Anti-peroxynitrite treatment ameliorated vasorelaxation of resistance arteries in aging rats: involvement with NO-sGC-cGKs pathway. [PDF]

PLoS ONE, 2014
Declined vasorelaxation function in aging resistance arteries is responsible for aging-related multiple organ dysfunctions. The aim of the present study is to explore the role of peroxynitrite (ONOO-) in aging resistance arterial vasorelaxation ...

Evolutionary conservation of regulated longevity assurance mechanisms [PDF]

, 2007
Background: To what extent are the determinants of aging in animal species universal? Insulin/ insulin-like growth factor ( IGF)-1 signaling ( IIS) is an evolutionarily conserved ( public) regulator of longevity; yet it remains unclear whether the genes ...

Early cardiac aging linked to impaired stress-resistance and transcriptional control of stress response, quality control and mitochondrial pathways

, 2023
Phenotypic and transcriptomic evidence of early cardiac aging, and associated mechanisms, were investigated in young to middle-aged male mice (C57Bl/6; ages 8, 16, 32, 48 wks). Left ventricular gene expression (profiled via Illumina MouseWG-6 BeadChips),
