Abstract

Aging is associated with changes in circulating levels of various molecules, some of which remain undefined. We find that concentrations of circulating taurine decline with aging in mice, monkeys, and humans. A reversal of this decline through taurine supplementation increased the health span (the period of healthy living) and life span in mice and health span in monkeys. Mechanistically, taurine reduced cellular senescence, protected against telomerase deficiency, suppressed mitochondrial dysfunction, decreased DNA damage, and attenuated inflammaging. In humans, lower taurine concentrations correlated with several age-related diseases and taurine concentrations increased after acute endurance exercise. Thus, taurine deficiency may be a driver of aging because its reversal increases health span in worms, rodents, and primates and life span in worms and rodents. Clinical trials in humans seem warranted to test whether taurine deficiency might drive aging in humans.

Abstract

We present a global atlas of 4,728 metagenomic samples from mass-transit systems in 60 cities over 3 years, representing the first systematic, worldwide catalog of the urban microbial ecosystem. This atlas provides an annotated, geospatial profile of microbial strains, functional characteristics, antimicrobial resistance (AMR) markers, and genetic elements, including 10,928 viruses, 1,302 bacteria, 2 archaea, and 838,532 CRISPR arrays not found in reference databases. We identified 4,246 known species of urban microorganisms and a consistent set of 31 species found in 97% of samples that were distinct from human commensal organisms. Profiles of AMR genes varied widely in type and density across cities. Cities showed distinct microbial taxonomic signatures that were driven by climate and geographic differences. These results constitute a high-resolution global metagenomic atlas that enables discovery of organisms and genes, highlights potential public health and forensic applications, and provides a culture-independent view of AMR burden in cities.

Abstract

Although disinfection is key to infection control, the colonization patterns and resistomes of hospital-environment microbes remain underexplored. We report the first extensive genomic characterization of microbiomes, pathogens and antibiotic resistance cassettes in a tertiary-care hospital, from repeated sampling (up to 1.5 years apart) of 179 sites associated with 45 beds. Deep shotgun metagenomics unveiled distinct ecological niches of microbes and antibiotic resistance genes characterized by biofilm-forming and human-microbiome-influenced environments with corresponding patterns of spatiotemporal divergence. Quasi-metagenomics with nanopore sequencing provided thousands of high-contiguity genomes, phage and plasmid sequences (>60% novel), enabling characterization of resistome and mobilome diversity and dynamic architectures in hospital environments. Phylogenetics identified multidrug-resistant strains as being widely distributed and stably colonizing across sites. Comparisons with clinical isolates indicated that such microbes can persist in hospitals for extended periods (>8 years), to opportunistically infect patients. These findings highlight the importance of characterizing antibiotic resistance reservoirs in hospitals and establish the feasibility of systematic surveys to target resources for preventing infections. Spatiotemporal characterization of microbial diversity and antibiotic resistance in a tertiary-care hospital reveals broad distribution and persistence of antibiotic-resistant organisms that could cause opportunistic infections in a healthcare setting.

Abstract

Caenorhabditis elegans (C. elegans) is a well-established model organism used across a range of basic and biomedical research. Within the nematode research community, there is a need for an affordable and effective way to maintain large, age-matched populations of C. elegans. Here, we present a methodology for mechanically sorting and cleaning C. elegans. Our aim is to provide a cost-effective, efficient, fast, and simple process to obtain animals of uniform sizes and life stages for their use in experiments. This tool, the Caenorhabditis Sieve, uses a custom-built lid system that threads onto common conical lab tubes and sorts C. elegans based on body size. We also demonstrate that the Caenorhabditis Sieve effectively transfers animals from one culture plate to another allowing for a rapid sorting, synchronizing, and cleaning without impacting markers of health, including motility and stress-inducible gene reporters. This accessible and innovative tool is a fast, efficient, and non-stressful option for maintaining C. elegans populations.

26. Characterization Of The Antiaging Effects Of Apple Phytochemicals Using The C. Elegans Model

Author

Vayndorf, Elena

Abstract

Aging is a major risk factor for many chronic diseases, including cancer and cardiovascular disease. The resulting need to understand and alleviate age-related decline has led to pharmacological manipulation of age-related degeneration in many species, including the nematode Caenorhabditis elegans, one of the simplest whole-animal models. However, few such studies have examined the anti-aging effects of natural compounds found in fruits and vegetables. Apples are the number one source of phenolics in U.S. diets. Apple phytochemicals have been shown to have a variety of salubrious effects, including high antioxidant and antiproliferative activity and the modulation of several molecular targets. We treated C. elegans with apple extracts, and found that lifespan increased significantly by up to 39%. Healthspan was also significantly improved as measured by two biomarkers, lipofuscin and motility. Additionally, animals pre-treated with apple extracts were more resistant to stresses such as heat, UV radiation, paraquat-induced oxidative stress, and pathogenic infection, suggesting that cellular defense system functions were also improved. To find the mechanisms behind these improvements, we screened several mutants that affect lifespan via different pathways. Prolonged lifespan does not appear to be mediated by calorie restriction, insulin signaling, sirtuins, or germ line signaling. Instead, the effects are at least partly due to reduced oxidative stress, as indicated by the increased lifespan of the mev-1 mutant. We also observed an increased induction of the promoter activity of small heat shock protein hsp16.2, and a reduction of induction of the promoter activity of superoxide dismutase and glutathione-Stransferase, two enzymes that attenuate excessive reactive oxidative species. This is consistent with the idea that apple extracts may protect against deleterious oxidative damage normally mitigated by sod-3 and gst-4, leading to a decreased need for this part of the endogenous antioxidant system. We propose that in C. elegans apple phytochemicals act through a synergistic mechanism that involves attenuation of ROS damage, in particular superoxide anions, and generalized detoxification of oxidation byproducts. In addition, increased induction of the promoter of hsp16.2 likely contributes to a general improvement of cellular detoxification and stress response, and explains improved survival under conditions of stress.
