Abstract:
OBJECTIVE:To explore the hematopoiesis protection effect of Danggui Buxue Tang (DBT) and its main components Angelica polysaccharide (APS) and Astragalus polysaccharide (ASPS) on myelosuppression mice, and the mechanism of anti-apoptosis of Meg-01 cells.
METHODS:Mice were radiated with 4 Gy of 137Csγ ray to establish the model of radiation-induced myelosuppression. DBT, APS or ASPS (10 mg/kg) were injected into irradiated mice. Peripheral blood cell counts were performed on mice before radiation (day 0) and day 7, 14 and 21 after radiation. On the 21st day, poor plasma platelets were collected from mice to detect TPO concentration and then the mice were sacrificed. The femoral bone marrow cells were cultured for colony cell forming units (CFU). Meg-01 cells were cultured without FBS for 24 h to induce apoptosis, and then treated with DBT/APS/ASPS for 72 h. Flow cytometry (FCM) was used to detect early apoptosis (Annexin V), mitochondrial membrane potential (JC-1) and the expression of Caspase-3 to analyze the effect of DBT/APS/ASPS on cell apoptosis.
RESULTS:DBT can stimulate the recovery of white blood cells (WBC), red blood cells (RBC) and platelets (PLT) of myelosuppression mice, especially for WBC and PLT (P<0.01, P<0.05). Compared with the control group, the number of BFU-E, CFU-MK and CFU-GM increased after adding DBT (BFU-E & CFU-GM: P<0.05； CFU-MK: P<0.01). The effect of DBT on blood TPO concentration in mice was not obvious (P=0.89). RBC, WBC and PLT were increased in APS group compared with control group (P<0.05). WBC increased after the treatment of ASPS (P<0.05). APS stimulated the formation of CFU-F, CFU-MK and CFU-GM (P<0.05). Only CFU-GM increased in ASPS group(P<0.05). Besides, DBT decreased the apoptosis of Meg-01 cells (P<0.05). The early apoptosis rate and total death rate in APS (100 μg/ml) group were lower than that of control group (P<0.01, P<0.05). The early apoptosis rate of ASPS (100 μg/ml) group was lower than that of control group (P<0.05). JC-1 and Caspase-3 showed that APS (100 μg/ml) significantly reduced apoptosis rate (P<0.01, P<0.05).
CONCLUSION:DBT has protective effect on hematopoietic system, especially WBC and PLT, and has anti-apoptotic effect on Meg-01. It was found that the above effects of DBT were mainly caused by APS, and its anti-apoptosis mechanism was carried out mainly through JC-1 and Caspase-3 pathways.
