2 | Downregulation of exo-3 | 6239 | Schlotterer et al., 2010 | 20346071 | Whole body | Age | — | — | — | — |
39 | AMP/ATP increases | 6239 | Apfeld et al., 2004 | 15574588 | whole body | Age | 4 day | 18 day | Hemaphrodite | AMP/ATP ratio in living animals increases from <0.1 at day 4 of adulthood to 0.8 at day 18 (an age near the maximum lifespan of the population). Linear regression indicates a strong correlation between AMP/ATP ratio and life expectancy. |
60 | Protein aggregation | 6239 | — | 22103665 | whole body | age | 1 day | 11 day | hermaphrodites | protein aggreation accumulate in aged animals. Hundrets of protein are enriched in an SDS-insoluble fraction in aged nematode adn alre largely absent from similiar protein fraction in young nematodes. Genes encoding proteins that become insoluble with age are enriched for modifiers of lifespan [22103665]. |
61 | Loss of protein homeostasis | 6239 | — | 22103665 | whole body | — | 1 day | 11 day | hermaphrodites | Loss in protein homeostasis during aging may lead to impaird protein solubility and cellular dysfunction [22103665]. |
62 | Fertility declines | 6239 | — | 20041217 | whole body | age | — | — | females | Fertility and reproduction sharply decline in early/mide-adulthood, folloed by a long post-reproductuve period, followed by a long-post-reproductive period [6,7 in 20041217]. |
63 | Fertility declines | 9606 | 20041217 | — | whole body | age | — | — | females | Female fertility declines in the mid-adulthood and reproduction ceases, followed by a long post-reproductive period [Refs in 20041217]. |
57 | White matter integrity decreases | 9606 | Samanez-Larkin et al., 2012 | 22496578 | white matter | age | 21 year | 85 year | males/females | Older age is associated with decreased reward learning and decreased white matter integrity in specific pathways running form the thalamus to the medial prefrontal cortex and from the meial prefrontal cortex to the ventral stratium |
59 | Deteriorarition of circadian rhytms | 10090 | Farajnia, et al 2012 | — | Suprachiasmatic Nucleus | age | 2 month | 30 month | — | Aged mice have disrupted sleep hevaiour and weakened brain network activity in the SCN. Aged SCN neurons lack day-night rhythms in some membrane properties. There is an age-related reductions of certain potassium currents that are import to the neuronâs rhythmic firing. Behavioral and sleep-wake rhythms exhibit a strong fragmentation, starting at the age of 700 d. Aged mice are deficient in membrane properties and GABAergic postsynaptic current amplitude. Aging mice selectively loss circadian modulation of fast-delayed-rectifer and A-type K+ currents. In aged mice at the tissue level, the phase synchrony of SCN neurons was grossly disturbed, with some subpopulations peaking in anti-phase and a reduction in amplitude of the overall multiunit activity rhythm. |
69 | Loss of subcutaneous adipose skin layer | 10090 | — | 19013273 | skin | age | 5 | 165 | — | With increasing age the subcutaneous adipose layer becomes thinner (5-12 weeks vs. 123-165 weeks) and this loss is associated with increased risk of skin injuries and infections [19013273]. |
51 | DHEA increases | 9606 | Willcox et al., 2007 | 17986602 | serum | diet | Okinawa | — | — | Okinawa aged 65-plus have relatively high DHEA levels. |
52 | DHEA decreases | 9606 | Hinson and Raven, 1999 | 10495400 | serum | age | 25 year | 85 year | males/females | DHEAS (Dehydroepiandrosterone sulphate) is the most abundant circulating steroid secreted by adrenal glands. Duo to its position int the steroid cascade DHEA act like kind of âthe mother steroidâ (Regelson et al., 1994). DHEA reaches its highest levels at age 20-24. Its serum concentration declines with increasing age after 25 years and diminishes about 95% by 85 years. DHEA deficiency syndrome is a new term for old age [10495400]. |
53 | DHEA increases | 9606 | Hinson and Raven, 1999 | 10495400 | serum | age | 10 year | 20 year | males/females | DHEA reaches its highest levels at age 20-24 [10495400]. |
54 | DHEA decreases | 9544 | Lane et al., 1997 | 9215277 | serum | Age | 5 year | 26 year | males/females | Males and female rhesus monkeys exhibit a steady, age-related decline in serum DHEAS. The proportional age-related loss of DHEAS in rhesus moneys is over twice the rate of decline observed in humans [9215277]. |
