Analysis of young worms fed live lactic acid bacteria (LAB) Lactobacillus rhamnosus CNCM I-3690 or CNCM I-4317 for 3 days. L. rhamnosus CNCM I-3690 protects against oxidative stress and increases lifespan in worms. Results provide insight into probiotic LAB-induced oxidative stress protection.

(Submitter supplied) Numerous studies have shown that resistance to oxidative stress is crucial to stay healthy and to reduce the adverse effects of aging. Accordingly, nutritional interventions using antioxidant food-grade compounds or food products are currently an interesting option to help improve health and quality of life in the elderly. Live lactic acid bacteria (LAB) administered in food, such as probiotics, may be good antioxidant candidates. more...

(Submitter supplied) In the present study, we investigated the effect of CBM 588 on lifespan and multiple-stress resistance using Caenorhabditis elegans as a model animal. When adult C. elegans were fed a standard diet of Escherichia coli OP50 or CBM 588, the lifespan of the animals fed CBM 588 was significantly longer than that of animals fed OP50. Moreover, the worms fed CBM 588 were more resistant to certain stressors, including infections with pathogenic bacteria, UV irradiation, and the metal stressor Cu2+. more...

(Submitter supplied) One of the most important issues in the study of aging is to discover compounds with longevity-promoting activity and to unravel their underlying mechanisms. Queen honey bees are continuously fed royal jelly (RJ), and they live more than 10 times longer than hive workers, derived from the same diploid genome, which are fed it only for a short period of time during their larval stages. Therefore, RJ is likely to contain longevity-promoting agents for queens. more...

(Submitter supplied) We analyzed RNA-seq data from C. elegans on six bacterial diets, 3 E. coli diets (OP50, HT115, HB101) found in the laboratory setting and 3 found in C. elegans natural environment (Methylobacterium, Xanthomonas, Sphingomonas). We compared gene expression between L4 worms on the OP50 diet to the other 5 bacterial diets. We found that diet influences many gene expression changes, leading to genes being both up regulated and down regulated in a diet-dependent manner.

(Submitter supplied) Analysis of wildtype (N2) C. elegans fed different diets: E. coli OP50, E. coli HT115 and Comamonas DA1877 Dietary composition has major effects on physiology. Here we show that developmental rate, reproduction and lifespan are altered in C. elegans fed Comamonas DA1877 relative to those fed a standard E. coli OP50 diet. We identify a set of genes that change in expression in response to this diet, and use the promoter of one of these (acdh-1) as a dietary sensor. more...
