Abstract

Curcumin, a dietary polyphenol derived from turmeric's rhizome, exhibits a range of pharmacological activities, such as antioxidant, analgesic, antipyretic, and anti-inflammatory effects. It has been investigated for its therapeutic potential in chronic obstructive pulmonary disease (COPD) due to its ability to inhibit nuclear factor kappa B (NF-κB), modulate oxidative stress, impact cell viability, and regulate gene expression. However, most studies have been limited to in vitro conditions. To address this gap, we conducted in vivo experiments using the fruit fly Drosophila melanogaster to explore the antioxidant activities and biological significance of curcumin. Several parameters were assessed using different assays, including curcumin toxicity assay, fly survival, locomotor response to curcumin treatment (with or without cigarette smoke), trypan blue staining, larval crawling assays, and gene expression analysis. Our data revealed no significant differences in toxicity and locomotor tests across various curcumin concentrations. D. melanogaster tolerated curcumin at concentrations of 0.5 µM, 5 µM, 50 µM, and 500 µM, suggesting its safety without negatively impacting locomotor. Furthermore, curcumin at 5 µM extended the lifespan of D. melanogasterexposed to cigarette smoke, while reversing the negative effects of smoke exposure on gut cell viability and larval locomotor activity. In conclusion, curcumin administration appeared safe for D. melanogaster, with potential benefits for longevity and locomotory function. These findings support the idea that curcumin possesses in vivo antioxidant properties and may serve as a promising pharmacological agent. However, further study is needed to explore its potential applications in human health and disease management, particularly in the context of COPD.

Abstract

Aging is commonly characterized by a decline in the physiological functioning of the body organs, with one hallmark being the impairment of intestinal function, leading to increased intestinal permeability known as leaky gut. The aim of this study was to investigate the potential of curcumin to prevent the development of leaky gut in Drosophila melanogaster utilizing the smurf fly method. In this study, flies aged 3–5 days underwent a 10-day dextran sulfate sodium (DSS) treatment to induce intestinal permeability, followed by a smurf assay using brilliant blue dye and locomotor testing the next day. Flies displaying the smurf phenotype were divided into four groups: untreated control and curcumin-treated (10 µM, 50 µM, and 250 µM). After 21 days of treatment, flies were reassessed for the smurf phenotype and underwent locomotor testing. On day 23, flies were subjected to RT-qPCR analysis. By inducing increased intestinal permeability through the administration of DSS, a higher proportion of flies exhibiting the smurf phenotype and a reduced survival rate in the DSS-treated group were observed. Such phenotypes were reversed, decreased number of flies displaying the smurf phenotype and improved fly survival, upon the incorporation of curcumin in the fly food at concentrations of 10, 50, and 250 µM. Subsequent molecular analysis revealed upregulated expression of sod1, cat, and pepck genes, while no significant changes were observed in the expression of sod2, indy, and srl genes following treatment with curcumin at high concentration. Overall, our findings provide insight into the potential effect of curcumin to alleviate the phenotypical features associated with DSS-induced leaky gut, possibly via the selective regulation of aging-related genes.

Abstract

Drug repurposing is a promising approach to identify new pharmacological indications for drugs that have already been established. However, there is still a limitation in the availability of a high-throughput in vivo preclinical system that is suitable for screening and investigating new pharmacological indications. The aim of this study was to introduce the application of Drosophila larvae as an in vivo platform to screen drug candidates with anti-aging and immunomodulatory activities. To determine whether Drosophila larvae can be utilized for assessing anti-aging and immunomodulatory activities, phenotypical and molecular assays were conducted using wildtype and mutant lines of Drosophila. The utilization of mutant lines (PGRP-LBΔ and Psh[1];;ModSP[KO]) mimics the autoinflammatory and immunodeficient conditions in humans, thereby enabling a thorough investigation of the effects of various compounds. The phenotypical assay was carried out using survival and locomotor observation in Drosophila larvae and adult flies. Meanwhile, the molecular assay was conducted using the RT-qPCR method. In vivo survival analysis revealed that caffeine was relatively safe for Drosophila larvae and exhibited the ability to extend Drosophila lifespan compared to the untreated controls, suggesting its anti-aging properties. Further analysis using the RT-qPCR method demonstrated that caffeine treatment induced transcriptional changes in the Drosophila larvae, particularly in the downstream of NF-κB and JAK-STAT pathways, two distinct immune-related pathways homologue to humans. In addition, caffeine enhanced the survival of Drosophila autoinflammatory model, further implying its immunosuppressive activity. Nevertheless, this compound had minimal to no effect on the survival of Staphylococcus aureus-infected wildtype and immunodeficient Drosophila, refuting its antibacterial and immunostimulant activities. Overall, our results suggest that the anti-aging and immunosuppressive activities of caffeine observed in Drosophila larvae align with those reported in mammalian model systems, emphasizing the suitability of Drosophila larvae as a model organism in drug repurposing endeavors, particularly for the screening of newly discovered chemical entities to assess their immunomodulatory activities before proceedings to investigations in mammalian animal models.

Abstract

The escalating prevalence of diabetes represents a critical challenge to global health and quality of life. Indonesia, particularly the Sulawesi region, is home to a diverse array of endemic plants with potential as sources of novel antidiabetic compounds. However, traditional preclinical models for evaluating these candidates are limited by high costs and lengthy timelines. The aim of this study was to explore the antidiabetic potential of Cordia myxa and Syzygium malaccense extracts using Drosophila melanogaster as a novel, cost-effective and efficient in vivo model. Hyperglycemia was induced in D. melanogaster larvae through a high-sugar diet, and the plant extracts were incorporated into the larval diets at concentrations ranging from 0.3125% to 2.5%. Phenotypic parameters, including body size, body weight, crawling activity, and hemolymph glucose levels, were evaluated, and the expression of metabolism-related genes (dilp2, dilp5, and srl) was analyzed using RT-qPCR. This study found that C. myxa and S. malaccense extracts improved crawling activity and body size in hyperglycemic larvae. Notably, C. myxa extract significantly reduced hemolymph glucose levels (p<0.01), increased body weight (p<0.01), and upregulated the expression of metabolic genes such as dilp2 (p<0.001), dilp5 (p<0.001), and srl (p<0.0001). In contrast, S. malaccense extract showed less pronounced effects, highlighting the efficacy of C. myxa extract in alleviating hyperglycemia and restoring metabolic homeostasis. The study highlights that C. myxa extract demonstrated promising antidiabetic properties in the Drosophila model, underscoring the utility of this model for early-stage antidiabetic drug screening and supporting further preclinical investigation into the therapeutic potential of C. myxa for managing hyperglycemia.

Abstract

The coexistence of hyperglycemia and infectious diseases represents a critical global health challenge, particularly in resource-limited settings where it amplifies disease severity and complicates treatment approaches. Medicinal plants such as Camellia sinensis and Andrographis paniculata have gained recognition for their antioxidant, anti-inflammatory, and antimicrobial properties, making them promising candidates for addressing this double health burden. The aim of this study was to establish a preclinical model of hyperglycemia and infection (HI model) using Drosophila melanogaster and to investigate the therapeutic potential of C. sinensis and A. paniculata extracts in alleviating the burden associated with the HI condition. In this study, the HI model was established by simultaneously exposing D. melanogaster larvae to a high-concentration sucrose solution and Staphylococcus aureus for 24 hours. The larvae were then transferred to a high-sucrose diet supplemented with C. sinensis or A. paniculata extracts. Survival assays and molecular analyses were subsequently performed to evaluate the outcomes. Our findings revealed that the combination of hyperglycemia and infection significantly reduced survival rates in the Drosophila model. However, treatment with 1.25% C. sinensis and A. paniculata extracts notably improved survival, attributed to their antibacterial activity and regulation of key molecular pathways involved in immune responses, metabolic balance, and endogenous antioxidant defenses. These findings validate the utility of D. melanogaster as a model organism for investigating the double burden of HI. Furthermore, the study offers compelling evidence of the dual therapeutic potential of C. sinensis and A. paniculata in mitigating the detrimental effects of this condition. Overall, this research underscores the significant promise of plant-derived compounds in managing HI and paves the way for future studies to explore their underlying mechanisms and potential clinical applications.

Abstract

: High doses of ethanol in the body can elicit damage to organs including the brain, liver and kidneys. In addition, ethanol can trigger the formation of reactive oxygen species (ROS), where excess levels of ROS in the body can promote cell death through the apoptotic pathway. Apoptotic cells that are not phagocytosed will undergo necrosis. In the process of necrosis, cells release DAMPs, endogenous pro-inflammatory molecules and induce the core immune system in Drosophila that are homologues to humans, namely Toll, IMD (Immune Deficiency), and JAK-STAT (Janus Tyrosine Kinase-Signal Transducer and Activator of Transcription). The aim of this research is to investigate how ethanol exposure influences gene expression in the Toll, Imd, and JAK-STAT pathways. The results showed that ethanol could affect the survival rate of male and female Drosophila melanogaster w1118. Exposure to ethanol at high concentrations (85%) caused a decrease in the expression of Drs, but not the expression of the Dpt. In addition, TotA expression, but not Upd3, was amplified significantly as the ethanol concentration increased. In conclusion, Drosophila experienced a decrease in the survival rate due to ethanol exposure which might be related to the stress response and the immune system which is mediated by certain pathways.

Abstract

The aim of the research is to offer a thorough analysis of the literature on intensive reading. The Publish or Perish software and the Scopus database were two of the sophisticated research methods used to find and compile a large number of pertinent academic publications and studies. In order to guarantee that the analysis is based on the most up-to-date and reliable research available, these resources were chosen for their effectiveness in locating high-quality, peer-reviewed papers. In this study, 37 publications published between 2019 and 2023 were thoroughly examined. Mendeley software was used to methodically organize and condense references, ensuring effective administration and simple access to relevant sources. Afterward, researchers used VOSviewer software to thoroughly examine the database in an effort to find trends and patterns among the articles. To provide a more organized summary of the existing literature on this topic, the researcher also attempted to classify the papers based on important themes, approaches, and conclusions. There are three clusters found. three components in Cluster 1: reading, the intensive care unit (ICU), and the neonatal intensive care unit (NICU). Staff and families must read and understand updates, directions, and charts for both units. The terms "grade" and "intensive," which are different but closely connected, made up Cluster 2. Due to their frequent co-occurrence in the examined articles, which suggested a significant relationship in the context of the study, these two words were grouped together. The two essential terms in Cluster 3 were "effect" and "learning disability." These terms' matching in Cluster 3 suggests that the studies in question frequently examined the influence or consequences (i.e., "effect") on people with learning difficulties, underscoring the topic's applicability in the most recent literature. A better grasp of the main ideas and issues covered in the articles was made possible by the discovery and arrangement of these clusters.
