Summary Many conditions that shift cells from states of nutrient utilization and growth to cell maintenance extend lifespan. We have carried out a systematic lifespan analysis inhibit protein synthesis. find reducing the levels ribosomal proteins, ribosomal‐protein S6 kinase or translation‐initiation factors increases Caenorhabditis elegans . These perturbations, as well inhibition sensor target rapamycin (TOR), which is known increase lifespan, all thermal‐stress resistance. Thus inhibiting...

Background Aging is a fundamental biological process. Characterization of genetic and environmental factors that influence lifespan crucial step toward understanding the mechanisms aging at organism level. To capture different effects on lifespan, appropriate statistical analyses are needed. Methodology/Principal Findings We developed an online application for survival analysis (OASIS) helps conduct various novel tasks involved in analyzing data user-friendly manner. OASIS provides standard...

Abstract Ageing is marked by physical decline. Caenorhabditis elegans a valuable model for identifying genetic regulatory mechanisms of ageing and longevity. Here we report simple method to assess C. ’ maximum ability based on the worms’ movement velocity. We show velocity declines with age, correlates well longevity, accurately reports and, if measured in mid-adulthood, predictive maximal lifespan. Contrary recent findings, observe that worm mutations daf-2(e1370) insulin/IGF-1 signalling...

Airborne fine particulate matter exhibits spatiotemporal variability at multiple scales, which presents challenges to estimating exposures for health effects assessment. Here we created a model predict ambient less than 2.5 μm in aerodynamic diameter (PM2.5) across the contiguous United States be applied modeling. We developed hybrid approach combining land use regression (LUR) selected with machine learning method, and Bayesian Maximum Entropy (BME) interpolation of LUR space-time...

When unfolded proteins accumulate in the endoplasmic reticulum (ER), protein response is activated. This ER stress restores homeostasis by coordinating processes that decrease translation, degrade misfolded proteins, and increase levels of ER-resident chaperones. Ribonuclease inositol-requiring protein–1 (IRE-1), an endoribonuclease mediates unconventional splicing, its target, XBP-1 transcription factor, are key mediators response. In this study, we show Caenorhabditis elegans insulin/IGF-1...

How are the rates of aging different tissues coordinated? In Caenorhabditis elegans, decreasing insulin/IGF-1 signaling extends lifespan by activating transcription factor DAF-16/FOXO. If DAF-16 levels experimentally increased in one tissue, such as intestine, activity other rises. Here we test hypothesis that this "FOXO-to-FOXO" occurs via feedback regulation ins-7 insulin gene expression. We find regulates expression and preventing blocks FOXO-to-FOXO from intestine to tissues. Our...

Significance Reactive oxygen species (ROS) have long been thought to cause aging and considered be toxic byproducts generated during mitochondrial respiration. Surprisingly, recent studies show that modestly increased ROS levels lengthen lifespan, at least in the roundworm Caenorhabditis elegans . It was unclear how of potentially are regulated promote longevity. Here we demonstrate activate two proteins, AMP-activated kinase (AMPK) hypoxia-inducible factor 1 (HIF-1), longevity by increasing...

Glucose-rich diets shorten the life spans of various organisms. However, metabolic processes involved in this phenomenon remain unknown. Here, we show that sterol regulatory element-binding protein (SREBP) and mediator-15 (MDT-15) prevent life-shortening effects a glucose-rich diet by regulating fat-converting Caenorhabditis elegans . Up-regulation SREBP/MDT-15 transcription factor complex was necessary sufficient for alleviating effect diet. Glucose feeding induced key enzymes convert...

The penetration of PVs into the power grid is increasing day by day, as they are more economical and environment-friendly. However, due to intrinsic intermittency in solar radiation other meteorological factors, generated from uncertain unstable. Therefore, accurate forecasting generation considered one fundamental challenges system.

Rhabdoid tumors (RT) are aggressive pediatric malignancies with poor prognosis. INI1/hSNF5 is a component of the chromatin remodeling SWI/SNF complex and tumor suppressor deleted in RT. Previous microarray studies indicated that reintroduction into RT cells leads to repression high degree mitotic genes including Aurora Kinase A (Aurora A, STK6). Here, we found INI1/SNF5 represses transcription cell-type-specific manner. INI1-mediated was observed normal but not non-RT cell lines. Chromatin...

In Caenorhabditis elegans and Drosophila melanogaster, removing the germline precursor cells increases lifespan. worms, possibly also in flies, this lifespan extension requires presence of somatic reproductive tissues. How gonad signals other tissues to increase is not known. The triggered by loss germ known require sterol hormone signaling, as reducing activity nuclear receptor DAF-12, or genes required for synthesis DAF-12 ligand dafachronic acid, prevents from extending addition FOXO...
