This study demonstrated the therapeutic effects of BSJPQYF in aplastic anemia, which could alleviate myelosuppression through inhibiting the expression of the PI3K/AKT/NF-kappa B signaling pathway.
Bushen Jianpi Quyu Formula (BSJPQYF), an experienced formula, has been used to treat aplastic anemia (AA) more than three decades. To determinate the effect of BSJPQYF on AA, we constructed an immune-mediated AA mouse model. All mice were divided into four groups: control, model, low dose (0.85 g/mL), and high dose (1.7 g/mL BSJPQYF) group. They were administered with different concentrations of BSJPQYF or normal saline for 14 days. Besides, components of BSJPQYF were analyzed by electrospray ionization and mass spectrometry (ESI-MS). Subsequently, mouse peripheral blood and femurs were collected, and bone marrow mesenchymal stem cells (BMSCs) were isolated by fluorescence-activated cell sorting (FACS). Among them, tumor necrosis factor-alpha (TNF-alpha), transforming growth factor-beta (TGF-beta), and interferon-gamma (IFN-gamma) were measured by ELISA assay, PI3K, AKT, p-AKT, NF-kappa B, p-NF-kappa B, TNF-alpha, and cleaved caspase-3 proteins were detected by western blot. Compared with standard compounds, we identified three compounds of BSJPQYF, namely, icariin, kaempferol and tanshinone iia, as potentially effective compounds for the treatment of AA. Through an in vivo study, we found the administration of BSJPQYF in high dose for 14 days could significantly increase peripheral blood count and bone marrow (BM) cells, meanwhile decrease TNF-alpha, TGF-beta, and IFN-gamma levels. Besides, it could suppress the protein expression of PI3K and the phosphorylation of AKT and NF-kappa B to restrict the protein expression of TNF-alpha, eventually reduce the protein expression of cleaved caspase-3. This study demonstrated the therapeutic effects of BSJPQYF in AA, which could alleviate myelosuppression through inhibiting the expression of the PI3K/AKT/NF-kappa B signaling pathway.
