Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino Aug 2021

Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino

MSU Graduate Theses

Recent insights into the pathological role of Nucleotide P2Y2 receptor suggest P2Y2R involvement in high fat diet-induced obesity and potentiates insulin resistance. However, these recent insights do not demonstrate how P2Y2R modulates glucose homeostasis under physiological conditions. Further, it remains unknown how sex biological factors influence P2Y2R receptor signaling in the regulation of glucose homeostasis. The research objective for the present study is to elucidate the novel roles of P2Y2 in fasting blood glucose and glucose tolerance (basal insulin sensitivity) under resting conditions in males and females. We expected that under physiological …

Towards A Better Understanding Of Temporomandibular Disorder, Jessica R. Cox

MSU Graduate Theses

Results from the OPPERA study provided evidence that risk factors such as neck muscle tension, prolonged jaw opening, and female gender increase the likelihood of developing temporomandibular joint disorders (TMJD), which are prevalent, debilitating orofacial pain conditions. Peripheral and central sensitization, which mediate a lowering of the stimulus required for pain signaling, are implicated in the underlying pathology of chronic TMJD. The goal of my study was to investigate cellular changes in the expression of proteins associated with the development of central sensitization. Female Sprague-Dawley rats were injected with complete Freund’s adjuvant in the upper trapezius muscles to promote trigeminal …
