ABSTRACT

Introduction@#Air pollution has become one of the major problems in socio-economic and health issues in Mongolia. Among the various hazards of particulate matter (PM) pollutants, microorganisms in PM2.5 and PM10 are thought to be responsible for various allergies and for the spread of respiratory diseases. Recent studies have shown that PM2.5 particles can cause chronic heart failure, heart arrhythmias, and strokes, as well as lung damage, cirrhosis, inflammation, cancer, cardiovascular disease, and metabolic disorders. Furthermore, some studies have concluded that PM2.5 particles in the environment are a risk factor for gastrointestinal, liver, colon, and lung cancer as well as it affects the growth and metastasis of various cancer cells caused by other factors. In our country, the health effects of air pollution and the relationship between the pathogenesis of cancer research are scarce. Therefore, the study of the effects of PM2.5 particles on cancer cell proliferation, migration (metastasis) can provide a significant role for cancer treatment, diagnosis, and prevention.@*Purpose@#Determining the effects of PM2.5 particles on cancer cell proliferation, migration (metastasis) in in-vitro@*Material and Methods@#A human liver cancer cell line (HepG2), human gastric cancer cell line (AGS) were obtained from the central scientific research laboratory in the Institute of medical sciences. HepG2, AGS cells were seeded at a concentration of 1*105 cells/mL in a culture flask and cultured in RPMI-1640 medium supplemented with 10% FBS, 1% antibiotic mix (penicillin, streptomycin) in a humidified atmosphere of 5% CO2 at 37 °C. The cytotoxic effect of PM 2.5 in AGS, HepG2 cells were evaluated by MTT, CCK8 assays. AGS, HepG2 cells were incubated in 96 well plates for 24h then treated with different concentrations (0, 5, 10, 25, 50 and 100 μg ) of Bayankhoshuu, Buhiin urguu, and Zaisan samples for 24h, respectively.@*Results@#Concentrations of 10, 25, and 50 μg/ml of samples collected from the Bukhiin urguu and Zaisan in March increased HepG2 cell growth, while doses of 25, 50 μg/ml of samples collected from Bayankhoshuu in March and December increased HepG2 cell growth. Therefore, concentrations of 25 and 50 μg/ml of samples collected from Bayankhoshuu in March increased AGS cell growth, while concentrations of 25, 100 and μg/ml of samples collected in December increased AGS cell growth. However, no cytotoxic effect was observed in the sample collected from Zaisan in March, whereas the PM2.5 sample enhanced AGS cell growth in dose dependent manner in December.(p <0.05) @*Conclusion@#High levels of heavy metals were detected in samples collected in December from Bayankhoshuu, Bukhiin urguu and Zaisan of Ulaanbaatar. Concentration of 25 μg/ml of samples collected from the Bukhiin urguu and Zaisan in March increased HepG2 cell growth. Concentrations of 25 μg/ml of PM2.5 collected from three regions around Ulaanbaatar increased HepG2 and AGS cell migration.

ABSTRACT

Background and Aims@#Hepatocellular carcinoma (HCC) is a common cause of cancer related death in Mongolia. Early diagnosis is the very important management to increase successful treatment and survival rate. Glypican-3 (GPC3) protein is highly expressed in hepatocellular carcinoma (HCC) tissue and in serum of HCC patients. Recent studies have been conducted and suggested as a diagnostic biomarker for detecting HCC in the early stage. Therefore, we investigated the diagnostic value of the serum GPC3 level and compared it to the alpha-fetoprotein (AFP) level as a diagnostic biomarker of HCC.@*Methods@#We enrolled a total of 90 participants and divided into 3 groups with HCC (30), with liver cirrhosis (LC/30) and healthy (30) as the control group (30). GPC3 and AFP serum (sGPC-3, sAFP) levels were measured using commercially available enzyme-linked immunosorbent assay kits. The diagnostic accuracy was analyzed using the receiver operating characteristics (ROC) curve and estimated sensitivity and specificity of each biomarker. @*Results@#sGPC3 was significantly elevated in the HCC group as compared to liver cirrhosis and healthy subjects (658±138.2 pg/ml, 378±25.5 pg/ml, 356.3±29 pg/ml) respectively. sGPC-3 sensitivity was 96.6% and specificity was 100%. The area under the ROC curve (AUC) for GPC3 was 0.999 (0.996- 1.0).</br> In comparison, the mean of AFP was significantly higher in HCC (16.9±11.7 ng/ml) than in LC (6.7±7.6 ng/ml) and in healthy subject (3.3±2.1 ng/ml) and AFP sensitivity was 43,3 %, specificity was 95 % with an AUC of 0.808 (0.696- 0.921). </br> The combination of GPC-3 with AFP achieved the highest sensitivity (97.1%) and specificity (97%).@*Conclusion@#Serum GPC3 has a higher sensitivity than AFP for the early diagnosis of HCC. Combination of two markers showed greatest diagnostic accuracy.

ABSTRACT

@#Research of function of vitamin D on immune system has been studying since the study revealed that vitamin D receptor is expressed on the surface of the immune cells. 1,2-dihydroxyvitamin D3 [1,25(OH)2D], physiologically active form, can be generated through hydroxylation of 25-hydroxyvitamin D3 [25(OH)D], inactive form of vitamin D, in a liver, connecting with specific VDR make biological action. Vitamin D make different biological actions depends on connecting with different immunological cells. Some studies indicated that Vitamin D plays pivotal role in antibacterial innate immune responses through regulating reaction of the main cells as macrophages and dendritic cells. Moreover, calcitriol, the active form of vitamin D, is connected with VDRE, modulates the innate immune response through directly inducing expression of catelicithin and β-defensin as antimicrobial peptides, reducing secretion of IL-1b, IL-6, TNF-a, RANKL, COX-2 as proinflammatory cytokines and increasing production of IL-10, an anti-inflammatory cytokine. Vitamin D plays in proliferation and differentiation of T and B cells and regulates the activities of over 500 genes. Vitamin D differently impacts on per se stages of T cells’ proliferation. Vitamin D indirectly mitigates the differentiation from immature B cells to plasma B cells while it directly impacts on regulation of overloaded production of antibodies in plasma B cells. In conclusion, vitamin D modulates the innate- and adaptive immune response through regulation on activation of APCells, proliferation and differentiation of immune cells, secretion of some antibacterial peptides.

ABSTRACT

Background@#The incidence of acute SAH has been estimated at 2–22 cases per 100 000 persons per year. The most common cause of basal acute SAH is a ruptured cerebral aneurysm. Cerebral vasospasm in the first 2 weeks after aneurysmal subarachnoid hemorrhage is recognized as a major predictor of delayed cerebral ischemia. From 2014 through 2018, 5272 patients with a stroke (amongst them 20.4% were patients with aSAH) were hospitalized in the 3rd State Central Hospital of Mongolia.@*Objective@#To study the clinical features of the cerebral vasospasm and dopplerosonography parameters in the aSAH patients. @*Materials and Methods@#The methods, methodology and ethics of the research work were discussed at a Research meeting of Ethics Control Committee of the Mongolian National University of Medical Sciences held on December 22, 2017 (No2017 / 3-05), and the study was performed in accord with approval.</br> 60 patients with aSAH (hospitalized from 2017 to 2018 year) were enrolled in the case-control study. Informed consent were obtained from each participants. Clinical condition of participants was classified by Hunt-Hess scale (HHS). Cerebral vasospasm degree was graded by Lindegaard index.@*Results@#52.5% of the participants were men and 47.5% were women. Average age was 49.9±12. When clinical condition degree was compared to vasospasm grade it was revealed that amongst 1st degree of Hunt-Hess scale (HHS) group 11.1% of enrolled patients’ spasm was normal or had no spasm, while it was observed either 44.4% mild and moderate spasm. In the 2nd degree of HHS group: normal in 6.9%, mild in 3.4%, moderate in 86.2%, and severe spasm was in 3.4%. In the 3rd degree of HHS group, 11.1% had no spasm, moderate spasm was in 77.8%, and severe spasm was in 11.1%. In 4th degree of HHS group, 71.4% were with moderate spasm, 28.6% were with severe spasm (p = 0.001). </br> When the Hunt-Hess Scale was compared to the Sinus Rectus 1st degree of Hunt-Hess scale (HHS) group Sinus Rectus was normal for 22.2% patients, mild for 66.7% and severe for 11.1%. Though 4th and 5th degree of Hunt-Hess scale (HHS) groups’ Sinus Rectus mild for 7.1% normal, 50.0% mild and 42.9% severe (p=0.007). Thus whenever the clinical condition worsened the cerebral intracranial pressure was increasing.@*Conclusion@#aSAH patients clinical complication degree were directly associated with the cerebral vasospasm revealed by the transcranial dopplerosonography. Therefore, the evaluation of Hunt-Hess scale has an important significance in the prevention from clinical complications and in the selection of the appropriate treatment approaches for aSAH patients.

ABSTRACT

Background@#The effect of lipopolysaccharide (LPS) on valproic acid (VPA)-induced cell death was examined by using mouse RAW 264.7 macrophage cells. @*Materials and methods, results@#LPS inhibited the activation of caspase 3 and poly (ADP-ribose) polymerase (PARP) and prevented VPA-induced apoptosis. LPS inhibited VPA-induced p53 activation and pifithrin-α as a p53 inhibitor as well as LPS prevented VPA-induced apoptosis. LPS abolished the increase of Bax/Bcl-2 ratio, which is a critical indicator of p53-mediated mitochondrial damage, in response to VPA. The nuclear factor (NF)-κB inhibitors, Bay 11-7082 and parthenolide, abolished the preventive action of LPS on VPA-induced apoptosis. A series of toll-like receptor (TLR) ligands, Pam3CSK4, poly I:C, and CpG DNA as well as LPS prevented VPA-induced apoptosis. @*Conclusion@#Taken together, LPS was suggested to prevent VPA-induced apoptosis via activation of anti-apoptotic NF-κB and inhibition of pro-apoptotic p53 activation.

ABSTRACT

Introduction@#After central nervous system injury, microglia cells are activated to initiate inflammatory responses and release cytokines that beneficially or detrimentally affect surrounding cells. Lipopolysaccharide stimulates microglia cells and produce pro-inflammatory cytokines such as interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α. A dehydrocostus lactone (DDL) which is contained in medicinal plant, Saussurea lappa, is considered to have various health benefits in neurodegenerative diseases of central nervous system. </br> In this study, we aimed to investigate the anti-inflammatory effects of Dehydrocostus Lactone following lipopolysaccharide stimulation of microglial cells in vitro.@*Materials and Method@#The anti-inflammatory effects of dehydrocostus lactone were studied using lipopolysaccharide (LPS) stimulated murine microglia (BV2). BV2 were cultered in DMEM then three different doses (4µM, 8µM and 12µM) of DDL were added in the medium for 30 minutes respectively. Then BV2 were treated with 1 ng/ ml LPS for 24 hours to stimulate. The level of IL-1β, IL-6 and TNF-α were measured in 100µl of culturemedium supernatant by ELISA. Three different doses of DDL anti-inflammation groups (BV2+DDL+LPS), LPS-activated group (BV2+LPS) and control group (only BV2) were analysed. @*Results@#LPS-treated BV2 cells had increased IL-1β, IL-6 and TNF-α compared with those without LPS treatment. Pretreatment with dehydrocostus lactone prior to LPS treatment significantly decreased levels of IL-1β and TNF-α in a dose-dependent manner compared with LPS-treated BV2 cells and 4µM was the most effective anti-inflammatory dose of dehydrocostus lactone. As for IL-6, 12µM dehydrocostus lactone was the most effective anti-inflammatory dose, although all doses significantly decreased the level of IL-6, in a dose-dependent manner. @*Conclusion@#These results show that DDL decrease inflammation related IL-1β, IL-6 and TNF-α in a dose-dependent manner in microglia cells.

ABSTRACT

Introduction@#Valproic acid (VPA) has been used in the treatment of seizures and bipolar disorders. In the present study, we examined how VPA affected PI3K-Akt pathway in response to LPS by using mouse RAW 264.7 macrophage cells.@*Material and methods@#Mouse RAW 264.7 macrophage-like cells cultured and the cell viability checked by MTT and TUNEL assay. In addition, protein expression and protein interaction were detected by immune blotting and immune precipitation, respectively. TLR4 expression on cell surface studied by FACS analysis.@*Results@#The MTT and TUNEL assays demonstrated no significant difference between VPA at 2 mM treated and untreated control cells. VPA attenuated LPS-induced phosphorylation of phosphatidylinositol 3-kinase (PI3K) and Akt, but not nuclear factor (NF)-κB and mitogen activated protein kinases (MAPKs). There was no significant difference in the TLR4 expression on the cell surface between cells treated with or without VPA. VPA inhibited LPS-induced PI3K/Akt signal transduction in a dose dependent manner.@*Conclusion@#VPA at 2mM exhibits nontoxic effect in the RAW 264.7 cells. VPA down regulates LPS-induced phosphorylation of Akt via inhibition of PI3K activation.

ABSTRACT

Introduction@#Toll like receptors (TLRs) are a class of proteins that key role in the innate immune system. The SOCS1 and SHP2 proteins are negative-feed loop inhibitors of signaling of JAK/STAT and TLRs pathways.@*Purpose@#To determine negative regulator protein activation which is activated through TLR7 ligand/IFN-γ signal transduction in endothelial cells. @*Methods@#We used mouse aortic linear endothelial cell (END-D); protein expressio was detected by western blotting @*Results@#We analyzed a time dependent stimulation effects of negative regulator proteins stimulated by TLR7 ligand/IFN-γ in endothelial cell cultures. Imiquimod of 10 μg/ml treatment of 1 hr was followed by 100 ng/ml IFN-γ stimulation for 1-8hr to analysis of negative regulator SOCS1 and SHP2 protein expression. </br> In untreated cells, there was low activations of negative regulator SOCS1 and SHP2 proteins. IFN-γ stimulation alone had increased SOCS1 and SHP2 protein expressions, also imiquimod treatment highly <i>elevated</i> SOCS1 and SHP2 expressions. However imiquimod and IFN-γ doubled treatment have decreased activation of negative regulator SOCS1 and SHP2 proteins. These findings suggest SOCS1 and SHP2 proteins are inhibitors in the TLR7 ligand/IFN-γ signaling. @*Conclusion@#Negative regulators, SOCS1 and SHP2 strongly suppressed activations of TLR7 ligand/IFN-γ signaling

ABSTRACT

@#BACKGROUND: Toll like receptors (TLRs) are a class of proteins that key role in the innate immune system. TLR7 is expressed on monocytes, macrophages and dendritic cells, T cell, B cell and eosinophiles. TLR7, originally identified as recognizing imidaquinoline, loxibrine, broprimine and ssRNA, ssRNA viruses such as vesicular stomatitis virus, influenza A virus and human immunodefiency virus. It is known that virus ssRNA affects signaling molecule of IFN-y. Objective: To determine gene and protein activation of IFN-y signal transduction by TLR7 ligand in the endothelial cells. MATERIAL: In study we used mouse aortic linear endothelial cell which is cultured (END-D) in 5% heat- inactivated fetal calf serum (FCS), medium (DMEM) containing antibiotic mix(penicillin G, streptomycin, amphotericin B) at 37°C (5% CO2). Endothelial cells treated with synthetic IFN-γ and imiquimodligands, then the NO (nitric oxide) concentration in the supernatant is determined by Griess reagent. Endothelial cells are cultured in 6 well cell culture plate and in each well 2*104cells are expected to be grown for 24 hours of culture. Then, the cells are treated with synthetic IFN-γ and имиквимод ligand for 6 hours and the NO signaling gene activation iNOS mRNA expression which is induced by IFN-γ is determined by RT-qPCR. Endothelial cells are cultured in 12 well cell culture plate and in each well 2*104 cells are expected to be grown for 18 hours of culture. Then, the cells are treated with synthetic IFN-γ and imiquimodligands for 24 hours and the NO signaling protein iNOS expression which is induced by IFN-γ is determined by western blotting. The experiment was conducted as representation mean of at least three test results. The difference between statistical probabilities is determined by the “Students” t test. The p<0.01 value is assumed to be statistically different. RESULTS: TLR7 ligand imiquimodaugmented interferon gamma induced nitric oxide production TLR7 ligand imiquimodincreased interferon gamma induced iNOS mRNA gene expression. TLR7 ilgand imiquimodup-regulated interferon gamma induced iNOS protein expression. CONCLUSIONS: TLR7 ligand imiquimod augments IFN-γ signaling in the endothelial cells.

ABSTRACT

Charcot-Marie-Tooth disease (CMT) is a clinically and genetically heterogenous group of disorders. Useful classifi cation is still clinical and electrophysiological classifi cation that divides CMT into CMT type 1 - demyelinating form and CMT type 2 - axonal form. An intermediate type is also increasingly being determined. Inheritance can be autosomal dominant, X-linked and autosomal recessive (AR). In this review, we will focus on the clinical and/or electrophysiological findings and molecular genetics of ARCMT1 (CMT4). Ten genes, GDAP1, MTMR2, MTMR13, SH3TC2, NDRG1, EGR2, PRX, CTDP1, FGD4 and SAC3 have been identifi ed in the CMT4A, CMT4B1, CMT4B2, CMT4C, CMT4D, CMT4E, CMT4F, CCFDN, CMT4H and CMT4J types, respectively. In addition, susceptibility locus on chromosome 10q23 has been found for CMT4G disease. Molecular genetics of demyelinating ARCMT are large disabilities of proteins in Schwann cells and their functions (transcriptional factor, protein transport, protein sorting, intra/extra cellular compartments, signal transduction, cell division, and cell differentiation). It has been rising necessary requirements to defi ne clinical and genetic subtypes of the ARCMT1, prevent from disease, give reproductive and genetic counselling, and develop methods for reducing and clear disease risk factor.
