

The apoptosis ratio in the isoflavone + MPP+ group and control group and the Z-YVAD-CHO + MPP+ and Z-DEVD-CHO + MPP+ group was similar, which was lower than in the MPP+ group.

The lowest apoptosis ratio was found in the isoflavone only group.
