The Role Of Pfkfb3 In Ampk-Activated Glut4 Translocation, Katherine Renee Bosch
The Role Of Pfkfb3 In Ampk-Activated Glut4 Translocation, Katherine Renee Bosch
Senior Honors Theses
Type 2 diabetes is a chronic, potentially deadly disease that impacts millions of Americans’ lives. Type 2 diabetes is characterized by increased blood glucose levels caused by insulin resistance. The normal insulin signaling pathway leads to glucose uptake by GLUT4 through activation of the IRS-1-PI3K-Akt pathway, as well as the insulin-independent pathway that utilizes AMPK. Additionally, PFKFB3 may play a role in insulin signaling and glucose uptake. PFKFB3 is an enzyme that plays an important role in activating PFK-1, which is a rate-limiting enzyme in glycolysis. PFKFB3 is frequently studied for its role in cancer due to its role in …
Genetic Analysis Of Hereditary Gingival Fibromatosis Associated Sos1 Missense Variants Of Uncertain Significance In Caenorhabditis Elegans, Himani Patel
Theses
Hereditary gingival fibromatosis (HGF) is a disease that can present as benign overgrowth of gingival tissue in the mouth. The overgrowth can enclose the entire mouth and teeth in severe cases or present itself in a concentrated area. Researchers have identified that mutations in the SOS1 gene can be responsible for HGF. This disease can impair basic functions related to the mouth. Eating, smiling, speaking can all be affected. Additionally, excess inflammation can cause periodontal disease because of the difficulty in maintaining proper oral health. Periodontal disease can lead to severe bone loss which can lead to complete loss of …

Unraveling Sorafenib Resistance In Hepatocellular Carcinoma: Exploring Key Facets, Dennis Kwabiah, Kyle Doxtater, Yamile Abuchard, Sophia Leslie, Ricardo Pequeno Bracho, Shaibir Hussain, Manish K. Tripathi
Research Symposium
Hepatocellular carcinoma (HCC) stands as the prevalent form of primary liver cancer worldwide, diagnosing over half a million new cases annually. Surgical interventions like hepatectomy and liver transplantation offer a potential cure for early-stage HCC. However, the prognosis for advanced stages remains grim due to drug resistance, particularly with high refractoriness rates. Sorafenib, a tyrosine kinase inhibitor, is an approved treatment for advanced HCC. Despite its use, the overall survival extension for these patients remains limited due to the drug's ineffectiveness, and the mechanism behind advanced HCC's resistance to sorafenib remains elusive. TCGA analysis of HCC patient cohorts reveals elevated …

Cancer metastasis is one of the deadliest aspects of the disease, with about 90% of all cancer-related deaths due to its development at different sites within the body. Colorectal cancer (CRC) is the second leading cause of cancer mortality in the United States, with 40-50% of all patients developing metastasis at some point during their fight with the disease. With the approval of Regorafenib for treating metastatic colorectal cancer, steps have been taken to combat metastasis in colorectal cancer. A vital aspect of the development of metastasis is the development of resistance to first-line chemotherapy. Regorafenib is an oral small-molecule …
Hif Expression In Clear-Cell Renal Cell Carcinoma (Ccrcc) Tumors Of Adults With And Without Obstructive Sleep Apnea (Osa), Olivia Heppell, Carlos Guerra Londono, Nilesh Gupta
Hif Expression In Clear-Cell Renal Cell Carcinoma (Ccrcc) Tumors Of Adults With And Without Obstructive Sleep Apnea (Osa), Olivia Heppell, Carlos Guerra Londono, Nilesh Gupta
Medical Student Research Symposium
Introduction: Upregulation of hypoxia-inducible factors (HIF) is an important pathological feature shared by clear cell renal cell carcinoma (ccRCC) and obstructive sleep apnea (OSA). However, it is unclear whether OSA alters the pathogenesis of ccRCC via HIF expression.
Methods: A retrospective cohort of adults undergoing nephrectomy for ccRCC was identified electronically (IRB#16040-1). The diagnosis of OSA was established with preoperative STOP-BANG scores or polysomnography. A consecutive sample of 20 individuals with and 20 without OSA was selected. Clinical characteristics and pathology results were reviewed. Resected tumor sections were immunohistochemically stained for HIF-1& HIF-2 at antibody dilutions of 1:150. Intensity and …
Ksp1 Is An Autophagic Receptor Protein For The Snx4-Assisted Autophagy Of Ssn2/Med13, Sara E Hanley, Stephen D Willis, Steven J Doyle, Randy Strich, Katrina F Cooper
Ksp1 Is An Autophagic Receptor Protein For The Snx4-Assisted Autophagy Of Ssn2/Med13, Sara E Hanley, Stephen D Willis, Steven J Doyle, Randy Strich, Katrina F Cooper
Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship
Ksp1 is a casein II-like kinase whose activity prevents aberrant macroautophagy/autophagy induction in nutrient-rich conditions in yeast. Here, we describe a kinase-independent role of Ksp1 as a novel autophagic receptor protein for Ssn2/Med13, a known cargo of Snx4-assisted autophagy of transcription factors. In this pathway, a subset of conserved transcriptional regulators, Ssn2/Med13, Rim15, and Msn2, are selectively targeted for vacuolar proteolysis following nitrogen starvation, assisted by the sorting nexin heterodimer Snx4-Atg20. Here we show that phagophores also engulf Ksp1 alongside its cargo for vacuolar proteolysis. Ksp1 directly associates with Atg8 following nitrogen starvation at the interface of an Atg8-family interacting …

Mucopolysaccharidoses (MPSs) are a group of inborn errors of the metabolism caused by a deficiency in the lysosomal enzymes required to break down molecules called glycosaminoglycans (GAGs). These GAGs accumulate over time in various tissues and disrupt multiple biological systems, including catabolism of other substances, autophagy, and mitochondrial function. These pathological changes ultimately increase oxidative stress and activate innate immunity and inflammation. We have described the pathophysiology of MPS and activated inflammation in this paper, starting with accumulating the primary storage materials, GAGs. At the initial stage of GAG accumulation, affected tissues/cells are reversibly affected but progress irreversibly to: (1) …

Low-cost, highly-sensitivity, and minimally invasive tests for the detection and monitoring of life-threatening diseases and disorders can reduce the worldwide disease burden. Despite a number of interdisciplinary research efforts, there are still challenges remaining to be addressed, so clinically significant amounts of relevant biomarkers in body fluids can be detected with low assay cost, high sensitivity, and speed at point-of-care settings. Although the conventional proteomic technologies have shown promise, their ability to detect all levels of disease progression from early to advanced stages is limited to a limited number of diseases. One potential avenue for early diagnosis is microRNA (miRNA). …
