Frost450, A Novel Microtubule Targeting Agent: Resistance And Cross-Resistance In An Ovarian Cancer Cell Line, Jonathan Chancellor Fox
Frost450, A Novel Microtubule Targeting Agent: Resistance And Cross-Resistance In An Ovarian Cancer Cell Line, Jonathan Chancellor Fox
Undergraduate Honors Theses
Drug resistance remains problematic for chemotherapy treatments. As primary treatment strategies tend to lose potency against cancer, there is a need for treatment options that overcome drug resistance mechanisms. FROST450, a novel microtubule destabilizing agent, has proven anticancer effects that overcome taxane and multidrug resistance. However, to better understand the clinical potential of FROST450, in this study we examine the mechanisms and implications of acquired FROST450 resistance in an A2780 ovarian cancer cell line. Results indicate FROST450 resistance is associated with increased mitochondrial respiration and with changes in gene sequence or expression level of proteins associated with microtubules, and that …

Tumors of similar size and shape can exhibit different responses to the same treatment. Targeted therapy aims to better treat these tumors by classifying them according to genotypic traits. A better understanding of how tumor traits such as non-stem cells influence tumor growth could improve targeted therapy. We hypothesize that the production of non-stem cells may aid tumor growth in avascular tumors (tumors lacking blood vessels).

The mechanistic target of rapamycin (mTOR) pathway is involved in placental growth and function during pregnancy. The mTOR pathway responds to nutrient availability and growth factors regulating protein transcription and cell growth. mTOR disruptions are associated with the development of obstetric complications which may result in adverse health outcomes for the mother and/or fetus. The purpose of this study is to identify the differing placental expression of various mTOR-associated proteins during normal gestation (Control), gestational diabetes mellitus (GDM), intrauterine growth restriction (IUGR) and preeclampsia (PE). Immunohistochemistry was used to stain human placenta for activated proteins (phospho; p)AKT, (p)ERK, (p)mTOR, (p)p70 …

The Pyruvate kinase isozymes M2 (PKM2) protein is a metabolic enzyme that regulates the final step of glycolysis. This enzyme is present in highly proliferating cells such as those present in embryonic tissues, cancer and in the placental trophoblast. We recently studied PKM2 protein in the human placenta at term. Our results demonstrated upregulated placental PKM2 during preeclampsia (PE) where trophoblast invasion is decreased and hypoxia is present. Our objective was to determine the cytosolic and nuclear PKM2 expression pattern and determine PKM2 regulation of trophoblast cell invasion. Trophoblast cells were cultured in normoxic and hypoxic conditions and real time …
