Combinatorial Modulation Of Multiple Signaling Pathways To Gain Therapeutic Response In Breast And Prostate Cell Carcinomas, William Tressel Hawkins Ii
Combinatorial Modulation Of Multiple Signaling Pathways To Gain Therapeutic Response In Breast And Prostate Cell Carcinomas, William Tressel Hawkins Ii
Theses and Dissertations
Our laboratory is primarily interested in novel pharmacological intervention of cell proliferation and survival pathways expressed in various types of cancer. These cyto-protective pathways can be activated in response to growth factor stimulation, toxic insult and radiation. In our studies, we utilized novel drug combinations with and without radiation to enhance breast & prostate tumor cell death both in vitro and in vivo. Previous studies from our group have shown that UCN-01 and MEK1/2 inhibitors interact to cause tumor cell death in transformed cell lines in vitro. We extended this observation to an in vivo animal model system using the …

Assessing Epidermal Growth Factor Expression In The Rodent Hippocampus Following Traumatic Brain Injury, Janice Mabutas Daus
Theses and Dissertations
Hippocampal neurons are vulnerable to injury, as indicated by the prevalence of learning and memory deficits following traumatic brain injury. Research indicates that proliferation of neural precursor cells increases following brain injury, which implies that there is an endogenous response in the hippocampus to replenish neurons and restore cognitive function. Studies show that mitogenic growth factors may drive this proliferative response; one of which is epidermal growth factor. Because adults and the elderly manifest the most enduring deficits following TBI, it is critical to investigate how EGF expression following injury may relate to injury-induced cell proliferation and the degree of …
Characterization Of The Tcof1 Gene Using A Neuroblastoma Cell Line And A Mouse Model, Lin Li
Characterization Of The Tcof1 Gene Using A Neuroblastoma Cell Line And A Mouse Model, Lin Li
Theses and Dissertations
Treacher Collins syndrome (TCS) is an autosomal dominant craniofacial development disorder and is caused by mutations in the TCOF1 gene. The TCOFl protein treacle is a nucleolar protein and may function in ribosome biogenesis.Previously, we identified downstream candidate genes using microarray analysis after manipulating Tcofl levels in a murine neuroblastoma (NB) cell line. The list of genes includes cell cycle genes as well as the transcription factors Cnbp and Tbx2, which are known to affect the cell cycle through the c-myc and p19-Mdm2-p53-p21 pathways respectively. To further characterize the cellular effects of Tcofl, stably transfected NB cell lines with overexpression …
