Lipid Raft Disruption Alters Human Follicle Stimulating Hormone Receptor Signaling, Rachel Judith Godek Jun 2022

Lipid Raft Disruption Alters Human Follicle Stimulating Hormone Receptor Signaling, Rachel Judith Godek

Honors Theses

Over 6.7 million people struggle with infertility each year. Studying signaling by reproductive hormones in fertility can allow us to gain a better understanding of the signaling pathways that must function correctly for proper fertility. Some infertility is due to incorrect human follicle stimulating hormone receptor (hFSHR) function. When follicle stimulating hormone (FSH) binds to hFSHR this begins a signaling cascade where the end product is the maturation of sperm by Sertoli cells in men, and egg development and production of estrogen through stimulation of granulosa cells in women. It has been determined that hFSHR is localized to microdomains of …


Investigating The Role Of The Cholesterol Recognition/Interaction Amino-Acid Consensus Sequence In Follicle Stimulating Hormone Receptor Function And Structure, Tatyana Lynn Jun 2022

Investigating The Role Of The Cholesterol Recognition/Interaction Amino-Acid Consensus Sequence In Follicle Stimulating Hormone Receptor Function And Structure, Tatyana Lynn

Honors Theses

Human infertility is a complex disorder that can often be attributed to a dysfunction of the endocrine system. Follicle-stimulating hormone (FSH) is one of many hormones that participate in a complex process in both women and men to regulate normal reproduction. The dysfunction of this hormone and its receptor are some of the many causes of infertility. FSH is secreted by the anterior pituitary and, in women, initiates a cascade of biological events that enable ovulation. FSH carries out its function by binding and activating specific receptors. The FSH receptor (FSHR) is a G protein-coupled receptor (GPCR) that is located …


Analysis Of Differential Gene Expression Patterns During Spiral Intestine Development In Leucoraja Erinacea, Kelsey Cox Jun 2021

Analysis Of Differential Gene Expression Patterns During Spiral Intestine Development In Leucoraja Erinacea, Kelsey Cox

Honors Theses

The vertebrate gut is a specialized structure responsible for the intake and digestion of food, absorption of nutrients, and expulsion of waste products. The organs of the digestive tract have been conserved over time, but modifications to the size and shape of individual structures exist within the different vertebrate lineages. The skate’s spiral intestine has evolved to maximize nutrient absorption within a compact structure to create space in the body cavity for the organs needed for buoyancy. Studying the unique intestinal morphology of Leucoraja erinacea, or the little skate, provides an opportunity to understand the role of differential gene expression …


Investigating Human Follicle Stimulating Hormone Receptor And Its Partners Using The Apex Assay, Alexandra Temple Jun 2020

Investigating Human Follicle Stimulating Hormone Receptor And Its Partners Using The Apex Assay, Alexandra Temple

Honors Theses

Many men and women deal with fertility whether it’s needing infertility treatments or contraceptives. The follicle stimulating hormone (FSH) and follicle stimulating hormone receptor (FSHR) play important roles in reproduction and fertility in both males and females. Fertility issues can arise when interactions between FSH and FSHR aren’t functioning properly and FSHR signaling is disrupted. FSHR is a G-protein coupled receptor (GPCR) found on the cell surface of granulosa cells in women and Sertoli cells in men. Activated FSHR initiates a cascade of downstream signaling events that result in different biological effects such as ovarian follicular development and estrogen production …


Elucidating The Role Of Apoptosis During Cyclical Body Regeneration In Botryllus Schlosseri, Meredith Adamo Jun 2013

Elucidating The Role Of Apoptosis During Cyclical Body Regeneration In Botryllus Schlosseri, Meredith Adamo

Honors Theses

Apoptosis is the principal form of programmed cell death by which multicellular animals rid themselves of old cells in order to allow new cells to grow. The colonial ascidian Botryllus schlosseri is a model system for homeostatic cell death and regeneration. During its unique, weekly budding cycle known as blastogenesis, new buds are produced asexually and eventually replace the old adult zooid generation through resorption via circulating phagocytes. Using polyester wax-embedded tissue sections, we have shown that TUNEL-positive (terminal deoxynucleotidyl transferase nick end-labeling), apoptotic cells are observed within circulating phagocytes in all stages of the colony’s death phase (takeover), including …
