Danggui Shaoyao powder improves hepatic lipid metabolism in atherosclerosis mice via PPARγ-LXRα-ABCA1 pathway regulation

Objective:To observe the effects of Danggui Shaoyao powder(DSP)on hepatic lipid metabolism and further explore its mechanism of action by peroxisome proliferator-activated receptor(PPARγ)-liver X receptor(LXRα)-adenosine triphosphate(ATP)-binding cassette transporter A1(ABCA1)pathway regulation.Methods: Eight C57BL/6J male mice were selected as the control group,and 24 ApoE^(−/−)male mice were randomly divided into the atherosclerosis model(AS)group,atorvastatin calcium(AC)group,and DSP group(n=8 each group).To establish an AS model,ApoE^(−/−)mice were fed a high-fat diet for 16 weeks.Pathologic changes in the aortic vasculature and liver were identified using Oil Red O staining.Triglyceride(TG),cholesterol(TC),and low-density lipoprotein cholesterol(LDL-C)levels were determined in the livers using a single-reagent GPO-PAP method.Fluorescence quantitative polymerase chain reaction and western blot were used to observe and evaluate the mRNA and protein expression of the PPARγ-LXRα-ABCA1 intermediates in the liver.Results: After 16 weeks of a high-fat diet,ApoE^(−/−)mice showed more Oil Red O staining in the aorta and liver compared to the CONT group.Compared to the AS group,the DSP and AC treatment reduced aortic plaque and hepatic lipid deposition to varying degrees.Furthermore,DSP significantly reduced the hepatic lipid area in ApoE^(−/−)mice(P<.001)and decreased the levels of TG,TC,and LDL-C in liver(P<.001,P=.027,P<.001,respectively).DSP also significantly increased the levels of PPARγ,LXRα,ABCA1,and ABCG1 mRNA expression,as well as the PPARγ,LXRα,ABCA1,and ABCG1 protein expression in liver.Conclusion: DSP improved hepatic lipid metabolism via PPARγ-LXRα-ABCA1 pathway modulation for AS treatment.

Herb pair of Huangqi-Danggui exerts anti-tumor immunity to breast cancer by upregulating PIK3R1

Background:According to traditional Chinese medicine(TCM),drugs supplementing the vital energy,Qi,can eliminate tumors by restoring host immunity.The objective of this study is to investigate the underlying immune mechanisms of anti-tumor activity associated with Qi-supplementing herbs,specifically the paired use of Huangqi and Danggui.Methods:Analysis of compatibility regularity was conducted to screen the combination of Qi-supplementing TCMs.Using the MTT assay and a transplanted tumor mice model,the anti-tumor effects of combination TCMs were investigated in vitro and in vivo.High content analysis and flow cytometry were then used to evaluate cellular immunity,followed by network pharmacology and molecular docking to dissect the significant active compounds and potential mechanisms.Finally,the anti-tumor activity and the mechanism of the active ingredients were verified by molecular experiments.Results:There is an optimal combination of Huangqi and Danggui that,administered as an aqueous extract,can activate immunity to suppress tumor and is more effective than each drug on its own in vitro and in vivo.Based on network pharmacology analysis,PIK3R1 is the core target for the anti-tumor immunity activity of combined Huangqi and Danggui.Molecular docking analysis shows 6 components of the combined Danggui and Huangqi extract(quercetin,jaranol,isorhamnetin,kaempferol,calycosin,and suchilactone)that bind to PIK3R1.Jaranol is the most important component against breast cancer.The suchilactone/jaranol combination and,especially,the suchilactone/kaempferol combination are key for immunity enhancement and the anti-tumor effects of the extract.Conclusions:The combination of Huangqi and Danggui can activate immunity to suppress breast cancer and is more effective than the individual drugs alone.

Therefore, all results showed DBT had prevention effects against the progression of AGEs-induced damage, and this decoction might be promising agent against proteinuria in diabetic nephropathy.

Traditional herbal medicines,Fuling,Baizhu,and Danggui,promote the proliferation of human Schwann cells

Enhancing Schwann cell proliferation may be beneficial for peripheral nerve repair and nerve regeneration. A traditional herbal formula composed of Fuling （poria cocos）, Baizhu （Atractylodes macrocephala）, and Danggui （Angelica sinensis） （FBD） improves neuronal survival and growth, and FBD may promote the secretion of brain-derived neurotrophic factor. However, the mechanism underlying Schwann cell proliferation remains unclear. We tested whether FBD enhanced the proliferation of human Schwann cells. FBD （20 ug/mL） increased Schwann cell viability and survival and increased the number of cells at G2/M and S phases. FBD also increased nerve growth factor and brain-derived neurotrophic factor expression in Schwann cells, with maximum efficacy at 20 ug/mL.
