Nanosecond Pulsed Electric Fields Induce A Mitochondria-Independent Apoptosis In B16f10 Melanoma Cells In Vitro, Wentia Elissa Ford
Theses and Dissertations in Biomedical Sciences
Nanosecond pulsed electric fields (nsPEFs) are ultra-short pulses that induce direct electric field and biological effects that initiate apoptosis. Here the application of ten 300ns pulses ranging in electric fields from 12kV/cm-60kV/cm was administered to determine the effects on B16F10 melanoma cells evaluated by in vitro studies. Initial application of nsPEFs demonstrated apoptosis induction in an electric field- and pulse number-dependent manner measured by caspase activation that correlated with decrease in cell viability 24hr post pulse. In addition caspase activity was shown to be independent of calcium mobilization though ions may play a part in other aspects of ...
Functional Analysis Of Ing1 And Ing4 In Cell Growth And Tumorigenesis: A Dissertation, Andrew H. Coles
GSBS Dissertations and Theses
The five member Inhibitor of Growth (ING) gene family has been proposed to participate in the regulation of cell growth, DNA repair, inflammation, chromatin remodeling, and tumor suppression. All ING proteins contain a PHD motif implicated in binding to methylated histones and are components of large chromatin remodeling complexes containing histone acetyltransferase (HAT) and histone deacetylase (HDAC) enzymes, suggesting a role for ING proteins in regulating gene transcription. Additionally, forced overexpression studies performed in vitro have indicated that several ING proteins can interact with the p53 tumor suppressor protein and/or the NF-кB protein complex. Since these two proteins play ...
