Abstract

BACKGROUND: The current biomarker diagnostic modality for acute coronary syndrome (ACS), cardiac troponin, has several limitations. Emerging studies showed that micro-RNA (miR)-133a was released from infarcted heart to circulation, yet the diagnostic value of miR-133a in ACS demonstrated a conflicting result. Therefore, this study was conducted to investigate the potency of plasma miR-133a as a biomarker candidate of ACS.METHODS: This was a case-controlled study, involving ACS and control subjects. The sociodemographic and clinical characteristics were assessed through medical records. A final of 39 ACS and 31 control subjects (consist of healthy and non-ACS subjects) passed the selection procedure by demonstrating a high purity of RNA. miR-133a from ACS and control subjects were detected by quantitative polymerase chain reaction (qPCR). Expression of miR-133a was evaluated for sensitivity and specificity as an ACS biomarker diagnostic using the receiver operating characteristic (ROC) curve.RESULTS: Plasma miR-133a expression was stably found in ACS subjects. The plasma miR-133a level was lower in ACS than in control subjects. miR-133a effectively distinguished ACS subjects from healthy subjects (AUC=0.911) and exhibited high diagnostic performance, with a sensitivity of 87.1% and specificity of 100% at a cut-off value of 44.035. In an extended model including both control subjects (healthy and non-ACS with comorbid conditions), miR-133a maintained diagnostic significance (AUC=0.874), showing sensitivity of 76.9% and specificity of 100% at a cut-off value of 11.69.CONCLUSION: Plasma miR-133a is significantly lower and effectively distinguishes ACS patients from both healthy individuals and non-ACS individuals with comorbid, with a cut-off value of 11.69. Therefore, plasma miR-133a is suggested to be a good candidate for diagnostic biomarkers of ACS.KEYWORDS: circulating miRNA, miRNA-133a, acute coronary syndrome, diagnostic biomarker

Abstract

BACKGROUND: Glaucoma can lead to irreversible blindness, but normotension glaucoma (NTG) often shows no early symptoms. However, to date, there is limited knowledge regarding the potential parameters for early detection. Therefore, in this study, various metabolic parameters and biomarkers which may contribute to NTG in metabolic syndrome (MetS) patients were evaluated.METHODS: A retrospective cross-sectional study was conducted in the National Cardiac Center Harapan Kita Hospital. Mets were confirmed following the IDF criteria. NTG was determined based on normal intraocular pressure (IOP) with a mean defect (MD) of the visual field, thinning of the retinal nerve fiber layer (RNFL), and enlargement of cup disc ratio (CDR) by ocular coherence tomography (OCT). Metabolic parameters results of waist circumference (WC), body weight, body height, body mass index (BMI), blood pressures, HbA1c, fasting blood glucose (FBG), lipid profiles; and biomarkers including thiobarbituric acid reactive substance (TBARS) and ferric reducing antioxidant power (FRAP), leptin, adiponectin, high-sensitivity C-reactive protein (hs-CRP), and endothelin-1 (ET-1) were analyzed. Statistical analysis was performed using comparative and correlative tests.RESULTS: From 29 subjects, 19 subjects (65.5%) were included in the NTG group and 10 subjects (34.5%) were included in the non-NTG group. In the NTG group, we found significant correlation between MD with systolic blood pressure (p=0.035); CDR with ET-1 (p=0.049); and CDR with adiponectin (p=0.010). The non-NTG group had a significant correlation between MD with BMI (p=0.043); CDR with LDL (p=0.042); and CDR with TG (p=0.031).CONCLUSION: There are correlation between adiponectin and ET-1 with NTG in MetS patients. Therefore, they might be considered as potential early detectors for NTG in MetS patients.KEYWORDS: normal tension glaucoma, metabolic syndrome, biomarker, endothelin-1, adiponectin

Abstract

BACKGROUND: Oral squamous cell carcinoma (OSCC) of the tongue is an aggressive cancer with a poor prognosis due to its resistance to standard treatments. Stenochlaena palustris, a medicinal fern containing bioactive compounds, has shown potential anticancer properties. However, there is a lack of studies addressing the effects of S. palustris ethanol extract (SPEE) on tongue cancer. This study examined the effects of SPEE on the cell viability and cell cycle of human squamous cell carcinoma (HSC)-3 tongue cancer cells.METHODS: SPEE was prepared with the maceration method. HSC-3 cells were treated with SPEE at concentrations of 100, 500, and 1000 µg/mL for 24 and 48 hours. Cell viability was measured with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Cell cycle analysis was performed using flow cytometer. Immunoblotting was used to measure amount of cell cycle regulators, protein 21 (p21) and protein 27 (p27).RESULTS: SPEE treatment led to a significant decrease in HSC-3 viable cells in a concentration- and time-dependent manner, with the most pronounced effect at higher concentration and prolonged treatment time. There was a slightly increase in the percentage of cells in the Sub-G1 phase in SPEE-treated group, meanwhile there was a significant increase in the percentage of cells in the G1-phase. Increased amount of p21 and p27 were observed in SPEE-treated group.CONCLUSION: SPEE significantly inhibited HSC-3 cell proliferation in a concentration- and time-dependent manner, primarily by inducing G1-phase cell cycle arrest through the upregulation of p21 and p27. Taken together, SPEE could be a potential anti-cancer agent for tongue cancer cell. KEYWORDS: Stenochlaena palustris, tongue cancer, cytotoxic, cell cycle arrest, HSC-3 cells, p21, p27

Abstract

BACKGROUND: The most influential susceptible gene associated with diabetes, transcription factor 7-like 2 (TCF7L2), has been observed in diverse populations. TCF7L2 influences type 2 diabetes risk through glucagon-like peptide 1 (GLP1) production. The presence of risk allele of TCF7L2 leads to the alteration of gene expression in pancreatic beta cells; however, how the mechanism is related with GLP1 remains unclear. This study was conducted to explore the variations of GLP1 increment and insulin secretion between individuals with and without diabetes risk allele of single nucleotide polymorphisms (SNPs) in TCF7L2.METHODS: A cross-sectional analytic study was conducted involving individuals subjects who harbored known variants of SNPs in the TCF7L2: heterozygote or mutant of rs12255372 (GT or TT), rs7903146 (CT or TT), rs10885406 (AG or GG); as well as control subjects with wild type of rs12255372 (GG), rs7903146 (CC), and rs10885406 (AA). Anthropometric parameters, blood glucose, insulin, and GLP1 were measured; and homeostasis model assessment-beta cell (HOMA-%B) index was calculated.RESULTS: The GLP1 increment response was higher in subjects carrying the diabetes risk allele (0.34±0.80 ng/mL) than those with the wild type (-0.04±0.57 ng/mL) (p=0.041). The HOMA-%B was reduced in subjects carrying the diabetes risk allele (71.64±24.72) than those with the wild type (103.23±68.00) (p=0.011). Among individuals carrying the diabetes risk allele, the likelihood of GLP1 increment with high response was twice as high (p=0.007), while the occurrence of low HOMA-%B was 1.47 more frequent (p=0.011).CONCLUSION: TCF7L2 polymorphisms were associated with the GLP1 increment response and reduced HOMA-%B, which might be potentially contributing to GLP1 resistance in patients with diabetes risk factors.KEYWORDS: diabetes risk, TCF7L2, GLP1, HOMA-%B

Abstract

BACKGROUND: Colorectal carcinoma (CRC), the third most common malignant disease worldwide, is associated with estrogen receptor β (ERβ) and interleukin-6 (IL-6). ERβ is known to down-regulate IL-6 in prostate cancer, lung carcinoma, and CRC cell lines; however, its effect on human with CRC remains unclear. Therefore, this study was conducted to investigate the association between ERβ and IL-6 expressions with the clinicopathological features of CRC.METHODS: This was an analytic observational study using 40 paraffin blocks of CRC patients. ERβ and IL-6 expression was measured by immunohistochemistry (IHC) staining. The percentage of immunoreactive tumor cell per 1000 cells was manually recorded and tumor differentiation as well as tumor infiltration were determined. Tumor differentiation was graded according to the World Health Organization (WHO) 2010 criteria, while tumor infiltration was defined based on the American Joint Committee on Cancer (AJCC) 8th edition.RESULTS: Fifty percent of samples were well-differentiated CRC, and 57.5% samples were T3 infiltration tumors. IHC staining showed 35.5% of samples were positive for ERβ expression, while 70.86% were positive for IL-6 expression. There were negative correlation of ERβ expression with tumor differentiation (p=0.018; r=-0.371), but no correlation with tumor infiltration (p=0.836) were found. There was no correlation between ERβ expression with IL-6 expression (p=0.154).CONCLUSION: There is statistically significant correlation between tumor differentiation and ERβ expression, wherein improved tumor differentiation is linked to higher levels of positive ERβ expression. However, there is no discernible relationship between IL-6 and tumor differentiation. These findings suggest that while IL-6 was involved in the growth of the tumor, ERβ expression might have an impact on tumor differentiation.KEYWORDS: colorectal carcinoma, estrogen receptor beta, interleukin-6, cell differentiation

Abstract

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by inflammation. The pathogenesis of SLE involves key proteins, including B cell-activating factor (BAFF) and the ubiquitin enzyme A20, both serving as negative regulators of inflammation and contributing to B cell homeostasis. In this review, focused on interventions directed at BAFF and the A20 enzyme, utilizing monoclonal antibodies either independently or in conjunction with conventional therapy for SLE patients.METHODS: A literature search was conducted on the PubMed platform by combining various terms, including "B-cells activating factor", "TNFAIP3 protein (human)", "therapeutics" or "drug therapy", and "lupus erythematosus, systemic" (limited to the last 10 years). From total of 104 articles discovered in thr search, the total number of articles collected after being filtered was 27 articles.RESULTS: Clinical development and evaluation have been conducted regarding the use of appropriate therapy for SLE patients. Selective BAFF inhibitor has been tested in clinical trials as a blocking agent in BAFF receptor (BAFF-R) and signaling nuclear factor-kappaB (NF-κB) by A20 bindings to inhibit the activation of autoreactive B cells. Just like other antimonoclonal therapies, BAFF and the A20 enzyme can be used as therapeutic targets with a single use or combined with the standard therapy in patients with SLE. In addition, the use of BAFF and A20 also shown to have safe side effects in patients with SLE. CONCLUSION: BAFF protein and A20 enzyme present promising therapeutic targets for managing autoimmune diseases like SLE. Therapeutic interventions can be administered individually or in conjunction with standard treatments.  KEYWORDS: systemic lupus erythematosus, therapeutic targets, BAFF, A20

Abstract

BACKGROUND: Nigella sativa has been known for its neuroprotective properties, while propofol is an anesthetic induction drug that has been widely used in the treatment of traumatic brain injury (TBI). To determine the effectiveness of both active ingredients, it is necessary to compare their neuroprotective effects. This study was performed since not many studies have compared the effect of propofol and Nigella sativa seeds ethanol extract (NSSEE) or their combination on histopathological features in TBI cases.METHODS: Thirty male rat models were divided into 5 groups. Four groups received TBI induction with the methods of Feeney’s weight drop model, while another group (control group) did not receive TBI induction. Groups with TBI induction, later received no treatment, treatment with 500 mg/kg NSSEE orally, 10 mg/kg propofol intravenously, or a combination of NSSEE and propofol. After 8 days, rats were euthanized by cervical dislocation. Subsequently, a craniotomy was performed to obtain brain samples. The brain sample was placed in 10% neutral buffered formalin for histopathological examination, which includes brain hemorrhage, congestion, inflammatory cells, necrosis, apoptosis, and degeneration.RESULTS: The present study found that NSSEE showed greater efficacy in histopathological features (brain hemorrhage, congestion, inflammatory cells, necrosis, apoptosis, and degeneration) in rat models with TBI compared to propofol or a combination of propofol and NSSEE.CONCLUSION: NSSEE has superior potential compared to propofol and the combination of both in providing neuroprotection in TBI cases.KEYWORDS: traumatic brain injury, propofol, Nigella sativa seeds ethanol extract, histopathology, neuroprotective

Abstract

Diabetes mellitus (DM) is a chronic endocrine and metabolic disease indicated by the presence of hyperglycemia. It has been known that hyperglycemia and oxidative stress are the main culprit of all DM complications, including macrovascular complications. As a byproduct of lipid, protein, and carbohydrate metabolism, methylglyoxal (MGO) is a highly reactive substance which plays a positive signaling role in helping cells regain redox balance under oxidative stress circumstances. DM-related problems lead to an excess of mitochondrial superoxide in the heart and big and small vascular endothelial cells. Elevated intracellular reactive oxygen species induce impaired angiogenesis in reaction to ischemia, trigger several proinflammatory pathways, and result in enduring epigenetic modifications that propel the continuous expression of proinflammatory genes even after glucose levels return to normal. Over time, the significance of the extremely quick advanced glycation end-products (AGE) production caused by the extremely reactive MGO has been clarified. It is now evident that MGO causes vascular tissue to react maladaptively. Glyoxalase 1 (GLO1) is the primary enzyme in an organism's enzymatic glyoxalase defense mechanism, which converts MGO to D-lactate in order to counteract the harmful effects of MGO. Understanding the role of the MGO–GLO1 pathway in the etiology of vascular disease in diabetes has advanced significantly. Therefore, it can be summarized that vascular damage are linked to diabetes. The AGE precursor MGO are important in determining the connection between diabetes and vascular damage. MGO and AGEs play a role in several phases of the development of diabetes complications. MGO and AGEs may be useful therapeutic targets for diabetes's macrovascular problems.KEYWORDS: hyperglycemia, AGE, methylglyoxal, glyoxalase, D-lactate, gluthatione, oxidative stress

Abstract

BACKGROUND: The prevalence of obesity, or an excessive fat accumulation, is keep increasing. In obesity, inflammation can be induced by leaky gut due to the intestinal tight junction barrier dysfunction. Zonula occludens-1 (ZO-1) plays a role in developing intestinal tight junction barrier dysfunction and gut microbiota imbalance, thus promote the translocation of bacterial endotoxin characterized by lipopolysaccharide (LPS) into circulation. Black rice extract (BRE) has been known to have anti-inflammatory property. This study was conducted to investigate the effect of BRE on body weight (BW), waist circumference (WC), body mass index (BMI), ZO-1 and LPS of obese patients.METHODS: Twenty-three male subjects were divided into non-obese group (NOG), obese group (COG) and BRE-obese group (BOG). Subjects in BOG received a daily dose of 5.6 g/day BRE for 4 weeks. BW, WC and BMI, serum ZO-1 and LPS were measured before and after treatment.RESULTS: BRE was prepared successfully and free from microbial contamination. Treatment of BRE for 4 weeks reduce BW (95.40±5.78 vs. 94.59±6.00 kg, p=0.043), WC (109.25±3.55 vs. 107.50±3.46 cm, p=0.000) BMI (32.65±1.86 vs. 32.18±1.80, p=0.000) and LPS (222.27±38.63 vs. 131.63±9.70 ng/mL, p=0.020) of obese subjects. The pre-post ZO-1 levels in all groups were not significantly different (p>0.05).CONCLUSION: Treatment of 5.6 gr BRE daily for four weeks can reduce BW, WC, BMI and serum LPS, but not serum ZO-1 in obese patients. Therefore, BRE may reduce inflammation in obesity.KEYWORDS: black rice, obesity, BW, WC, BMI, LPS, ZO-1

Abstract

BACKGROUND: Numerous inflammatory diseases are linked to increased endothelial permeability through the nitric oxide (NO) flux in endothelial cells. Luteolin has in vitro and in vivo anti-inflammatory properties and has been reported to reduce endothelial permeability. However, the exact mechanism/s are yet to be determined. Thus, the present study was conducted to investigate the effects of luteolin in reducing endothelial permeability in vitro using bradykinin (BK) or sodium nitroprusside (SNP) through the NO pathway and the NO radical scavenging property of luteolin.METHODS: Human umbilical vein endothelial cells (HUVECs) in the treatment groups were dosed with luteolin at 5, 10, and 25 µM concentrations and allowed to incubate for one hour prior to induction. The L-NAME or HOE 140 were administered prior to the induction of BK or SNP in HUVECs. The NO radical scavenging test, the nitrite determination assay using L-NAME as antagonist, and the in vitro vascular permeability testing using HOE 140 as antagonist were performed.RESULTS: Endothelial permeability was decreased dose-dependently by 5, 10, and 25 µM luteolin in vitro via lowering NO generation. In comparison to HOE 140, luteolin suppressed the enhanced endothelial permeability more effectively. The suppression was 98.02% by 25 µM luteolin compared to HOE 140 94.05%. It was also discovered that luteolin, when incubated with SNP in a dose-dependent manner, possessed potent NO radical scavenging activities.CONCLUSION: The current data demonstrated luteolin's ability to scavenge NO radicals and significantly decrease endothelial permeability through the NO route. Thus, in complementary medicine, luteolin might be potential to improve endothelial permeability suppressor in reducing inflammation.KEYWORDS: luteolin, endothelial permeability, NO, scavenging property, HUVECs
