The Estradiol-Induced Transcriptome Of The Female Mouse Anteroventral Periventricular Nucleus: More Than Just A Kiss, Leah K. Aggison

Doctoral Dissertations

Estradiol (E2) is critical in the reproductive mechanisms of mammals. In female rodents E2 acts through the neurons of the anteroventral periventricular nucleus (AVPV) to exert neuroendocrine control over ovulation, via synaptic activation of the gonadotropin releasing hormone (GnRH) neurons. The neurocircuitry of the AVPV is complex, receiving input from the suprachiasmatic nucleus and ventral premammillary nucleus and the as well as projecting to organum vasculosum of lamina terminalis and the arcuate. This suggests a broader role for the AVPV as a center of multisignal-integration in regards to ovulation. I used full genome expression microarrays to assess the ...


Increased Body Weight In Adulthood Following A Peripubertal Stressor And Proposed Mechanism For Effects Of Increased Adiposity On Estrogen-Dependent Behaviors, Christina F. Gagliardi Nov 2014

Increased Body Weight In Adulthood Following A Peripubertal Stressor And Proposed Mechanism For Effects Of Increased Adiposity On Estrogen-Dependent Behaviors, Christina F. Gagliardi

Masters Theses

Exposure to certain stressors during a sensitive period around puberty can lead to enduring effects on an animal’s response to estradiol. In estradiol-influenced behaviors, such as sexual receptivity, hippocampal-dependent learning and memory, depression-like behavior, and anxiety-like behaviors, exposure to a peripubertal stressor such as shipping stress or an injection of lipopolysaccharide (LPS) can eliminate or even reverse the normal response to estradiol. In addition to regulating these behaviors, estradiol play a role in the regulation of body weight. While some of the previous studies touched on short-term effects on body weight, no systemic long-term study of the effects of ...
