ABSTRACT

AIM:

To study the protective effects of ginsenoside Rg1 on HL-7702 cells injury induce by oleic acid (OA), and investigate its role in aldolase/AMPK/PINK1 signalling.

METHODS:

HL-7702 cells were cultured in vitro and divided into five groups control group (C), oleic acid group (OA), OA+ginsenoside (Rg1) group, OA+compound C (CC) group, and OA+CC+Rg1 group. The viability of HL-7702 cells was determined by CCK8 assay and Hoechst staining. The apoptosis and mitochondrial membrane potentials of HL-7702 cells were measured using flow cytometry. ATP content in HL-7702 cells was observed. Western blot was used to detect the expression levels of Cleaved caspase-3, PINK1, MFN2, Aldolase and p-AMPK in HL-7702 cells.

RESULTS:

Compared with C group, the viability of cells in OA group was significantly decreased (P<0.05), the apoptotic rate and Cleaved caspase-3 expression were greatly increased (P<0.05), ATP level, mitochondrial membrane potentials (TMRE) and PINK1 expression were significantly decreased (P<0.05). Compared with OA group, the viability of cells in OA+Rg1 group was significantly increased (P<0.05), the apoptotic rate and Cleaved caspase-3 expression were greatly decreased (P<0.05), ATP level, mitochondrial membrane potentials (TMRE) and PINK1 expression were significantly increased (P<0.05). Compared with OA+Rg1 group, the viability of cells and p-AMPK expression level in OA+CC+Rg1 group was significantly decreased (P<0.05). Reducing the expression of aldolase in cells inhibited Rg1?s actions on PINK1 and p-AMPK and cell viability.

CONCLUSION:

Ginsenoside Rg1 can improve the injury of HL-7702 cells via regulating aldolase/AMPK/PINK1 signaling pathway.
