Longevity and age-related pathology of mice deficient in pregnancy-associated plasma protein-A.
The pregnancy-associated plasma protein-A knockout (PAPP-A KO) mouse is a model of reduced local insulin-like growth factor (IGF)-I activity with normal circulating IGF-I levels. In this study, PAPP-A KO mice had significantly increased mean (27%), median (27%), and maximum (35%) life span compared with wild-type (WT) littermates. End-of-life pathology indicated that the incidence of neoplastic...
متن کاملPregnancy-associated plasma protein A in pregnancy-related gynaecologic emergency.
Serum concentrations of pregnancy-associated plasma protein A (PAPP-A) were measured in patients with pregnancy-related gynaecologic emergencies including ectopic pregnancy (n = 124) and intrauterine abortion (n = 40). The results were compared with those in normal pregnancy (n = 136) and non-pregnant women (n = 460). In ectopic pregnancy and intrauterine abortion, the PAPP-A levels were lower ...
متن کاملComparison of pregnancy-associated plasma protein-A, troponin and creatine kinase-MB levels in acute coronary syndrome
Background: Early diagnosis and proper treatment of patient with acute coronary syndrome (ACS) and ischemic heart disease are important in determining prognosis, preventing adverse effects, and may even save lives. In this study, the level of pregnancy-associated plasma protein-A (PAPP-A) in ACS patients was compared with the control group, in addition to cardiac Troponin (cTn) and creatine kin...
متن کاملMetabolic consequences of pregnancy-associated plasma protein-A deficiency in mice: exploring possible relationship to the longevity phenotype.
Mice born with the deletion of the gene for pregnancy-associated plasma protein-A (PAPP-A), a model of reduced local IGF activity, live approximately 30% longer than their wild-type (WT) littermates. In this study, we investigated metabolic consequences of PAPP-A gene deletion and possible relationship to lifespan extension. Specifically, we determined whether 18-month-old PAPP-A knockout (KO) ...
متن کاملAge-Related Retinopathy in NRF2-Deficient Mice
BACKGROUND Cumulative oxidative damage is implicated in the pathogenesis of age-related macular degeneration (AMD). Nuclear factor erythroid 2-related factor 2 (NRF2) is a transcription factor that plays key roles in retinal antioxidant and detoxification responses. The purposes of this study were to determine whether NRF2-deficient mice would develop AMD-like retinal pathology with aging and t...
