The Role Of Exosomes In Prostate Field Cancerization, Julie Nguyen
The Role Of Exosomes In Prostate Field Cancerization, Julie Nguyen
Student Scholar Symposium Abstracts and Posters
Field cancerization is formally defined as the presence of molecular alterations in structurally normal tissues adjacent to tumors. Currently, the etiology of prostate field cancerization is still unknown. We hypothesize that exosomes (vesicles excreted by cells that may contain protein, lipids, or RNA) are released by tumors and are endocytosed by adjacent normal cells converting them into abnormal cells, thereby aiding cancer progression. The following biomarkers have been associated with field cancerization: MIC-1, PDGF-A, FASN, and EGR-1, while markers for exosomes are CD-9, CD-63, and PSMA. To test this hypothesis, exosomes were isolated from human prostate cancer cell models LNCaP …
Thermodynamics And Kinetics Of The Three-Way Junction Of Phi29 Motor Prna And Its Assembly Into Nanoparticles For Therapeutic Delivery To Prostate Cancer, Daniel W. Binzel
Thermodynamics And Kinetics Of The Three-Way Junction Of Phi29 Motor Prna And Its Assembly Into Nanoparticles For Therapeutic Delivery To Prostate Cancer, Daniel W. Binzel
Theses and Dissertations--Pharmacy
The emerging field of RNA nanotechnology necessitates creation of functional RNA nanoparticles, but has been limited by particle instability. Previously, it was found the three-way junction (3WJ) of the Phi29 DNA packaging motor pRNA was found to be ultra-stable and assemble in solution without the presence of metal ions. The three-way junction is composed of three short oligo RNA strands and proven to be thermodynamically stable. Here the assembly mechanism, thermodynamic and enzymatic stabilities, and kinetics are examined in order to understand the stability behind this unique motif. Thermodynamic and kinetics studies found that the pRNA 3WJ formed out of …
Dysregulation Of Micrornas In Blood As Biomarkers For Diagnosing Prostate Cancer, Rhonda W. Daniel
Dysregulation Of Micrornas In Blood As Biomarkers For Diagnosing Prostate Cancer, Rhonda W. Daniel
Theses and Dissertations
Prostate cancer is the most common noncutaneous cancer among men, yet current diagnostic methods are insufficient and more reliable diagnostic markers need to be developed. The answer that can bridge this gap and enable more efficient diagnoses may lie in microRNAs. These small, single stranded RNA molecules impact protein expression at the translational level and regulate important cellular pathways. Dysregulation of these small RNA molecules can have tumorigenic effects on cells and lead to many types of cancers.
Currently the Prostate-Stimulating Antigen (PSA) is used as a diagnostic marker for prostate cancer. However, many factors can elevate PSA levels such …
Angiomotin Is A Novel Cadherin-11 Interacting Protein That Mediates Migration In Prostate Cancer Cells, Angelica Ortiz
Angiomotin Is A Novel Cadherin-11 Interacting Protein That Mediates Migration In Prostate Cancer Cells, Angelica Ortiz
Dissertations & Theses (Open Access)
Prostate cancer (PCa), the second leading cause of cancer-related deaths among men in the United States, has the proclivity to metastasize to bone resulting in sclerotic lesions. These cancer induced bone growths cause bone pain and fractures. Therefore, understanding the molecular mechanisms contributing to PCa bone metastasis is required in order to find better prognostic tools and suitable targets for metastasis treatment and/ or prevention. Previous work in our laboratory showed increased expression of cadherin-11 (Cad11), a mesenchymal cadherin, during PCa progression. Furthermore, Cad11 expression endows PCa cells with increased migratory potential and metastasis to bone. Deletion of the Cad11 …
Identification And Characterization Of Fkbp52-Specific Inhibitors For The Treatment Of Prostate Cancer, Johanny Tonos De Leon
Identification And Characterization Of Fkbp52-Specific Inhibitors For The Treatment Of Prostate Cancer, Johanny Tonos De Leon
Open Access Theses & Dissertations
Steroid hormone receptors require the ordered assembly of various chaperone and cochaperone proteins in order to reach a functional state. The final stage in the receptor maturation process requires the formation of a mutimeric complex consisting of Hsp90 dimer, p23, and one of several large immunophilins. Studies conducted previously demonstrated that the large immunophilin FKBP52 acts to potentiate glucocorticoid, androgen, and progesterone receptor signaling pathways. The aim of these studies was to identify and characterize FKBP52-specific inhibitors that would not only serve as tools for the pharmacological analysis of FKBP52-receptor interactions, but may also lead to novel drugs with significant …
