Abstract

Background: Indonesia is the second-highest country with hepatitis B cases in the South East Asian region. Clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR associated protein 12 (Cas12) could be developed as a diagnostic tool to detect hepatitis B infection. This study was aimed to develop a diagnostic method for hepatitis B virus by designing CRISPR target-based single-guide RNA (sgRNA).Materials and method: The preCore/Core-gene sequences of hepatitis B virus were collected from the National Center for Biotechnology Information (NCBI) website. The selected sequence was submitted to Cas Designer and CRISPOR tools to design sgRNA. The resulting sgRNA was cloned in silico into an expression vector using Benchling software.Results: The 23-nucleotide sequence 5'- GTAGTCAGTTATGTCAATGTTAA-3’ had 30% GC content, 68.3 out-of-frame and 76 predicted efficiencies. This sequence had no mismatch based on analysis.Conclusion: This preliminary study will help design a CRISPR-based diagnostic kit for the detection of hepatitis B virus in Indonesia. However, further in vitro and in vivo studies are required to demonstrate its potential and efficiency.Keywords: CRISPR-Cas12b, diagnostic, HBV, sgRNA

Abstract

Background: Klebsiella pneumoniae is one of the bacteria that causes pneumonia infection. Even though the number of pneumonia cases is relatively high and has become a global problem, there is still no vaccine available to prevent this disease. This study was aimed to design a multi-epitope vaccine design through an in silico approach, against K. pneumoniae.Materials and method: Vaccine candidate was constructed based on proteins of K. pneumoniae. These proteins were analyzed to identify the antigens sequence for multi-epitope vaccine design. The constructed vaccine was predicted for allergenicity, toxicity, population coverage, and its physicochemical properties. The vaccine structure was then docked with the toll like receptor 2 (TLR2) molecule to show the interaction. Expression analysis and cloning of the constructed vaccine was carried out in the pET-28a vector using SnapGene.Results: The vaccine was 567 amino acids long, consisting of Cholera Toxin Subunit B as an adjuvant, 6 B-cell epitopes, 11 cytotoxic T-cell epitopes, and 10 helper T-cell epitopes connected with the appropriate linker. Epitopes analysis showed that the vaccine will be a non-toxic, has high antigenicity, but non-allergenic. The vaccine was predicted to be stable, hydrophilic, and had a low risk of triggering autoimmune response. The vaccine molecule was compatible to humans TLR2 molecule. Furthermore, visualization of the candidate vaccine protein on pET-28a showed that the vaccine protein might be expressed correctly.Conclusion: The construction of multi-epitope vaccine has been developed, which might be a good vaccine candidate, containing 6 B-cell epitopes, 11 CTL epitopes, and 10 HTL epitopes. The construct may help scientists to experimentally formulate multi-epitope vaccine against K. pneumoniae in the future.Keywords: in silico, Klebsiella pneumoniae, multi-epitope, vaccine

Abstract

Background: Cerebellum is one of the vital components of the brain that will be affected by ischemia-reperfusion (IR) injury. IR injury will increase free radicals, which in turn can trigger apoptosis and cell death. Therefore, this study was conducted to examine the effect of chlorogenic acid administration on apoptosis and the number of cells in the cerebellum of rats with global ischemic transients.Materials and methods: Wistar rats were divided into five groups: sham-operated (C1), IR (C2), IR + 15 mg/kgBW chlorogenic acid (T1), IR + 30 mg/kgBW chlorogenic acid (T2), and IR + 60 mg/kgBW chlorogenic acid (T3). C2, T1, T2, and T3 groups received bilateral common carotid occlusion (BCCO) surgery to induce IR injury. Thirty minutes after BCCO surgery, T1, T2, and T3 rats were administered chlorogenic acid in various doses intraperitoneally. RNA extraction and real-time polymerase chain reaction (PCR) measurements were then performed on NeuN, Bcl2, Bax, caspase 3, as well as on GAPDH as housekeeping genes.Results: There were significant differences in NeuN expressions between groups, with the highest expression shown in C1 followed by T3. Bcl2 expressions were also significantly different between groups, and rats in C1 and T3 showed to be significantly higher compared to C2, while T1 was significantly lower than C1. However, Bax and caspase 3 expressions showed no significant differences.Conclusion: Chlorogenic acid in 60 mg/kgBW dose increases NeuN expression and Bcl2 mRNA expression after transient global ischemia. These increases might correlate with the heightened level of protection against apoptosis in the cerebellum, hence showing its potential in protecting neuron cells.Keywords: transient global ischemia, chlorogenic acid, cerebellum, apoptosis

Abstract

Mesenchymal stem cells (MSCs) are widely recognized in cell treatment due to their capacity to secrete trophic factors, differentiate multipotent, and self-renew. Although there is growing evidence that MSCs have therapeutic benefits in various clinical settings, these cells eventually lose their ability to regenerate as they age, which increases cellular dysfunction. Several factors may affect MSCs aging, such as culture dimensions, cryopreservation process, and long-term expansion. Traditional two-dimensional (2D) culture conditions lack the complexities required to recreate MSCs in their natural environment. Meanwhile, three-dimensional (3D) culture mimics the niche, dynamic, and specialized microenvironments of the cells in vivo. The most used storage technique for MSCs, cryopreservation, requires a very low temperature reduction, which stresses cells and can cause the release of pro-inflammatory cytokines. For the utilization of MSCs in therapeutic applications, an in vitro expansion technique is required. Repeated expansion may reduce proliferative capacity, disrupts cellular shape, and impairs the somatic cell function of MSCs. Various processes and techniques may influence MSCs leading to cell aging. One of the culture methods, 3D culture, is shown to reduce the factors that will compromise the therapeutic effects of MSCs, especially cell senescence. The effect of culture dimensions, cryopreservation, and long-term expansion on cell senescence will be discussed in this review article.Keywords: cell aging, mesenchymal stem cell, 3D culture, cell senescence, cryopreservation, long-term expansion

Abstract

Background: Doxorubicin (DOX), an efficacious chemotherapy drug is compromised by cardiotoxicity, myelosuppression, and hepatotoxicity. Due to the limited success of current treatments for DOX toxicity, there is a pressing need to explore alternative medical interventions, particularly from plant sources. This study was conducted to investigate the potential protective effect of ethanolic extract of Andrographis paniculata leaves (EEAP) against DOX-induced cardiac inflammation, liver toxicity, and anemia.Materials and methods: Sprague-Dawley rats were intraperitoneally injected with DOX at a total dose of 16 mg/kgBW. EEAP was administered orally for 4 weeks at doses of 125, 250, and 500 mg/kgBW/day according to the assigned treatment groups. The mRNA expression levels of interleukin-1β (IL-1β) and nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 (NLRP3) in the heart tissue, along with the concentrations of nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB) and calcium level were examined. Additionally, the hematological parameters (including hematocrit, hemoglobin and red blood cells (RBCs)), aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), and malondialdehyde (MDA) levels in blood were also analyzed.Results: EEAP dose-dependently decreased the mRNA expressions of IL-1β (p<0.05), tended to decrease mRNA expression of NLRP3 and the concentrations of NFκB and calcium in heart tissue compared with the DOX-only group. Additionally, EEAP dose-dependently decreased ALP values (p<0.0001) and tended to improve hematological parameters, as well as AST and MDA levels in serum.Conclusion: This extract may prevent DOX-induced cardiac inflammation, anemia, and hepatotoxicity. However, further studies are needed to confirm these findings, including the efficacy profile of the extract in cancer rats treated with DOX.Keywords: doxorubicin, Andrographis paniculata, inflammation, anemia, hepatotoxicity, herbal medicine

Abstract

Background: Percutaneous atrial septal defect (ASD) closure is one of therapeutic options for patients with a suitable ASD anatomy, however in developing countries, the exact figure and procedural characteristics remain unknown. Therefore, this study was conducted to identify the failure rate and procedural predictors of the percutaneous ASD closure.Materials and methods: A retrospective study using a database of all patients undergoing percutaneous ASD closure was conducted between March 2010 to November 2023. Patients who developed a pulmonary hypertensive crisis during the procedure were excluded. Procedural and echocardiographic parameter were measured and analyzed.Results: A total of 112 samples were included in this study, 74.1% were female and 55.36% were pediatric patients. The failure rate was 12.5% (n=14) with diameter index was higher in the failed group. Unpaired T-test revealed that ASD size was one of the predictor failure in pediatric patients (mean diameter: 24.7±6.46 mm vs. 16.36±5.94 mm, p=0.001). There were no statistically significant variations in rim diameters, while compared with all patients with appropriate rims (rim ≥7mm), the failure rate was higher in patients with two rims measuring between 5.9 and 6.9 mm and rims less than 5 mm. Two patients presented with device embolization and required surgical device removal.Conclusion: The failure rate of percutaneous ASD closure was 12.5%. A larger ASD increases the risk of failure of percutaneous closure in pediatric patients. Furthermore, patient with 5-6.9 mm on two or more rims as well as those with rim less than 5 mm, have a higher failure rate.Keywords: secundum atrial septal defect, percutaneous closure, failure rate

Abstract

Obesity, lack of physical activity, and genetic predisposition might play a pivotal role in pathogenesis of metabolic syndrome. Cardiac function alteration including hemodynamic changes, contractility function, arrhythmia, and cellular respiratory function, might happen due to chronic condition in metabolic syndrome. Insulin resistance, neurohormonal activation and chronic inflammation might contribute to these changes. Cardiomyocyte had capabilities to adapt from these abnormalities, one of them is the activation of cellular pathway to resist cardiac injury from metabolic syndrome. This molecular pathway involves three proteins, including AMP-activated protein kinase (AMPK), sirtuin-1 (SIRT1) and peroxisome proliferator-activated receptor γ coactivator-α (PGC-1α). The aim of this narrative review is to elucidate role of AMPK, SIRT1, and PGC-1α in cardiac adaptation against cardiac dysfunction in metabolic syndrome. AMPK, SIRT-1, and PGC-1α contribute to adapt and to repair the cardiac injury resulting from celullar and mechanical stress from metabolic syndrome and prevent cardiac remodeling event. Several pathological events, such as insulin resistance, induce alteration of switching energy fuel to the heart, causing cardiomyocte to rely on glucose metabolism and lipotoxicity, leading to damages of cardiomyocyte through reactive oxygen species (ROS) generation and lipid peroxidation. Increase of ROS promotes cardiac injury followed by necrotic and apoptotic events. AMPK, SIRT1, and PGC-1α act as cardioprotector molecule against metabolic syndrome insults to several mechanism such as: AMPK play role as counter act of lipotoxicity and insulin resistance through increasing insulin sensitivity and regulate redox reaction. SIRT1 plays role in regulating apoptotic genes and PGC-1α repairs cardiac fuel sources. Activation of AMPK/SIRT1/PGC-1α prevent cardiac remodeling due to metabolic syndrome by increasing insulin sensitivity, increases mitochondrial biogenesis and reduce pro-apoptotic signals in cardiomyocte.Keywords: AMPK/SIRT1/PGC-α, cardiac remodeling, metabolic syndrome

Abstract

Background: Thyroid hormone metabolism is linked to iron metabolism. Thyroperoxidase, a key enzyme in the biosynthesis of thyroid hormones, is iron-dependent. Thus, iron deficiency might be the primary cause of hypothyroidism. Copper is another trace element that has been linked to thyroid status. Copper regulates excessive thyroxine (T4) absorption and reduces cell damage during thyroid hormone synthesis. The present study clarified the possible correlations between iron and copper levels as well as total iron binding capacity (TIBC) and triiodothyronine (T3), T4, as well as thyroid-stimulating hormone (TSH) levels in healthy and hypothyroid subjects.Materials and methods: Thirty-five healthy subjects and 35 hypothyroid subjects were included in this study. Serum T3, T4, and TSH levels were measured using the enzyme linked fluorescence assay. Serum iron levels and TIBC were estimated using ferrozine/magnesium carbonate method, while serum copper levels were estimated using colorimetric method.Results: Copper levels were not significantly different between healthy and hypothyroid subjects. Iron and T4 levels were significantly lower in hypothyroid subjects compared with those in healthy subjects, while TIBC and TSH levels were significantly higher. There was no significant correlation between copper levels and T3, T4, and TSH levels.Conclusion: There were inverse correlations between TIBC and T4 as well as iron levels, and there was no significant correlation between copper levels and all thyroid function parameters. Routine examination of iron levels and thyroid function is highly recommended for early diagnosis and therapy of hypothyroidism.Keywords: total iron binding capacity, iron, copper, hypothyroidism
