Treatment Strategies In Acute Myelogenous Leukemia : Investigating Hsp90 And P53 As Targets, Jennifer M. Napper
Treatment Strategies In Acute Myelogenous Leukemia : Investigating Hsp90 And P53 As Targets, Jennifer M. Napper

Acute myelogenous leukemia (AML) is the deadliest of the lymphatic and bone marrow cancers. Patients diagnosed with AML have a five year survival rate of 23.4%. AML is characterized by an accumulation of undifferentiated and functionless myeloid precursors in the bone marrow and blood. Heat shock protein 90 (Hsp90) inhibitors, such as 17-AAG, an analog of geldanamycin (GM), are currently undergoing phase I, and II and III clinical trials for various cancers with mixed results. I found distinct responses to 17-AAG treatment among the AML cell lines tested. I also discovered two mutant TP53 alleles in Kasumi-3 cells, an AML …
Age- And Sex-Associated Changes In Mrna Expression Of Neurodegenerative Disorder-Related Molecules In The Hippocampus And Cerebellum Of Rat Brain, Srinivasarao Thulluri
Age- And Sex-Associated Changes In Mrna Expression Of Neurodegenerative Disorder-Related Molecules In The Hippocampus And Cerebellum Of Rat Brain, Srinivasarao Thulluri

Age-associated oxidative stress is involved in neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases, and sex-associated differences may also affect the risk for these neurodegenerative diseases. We compared the effects of aging and sex on the mRNA expression of five molecules that are closely related to oxidative stress, along with Alzheimer’s and Parkinson’s diseases in the hippocampus of both male and female Fischer 344xBrown Norway (F344BN) rats. The reverse transcription polymerase chain reaction was used to determine the mRNA expression level of superoxide dismutase 2 (SOD2), heme oxygenase 1 (HO1), amyloid precursor protein (APP), -site APP-cleaving enzyme 1 (BACE1), and …

Acute myelogenous leukemia (AML) and its precursors are the result of the dysregulation of hematopoiesis. Hematopoiesis proceeds in a stepwise manner, beginning with hematopoietic stem cells, continuing to develop into various stages of progenitor cells, and finally becoming fully functional blood cells. As this process goes awry, immature, functionless cells of the myeloid lineage proliferate out of control. Discerning how myeloid progenitor frequency is regulated allows for a better understanding of how the process may lose control. Hematopoiesis has been shown to depend on genetic and environmental factors. In this work, I have added to this knowledge base by providing …
The Expression And Function Of Hypoxia Inducible Factor-1Α In Human Melanoma, Sandeep S. Joshi
The Expression And Function Of Hypoxia Inducible Factor-1Α In Human Melanoma, Sandeep S. Joshi
Theses, Dissertations and Capstones
Hypoxia inducible factor-1α (HIF-1α) protein, a key regulator of oxygen homeostasis, is stabilized under hypoxia and degraded under normal oxygen tension. Here, the human melanoma cells were found to express an elevated amount of HIF-1α mRNA and protein relative to normal human melanocytes under normoxic conditions. The amount of HIF-1α expressed is roughly correlated with the stage of melanoma from which the cell line was established. In addition, a splice variant mRNA of HIF-1α785 is expressed at higher levels than full-length HIF-1α mRNA in the more aggressive melanoma cells. This splice variant lacks part of the oxygen regulation domain. Ectopic …
