Abstract

Thyroid peroxidase (TPO) is a crucial enzyme in the biosynthesis of thyroid hormones, catalyzing the iodination of tyrosine residues in thyroglobulin and the coupling of iodotyrosines to form thyroxine (T4) and triiodothyronine (T3). Propylthiouracil (PTU) is an antithyroid drug commonly used to manage hyperthyroidism by inhibiting TPO. Understanding the molecular interactions between TPO and PTU can provide insights into the inhibitory mechanisms and guide the design of more effective antithyroid medications. Objective: This study aims to elucidate the binding interactions between TPO and PTU through molecular docking, providing a detailed understanding of how PTU inhibits TPO activity. Methods: The three-dimensional structure of TPO was obtained from Prosite and modelling by swissmodel and prepared for docking. The structure of PTU was optimized, and molecular docking was performed using AutoDock. The binding affinity, binding poses, and key interactions between TPO and PTU were analyzed. Visualization of the docking results was performed using PyMOL to identify critical residues involved in PTU binding. Results: The docking analysis revealed that PTU binds effectively to the active site of TPO with a binding affinity of -5.45 kcal/mol. The interaction involves coordination with the heme group and several key residues, including His239, which coordinates the heme, and Ser314, which forms hydrogen bonds with PTU. Additionally, hydrophobic interactions with residues Phe241 and Ile399 stabilize the binding of PTU in the active site. Conclusion: The docking study highlights the significant interactions between PTU and TPO, elucidating the molecular basis of TPO inhibition by PTU. The binding affinity and key interactions identified in this study provide a foundation for the design of more potent antithyroid drugs.

Abstract

Obesity is one of the global pandemics characterized by an excessive fat buildup due to disruption of energy homeostasis in the body. As obesity is a risk factor for many other non-communicable diseases such as diabetes and coronary heart disease, it is crucial to understand the risk factors that contribute to the pathogenesis of obesity. Although obesity is mainly caused due to unhealthy lifestyles, genetic predisposition also plays a part in the pathogenesis of obesity. Individuals who carry risk alleles for genes that control energy balance in the body have a greater risk of developing obesity. Fat mass and obesity associate (FTO) is a gene strongly correlated with obesity and is widely expressed in the hypothalamus. This gene is predicted to have 89 common variations that affect obesity-related phenotypes. Among Indonesians, the three most studied single nucleotide polymorphisms (SNPs) in the first intron of the FTO gene are rs1421085, rs17817449, and rs9939609. They are strongly associated with obesity’s related traits such as weight gain, fat mass, body mass index (BMI), waist, and hip sizes. rs993609 is the most studied among diverse ethnicities in Indonesia, with AA genotype and allele A as a risk allele.

Abstract

Graves' disease is an autoimmune disorder in which the CD40-CD154 interaction plays a critical role in T-cell activation. In this study, in silico methods were employed to analyze the binding interactions of quinoline-benzoic acid derivatives (NSB, FSB, and NQB) with the CD40 receptor and to investigate the implications of specific CD40 mutations for drug efficacy. In this reseach conducted by molecular simulation approach with molecular docking Results Mutation analysis of CD40 identified alterations in key residues, such as R203C, which may impact ligand-independent activation and downstream TRAF binding, crucial for signal transduction. These findings highlight the therapeutic potential of quinoline-benzoic acid derivatives for targeting CD40 in Graves' disease, particularly in the context of receptor mutations. The integration of molecular docking, mutation analysis, and pharmacokinetic profiling provides a comprehensive framework for designing effective CD40-targeted therapies.

Abstract

This study explores the molecular landscape of cervical cancer through the identification and analysis of differentially expressed genes (DEGs) from the GSE63514 dataset. A high-confidence protein–protein interaction (PPI) network was constructed using the STRING database (v11.5) and visualized via Cytoscape, identifying 178 nodes and 1,052 edges. Using the CytoHubba plugin, the top 10 hub genes—TOP2A, MKI67, CDK1, BUB1, CCNB1, CCNA2, AURKA, CDC20, PLK1, and RFC4—were highlighted based on degree centrality. These genes are predominantly associated with cell cycle regulation, DNA replication, and mitotic division, and are potentially valuable as biomarkers or therapeutic targets for cervical cancer. Functional enrichment using DAVID and Enrichr tools revealed significant involvement of DEGs in ATP binding, spindle microtubule formation, and protein kinase activity, particularly within the chromosome centromeric region and nucleoplasm. KEGG pathway analysis identified key associations with the cell cycle, DNA replication, p53 signaling, and complement and coagulation cascades. Further heatmap analysis of treatment responders versus non-responders demonstrated distinct gene expression profiles, particularly of immune-related genes like C1QA, C3, and SERPING1, and proliferative markers such as TOP2A and MKI67. These findings underscore the dual role of immune and proliferative pathways in cervical cancer progression and suggest their utility in developing predictive biomarkers and personalized treatment strategies.

Abstract

Background: Angiogenesis is the formation of new blood vessels, is crucial for cancer growth and metastasis, including in epithelial ovarian cancer (EOC). Vascular Endothelial Growth Factor (VEGF) regulates angiogenesis, and its elevated mRNA expression is linked to poor prognosis in cancer. Genetic variations, such as the rs699947 polymorphism in the VEGF gene, can affect VEGF expression and contribute to cancer progression.Objective: The primary aim of this study is to examine the distribution of the VEGF rs699947 polymorphism and its correlation with VEGF mRNA expression levels in patients with low-grade and high-grade EOC at Dr. Cipto Mangunkusumo Hospital, Indonesia.Methods: This research is a cross-sectional analysis involving 65 normal female whole blood samples and a total of 80 ovarian cancer biopsy samples, including 15 ovarian cysts as expression calibrators, along with 36 low-grade and 29 high-grade EOC samples. The distribution of genotypes and alleles of the VEGF rs699947 polymorphism was assessed through ARMS PCR analysis, while VEGF mRNA expression was quantified using real-time qPCR.Results: Significant differences were observed in both genotype (p<0,01) and allele (p=0,000) distributions between the normal and cases group. The relative mRNA expression of VEGF was significantly elevated in both low-grade and high-grade EOC. Individuals with the homozygous VEGF rs699947 AA genotype exhibited the highest mRNA expression compared to other genotypes. In contrast, individuals carrying the CC genotype showed the lowest correlation with VEGF mRNA expression in both low-grade and high-grade EOC.Conclusion: This study shows that the A allele of VEGF rs699947 is correlated with increased VEGF mRNA expression in EOC patients, particularly in those with the AA genotype. Conversely, the C allele may offer a protective effect against EOC, as the CC genotype is linked to lower VEGF mRNA expression. Genetic screening for VEGF rs699947 could facilitate early detection and inform targeted therapeutic strategies.

Abstract

Epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein with an extracellular epidermal growth factor binding domain and an intracellular tyrosine kinase domain through signaling pathways to regulate cellular proliferation. Epidermal growth factor receptor binding to its ligand will result in autophosphorylation by intrinsic tyrosine kinase activity, thereby triggering multiple signal transduction cascades. Constant or sustained activation of these downstream target sequences is thought to result in a more aggressive tumor phenotype. Mutations in EGFR are associated with non-small cell lung cancer in passive smokers.

Abstract

Zoonotic malaria is an emerging public health issue in Indonesia, particularly in regions with significant forest cover and frequent interaction between humans and non-human primates. Information regarding the diversity and behaviour of mosquito vectors in these areas is very limited. This study aims to identify the diversity and bionomics of mosquitoes, particularly Anopheles sp., across five ecologically diverse locations in Palangkaraya, Central Kalimantan, to gain an understanding of their potential role in zoonotic malaria transmission. Cross-sectional entomological surveys were conducted during November 2022 (during the rainy season) and October 2024 (at the beginning of the rainy season). Adult mosquitoes were collected using human landing catches (HLC) from 18:00 to 06:00, and larval habitats were surveyed and characterized following the WHO protocol. A total of 1,278 mosquitoes were collected from six genera, with Anopheles letifer Sandosham dominating the Anopheles group (97%), particularly in swampy secondary forests, such as Nyaru Menteng. This species exhibited peak outdoor biting activity shortly after dusk and late at night, posing a greater risk to those outside or in unscreened homes. Larval surveys conducted at 48 sites revealed Anopheles larvae in 27% of habitats, predominantly in swamps (67% positive). Although no significant associations were found with environmental factors, natural and semi-natural water bodies appear key to sustaining vector populations. These findings highlight the ecological flexibility of An. letifer and its potential impact on zoonotic malaria transmission in forest-edge communities. Vector control strategies should include integrated methods, such as larval source management and community-based interventions, particularly in peat swamp regions where interactions between humans and non-human primates are frequent.
