Abstract

BACKGROUND: Signaling pathways contributing to cholesterol efflux and inhibitory inflammation in atherosclerosis that has not been explored is the liver X receptor (LXR). Catechin as LXR agonist influences the expression of Niemann-pick C1 like 1 (NPC1L1) protein transporter that triggers the inhibition of cholesterol absorption. This study aimed to examine the effect of Catechins on the expression of intestinal transporters: NPC1L1, ATP-binding cassete-proteins G5 (ABCG5) and G8 (ABCG8).METHODS: Twenty-five experimental animals were divided into five treatment groups, with 5 rats in each group. The groups were normal diet rats (group 1), high fat diets-induced rats (group 2), high fat diets-induced rats treated with 30 mg/kg body weight (BW) of Catechins (group 3), high fat diets-induced rats treated with 60 mg/kg BW of Catechins (group 4), and high fat diets-induced rats treated with 120 mg/kg BW of Catechins (group 5). After one-month, all rats were sacrificed, blood and intestine were collected. Lipid profile were determined enzymatically, mRNA levels were determined by reversetranscriptase polymerase chain reaction (RT-PCR), while the expression of protein transporter were determined by immunohistochemistry.RESULTS: Catechins treatment decreased the expression of NPC1L1, but increased the expression of ABCG5 and ABG8.CONCLUSION: Catechins can be developed as a candidate for NPC1L1 inhibitor to mediate the inhibiting absorption of intestinal cholesterol, therefore increasing the inhibitory effect of atherogenesis.KEYWORDS: ABCG5, ABCG8, aterogenesis, Catechins, green tea, NPC1L1

Abstract

BACKGROUND: Hyperglycemia is one of the most common endocrine complications in children with β thalassemia major. Though the current diagnostic marker either requires fasting, has low reproducibility, or it is not an accurate for thalassemia patients. Glycated albumin (GA) is a quick and easy alternative marker for hyperglycemia detection and monitoring of glycemic control. However to date, no studies have analyzed the role of GA value in detection of hyperglycemia in children with thalassemia major. This study analyzed the value of GA as an alternative screening marker for hyperglycemia detection in children with β thalassemia major.METHODS: A single-blind prospective diagnostic test was conducted in 9 to 18 years old children with β thalassemia major and who were treated at the Dr. Moewardi Regional General Hospital between October 1, 2018 and December 31, 2019. In a single, fasted study visit, height, weight, fasting blood glucose (FPG), GA, oral glucose tolerance test (OGTT) were measured. The area under a receiver operating characteristic curve (AUC) was used to determine the cut-off value at which hyperglycemia prediction (OGTT ≥140 mg/dL) display optimal sensitivity and specificity. RESULTS: Among the 53 children with β thalassemia major, 1 (1.9%) had diabetes mellitus and 4 (7.5%) had prediabetes based on their OGTT values. The median GA value in this study was 10.9% (range: 7.6–12.4%). GA had a low AUC (0.646, p=0.287) for hyperglycemia detection in pediatric patients with β thalassemia major. At a cut-off of 11.45%, GA demonstrated 60% sensitivity and 60.4% specificity.CONCLUSION: GA cannot be used as an alternative marker for hyperglycemia detection in children with β thalassemia major.KEYWORDS: hyperglycemia, diabetes mellitus, prediabetes, β thalassemia major, glycated albumin

Abstract

BACKGROUND: Posterior capsule opacification (PCO) often occurs after cataract surgery. Metformin has been known to have an ability to inhibit fibrosis. This study aimed to investigate the effects of metformin on cell contractility, collagen deposition and degradation in human lens epithelial cells (HLEC) of cataract patients.METHODS: HLEC were isolated from the anterior lens capsule of patients undergoing cataract surgery. The HLEC culture was carried out using explant culture technique. The in vitro PCO model was created by scratching technique on HLEC cultures. The treatment groups were given 0.1, 0.5 and 1 mM metformin, respectively, while the control group were given 10% fetal bovine serum (FBS). On the 7th day after scratching technique, the collagen deposition, collagen degradation and cell contractility were evaluated.RESULTS: Collagen deposition in HLEC was significantly reduced after given 0.1 mM, 0.5 mM and 1 mM metformin (17.92±6.16 mg/mL, 12.92±4.31 mg/mL, 11.25±5.30 mg/mL, respectively), compared to the control group (31.46±7.52 μg/mL, p=0.002). Collagen degradation significantly was increased in the 0.1 mM, 0.5 mM and 1 mM metformin groups (4.77±9.27 mg/mL, 6.59±1.16 mg/mL, 6.35±1.90 mg/mL, respectively) compared to the control group (2.21±2.78 μg/mL, p=0.002). While, collagen contractility in HLEC was significantly reduced in 0.1mM, 0.5mM and 1 mM metformin groups (16.39±3.89%, 13.89±2.59%, 11.93±2.44%, respectively), compared to the control group (44.25±4.95%, p=0.000).CONCLUSION: Metformin reduced collagen deposition and contractility, but increased collagen degradation in HLEC of cataract patients through mechanism of extracellular matrix remodeling.KEYWORDS: metformin, human lens epithelial cell, fibrosis

Abstract

BACKGROUND: Sepsis is still leading cause of death in critically ill children. Early recognition of sepsis and treatments are needed to reduce its mortality. The use of citrullinated Histone H3 (Cit-H3) as an early sepsis marker and outcome predictor has been validated in previous studies among adults. However, only one study in pediatric meningococcal sepsis was reported with contradictory results. This study aims to determine Cit-H3 levels in pediatric clinical sepsis and analyze its association with sepsis severity and survival rate.METHODS: A prospective observational cohort study involving 67 pediatric subjects clinically diagnosed with sepsis was conducted. Cit-H3 levels, Pediatric Logistic Organ Dysfunction-2 (PELOD-2) score, and Pediatric Sequential Organ Failure Assessment (pSOFA) score were assessed at the time of diagnosis (0-hour) and 48 hours later. Pearson Correlation test was used to determine the correlation between Cit-H3 levels with PELOD-2 and pSOFA scores and receiver operating curve to find the cut-off of Cit-H3 levels on clinical sepsis patients.RESULTS: Among clinically sepsis patients, the median Cit-H3 level was 1,210 (800-32,160) ng/mL, with optimal cut-off point ≥1200 ng/mL (sensitivity 83.3% and specificity 75.7%) to discriminate sepsis. The median Cit-H3 levels at 0-hour were lower in survivor compared to non-survivor group (p=0.016). Cit-H3 level was able to predict mortality with optimal cut-off point ≥1,200 ng/mL, sensitivity 72.2% and specificity 57.1% (AUC of 69.2%; p=0.017). Using survival analysis, Cit-H3 was significantly associated with the mortality rate (p=0.023; hazard ratio of 3.45).CONCLUSION: Cit-H3 level could be potential to predict pediatric sepsis events and its outcome.KEYWORDS: citrullinated histone H3, neutrophil extracellular traps, pediatric sepsis, PELOD-2 score, pSOFA score, survival

Abstract

BACKGROUND: Mitochondria became a driving force in evolution due to their ability to manufacture adenosine triphosphate (ATP) through respiration. The functioning of mitochondria within eukaryotic cells has evolved dramatically as a result of evolution. Recent research has revealed mitochondria form plasticity to keep the cell's needs and function.CONTENT: Mitochondria have long been regarded as the cell's "powerhouse," providing energy for cell metabolism through oxidative phosphorylation (OXPHOS). A lot of physiological processes were known to be mediated by mitochondria including immunity and autophagy, cell death mechanism, and stem cell reprogramming. Mitochondria can change their shape to form a tubular network that is controlled by fission and fusion processes. Mitochondrial dynamics is the equilibrium between these two opposing processes that regulates mitochondrial number, size, and positioning within the cytoplasm.SUMMARY: All of these discoveries opened up new research avenues and revealed new targets for targeted medication development. Calorie restriction, and the mimetic agents were developed to increase mitochondria biogenesis to improve human lifespan.KEYWORDS: mitochondria, metabolism, homeostasis, stress response, aging, epigenetic

Abstract

BACKGROUND: One of the hormones that plays a role in glucose metabolism of Type 2 Diabetes Mellitus (T2DM) is melatonin. Its genetic variation is believed to play a significant role in the pathophysiology of obese and non-obese T2DM. The role of MTNR1B (melatonin receptor coding gene) and SLC2A1 (Glucose transporter 1/GLUT 1 transporter coding gene) on the risk of obese and non-obese T2DM patients is controversial. This study aims to analyze the association between the rs10830963 MTNR1B and rs841853 SLC2A1 polymorphism to the risk of Javanese obese T2DM.METHODS: This was a cross-sectional study that involved 107 Javanese T2DM patients from primary heath care in Semarang. Furthermore, obese T2DM was defined by a body mass index (BMI) more than 25 kg/m2. The genetic variations examined were rs10830963 MTNR1B and rs841853 SLC2A1 polymorphism by PCR-RFLP methods. Blood biochemistry parameters were also examined. Allele and genotype frequencies of rs10830963 MTNR1B and rs841853 SLC2A1 polymorphisms were analyzed using the x2 test with p≤0.05 and 95% CI.RESULTS: There was a significant association between rs10830963 MTNR1B polymorphisms in obese and nonobese T2DM (p=0.044) and the CG genotype increased the risk of obese T2DM. Furthermore, the allele and genotype frequency of rs841853 SLC2A1 polymorphism in both group had no significant difference, with a p=0.756 and p=0.802, respectively. There was also no significant difference in the biochemical parameters' in both groups of the two genetic variants studied.CONCLUSION: The rs10830963 MTNR1B polymorphism is associated with the risk of obesity in Javanese T2DM patients but not for the rs841853 SLC2A1 polymorphism.KEYWORDS: polymorphism, MTNR1B, SLC2A1, obese, diabetes mellitus

Abstract

BACKGROUND: The absence of potential biomarkers to detect the metastatic process at an early stage will consequently delay colorectal cancer (CRC) treatment. Some biomarkers including β-Catenin, E-Cadherin and N-Cadherin have been suggested as potential markers. However, there were opposite reports regarding expressions of these markers. Therefore, current study was conducted using CRC cell lines for early stage (SW-480 cells) and late stage (HCT-116 cells) of CRC.METHODS: SW-480 and HCT-116 cells were cultured and seeded on coverslip glasses for immunofluorescence staining to detect β-Catenin, E-cadherin, and N-cadherin. Expressions of β-Catenin, E-cadherin, and N-cadherin were observed and documented under a fluorescent microscope and analyzed with Image J software. Measured results were then statistically analyzed. RESULTS: All β-catenin, E-Cadherin and N-Cadherin expressions were observed in SW-480 and HCT-116 cells. β-catenin MFI averages of SW-480 (47.157±3.479) and HCT-116 (47.240±4.107) cells were similar. E-Cadherin MFI average of SW-480 cells (45.104±4.107) was higher than the one of HCT-116 cells (40.191±3.702). N-Cadherin MFI average of HCT-116 cells (43.702±8.219) was significantly higher (p=0.009) than the one of SW-480 cells (72.506±5.297).CONCLUSION: Taken together, N-Cadherin could be suggested as an important metastasis marker in CRC since the N-Cadherin expression was significantly higher in HCT-116 cells as the late-stage CRC model than SW-480 as the early-stage of CRC model. Further research is still needed by comparing several biomarkers from various clinical samples at all clinical stages of CRC.KEYWORDS: CRC, β-Catenin, E-Cadherin, N-Cadherin, Metastasis, Biomarker

Abstract

BACKGROUND: Single nucleotide variations (SNV) have been mapped to be associated with several human conditions and diseases. To validate the association between SNV to certain human traits or diseases, a large number of subjects must be included. Thus, in need of a fast, relatively economic, and reliable genotyping method. This can be achieved through the use of tetra-primer amplification refractory mutation system polymerase chain reaction (Tetra-primer ARMS PCR). This study reports strategy to develop Tetra-primer ARMS PCR-based genotyping of CHRNA3 rs8040868.METHODS: The optimization of Tetra-primer ARMS PCR was done through these steps: identification of gene sequence and position of single mutation; designing outer and inner PCR primers; amplification of target gene fragments through PCR by using outer primer; confirming genotype of the PCR product by using sequencing; determining an optimum ratio of outer and inner primer; and determining optimum annealing temperature and cycles for the PCR program. The PCR products were run in 2% gel agarose electrophoresis and visualized under UV illumination.RESULTS: Outer and inner primer ratio of 1:3 with annealing temperature of 64.4°C and 40x cycles was found to be the most optimum condition. Tetra-primer ARMS PCR was able to confirm the results of the DNA sequence of 2 samples, confirming wild-type variants (TT allele) and the heterozygous mutant (CT allele).CONCLUSION: Tetra-primer ARMS PCR was able to genotype rs8040868 of the CHRNA3 gene.KEYWORDS: tetra-primer ARMS PCR, CHRNA3, rs8040868, genotyping

Abstract

BACKGROUND: Coronary artery disease (CAD) remains as the world number one cause of morbidity and mortality. Endothelial progenitor cells (EPCs) are known to be involved in vascular biology. Current review briefly summarizes the basics of EPCs and its clinical use in CAD.CONTENT: EPCs were firstly isolated in 1997 and involved in neovascularization. Further evidence defined EPCs into two distinguishable groups, namely: myeloid angiogenic cells (MACs) and endothelial colony forming cells (ECFCs). Common cardiovascular drugs, statin, angiotensin-converting enzyme (ACE) inhibitor, and their combinations, showed beneficial effects on EPCs. Likewise, the incorporation of EPCs upon CAD intervention management had been recently studied. Intramyocardial EPCs implementation and anti-CD34 antibody-coated stents could provide a promising option for refractory symptoms in CAD.SUMMARY: Association between EPCs and CAD is very dynamic and complex. EPCs could serve as both therapeutic target and agent in CAD patients. Subsequently, a universal definition of EPCs is needed for greater research in the future.KEYWORDS: atherosclerosis, coronary artery disease, endothelial progenitor cells, neovascularization

Abstract

BACKGROUND: Psoriasis is an autoimmune disease involving genetic-environmental factors. Human Leukocyte Antigen (HLA)-Cw6 allele is the main genetic risk factor of psoriasis, but its prevalence varies widely. HLA-Cw6 allele correlates with psoriasis clinical type and treatment responses. Narrowband ultraviolet B (NB-UVB) and methotrexate (MTX) are effective psoriasis treatments but their association with HLA-Cw6 allele has not been identified. The study aims to determine the association between HLA-Cw6 allele expression, NB-UVB, and MTX treatment responses in Javanese-Indonesian psoriasis subjects.METHODS: Ninety Javanese-Indonesian psoriasis subjects were recruited in this study, 45 subjects were treated using NB UVB, while the other 45 subjects were treated using MTX, respectively, for 12 weeks. The psoriasis diagnosis and treatment responses were evaluated by dermatologists using Psoriasis Area Severity Index (PASI) score. The HLA-Cw6 allele was examined using the single-specific-primer polymerase chain reaction method. Fisher's Exact and Chi-square tests were employed, where p-value<0.05 was considered of significant association.RESULTS: The HLA-Cw6 allele positivity was identified in 23 psoriasis subjects (25.56%), while the other 67 subjects expressed HLA-Cw6 allele negative (74.44%). Female with HLA-Cw6 allele positivity who did not have comorbid disease show good response to NB-UVB than MTX. Meanwhile, subjects who were treated with MTX showed no association between therapeutic response and HLA-Cw6. HLA-Cw6 status was not correlated with the onset of psoriasis, family history, and comorbid diseases in all subjects.CONCLUSION: HLA-Cw6 allele expression is more associated with good NB-UVB treatment response than with MTX treatment response in female Javanese-Indonesian psoriasis subjects without comorbid disease.KEYWORDS: HLA-Cw6, narrowband ultraviolet B, methotrexate, Javanese, psoriasis
