Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease with dismal prognosis. The only curative option for patients is surgery, but over 80% of patients are not surgical candidates. Unfortunately, PDAC is resistant to the three remaining options. PDAC is characterized by a profoundly hypoxic and immunosuppressive stroma, which contributes to its therapeutic recalcitrance. Alpha-smooth muscle actin+ (αSMA+) cancer-associated fibroblasts (CAFs) are the most abundant stromal component, as well as mediators of stromal deposition. The hypoxia-inducible factors (HIF1 and HIF2) coordinate responses to hypoxia, yet, despite their known association to poor patient outcomes, their functions within the PDAC tumor microenvironment (TME) …
The Effect Of Hypoxia On Brain Cell Proliferation In Weakly Electric Fish, Petrocephalus Degeni, Kaitlin Klovdahl
The Effect Of Hypoxia On Brain Cell Proliferation In Weakly Electric Fish, Petrocephalus Degeni, Kaitlin Klovdahl
Senior Theses and Projects
Oxygen levels tend to remain at a steady state concentration in the Earth’s atmosphere, yet in some bodies of water, they can fluctuate and decrease drastically. Many organisms that inhabit the swamps, lakes, streams, and parts of the ocean where this occurs have evolved adaptations to manage this environmental uncertainty and continue normal oxygen consumption. The Lwamunda swamp in Uganda is chronically hypoxic, yet it is home to many species, including the electric fish Petrocephalus degeni. P. degeni are unusual by nature of their immense brain, and the Lwamunda swamp appears ill-suited for maintaining this large, metabolically active organ. To …
The Effects Of Methamphetamine Exposure On Cardiovascular Development In Combination With Hypoxia In Danio Rerio, Sarah Donaldson
The Effects Of Methamphetamine Exposure On Cardiovascular Development In Combination With Hypoxia In Danio Rerio, Sarah Donaldson
Williams Honors College, Honors Research Projects
The purpose of this study was to determine the effects of methamphetamine combined with hypoxia on the development and function of the cardiovascular system in Danio rerio embryos. It was hypothesized that the combined effect of the drug and decreased oxygen concentration would result in decreased cardiac parameters due to underdevelopment of the ventricle and vessels resulting from cardiomyopathy and lack of blood flow to tissues. It was found that methamphetamine exposure correlated to an increase in stroke volume, caudal artery and vein diameters and RBC velocities alone, while having a multiplicative effect of increasing arterial RBC velocity when combined …
