A long post-reproductive lifespan is a shared trait among genetically distinct killer whale populations [PDF]

, 2021
The extended female post-reproductive lifespan found in humans and some toothed whales remains an evolutionary puzzle. Theory predicts demographic patterns resulting in increased female relatedness with age (kinship dynamics) can select for a prolonged ...

Reproductive Suicide: Similar Mechanisms of Aging in C. elegans and Pacific Salmon

Frontiers in Cell and Developmental Biology, 2021
In some species of salmon, reproductive maturity triggers the development of massive pathology resulting from reproductive effort, leading to rapid post-reproductive death.

The somatic reproductive tissues of C. elegans promote longevity through steroid hormone signaling. [PDF]

PLoS Biology, 2010
In Caenorhabditis elegans and Drosophila melanogaster, removing the germline precursor cells increases lifespan. In worms, and possibly also in flies, this lifespan extension requires the presence of somatic reproductive tissues.

Genetic and pharmacological factors that influence reproductive aging in nematodes. [PDF]

PLoS Genetics, 2007
Age-related degenerative changes in the reproductive system are an important aspect of aging, because reproductive success is the major determinant of evolutionary fitness.

Semelparous Death as one Element of Iteroparous Aging Gone Large

Frontiers in Genetics, 2022
The aging process in semelparous and iteroparous species is different, but how different? Death in semelparous organisms (e.g., Pacific salmon) results from suicidal reproductive effort (reproductive death).

Age at Menarche and Menopause, Reproductive Lifespan, and Risk of Cardiovascular Events Among Chinese Postmenopausal Women: Results From a Large National Representative Cohort Study

Frontiers in Cardiovascular Medicine, 2022
BackgroundAt present, the association between age at menarche and menopause, reproductive lifespan, and cardiovascular disease (CVD) risk among Chinese postmenopausal women is not clear, and some related researches are contradictory.MethodsA total of 6 ...

Methylation of ribosomal RNA by NSUN5 is a conserved mechanism modulating organismal lifespan [PDF]

, 2015
Several pathways modulating longevity and stress resistance converge on translation by targeting ribosomal proteins or initiation factors, but whether this involves modifications of ribosomal RNA is unclear.

The gustatory system influences "Drosophila" lifespan [PDF]

, 2011
The lifespan of an organism is affected by the complex interplay between genetic and environmental factors. In C. elegans, this interaction between genes and environment is mediated by the sensory system.

Reproductive Lifespan and Motor Progression of Parkinson's Disease. [PDF]

J Clin Med, 2022
Objectives: Estrogen not only plays a key role in the decreased risk of Parkinson’s disease (PD) but also influences its severity. We aimed to explore the effect of the reproductive lifespan on the motor progression of PD female patients in a large
