Ethanol Extract of Abnormal Savda Munziq, a Herbal Preparation of Traditional Uighur Medicine, Inhibits Caco-2 Cells Proliferation via Cell Cycle Arrest and Apoptosis

The In Vitro Protective Role of Bovine Lactoferrin on Intestinal Epithelial Barrier

The intestinal epithelial barrier plays a key protective role in the gut lumen. Bovine lactoferrin (bLF) has been reported to improve the intestinal epithelial barrier function, but its impact on tight junction (TJ) proteins has been rarely described. Human intestinal epithelial crypt cells (HIECs) were more similar to those in the human small intestine, compared with the well-established Caco-2 cells. Accordingly, both HIECs and Caco-2 cells were investigated in this study to determine the effects of bioactive protein bLF on their growth promotion and intestinal barrier function. The results showed that bLF promoted cell growth and arrested cell-cycle progression at the G2/M-phase. Moreover, bLF decreased paracellular permeability and increased alkaline phosphatase activity and transepithelial electrical resistance, strengthening barrier function. Immunofluorescence, western blot and quantitative real-time polymerase chain reaction revealed that bLF significantly increased the expression of three tight junction proteins-claudin-1, occludin, and ZO-1-at both the mRNA and protein levels, and consequently strengthened the barrier function of the two cell models. bLF in general showed higher activity in Caco-2 cells, however, HIECs also exhibited desired responses to barrier function. Therefore, bLF may be incorporated into functional foods for treatment of inflammatory bowel diseases which are caused by loss of barrier integrity.

Inhibition of nuclear factor kappa B pathway protects myocardial ischemia/reperfusion injury in rats under treatment with abnormal savda munziq

OBJECTIVE

Uighur medicine Fufang Munziq granule (Munziq) [corrected] shows cardioprotective effect in myocardial ischemia/reperfusion injury (IRI) in animal models, but the molecular mechanism of this effect is not clear. The present study investigates the regulation of nuclear factor kappa B (NF-kappa B) pathway by Fufang Munziq granule (Munziq) in IRI rat models.

METHODS

Male Sprague-Dawley rats were divided into three groups: the NF-κB gene knockout group (n = 5); the NF-κB transgenic group (n = 8); and the control group (n = 5). All rats were treated with Fufang Munziq granule (Munziq) [corrected] for 21 days before underwent IRI surgical procedure. Blood and tissue samples were collected for the RT-PCR, ELISA, western blot and other examination.

RESULTS

Expression of NF-κB p65mRNA and protein were down-regulated in the NF-κB knockout rats but up-regulated in the transgenic rats comparing with the controls (P<0.05). The upstream NF-κB kinase expressions, the downstream inflammatory cytokines, and the myocardial injury markers were all changed in accordance with the NF-κB gene modification (all P values <0.05). AMSq treatment relieved IRI in the NF-κB knockout rats.

CONCLUSION

Inhibition on NF-κB signaling pathway may alleviate IRI in rats under Fufang Munziq granule (Munziq) [corrected] treatment.

A New Strategy for Deleting Animal drugs from Traditional Chinese Medicines based on Modified Yimusake Formula

Traditional Chinese medicine (TCM), such as Uyghur Medicine (UM) has been used in clinical treatment for many years. TCM is featured as multiple targets and complex mechanisms of action, which is normally a combination of medicinal herbs and sometimes even contains certain rare animal medicinal ingredients. A question arises as to whether these animal materials can be removed replaced from TCM applications due to their valuable rare resources or animal ethics. Here, we select a classical UM Yimusake formula, which contains 3 animal drugs and other 8 herbs, and has got wealthy experience and remarkable achievements in treating erectile dysfunction (ED) in China. The active components, drug targets and therapeutic mechanisms have been comprehensively analyzed by systems-pharmacology methods. Additionally, to validate the inhibitory effects of all candidate compounds on their related targets, in vitro experiments, computational analysis and molecular dynamics simulations were performed. The results show that the modified, original and three animal materials display very similar mechanisms for an effective treatment of ED, indicating that it is quite possible to remove these three animal drugs from the original formula while still keep its efficiency. This work provides a new attempt for deleting animal materials from TCM, which should be important for optimization of traditional medicines.

Anti-tumor effects of Abnormal Savda Munziq on the transplanted cervical cancer (U27) mouse model

BACKGROUND

Abnormal Savda Munziq (ASMq), a traditional uyghur medicine, has shown anti-tumour properties in vitro. it was showed that total flavonoids of ASMq could inhibit the proliferation and enhance the antioxidant ability of human cervix cancer HeLa cell. This study attempts to confirm these effects on the transplanted cervical cancer (U27) mouse model in vivo.

METHODS

Forty eight Kunming mice were randomly divided in to six groups: normal control group (Control group), U27 tumor model group (Model group), cyclophosphamide administration group (CTX group),low-dose ASMq group (ASMq.L group), medium-dose ASMq group (ASMq.M group), and high-dose ASMq group (ASMq.H group). The five groups except normal control group transplanted with cervical cancer (U27) cells. We observed mice tumor inhibition rate and conducted the histopathological analysisUsing the western blot assay, the expression of TGF-β1 and TNF-α protein in transplanted cervical cancer U27 tumor tissue were detected.

RESULTS

The tumor inhibition rates of CTX group, ASMq.L group, ASMq.M group, and ASMq.H group were 72.21, 31.27, 60.53 and 51.94% respectively, has obvious antitumor effect. ASMq significantly promote the spleen tlymphocyte proliferation of transplanted cervical cancer U27 mice. Invasive growth and diffusion rate in tumor tissue were accelerate in the transplanted cervical cancer U27 model group. Tumor tissue necrosis of tumor cells are smaller in the medium, high dosage group. Compared with the U27 model group, the expression levels of TGF-β1 protein and TNF-α protein expression exhibited statistically significant decreased in the mice tumor tissues in the CTX administration group and the ASMq administration group.

CONCLUSIONS

ASMq has some antitumor effects on U27 model mice in vivo, The effects are achieved not only by improving the immune function of U27 model mice, but also by inhibiting the expression levels of TGF-β1 protein while promoting the expression levels of TNF-α protein.

News from Tartary: an ethnopharmacological approach to drug and therapeutic discovery

Ethnopharmacology aims to identify new therapeutic agents based on their traditional use. It begins by the identification of disease states, and of the traditional therapies for these, most commonly herbals. Herbals of interest are selected from ethnopharmacological surveys, and tested on experimental models of the diseases of interest. Once the activity of the traditional remedy is demonstrated, including dose-dependence, if possible comparatively to reference medications, the active ingredients can be explored, if possible using bioguided extraction. Identified molecules can then be further developed as medicinal products or pharmaceutical medicines (e.g., artemisine), or the herbal product can be developed as such (e.g. St John's wort). We provide examples of various study programmes, concerning the antiplatelet and antithrombotic effects of Armagnac extracts from Southwest France; antithrombotic and antihypertensive effects of extracts of Ocimum basilicum L; antithrombotic, antihypertensive and antihyperlipidemic effects of Cydonia oblonga; Antiproliferative and antithrombotic effects of Abnorma Savda Munziq of traditional Uyghur medicine; and the antidiabetic and hepatoprotective effects of Centaurium erythraea Rafn, Artemisia herba-alba Asso and Trigonella foenum-graecum L., all in collaboration between University of Bordeaux, France, Xinjiang Medical University in Urumqi, China and University Mentouri in Constantine, Algeria.

Transcriptome Profiling Reveals the Antitumor Mechanism of Polysaccharide from Marine Algae Gracilariopsis lemaneiformis

Seaweed is one of the important biomass producers and possesses active metabolites with potential therapeutic effects against tumors. The red alga Gracilariopsis lemaneiformis (Gp. lemaneiformis) possesses antitumor activity, and the polysaccharide of Gp. lemaneiformis (PGL) has been demonstrated to be an ingredient with marked anticancer activity. However, the anticancer mechanism of PGL remains to be elucidated. In this study, we analyzed the inhibitory effect of PGL on the cell growth of 3 human cancer cell lines and found that PGL inhibited cell proliferation, reduced cell viability, and altered cell morphology in a time- and concentration-dependent manner. Our transcriptome analysis indicates that PGL can regulate the expression of 758 genes, which are involved in apoptosis, the cell cycle, nuclear division, and cell death. Furthermore, we demonstrated that PGL induced apoptosis and cell cycle arrest and modulated the expression of related genes in the A549 cell line. Our work provides a framework to understand the effects of PGL on cancer cells, and can serve as a resource for delineating the antitumor mechanisms of Gp. lemaneiformis.

Differential integrative omic analysis for mechanism insights and biomarker discovery of abnormal Savda syndrome and its unique Munziq prescription

Research has shown that many cancers have acommon pathophysiological origin and often present with similar symptoms. In terms of Traditional Uighur Medicine (TUM) Hilit (body fluid) theory, abnormal Savda syndrome (ASS) formed by abnormal Hilit is the common phenotype of complex diseases and in particular tumours. Abnormal Savda Munziq (ASMq), one representative of TUM, has been effective in the treatment of cancer since ancient times. Despite the physiopathology of ASS, the relationship between causative factors and the molecular mechanism of ASMq are not fully understood. The current study expanded upon earlier work by integrating traditional diagnostic approaches with others utilizing systems biology technology for the analysis of proteomic (iTRAQ) and metabolomic (¹H-NMR) profiles of Uighur Medicine target organ lesion (liver) tumours. The candidate proteins were analyzed by enrichment analysis of the biological process and biomarker filters. Subsequently, 3Omics web-based tools were used to determine the relationships between proteins and appropriate metabolites. ELISA assay and IHC methods were used to verify the proteomic result; the protein von Willebrand factor (vWF) may be the “therapeutic window” of ASMq and biomarkers of ASS. This study is likely to be of great significance for the standardization and modernization of TUM.

Attenuation effect of Abnormal Savda Munziq on liver and heart toxicity caused by chemotherapy in mice

Abnormal Savda Munziq (ASMq), an Uighur medicine formula commonly used in the treatment of cancer, has been speculated to possess antioxidative and antiproliferative effects, and to regulate immune activity. The present study was designed to systematically elucidate the toxicity-reducing activity of ASMq in mice undergoing combination chemotherapy with doxorubicin and 5-fluorouracil (5-FU). The mice were divided into normal (saline, 10 ml/kg) and doxorubicin + 5-FU groups (doxorubicin, 2.5 mg/kg; 5-FU, 10 mg/kg on alternate days). In addition, three groups received different doses of ASMq (2, 4 and 8 g/kg), in addition to doxorubicin (2.5 mg/kg) and 5-FU (10 mg/kg) treatment on alternate days. The histology of the heart and liver, superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activity, malondialdehyde (MDA) concentrations in heart homogenate, and various biochemical parameters of the liver were evaluated. Compared with the normal control group, ASMq dose-dependently improved a number of variables, including body weight, liver index, transaminase and total protein, and partially normalized liver and cardiac pathology. ASMq restored activities of defense antioxidant enzymes SOD and GSH-Px towards normal levels, and decreased MDA concentration in dose-dependent manner. These results demonstrated that ASMq provides significant protection against doxorubicin + 5-FU combination induced hepatotoxicity and cardiotoxicity. Further studies are required to determine the effects of ASMq against doxorubicin + 5-FU-induced toxicity during chemotherapy in vivo.

Metabolic differentiation and classification of abnormal Savda Munziq's pharmacodynamic role on rat models with different diseases by nuclear magnetic resonance-based metabonomics

Background:

Abnormal Savda Munziq (ASMq) is a traditional Uyghur herbal preparation used as a therapy for abnormal Savda-related diseases. In this study, we investigate ASMq's dynamic effects on abnormal Savda rat models under different disease conditions.

Materials and Methods:

Abnormal Savda rat models with hepatocellular carcinoma (HCC), type 2 diabetes mellitus (T2DM), and asthma dosed of ASMq. Serum samples of each animal tested by nuclear magnetic resonance spectroscopy and analyzed by orthogonal projection to latent structure with discriminant analysis.

Results:

Compared with healthy controls, HCC rats had higher concentrations of amino acids, fat-related metabolites, lactate, myoinositol, and citrate, but lower concentrations of α-glucose, β-glucose, and glutamine. Following ASMq treatment, the serum acetone very low-density lipoprotein (VLDL), LDL, unsaturated lipids, acetylcysteine, and pyruvate concentration decreased, but α-glucose, β-glucose, and glutamine concentration increased (P < 0.05). T2DM rats had higher concentrations of α- and β-glucose, but lower concentrations of isoleucine, leucine, valine, glutamine, glycoprotein, lactate, tyrosine, creatine, alanine, carnitine, and phenylalanine. After ASMq treated T2DM groups showed reduced α- and β-glucose and increased creatine levels (P < 0.05). Asthma rats had higher acetate, carnitine, formate, and phenylalanine levels, but lower concentrations of glutamine, glycoprotein, lactate, VLDL, LDL, and unsaturated lipids. ASMq treatment showed increased glutamine and reduced carnitine, glycoprotein, formate, and phenylalanine levels (P < 0.05).

Conclusion:

Low immune function, decreased oxidative defense, liver function abnormalities, amino acid deficiencies, and energy metabolism disorders are common characteristics of abnormal Savda-related diseases. ASMq may improve the abnormal metabolism and immune function of rat models with different diseases combined abnormal Savda.

Investigations into cytotoxic effects of the herbal preparation Abnormal Savda Munziq

OBJECTIVE

To evaluate the effects of Abnormal Savda Munziq (ASMq), a traditional herbal medicine, for the prevention and treatment of human diseases, e.g. bowel cancer.

METHODS

The parameters total polyphenol content, cell proliferation and DNA-damage as well as RNA and protein-oxidation were analysed in vitro. Besides, the expressions of miRNA and tumor suppressor genes as well as cellular senescence were evaluated.

RESULTS

ASMq had a high polyphenol content and induced damage to proteins, RNA as well as to DNA, which is correlated with its cytotoxicity. Furthermore ASMq up-regulated the tumor suppressor genes p21, p53 and p16 and down-regulated the micro-RNAs hsa-mir-17 and hsa-mir-106b. In addition cellular growth arrest and SA-β-gal-staining were induced.

CONCLUSION

Identification of plasma protein markers common to patients with malignant tumour and Abnormal Savda in Uighur medicine: a prospective clinical study

Background

Traditional Uighur medicine shares an origin with Greco-Arab medicine. It describes the health of a human body as the dynamic homeostasis of four normal Hilits (humours), known as Kan, Phlegm, Safra, and Savda. An abnormal change in one Hilit may cause imbalance among the Hilits, leading to the development of a syndrome. Abnormal Savda is a major syndrome of complex diseases that are associated with common biological changes during disease development. Here, we studied the protein expression profile common to tumour patients with Abnormal Savda to elucidate the biological basis of this syndrome and identify potential biomarkers associated with Abnormal Savda.

Methods

Patients with malignant tumours were classified by the diagnosis of Uighur medicine into two groups: Abnormal Savda type tumour (ASt) and non-Abnormal Savda type tumour (nASt), which includes other syndromes. The profile of proteins that were differentially expressed in ASt compared with nASt and normal controls (NC) was analysed by iTRAQ proteomics and evaluated by bioinformatics using MetaCore™ software and an online database. The expression of candidate proteins was verified in all plasma samples by enzyme-linked immunosorbent assay (ELISA).

Results

We identified 31 plasma proteins that were differentially expressed in ASt compared with nASt, of which only 10 showed quantitatively different expression between ASt and NC. Bioinformatics analysis indicated that most of these proteins are known biomarkers for neoplasms of the stomach, breast, and lung. ELISA detection showed significant upregulation of plasma SAA1 and SPP24 and downregulation of PIGR and FASN in ASt compared with nASt and NC (p < 0.05).

Conclusions

Abnormal Savda may be causally associated with changes in the whole regulation network of protein expression during carcinogenesis. The expression of potential biomarkers might be used to distinguish Abnormal Savda from other syndromes.

Effect of traditional Uyghur medicine abnormal Savda Munziq extract on rabbit platelet aggregation in vitro and rat arteriovenous shunt thrombosis in vivo

OBJECTIVE

Abnormal Savda Munziq (ASMq) is a standard herbal preparation used in Uyghur traditional medicine to fight chronic diseases including cardiovascular, but its specific effects on thrombosis and platelet aggregation are unknown.

METHODS

Rabbit platelets were incubated with ASMq extract (10, 20, 40 µg/ml) for 15, 30, or 60 min, and aggregation was induced with ADP and collagen. In vivo, ASMq extract 2.97 g/kg, 5.94g/kg, 11.88 g/kg per os daily for 15 days were tested on thrombus wet weight in a rat model of arterio-venous bypass thrombosis. Plasma thromboxane B2 (TXB2) and 6-keto-PGF1a (6PG) were measured by radioimmunoassay. Aspirin (12 µg/ml and 5mg/kg) and saline were used as control in both experiments.

RESULTS

ASMq inhibited ADP and collagen-induced aggregation in vitro in a dose-dependent manner that increased over time, to a maximum of 6.4 ± 1.3% and 21.6 ± 4.0% for ADP and collagen, respectively, at one hour׳s incubation with the highest concentration, whereas the effects of aspirin (34.5 ± 2.2% and 41.9 ± 2.5%, respectively) were stable over time. In vivo, ASMq inhibited thrombus formation dose-dependently, by 70% at the highest dose, compared to 67% with aspirin. ASMq essentially did not change prostaglandin production, compared to the clear inhibition by aspirin.

CONCLUSION

Abnormal Savda Munziq extract inhibits dose-dependent platelet aggregation with ADP or collagen in vitro and thrombosis in vivo to values similar to those of aspirin, though unlike aspirin this effect does not seem mediated by an inhibition of cyclo-oxygenase.

Immunomodulatory and antitumour effects of abnormal Savda Munziq on S180 tumour-bearing mice

Background

Abnormal Savda Munziq (ASMq), a traditional uyghur medicine, has shown anti-tumour properties in vitro. This study attempts to confirm these effects in vivo and measure effects on the immune system.

Methods

Kunming mice transplanted with Sarcoma 180 cells were treated with ASMq (2–8 g/kg/day) by intra-gastric administration compared to model and cyclophosphamide (20 mg/kg/day). After the 14th day post tumour implant, thymus, liver, spleen and tumours were removed, weighed, and processed for histopathological analysis. Blood samples were also taken for haematological and biochemical analyses including TNF-α , IL-1 β and IL-2. Splenic lymphocyte function was measured with MTT; lymphocyte subpopulations were measured by flow cytometry.

Results

ASMq treated animals had reduced tumour volume compared to model and increased concentrations of TNF-α, IL-1β and IL-2 compared to untreated and to cyclophosphamide-treated animals. No histopathological alterations were observed. The absence of viable S180 cells and the presence of necrotic cells and granulation tissue were observed in tumour tissue of treated animals. The effect on T lymphocytes was unclear.

Conclusions

ASMq confirmed in vivo anti-tumour effects observed in vitro, which may be at least in part mediated by increased immune activity.
