1.Novel synergic antidiabetic effects of Astragalus polysaccharides combined with Crataegus flavonoids via improvement of islet function and li
Cui K1, Zhang S2, Jiang X1, Xie W1. Mol Med Rep. 2016 Apr 15. doi: 10.3892/mmr.2016.5140. [Epub ahead of print]
The present study investigated the synergic effects and potential mechanisms of action of Astragalus polysaccharides (APS) combined with Crataegus flavonoids (CF) in the treatment of type 1 diabetes. Diabetes was induced by intraperitoneal injection of 100 mg/kg streptozotocin in mice. Normal and untreated diabetic control mice were used, and CF‑treated (200 mg/kg/day), APS‑treated (200 mg/kg/day), APS + CF (AC)‑treated (200 mg/kg/day of each) and metformin‑treated (200 mg/kg/day) diabetic mice were orally administrated the appropriate therapeutic agent for 4 weeks. The results demonstrated that AC treatment significantly reduced the fasting blood glucose, food and water intake in the diabetic mice. The AC group demonstrated increased serum insulin levels and islet cell function was restored. Furthermore, the AC‑treated mice demonstrated significant increases in the protein expression levels of pancreatic and duodenal homeobox‑1 and phosphorylated adenosine 5'‑monophosphate‑activated protein kinase in the pancreatic and liver tissue samples, respectively.
2.Astragalus polysaccharide upregulates hepcidin and reduces iron overload in mice via activation of p38 mitogen-activated protein kinase.
Ren F1, Qian XH2, Qian XL3. Biochem Biophys Res Commun. 2016 Mar 25;472(1):163-8. doi: 10.1016/j.bbrc.2016.02.088. Epub 2016 Feb 23.
Thalassemia is a genetic disease characterized by iron overload which is a major detrimental factor contributing to mortality and organ damage. The hepcidin secreted by liver plays an essential role in orchestrating iron metabolism. Lowering iron load in thalassemia patients by means of increasing hepcidin might be a therapeutic strategy. In this study, we first found that astragalus polysaccharide (APS) significantly increased hepcidin expression in HepG2 and L-02 cell lines originating from hepatocytes and mice liver, respectively. Following treatment with APS, the iron concentrations in serum, liver, spleen, and heart were significantly reduced in comparison to saline treated control mice. In further experiments, upregulation of interleukin-6 (IL-6) and enhanced p38 MAPK phosphorylation were detected in APS treated cells and mice, and as documented in previous studies, IL-6 and P38 MAPK phosphorylation are involved in the regulation of hepcidin expression.
3.Astragalus membranaceus: A Review of its Protection Against Inflammation and Gastrointestinal Cancers.
Auyeung KK1, Han QB2, Ko JK1. Am J Chin Med. 2016 Feb;44(1):1-22. doi: 10.1142/S0192415X16500014.
Astragalus membranaceus is a major medicinal herb commonly used in many herbal formulations in the practice of traditional Chinese medicine (TCM) to treat a wide variety of diseases and body disorders. Among its diversified clinical applications, the potential use of this herb and its chemical constituents in treatments of inflammatory diseases and cancers has been actively investigated in recent years. Astragalus-based treatments have demonstrated significant amelioration of the toxicity induced by other concurrently administered orthodox drugs (e.g., immunosuppressants and cancer chemotherapeutics). The major components of Astragalus membranaceus are polysaccharides, flavonoids, and saponins. Contemporary use of Astragalus membranaceus mainly focuses on its immunomodulating, anti-oxidant, and anti-inflammatory, as well as anticancer effects. In this paper, we summarize the properties of Astragalus membranaceus and its major constituents in the biological system based on experimental and clinical studies.

AIM: To explore probable mechanism underlying the therapeutic effect of Astragalus polysaccharide (APS) against experimental colitis.
