A naturally occurring bovine model with excess follicular fluid androstenedione (High A4), reduced fertility, and polycystic ovary syndrome (PCOS)-like characteristics has been identified. We hypothesized High A4 granulosa cells (GCs) would exhibit altered cell proliferation and/or steroidogenesis. Microarrays of Control and High A4 GCs combined with Ingenuity Pathway Analysis indicated that High A4 GCs had cell cycle inhibition and increased expression of microRNAs that inhibit cell cycle genes. Granulosa cell culture confirmed that A4 treatment decreased GC proliferation, increased anti-Müllerian hormone, and increased mRNA for CTNNBIP1. Increased CTNNBIP1 prevents CTNNB1 from interacting with members of the WNT signaling pathway thereby …

Efficacy Of Anti-Mullerian Hormone In The Diagnosis Of Polycystic Ovarian Syndrome, Cassidy Prewitt

Capstone Showcase

Introduction: Polycystic ovarian syndrome (PCOS) is a complex condition that presents with a wide variety of symptoms. The PCOS diagnosis standard is the Rotterdam criteria, which includes hyperandrogenism, oligo-anovulation, and polycystic ovarian morphology (PCOM). Transvaginal ultrasounds have traditionally been used to evaluate PCOM, however, they are highly dependent on technician skill. This paper will evaluate research regarding the use of anti-Mullerian (AMH) in PCOS diagnosis as an alternative to transvaginal ultrasound.

Methods: A literature search was conducted using PubMed and Academic Search Ultimate in January 2020. A total of eight articles were selected based on relevance to the research topic …
