Roles Of Resveratrol And Genistein In Invasion And Metastasis Of Breast Cancer, Brittany Wolfe
College of Science and Health Theses and Dissertations
Breast cancer is a cellular disease characterized by the exploitation of several cellular and molecular mechanisms involved in cell proliferation, apoptosis, motility, and invasion. Effective treatment is available for non-invasive breast cancer at diagnosis, leading to a very high survival rate compared to the low survival rate for those where the breast cancer has spread. Thus, identifying effective therapies and preventative agents is imperative to successfully treat breast cancer. Since diet compromises a large component of the risk factors for breast cancer, it would be beneficial to examine dietary compounds that could potentially play a beneficial role in inhibiting cancer …
A Study Of Histone Deacetylase Inhibitors: Determination Of The Binding Energetics Of Suberoylanilide Hydroxamic Acid With Zinc And Cobalt And Preliminary Screening Of Nitric Oxide Donors, Erin Gallagher
College of Science and Health Theses and Dissertations
Inhibiting histone deacetylases (HDACs) can suppress tumor cell growth eventually leading to their death, makeing HDACs an important drug target. Therefore, understanding the mechanism behind inhibiting HDACs is imperative. To determine the thermodynamic parameters for the interaction of a known competitive HDAC inhibitor, suberoylanilide hydroxamic acid (SAHA), with zinc(II), the metal ion in the HDAC active site, and cobalt(II), isothermal titration calorimetry (ITC) was used. The results showed that SAHA binds to zinc(II) more strongly than it does to cobalt(II) as the equilibrium binding constants were 4.3 ± 0.5 x 102 M-1 and 2.0 ± 0.5 x 10 …
