It is well documented that menopause and the related decline in circulatory steroid hormones estrogen and progesterone are associated with memory alterations. Rodent models of surgical menopause can be used to study these effects, including ovariectomy (Ovx), or the surgical removal of the ovaries. This thesis aimed to characterize the effects of surgical menopause on spatial working and reference memory in rats and examine profiles of uterine gene expression alterations that may serve as indications of mechanisms underlying this association. Eighteen female rats were randomly assigned to one of two surgical treatment groups, either Ovx (the surgical menopause group) or sham (the control group). All subjects underwent testing on the water version of the radial arm maze (WRAM) which allows for the assessment of reference memory errors and two types of working memory errors. After behavioral testing, rat uterine tissues were dissected and RNA sequenced. The results showed that Ovx impaired spatial reference memory performance during a maze learning phase, with Ovx rats making reference memory failures earlier in the day, even before working memory load increased, as compared to control rats. There were no surgical menopause effects on spatial working memory, which may be due to the low working memory load and the young age of the rats. Post-hoc analyses showed that reference memory performance was correlated with nerve growth factor (NGF) and acetylcholinesterase (AChE) gene expression in uterine tissues. These findings add to the literature on the impact of estrogen and female cyclicity on memory and cognition. The results suggest that Ovx impairment of the ability to learn long-term spatial memory information relates to uterine gene expression underlying cellular functioning and that NGF and AChE genes are involved in pathways that give way to underlying cellular functioning that impacts cognition. Future studies should continue to evaluate the effects of menopause on memory function and the effectiveness of hormone therapy.
