Abstract
Piperine, a dietary phytochemical isolated from the Piper species, has been used as a natural medicine for pain, flu, and fever in ancient China and India. Although the health benefits of piperine have been widely studied, research on its effect on aging is limited. This study aimed to determine whether piperine has the potential to mitigate aging-related changes in the fruit fly (Drosophila melanogaster), which is an excellent model organism for studies on aging. The experiments were conducted using the newly eclosed or 30-day-old D. melanogaster wild-type strain Cantonized-white. Piperine was dissolved in 99% ethanol and added to the sucrose-yeast medium at a final concentration of 10, 35, 70, or 100 μM. The study examined the effects of piperine supplementation on the lifespan of D. melanogaster and other physiological functions, such as fecundity, feeding, lipid content, and resistance to environmental stress. Log-rank tests, Shapiro-Wilk test, F-test, t-test, or Wilcoxon rank sum test were used to analyze the data. Piperine failed to change the lifespan and body weight, but increased the fecundity and decreased the feeding rate in one-week-old flies. However, when piperine was fed to 30-day-old flies, it increased the lifespan of male flies and the fecundity and feeding rate of female flies. These results indicate that piperine can improve the health of aged flies. The findings suggest that piperine has age-dependent and sex-specific anti-aging effects in fruit flies.

Smithson CH, Duncan EJ, Sait SM, Bretman A. Sensory perception of rivals has trait-dependent effects on plasticity in Drosophila melanogaster. Behav Ecol 2024; 35:arae031. [PMID: 38680228 PMCID: PMC11053361 DOI: 10.1093/beheco/arae031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 03/05/2024] [Accepted: 04/23/2024] [Indexed: 05/01/2024] Open
Abstract
The social environment has myriad effects on individuals, altering reproduction, immune function, cognition, and aging. Phenotypic plasticity enables animals to respond to heterogeneous environments such as the social environment but requires that they assess those environments accurately. It has been suggested that combinations of sensory cues allow animals to respond rapidly and accurately to changeable environments, but it is unclear whether the same sensory inputs are required in all traits that respond to a particular environmental cue. Drosophila melanogaster males, in the presence of rival males, exhibit a consistent behavioral response by extending mating duration. However, exposure to a rival also results in a reduction in their lifespan, a phenomenon interpreted as a trade-off associated with sperm competition strategies. D. melanogaster perceive their rivals by using multiple sensory cues; interfering with at least two olfactory, auditory, or tactile cues eliminates the extension of mating duration. Here, we assessed whether these same cues were implicated in the lifespan reduction. Removal of combinations of auditory and olfactory cues removed the extended mating duration response to a rival, as previously found. However, we found that these manipulations did not alter the reduction in lifespan of males exposed to rivals or induce any changes in activity patterns, grooming, or male-male aggression. Therefore, our analysis suggests that lifespan reduction is not a cost associated with the behavioral responses to sperm competition. Moreover, this highlights the trait-specific nature of the mechanisms underlying plasticity in response to the same environmental conditions.

Comput Struct Biotechnol J 2023; 21:2502-2513. [PMID: 37090432 PMCID: PMC10113763 DOI: 10.1016/j.csbj.2023.03.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 03/23/2023] [Accepted: 03/24/2023] [Indexed: 03/28/2023] Open
Abstract
Microbial communities influence host phenotypes through microbiota-derived metabolites and interactions between exogenous active substances (EASs) and the microbiota. Owing to the high dynamics of microbial community composition and difficulty in microbial functional analysis, the identification of mechanistic links between individual microbes and host phenotypes is complex. Thus, it is important to characterize variations in microbial composition across various conditions (for example, topographical locations, times, physiological and pathological conditions, and populations of different ethnicities) in microbiome studies. However, no web server is currently available to facilitate such characterization. Moreover, accurately annotating the functions of microbes and investigating the possible factors that shape microbial function are critical for discovering links between microbes and host phenotypes. Herein, an online tool, CDEMI, is introduced to discover microbial composition variations across different conditions, and five types of microbe libraries are provided to comprehensively characterize the functionality of microbes from different perspectives. These collective microbe libraries include (1) microbial functional pathways, (2) disease associations with microbes, (3) EASs associations with microbes, (4) bioactive microbial metabolites, and (5) human body habitats. In summary, CDEMI is unique in that it can reveal microbial patterns in distributions/compositions across different conditions and facilitate biological interpretations based on diverse microbe libraries. CDEMI is accessible at http://rdblab.cn/cdemi/.

Abstract
Social interactions play important roles in the modulation of behavior, physiology, and, potentially, lifespan. Although longevity has been studied extensively in different model organisms, due to the complexity of social environments, the social modulation of aging remains poorly investigated. The present study used the fruit fly, Drosophila melanogaster, as a model to study lifespan and stress resistance under different social conditions. Our experiments first showed that social isolation increased fly lifespan, suggesting a potential deleterious effect of social companions. Furthermore, we exposed flies to different aged social partners and found that living with old animals significantly reduced lifespan and stress resistance in young animals. In contrast, living with young animals increased old animal lifespan, although the effects were less robust. Overall, our results suggest that while social interaction can influence fly health, specific social partners may have more pronounced effects than others. This study provides new evidence that different social environments have significant impacts on animal physiology and longevity.

Abstract
Intestinal microbial communities participate in essential aspects of host biology, including nutrient acquisition, development, immunity, and metabolism. During host aging, dramatic shifts occur in the composition, abundance, and function of the gut microbiota. Although such changes in the microbiota are conserved across species, most studies remain descriptive and at most suggest a correlation between age-related pathology and particular microbes. Therefore, the causal role of the microbiota in host aging has remained a challenging question, in part due to the complexity of the mammalian intestinal microbiota, most of which is not cultivable or genetically amenable. Here, we summarize recent studies in the fruit fly Drosophila melanogaster that have substantially progressed our understanding at the mechanistic level of how gut microbes can modulate host aging.
