Interaction Between Atm Kinase And P53 In Determining Glioma Radiosensitivity, Syed F. Ahmad
Interaction Between Atm Kinase And P53 In Determining Glioma Radiosensitivity, Syed F. Ahmad
Theses and Dissertations
Glioblastoma multiforme (GBM) is the most common primary brain tumor. Studies have shown that targeting the DNA damage response can sensitize cancer cells to DNA damaging agents. Ataxia telangiectasia mutated (ATM) is involved in signaling DNA double strand breaks. Our group has previously shown that ATM inhibitors (ATMi) sensitize GBM cells and tumors to ionizing radiation. This effect is greater when the tumor suppressor p53 is mutated.
The goals of this work include validation of a new ATM inhibitor, AZ32, and elucidation of how ATMi and p53 status interact to promote cell death after radiation. We propose that ATMi and …
Nitric Oxide Synthase Activity And Its Modulation In The Treatment Of Colorectal Cancer, Asim Alam
Nitric Oxide Synthase Activity And Its Modulation In The Treatment Of Colorectal Cancer, Asim Alam
Theses and Dissertations
The American Cancer Society estimates more than 141,000 new cases of and about 50,000 deaths from colorectal cancer every year. Treatment options include surgery, radiation therapy and targeted therapies such as anti-angiogenics. However, no therapies address the key driving factor of colorectal cancer: inflammation. It is well known that chronic inflammatory conditions such as Crohn’s Disease, ulcerative colitis, diabetes, obesity and cigarette smoking all elevate the risk of developing colorectal cancer. One of the hallmarks of chronic inflammation is the elevated levels of reactive oxygen/nitrogen species (ROS/RNS). A primary source of these ROS/RNS is uncoupled Nitric Oxide Synthase (NOS). Under …
Genomic Aberrations At The 3q And 14q Loci: Investigation Of Key Players In Ovarian And Renal Cancer Biology, Punashi Dutta
Genomic Aberrations At The 3q And 14q Loci: Investigation Of Key Players In Ovarian And Renal Cancer Biology, Punashi Dutta
USF Tampa Graduate Theses and Dissertations
Genomic aberrations are primary contributors to the pathophysiology of cancer [11]. Dysregulated expression of genes located within these aberrations are important predictors of chemoresistance, disease prognosis, and patient outcome [12]. This dissertation is focused on understanding the regulation and/or functions of specific genes located at dysregulated genomic regions such as 3q26 and 14q32 in the biology of ovarian and renal cancer, respectively.
Serous epithelial ovarian cancer (EOC) manifest amplification at the 3q26.2 locus [2], an observation consistent with the cancer genome atlas (TCGA) [13]. The most amplified gene in this region is EVI1 which has been extensively studied in hematological …
