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 …
Tubulin Post-Translational Modifications Are Altered By Changes In Actin-Myosin Contractility In Non-Muscle Cells, James Mcgee
Tubulin Post-Translational Modifications Are Altered By Changes In Actin-Myosin Contractility In Non-Muscle Cells, James Mcgee
Honors Theses
All cells regulate their contractility by the interaction of actin and myosin. In non-muscle cells, however, this interaction is regulated by rho, a GTPase, which is the upstream effector for multiple pathways. Cell contractility increases when rho is active, and prior research has shown the depolymerization of microtubules (MTs) activates rho. Microtubules play a role in many cellular functions and it is thought that either associations with MT-associated proteins and/or post-translational modifications to tubulin regulate MT functions. Numerous post-translational modifications (PTMs) to microtubules have been identified, but their roles are not well understood. A possible relationship between changes in cell …
