Objective
2
To investigate the effect of calycosin-mediated glucoprotein130/Janus kinase/signal transducer and activator of transcription factor (GP130/JAK/STAT) signaling pathway on oxidative injury of astrocytes in spinal cord.
Method
2
Astrocytes in rat spinal cord were isolated and identified by immunofluorescence detection of glial fibrillary acidic protein (GFAP). The cells were respectively pre-treated with 5, 10, 20 μmol·L
-1
calycosin for 12 h, and then 100 μmol·L
-1
H

O
2
(24 h) was added to induce oxidative injury. Cell counting kit-8 (CCK-8) assay was employed to detect cell proliferation and select the optimal concentration of calycosin. The following experimental groups were designed: control group, model group (100 μmol·L
-1
H

), calycosin group (20 μmol·L
-1
calycosin), calycosin + LY294002 group (20 μmol·L
-1
calycosin + 10 μmol·L
-1
LY294002), and calycosin + Stattic group (20 μmol·L
-1
calycosin + 3 μmol·L
-1
Stattic). CCK-8 assay and immunofluorescence method were used to detect the proliferation of cells and flow cytometry was applied to detect cell apoptosis and cycle. The protein expression of phosphorylated (p)-JAK2, p-STAT3, p-protein kinase B (Akt), GP130, and interleukin-6 (IL-6) was detected by Western blotting.
Result
2
Compared with the control group, the model group showed low proliferation activity and high apoptosis rate of cells (
P
<
0.05). Compared with the model group, calycosin (20 μmol·L
-1
) group displayed high proliferation activity and low apoptosis rate of cells (
P
<
0.05). Compared with calycosin (20 μmol·L
-1
) group, both phosphatidylinosirtol-3-kinases (PI3K) inhibitor LY294002 and STAT3 inhibitor Stattic significantly reduced the proliferation activity and increased the apoptosis rate of cells (
P
<
0.05). The protein expression of p-JAK2, p-STAT3, p-Akt, GP130, and IL-6 in the model group was higher than that in the control group (
P
<
0.05), and the expression of the above indicators was lower in each treatment group than in the model group
(P
<
0.05).
Conclusion
2
Calycosin can promote the proliferation and inhibit the apoptosis of astrocytes with oxidative injury by inhibiting the phosphorylation of PI3K/Akt pathway and JAK2/STAT3 pathway.
