Targeting Of The Hedgehog Signaling Pathway In Cancer Treatment, Andrew J. Hawes
Targeting Of The Hedgehog Signaling Pathway In Cancer Treatment, Andrew J. Hawes
The Cardinal Edge
The Hedgehog (Hh) signaling pathway is a developmental pathway that is highly conserved evolutionarily. While typically only displaying high activity during embryogenesis, overactivation of the Hh pathway in adults has been linked to multiple forms of cancer including acute myeloid leukemia, myelofibrosis, basal-cell carcinoma, pancreatic ductal adrenal carcinoma, and triple negative breast cancer. The prevalence of Hh activation in many different cancers has made it a prime target for inhibition of these cancers through novel therapies. This literature review sought to assess the current state of cancer treatment through inhibition of Hh signaling. Most current clinical trials involving the pathway …

A Computational Model Of The Line-1 Retrotransposon Life Cycle And Visualization Of Metabolic Networks In 3-Dimensions., Michael D. Martin
Electronic Theses and Dissertations
Computational modeling of metabolic reactions and cellular systems is evolving as a tool for quantitative prediction of metabolic parameters and reaction pathway analysis. In this work, the basics of computational cell biology are presented as well as a summary of physical processes within the cell, and the algorithmic methods used to find time dependent solutions. Protein-protein and enzyme-substrate interactions are mathematically represented via mass action kinetics to construct sets of linear differential equations that describe reaction rates and formation of protein complexes. Using mass action methods, examples of reaction networks and their solutions are presented within the Virtual Cell simulation …

Electronic Theses and Dissertations
Paraoxonase 2 (PON2) is an intracellular, multifunctional enzyme with near-ubiquitous tissue distribution. Within cells, PON2 is localized to mitochondria and endoplasmic reticulum (ER), where it mitigates the formation of reactive oxygen species (ROS). PON2’s chief enzymatic function is its lactonase activity, through which it catalyzes the hydrolysis of a bacterial quorum-sensing molecule, N-(3-oxododecanoyl)-l-homoserine lactone (C12), effectively disrupting bacterial intercellular communication and protecting against infection. C12 is produced by the opportunistic pathogen Pseudomonas aeruginosa and has been shown to disrupt various aspects of eukaryotic host cell physiology and evoke apoptotic cell death through the activity of PON2. Additionally, PON2 has garnered …
