Inhibition Of Pim And Axl Kinases As Potential Treatments For A Variety Of Hematological Malignancies And Solid Tumors, Kent James Carpenter
Inhibition Of Pim And Axl Kinases As Potential Treatments For A Variety Of Hematological Malignancies And Solid Tumors, Kent James Carpenter
Theses and Dissertations
This thesis is divided into three chapters. In each case, the goal is to achieve inhibition of a growth kinase (PIM or AXL) and subsequent arrest of cell growth and induction of apoptosis (in vitro cell culture models) or decrease in tumor volume (in vivo xenograft studies). Chapter one and chapter two discuss inhibition of proviral integration site for Moloneymurine leukemia virus (PIM) kinases. The three PIM kinases, PIM-1, PIM-2, and PIM-3, are a subfamily of serine/threonine kinases that are known to be involved in signaling pathways as downstream effectors of signal transducer and activator of transcription-5 (STAT5) signaling and …

The impact of Ad.mda-7 on the survival of renal cell carcinoma lines (RCC), primary renal epithelial cells, glioblastoma multiforme lines (GBM), and primary rodent astrocytes is unknown. The present studies examine whether the GST fusion protein, GST-MDA-7, and the adenovirus, Ad.mda-7, altered the growth and survival of the A498 and UOK121N RCC lines or radiosensitized GBM, respectively. Due to previous findings that the RCC lines, but not primary renal epithelial cells, were resistant to type 5 adenoviral infection, we used purified GST-MDA-7 protein to show that GST-MDA-7, but not GST, caused a dose-dependent reduction in A498 and UOK121N proliferation but …
Role Of Mdm2 In Cell Growth Regulation, Rebecca Anne Frum
Role Of Mdm2 In Cell Growth Regulation, Rebecca Anne Frum
Theses and Dissertations
MDM2 has been shown to induce G0-Gl/S phase arrest. To determine the cell cycle step targeted by MDM2, flow cytometry was employed to detect induction of events during the G1-S phase transition in MDM2-arrested cells. MDM2 overexpression does not prevent expression of cyclin D, cyclin D-CDK mediated phosphorylation of Rb or cyclin E in normal, immortal or tumor-derived cells. However, MDM2 down-regulates cyclin A expression specifically in normal cells, which is associated with G1 arrest. The domain of MDM2 capable of this function is located within its N-terminal 58-109 amino acids. To down-regulate cyclin A, MDM2 requires a functional pl6/Brg …
