Project description:Aging is a physiological process characterized by a progressive decline of biological functions and an increase in destructive processes in cells and organs. Physical activity and exercise positively affects the expression of skeletal muscle markers involved in longevity pathways. Recently, a new mechanism, autophagy, was introduced to the adaptations induced by acute and chronic exercise as responsible of positive metabolic modification and health-longevity promotion. However, the molecular mechanisms regulating autophagy in response to physical activity and exercise are sparsely described. We investigated the long-term adaptations resulting from lifelong recreational football training on the expression of skeletal muscle markers involved in autophagy signaling. We demonstrated that lifelong football training increased the expression of messengers: RAD23A, HSPB6, RAB1B, TRAP1, SIRT2 and HSBPB1, involved in the auto-lysosomal and proteasome-mediated protein degradation machinery; of RPL1, RPL4, RPL36, MRLP37, involved in cellular growth and differentiation processes; of the Bcl-2, HSP70, HSP90, PSMD13 and of the ATG5-ATG12 protein complex, involved in proteasome promotion and autophagy processes in muscle samples from lifelong trained subjects compared to age-matched untrained controls. In conclusion, our results indicated that lifelong football training positively influence exercise-induced autophagy processes and protein quality control in skeletal muscle, thus promoting healthy aging. The aim of the present research was to investigate, through a differential transcriptomic approach, the effects of lifelong recreational football training on the expression of key markers involved in the autophagy response for the maintenance of protein quality control, related to healthy longevity promotion, in skeletal muscle from VPG compared to elderly untrained control subjects.

Project description:The molecular level the different muscular signature from Veteran soccer Players (VPG) vs age-matched active healthy subjects (control group, CG) was explored by using a proteomic approach. V. lateralis muscle biopsies were investigated in order to highlight the molecular mechanisms that characterize a successful aging through a lifelong football training

Project description:Caloric restriction and intermittent fasting prolong the lifespan and healthspan of model organisms and improve human health 1. The natural polyamine spermidine has been linked to autophagy regulation, geroprotection and reduced incidence of cardiovascular and neurodegenerative diseases across species borders 2. Here, we report that spermidine levels increase upon acute fasting in yeast, flies, mice and healthy humans. Genetic or pharmacological blockade of endogenous spermidine synthesis reduced fasting-induced autophagy in yeast, worms and human cells. Furthermore, perturbing the polyamine pathway in vivo abrogated the lifespan-extending, cardioprotective and antiarthritic effects of intermittent fasting. Mechanistically, spermidine mediated these effects via hypusination of the autophagy regulator eIF5A. In sum, the polyamine-hypusination axis thus emerges as a bona fide and phylogenetically conserved metabolic control hub for longevity and autophagy induction.

Project description:Probiotics play important role in maintaining the health and extend longevity in their host. Previous studies reported several live probiotic bacteria in enhancing longevity and improving diverse feature of the host’s health. In this study, we reported a new potential heat- killed probiotic bacterium Levilactobacillus brevis strain MRKAK9 improved longevity and different features of healthy aging, including age-associated physical activity, improved resistance to biotic and abiotic stress in C. elegans. The mechanistic investigations showed that heat-killed strain MRKAK9 promoted longevity and healthy aging by downregulating insulin-signaling pathway resulting in improved proteostasis, autophagy and preserving lysosomal functionality in C. elegans. Heat-killed strain MRKAK9-mediated downregulation of insulin signaling pathway was regulated by the miRNA mir-243, suggesting that mir-243 partially involved in enhancing longevity of C. elegans. Additionally, the structural component exopolysaccharide of the strain heat-killed MRKAK9 also downregulated insulin- signaling mechanisms, increased the expression of genes involved in proteostatsis, autophagy as well as improved expression of mir-243. This study indicates that heat-killed strain MRKAK9 improves longevity and healthy aging, suggesting its candidature as a novel postbiotic.

Project description:Bees were trained to visit food sources at different times of day. By collecting bees just before the training times, we were able to analyze the genes that are associated with the time of day, the time of training, the activity state, or genes associated with unique spatiotemporal memories

Project description:The identification of genes that confer either extension of life span or accelerate age-related decline was a step forward in our understanding the mechanisms of senescence and revealed that aging process is partially controlled by genetics and transcriptional programs. Here we identified that the unknown DNA sequence c16orf70 encodes for a protein, named Mytho, that controls life span. Mytho is conserved from worms to humans and is upregulated in aged mice and elderly people. Deletion of the ortholog Mytho gene in C. elegans dramatically shortened life-span and decreased animal survival upon exposure to oxidative stress. Mechanistically, MYTHO is required for autophagy because it acts as scaffold to recruit and assemble the conjugation system at the phagophore assembly site (PAS). We conclude that Mytho is a transcriptionally regulated initiator of autophagy that is central in promoting stress resistance to ensure organism longevity.

Project description:High blood glucose level is one of the main characteristics of diabetes mellitus (DM). It is speculated that longevity families may have certain advantages in blood glucose regulation. But till now, limited information on these items is reported. In this study, a TMT- based comparative quantitative proteomics analysis was used to reveal the changes of plasma proteomics profiles between longevity subjects and non-longevity area participants in order to identify plasma proteins associated with glucose metabolism in longevity population and to explore the characteristics of blood glucose regulation in longevity population

Project description:Combining resistance and endurance exercises in a training regime (concurrent training) can impair improvements in muscle hypertrophy, strength, and power compared to resistance training alone. Here we aimed to characterize skeletal muscle transcriptomic changes following chronic concurrent training to determine whether contraction-induced gene expression may reveal molecular underpinnings explaining impaired adaptations. Eighteen young, healthy male participants underwent 12 weeks of resistance, endurance, or concurrent training. Maximal strength, aerobic capacity, and anaerobic power were assessed. Transcriptomics were performed on skeletal muscle biopsies obtained pre and post-intervention. Improvements to maximal anaerobic power are impaired with concurrent and endurance training. Gene expression related to plasma membrane structures was enriched while gene expression related to regulation of mRNA processing and protein degradation was suppressed with concurrent training. Considerable overlap of gene expression related to extracellular matrix remodeling was observed between concurrent and endurance training. Our results provide the first comprehensive comparison of unique and overlapping gene sets enriched following chronic resistance, endurance, and concurrent training, and reveals pathways that may have implications in relation to impaired adaptations when undertaking concurrent training.
