Understanding The Pathogenesis Of Renal Medullary Carcinoma, Melinda Soeung
Understanding The Pathogenesis Of Renal Medullary Carcinoma, Melinda Soeung
Dissertations & Theses (Open Access)
Renal medullary carcinoma (RMC) is a lethal cancer that predominantly affects young individuals with sickle cell trait (SCT). It is not currently understood why RMC only affects certain individuals with SCT. We found that patients with RMC more frequently participated in high-intensity exercise than matched controls. Using mouse models of SCT, we demonstrated the significant increase of renal hypoxia in the right kidney following high- but not moderate-intensity exercise. We also demonstrated in cell culture studies that SMARCB1 is ubiquitinated for proteasome-mediated degradation in hypoxia, and the re-expression of SMARCB1 leads to compromised proliferation in renal cells specifically in the …
Glucose Metabolism Of Breast Cancer Sub-Clones That Preferentially Metastasize To The Lungs And Bone, Anna G. Skubiz
Glucose Metabolism Of Breast Cancer Sub-Clones That Preferentially Metastasize To The Lungs And Bone, Anna G. Skubiz
Honors Theses
Malignant breast cancers exhibit preferential metastasis to bone and lung (1). While changes in gene expression in lung-specific (LM) and bone-specific metastasis (BoM) lines derived from the MDA-MB-231 breast cancer line have been identified, few metabolic genes are differentially expressed; thus it is unknown if tissue-specific metabolic reprogramming occurs. Two hallmarks of cancer cells are an altered metabolic phenotype characterized by enhanced conversion of glucose to lactate in spite of adequate oxygen availability for complete mitochondrial oxidation of this substrate (referred to as aerobic glycolysis or the Warburg effect) and a greater dependence on glutamine. These changes in primary tumor …
Pyruvate Kinase Isoform M2 Influences Autophagy And Related Processes In Hepatocellular Carcinoma Cells, Matthew Lin
Pyruvate Kinase Isoform M2 Influences Autophagy And Related Processes In Hepatocellular Carcinoma Cells, Matthew Lin
University Scholar Projects
Hepatocellular carcinoma (HCC) is the most common form of liver cancer that affects ~14 million people in the world. Like all cancers, HCC is a disease that arises from unstinted cellular growth initiated by genetic alterations, metabolic changes, and dysregulation in key cellular pathways. Of interest is the relationship between metabolism and cell proliferation/degradation for therapeutic targeting. Pyruvate kinase M2 is a dimeric, glycolytically inactive isoform of the final enzyme involved in glycolysis, that is often upregulated in cancerous tissue. It is thought that the enzymatic function of PKM2 outside of glycolysis contributes to the biosynthesis of anabolic intermediates used …
The Role Of T-Box Proteins In Vertebrate Germ Layer Formation And Patterning, Sushma Teegala
The Role Of T-Box Proteins In Vertebrate Germ Layer Formation And Patterning, Sushma Teegala
Dissertations, Theses, and Capstone Projects
All of the tissues in triploblastic organisms, with the exception of the germ cells, arise from the three germ layers, ectoderm, mesoderm and the endoderm. The identification of the genes that underlie the differentiation of these layers is crucial to our understanding of development. T-box family proteins are DNA-binding transcriptional regulators that play important roles during germ layer formation in the early vertebrate embryo. Well-characterized members of this family, including the transcriptional activators Brachyury and VegT, are essential for the proper formation of mesoderm and endoderm, respectively. To date, T-box proteins have not been shown to play a role in …
Chemotherapy: The Physiological Cost Of A Cure, Megan Ellis
Chemotherapy: The Physiological Cost Of A Cure, Megan Ellis
A with Honors Projects
This project focuses on the common long term side effects of cancer treatments, apart from cure. In addition to physiological function changes, it focuses on the chemical composition of chemotherapy drugs.
