Lipid Raft Disruption Alters Human Follicle Stimulating Hormone Receptor Signaling, Rachel Judith Godek
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
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 …
Molecular Characterization Of Galectin From Amblyomma Americanum In Context Of Α-Gal Syndrome, Sumar Beauti
Molecular Characterization Of Galectin From Amblyomma Americanum In Context Of Α-Gal Syndrome, Sumar Beauti
Honors Theses
The lone star tick Amblyomma americanum is a vector of various disease-causing pathogens and tick-borne alpha-gal syndrome (AGS) with rapidly expanding populations in the south- and northeast regions of the United States. This study aimed to molecularly characterize galectin and determine its involvement in galactose-α-1,3-galactose (α-gal) synthesis, transport, reproductive fitness, and microbial homeostasis in this tick. The lone star tick galectin possesses two conserved carbohydrate recognition domains and shares homology with other Ixodid tick galectins. Time and tissue-dependent expression data shows that galectin is constantly expressed in salivary glands, midgut, and ovary tissues. An RNA interference approach was used to …
The Impact Of Age/Rage Signaling On Oxidative Stress Under Diabetic Conditions In Cardiac Fibroblasts, Christopher Dorroh
The Impact Of Age/Rage Signaling On Oxidative Stress Under Diabetic Conditions In Cardiac Fibroblasts, Christopher Dorroh
Honors Theses
Diabetes is a major health concern in the United States, with 1.5 million new cases diagnosed each year. Patients who suffer from diabetes have an increased risk of developing heart failure, a form of cardiovascular disease. Heart failure has been shown to result from increased left ventricular stiffness, which in turn is caused by increased remodeling of the extracellular matrix (ECM). This increase in ECM remodeling is a result of AGE/RAGE signaling, which occurs at a heightened level in the cardiac fibroblast cells of diabetics. Studies have shown that diabetics have elevated levels of AGEs (Advanced Glycation End-Products), which bind …
Investigating Phosphorylation Patterns And Their Effect On The Activity Of Transcription Factor Taabf1 In Imbibing Cereal Grains, Grace Uwase
Honors Theses
The wheat transcription factor TaABF1 plays an important role in hormone-mediated regulation of seed dormancy and germination of cereal grains. Evidence shows that TaABF1 activity is regulated by phosphorylation, and previous work in our lab showed that when serine residues in its conserved regions; S36, S37, S113, S115 were altered to phosphomimetic aspartate, the 4xD TaABF1 mutant had increased activity as a transcription factor. However, when only S113 was altered, TaABF1’s activity was greatly reduced. The work presented here explored whether the S36D/S37D/S115D mutant would have stronger activity than the 4xD mutant. Using the particle bombardment technique to introduce the …

Alteration In 5ht1a Receptor Activity From A Prenatal Exposure To Dexamethasone In A Stressed And Non-Stressed Adult Male Rat, Darshan S. Shah
Alteration In 5ht1a Receptor Activity From A Prenatal Exposure To Dexamethasone In A Stressed And Non-Stressed Adult Male Rat, Darshan S. Shah
Honors Theses
Synthetic glucocorticoids (GC) are used as a clinical therapeutic to stimulate lung development in fetuses that present the risk of preterm delivery. Previous studies have shown that a prenatal exposure to Dexamethasone (DEX) causes a disturbance in normal GC mediation of neuritic outgrowth, cell signaling, and serotonergic systems. Our hypothesis is that a prenatal exposure to DEX during the third trimester of pregnancy alters 5HT1A receptor function. Pregnant dams were injected daily with 150μg/ml/kg of DEX from gestation day 14 through 19. Control dams were treated with and equal volume of saline. Swim stress followed by elevated plus maze testing …
