We hypothesized that PVF2 may modulate age-related changes in the adult fly midgut.
Interventions that improve mammalian lifespan may provide new insights into the physiological factors that modulate aging rate and may eventually lead to treatments useful in the clinic to improve human health with age.
Studies in model organisms have identified conserved pathways that modulate aging rate and the onset and progression of multiple age-related diseases, suggesting that common pathways of aging may influence age-related diseases in humans as well.
How does PHB depletion affect mitochondrial activity to modulate aging?
While aging has historically been thought to entail cell-autonomous, even stochastic changes, recent evidence suggests that modulation of this process can be hierarchal, wherein manipulations of nutrient-sensing neurons (e.g., in the hypothalamus) produce peripheral effects that may modulate the aging process itself.
Previous work suggests that insulin signaling may modulate Drosophila aging in part through its impact on juvenile hormone titer, but no data yet address whether reduction of juvenile hormone is sufficient to control Drosophila life span.
As discussed by Savonenko and Markowska [ 37], such findings suggest that aging processes may modulate the mechanisms by which estrogen exerts physiological effects.
Combining dietary components may modulate many processes involved in ageing.
The influence of other factors that may modulate cortisol levels, such as age, pubertal stage, body mass index (BMI), adverse life events [ 37], and internalizing behavior, was also evaluated.
Collectively, these data indicate that BPA exposure decreases sex steroid hormone levels in male rodents, but strain and species, as well as other confounders (e.g., time, route of exposure, age at analysis), may modulate the sensitivity to BPA effects.
