The impact of the Uighur medicine abnormal savda munziq on antitumor and antioxidant activity in a S180 and Ehrlich ascites carcinoma mouse tumor model

Enhanced efficacy with reduced toxicity of chemotherapy drug 5-fluorouracil by synergistic treatment with Abnormal Savda Munziq from Uyghur medicine

Background

Abnormal Savda Munziq (ASMq) is a traditional prescription in Uyghur Medicine, and its treatment of complex diseases such as tumors and asthma has been proven to be effective in Uyghur medical clinical practice. The efficacy-enhancing and toxicity-reducing properties of ASMq were studied on mice with transplanted cervical cancer (U27) tumors, which were treated with 5-fluorouracil (5-FU) in this work.

Methods

To investigate the synergistic effect of ASMq and 5-FU on U27 cells, inhibitory effects on cell proliferation were determined through a MTT assay. 48 Kunming mice which were randomly divided in to 6 groups: control group, model group, 5-FU group, 5-FU combine with ASMq low-dose group, 5-FU combine with ASMq medium-dose group, and 5-FU combine with ASMq high- dose group, the inhibition rate of the tumor, the viscera indexes, and the content of serum tumor necrosis factor-α (TNF-α), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were determined. The expression levels of transforming growth factor-β1 (TGF-β1) and human papillomavirus type 16 E2 (HPV16 E2) protein were assessed by Western blot. Pathological changes in the liver were observed.

Result

The inhibition rates of tumors, the 5-FU + ASMq.H group(80.64%), 5-FU + ASMq.M group (90.67%), 5-FU + ASMq.L group (72.03%) and 5-FU group (66.89%), clearly indicated that the effects of tumor inhibition. The thymus index and spleen index were increased, and the serum concentration of TNF-α increased while ALT and AST concentrations were decreased, and TNF-α protein expression were increased while TGF-β1 and HPV16 E2 were decreased. ASMq might can improve livers central vein hyperemia and interstitial edema, and preserve the radial structure of the hepatic cords.

Conclusions

The results suggested that ASMq might reduce toxicity and enhance the efficacy of the chemotherapeutic drug 5-fluorouracil in the treatment of cervical carcinoma.

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.

Long-Term Sodium Ferulate Supplementation Scavenges Oxygen Radicals and Reverses Liver Damage Induced by Iron Overloading

Ferulic acid is a polyphenolic compound contained in various types of fruits and wheat bran. As a salt of the active ingredient, sodium ferulate (SF) has potent free radical scavenging activity and can effectively scavenge ROS. In this study, we examined the effect of SF on iron-overloaded mice in comparison to a standard antioxidant, taurine (TAU). We determined the protective role of SF against liver injury by examining liver-to-body ratio (%), transaminase and hepatocyte apoptosis in rats supplied with 10% dextrose intraperitoneal injection. In addition, antioxidative enzymes activities, ROS formation, mitochondrial swelling, and mitochondrial membrane potential (MMP) were all evaluated to clarify the mechanism of protective effect of SF associated with oxidative stress. After 15 weeks of SF treatment, we found a significant reduction in liver-to-body weight radio and elevation in both transaminase and hepatocyte apoptosis associated with iron-injected to levels comparable to those achieved with TAU. Both SF and TAU significantly attenuated the impaired liver function associated with iron-overloaded in mice, whereas neither showed any significant effect on the iron uptake. Furthermore, treatment with either SF or TAU in iron-overloaded mice attenuated oxidative stress, associated with elevated oxidant enzymes activities, decreased ROS production, prevented mitochondrial swelling and dissipation of MMP and then inhibited hepatic apoptosis. Taken together, the current study shows that, SF alleviated oxidative stress and liver damage associated with iron-overload conditions compared to the standard ROS scavenger (TAU), and potentially could encourage higher consumption and utilization as healthy and sustainable ingredients by the food and drink.

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.

Antioxidant properties of repaglinide and its protections against cyclosporine A-induced renal tubular injury

OBJECTIVES

Repaglinide (RG) is an antihyperglycemic agent used for the treatment of non-insulin-dependent diabetes mellitus. It has a good safety and efficacy profile in diabetic patients with complications in renal impairment and is an appropriate treatment choice, even for individuals with more severe degrees of renal malfunctions. The aim of the present study was to examine the protective effect of RG on cyclosporine A (CsA)-induced rat renal impairment and to evaluate the antioxidant mechanisms by which RG exerts its protective actions.

MATERIALS AND METHODS

Fifty male Sprague-Dawley rats weighing 250-300 g were randomly divided into five groups: administrations of olive oil (control, PO), RG (0.4 mg/kg, PO), CsA (30 mg/kg in olive oil, SC), RG (0.2 or 0.4 mg/kg, PO) plus CsA (30 mg/kg in olive oil SC) every day for 15 days.

RESULTS

SC administration of CsA (30 mg/kg) to rats produced marked elevations in the levels of renal impairment parameters such as urinary protein, N-acetyl-beta-D-glucosaminidase (NAG), serum creatinine (SCr), and blood urea nitrogen (BUN). It also caused histologic injury to the kidneys. Oral administration of RG (0.2 and 0.4 mg/kg) markedly decreased all the aforementioned changes. In addition, CsA caused increases in the levels of malondialdehyde (MDA) and decreases in superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), glutathione reductase (GSR), glutathione-S-transferase (GST), and glutathione in kidney homogenate, which were reversed significantly by both doses of RG.

CONCLUSION

The findings of our study indicate that RG may play an important role in protecting the kidney from oxidative insult.

The Attenuation of Scutellariae radix Extract on Oxidative Stress for Colon Injury in Lipopolysaccharide-induced RAW264.7 Cell and 2,4,6-trinitrobenzene Sulfonic Acid-induced Ulcerative Colitis Rats

Background:

Oxidative stress (OS) has been regarded as one of the major pathogeneses of ulcerative colitis (UC) through damaging colon. It has been shown that Scutellariae radix (SR) extract has a beneficial effect for the prevention and treatment of UC.

Objective:

The aim of this study was to investigate whether SR had a potential capacity on oxidant damage for colon injury both in vivo and in vitro.

Materials and Methods:

The 2,4,6-trinitrobenzene sulfonic acid (TNBS) was used to induce UC rats model while 1 μg/ml lipopolysaccharide (LPS) was for RAW264.7 cell damage. Disease activity index (DAI) was determined to response the severity of colitis. The myeloperoxidase (MPO) activity in rat colon was also estimated. The 2,2’-azino-bis-3-ethylbenzthiazoline-6-sulfonic acid assay was performed to evaluate the total antioxidant capacity of SR. Furthermore, the activity of glutathione peroxidase (GSH-PX), catalase (CAT), superoxide dismutase (SOD), and lipid peroxidation malondialdehyde (MDA) in cell supernatant and rat serum were detected by appropriate kits. In addition, an immunohistochemical assay was applied to examine transforming growth factor beta 1 (TGF-β1) protein expression in colon tissue.

Results:

The treatment with SR could significantly increase the activity of GSH-PX, CAT, and SOD associated with OS in LPS-induced RAW264.7 cell damage and TNBS-induced UC rats. However, the level of MDA was markedly reduced both in vitro and in vivo. Furthermore, SR significantly decreased DAI and reversed the increased MPO activity. Thus, SR could decrease the severity of acute TNBS-induced colitis in rats. Immunohistochemical assay showed that SR significantly downregulated TGF-β1 protein expression in colon tissue.

Conclusion:

Our data provided evidence to support this fact that SR attenuated OS in LPS-induced RAW264.7 cell and also in TNBS-induced UC rats. Thus, SR may be an interesting candidate drug for the management of UC.

SUMMARY

Scutellariae radix (SR) could significantly increase the activity of glutathione peroxidase, catalase, and superoxide dismutase associated with OS in lipopolysaccharide-induced RAW264.7 cell damage and 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced ulcerative colitis rats

The level of malondialdehyde was markedly reduced by SR both in vitro and in vivo

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

ASMq has the ability to induce DNA damage and cellular senescence, which are double-edged mechanisms in fighting cancer, as they might also have harmful side effects.

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.

The treatment of Uygur medicine Dracocephalum moldavica L on chronic mountain sickness rat model

Aim:

Dracocephalum moldavica L, a traditional Uygur medicine, possesses some key cardiac activities. However, till date, no reports are available on the use of D. moldavica against chronic mountain sickness (CMS), which is a medical condition that affects the residents of high altitude. The present study was designed to explore the treatment efficacy of D. moldavica on CMS.

Materials and Methods:

80 of the 100 Sprague Dawley rats enrolled were bred in simulated high altitude environment and the remaining 20 rats were kept in the plains. Water and alcohol extracts of D. moldavica were prepared. CMS rat model was prepared, and the rat hearts were removed for histopathological analysis. Blood samples were taken for hematological and biochemical analyses. Rat pulmonary artery pressure was determined to study the treatment efficacy.

Results:

In the CMS model group, the levels of interleukin-6 (IL-6), C-reactive protein (CRP), and malondialdehyde (MDA) were found to be significantly higher than the control group; while the concentrations of SOD and GSH-Px decreased. D. moldavica could improve these levels, decrease pulmonary artery pressure, and improve the cardiac pathological state.

Conclusions:

The study results show that IL-6, CRP, MDA, SOD and GSH-Px participate and mediate the formation of CMS and D. moldavica is found to possess noticeable effects on CMS. The present study explored the basics of high altitude sickness and laid the foundation for further progress of Uygur medicines on the treatment of altitude sickness. Further preclinical and clinical studies with more sample size are recommended.

Mechanisms of hela cell apoptosis induced by abnormal Savda Munziq total phenolics combined with chemotherapeutic agents

OBJECTIVE

To investigate the effects of abnormal Savda Munziq (ASMq) total phenolics combined with cisplatin and docetaxel on the Hela cell growth.

METHODS

In vivo cultured Hela cells were treated with cisplatin, docetaxel, total phenolics, cisplatin+total phenolics or docetaxel+total phenolics. MTT was performed to assess inhibition of cell proliferation, flow cytometry to detect apoptosis, and semi-quantitative RT-PCR to test for survivin and Bcl-2 expression.

RESULTS

The total phenolics, cisplatin and docetaxel had significant inhibitory and apoptosis-promoting effects on Hela cells (P<0.05), with the early apoptotic rates of 12.8±0.70%, 18.9±3.79% and 15.8±3.8)%; the total phenolics, cisplatin and docetaxel significantly decreased the expression of Bcl-2 and survivin (all P<0.01), especially when used in combination.

CONCLUSION

ASMq total phenolics, combined with cisplatin and docetaxel, could promote the apoptosis of Hela cells possibly through reducing the expression of Bcl-2 and survivin.

The attenuation of Moutan Cortex on oxidative stress for renal injury in AGEs-induced mesangial cell dysfunction and streptozotocin-induced diabetic nephropathy rats

Oxidative stress (OS) has been regarded as one of the major pathogeneses of diabetic nephropathy (DN) through damaging kidney which is associated with renal cells dysfunction. The aim of this study was to investigate whether Moutan Cortex (MC) could protect kidney function against oxidative stress in vitro or in vivo. The compounds in MC extract were analyzed by HPLC-ESI-MS. High-glucose-fat diet and STZ (30 mg kg⁻¹) were used to induce DN rats model, while 200 μg mL⁻¹ AGEs were for HBZY-1 mesangial cell damage. The treatment with MC could significantly increase the activity of SOD, glutathione peroxidase (GSH-PX), and catalase (CAT). However, lipid peroxidation malondialdehyde (MDA) was reduced markedly in vitro or in vivo. Furthermore, MC decreased markedly the levels of blood glucose, serum creatinine, and urine protein in DN rats. Immunohistochemical assay showed that MC downregulated significantly transforming growth factor beta 2 (TGF-β2) protein expression in renal tissue. Our data provided evidence to support this fact that MC attenuated OS in AGEs-induced mesangial cell dysfunction and also in high-glucose-fat diet and STZ-induced DN rats.
