STUDY QUESTION Are brain-derived neurotrophic factor (BDNF) and its receptors, NTRK2, NGFR and SORT1, regulated by ovarian steroids in the uterus? SUMMARY ANSWER BDNF and its low affinity receptor, nerve growth factor receptor (NGFR), are regulated by estradiol in the uterus. WHAT IS KNOWN ALREADY Recent studies have revealed a central role for neurotrophins in placental development, endome...
Current evidence indicates that the mammalian target of rapamycin inhibitor rapamycin both increases longevity and, seemingly contradictorily, impairs glucose homeostasis. Most studies exploring the dimensions of this paradox have been based on rapamycin treatment in mice for up to 20 wk. We sought to better understand the metabolic effects of oral rapamycin over a substantially longer period o...
BACKGROUND Ankylosing spondylitis (AS) is a male-predominant disease, and radiographic evidence of damage is also more severe in males. Estrogen modulates immune-related processes such as T cell differentiation and cytokine production. This study aimed to evaluate the effect of estrogen on the disease activity of spondyloarthritis (SpA). METHODS The effects of estrogen on the development of a...
Objectives: Ovariectomy of young rodents is the most frequently used animal model of the menopause. However, the assumption that ovariectomy, causing a rapid loss of ovarian hormones is a general model of menopause in not well supported. Several animal models have been developed with the aim of mitigating the human conditions of the menopause. Among these, the ovotoxin 4-vinylcyclohexene diepox...
Sex differences in skeletal muscle regeneration are controversial; comparisons of regenerative events between sexes have not been rigorously defined in severe injury models. We comprehensively quantified inflammation and muscle regeneration between sexes and manipulated sex-specific hormones to determine effects on regeneration. Cardiotoxin injury was induced in intact, castrated and ovariectom...
