A steroid hormone that extends the lifespan of Caenorhabditis elegans.
Removing the germline of Caenorhabditis elegans extends lifespan. This lifespan extension requires the nuclear receptor DAF-12 and the cytochrome P450 DAF-9, suggesting that a lipophilic hormone is involved. Here we show that C. elegans contains several hormonal steroids that are also present in humans, including pregnenolone (3beta-hydroxy-pregn-5-en-20-one; PREG) and other pregnane and andros...
متن کاملthe Caenorhabditis elegans lifespan machine
nAture methods | ADVANCE ONLINE PUBLICATION | the measurement of lifespan pervades aging research. Because lifespan results from complex interactions between genetic, environmental and stochastic factors, it varies widely even among isogenic individuals. the actions of molecular mechanisms on lifespan are therefore visible only through their statistical effects on populations. indeed, survival ...
متن کاملBlueberry polyphenols increase lifespan and thermotolerance in Caenorhabditis elegans
The beneficial effects of polyphenol compounds in fruits and vegetables are mainly extrapolated from in vitro studies or short-term dietary supplementation studies. Due to cost and duration, relatively little is known about whether dietary polyphenols are beneficial in whole animals, particularly with respect to aging. To address this question, we examined the effects of blueberry polyphenols o...
متن کاملPharmacological classes that extend lifespan of Caenorhabditis elegans
Recent progress in the field of aging has resulted in ever increasing numbers of compounds that extend lifespan in Caenorhabditis elegans. Lifespan extending compounds include metabolites and synthetic compounds, as well as natural products. For many of these compounds, mammalian pharmacology is known, and for some the actual targets have been experimentally identified. In this review, we explo...
متن کاملLifespan extension by conditions that inhibit translation in Caenorhabditis elegans.
Many conditions that shift cells from states of nutrient utilization and growth to states of cell maintenance extend lifespan. We have carried out a systematic lifespan analysis of conditions that inhibit protein synthesis. We find that reducing the levels of ribosomal proteins, ribosomal-protein S6 kinase or translation-initiation factors increases the lifespan of Caenorhabditis elegans. These...
