ABSTRACT
OBJECTIVE:
To investigate the function and mechanism of CXC chemokine receptor 7 (CXCR7) in neuronal cells of ischemic stroke.METHODS:
The expression of CXCR7 in human neuroblastoma SH-SY5Y cells was interfered by small interfering RNA (si-RNA) technique. Oxygen-glucose deprivation/reoxygenation (OGD/R) injury model was constructed in SH-SY5Y cells. CXCR7 protein expression and cell cycle were detected by flow cytometry (FCM). The protein expression of CXCR7 and Akt signaling pathway was detected by Western blotting.RESULTS:
After 6 hours of OGD/R, the expression of CXCR7 was significantly decreased compared with OGD/R 0 hour (CXCR7/GAPDH 0.483±0.098 vs. 1.000±0.000 by Western blotting and 0.686±0.0524 vs. 1.000±0.000 by FCM, both P < 0.01), cell cycle arrest in G0/G1 phase (1.190±0.040 vs. 1.000±0.000, P < 0.01). After CXCR7 si-RNA interference with SH-SY5Y cells, OGD/R was constructed again for 6 hours. Compared with negative control group (si-NC group) under the same environment, the expression of CXCR7 and phosphorylated Akt (p-Akt) was significantly decreased (CXCR7/GAPDH 0.471±0.051 vs. 1.000±0.000, p-Akt/GAPDH 0.616±0.027 vs. 1.000±0.000, both P < 0.001) and cell cycle arrest in G0/G1 phase (1.105±0.033 vs. 1.000±0.000, P < 0.05).CONCLUSIONS:
The CXCR7 could regulate the cycle of neuronal cells in ischemic stroke through Akt signaling pathway, which has a protective effect on neuronal cells.
