Sprtn Metalloprotease As A Target To Sensitize Cancer Cells To Crosslinking Chemotherapy, Cole J. Turner
Sprtn Metalloprotease As A Target To Sensitize Cancer Cells To Crosslinking Chemotherapy, Cole J. Turner
Honors Theses
Bifunctional alkylating agents have demonstrated high clinical utility as a chemotherapeutic strategy against cancer. These compounds have been well-characterized for their capacity to exert cytotoxicity via interstrand DNA crosslinking. However, the same electrophilic chemistry can also form DNA-protein crosslinks (DPCs) whose contributions to these drugs’ antitumor effects have been less well-defined. Recently, the metalloprotease SPRTN has been implicated as a predominant mediator of DPC repair in mammalian cells. Previous work has demonstrated that SPRTN deficiency increases the sensitivity of cancer cells to DPC-inducing agents such as formaldehyde and cisplatin, but these findings have yet to be translated more broadly across …
Near Infrared Gumbos And Nanogumbos For Biomedical Applications, Mi Chen
Near Infrared Gumbos And Nanogumbos For Biomedical Applications, Mi Chen
LSU Doctoral Dissertations
Recent advances in development of nanomaterials have provided great opportunities for cancer research. In this dissertation, nanoGUMBOS derived from a group of uniform materials based on organic salts (GUMBOS) were investigated for several biomedical applications including chemotherapy, photothermal therapy (PTT), and drug delivery. GUMBOS are solid-phase organic salts consisting of bulky cations and anions. Similar to ionic liquids, GUMBOS display highly tunable properties with counter-ions variation, but with a defined melting point range of 25–250 °C. Nanomaterials derived from GUMBOS, i.e. nanoGUMBOS, display enhanced properties at the nanoscale level. This dissertation focuses on development of near infrared IR780 nanoGUMBOS for …
Paclitaxel Enhances Oncolytic Potential Of Herpes Simplex Virus Type-1 In Cancer Cells, Misagh Naderi
Paclitaxel Enhances Oncolytic Potential Of Herpes Simplex Virus Type-1 In Cancer Cells, Misagh Naderi
LSU Master's Theses
Taxanes are spindle poisons that bind to and stabilize microtubules resulting in mitotic arrest. Herpes simplex Typ-1 (HSV-1) virions utilize the microtubular network for intracellular transport during both virus entry and virus egress from infected cells. It has been reported previously that taxanes may synergize with oncolytic herpes simplex viruses in the treatment of experimental prostate and breast tumors in mice. Other reports have indicated that taxanes may inhibit viral replication in infected cells. In this study the previously characterized Oncolytic Herpes Simplex Virus type 1 (OSVP), which was constructed in Kousoulas lab was used in conjugation with paclitaxel (taxol) …
Effect Of Chemotherapeutic Treatment Schedule On A Tissue Transport Model, Dan E. Ganz
Effect Of Chemotherapeutic Treatment Schedule On A Tissue Transport Model, Dan E. Ganz
Masters Theses
Current chemotherapeutic treatment schedule prediction methods rely heavily on PK/PD-based models and overlook the important contribution of tissue-level transport and binding. Tissue-level transport and binding phenomena are essential to understanding drug delivery and efficacy in tumors. Drugs with desirable PK/PD properties often fail in vivo due to poor tissue-level transport. We developed an in silico method to predict the effect of treatment schedule on efficacy that couples PK/PD with tissue-level transport. Treatment schedules were implemented on theoretical drugs with different PK/PD and transport properties. For each drug with a given clearance rate, diffusivity, and binding, treatment schedules consisting of one …
Influence Of Oncotype Dx® On Chemotherapy Prescribing In Early Stage Breast Cancer Patients: A Claims-Based Evaluation Of Utilization In The Real World, Kenneth Neil Kennedy
Influence Of Oncotype Dx® On Chemotherapy Prescribing In Early Stage Breast Cancer Patients: A Claims-Based Evaluation Of Utilization In The Real World, Kenneth Neil Kennedy
Theses and Dissertations--Pharmacy
The decision for adjuvant therapy in women with early stage breast cancer (ESBC) has historically been guided by the presence or absence of specific biological markers (hormone and HER2 receptors), age, and extent of nodal involvement. Oncotype DX® is a validated assay that quantifies protein expression that can predict the risk of cancer recurrence. This study evaluates if the use of Oncotype DX® impacts chemotherapy prescribing in ESBC. This retrospective, cohort study identified patients with ESBC from a large commercially insured population from January 2007 through June 2009. Patients were identified as having ESBC by utilizing procedure and diagnosis codes …
