Characterization And Target Identification Of Ak301: A Novel Mitotic Arrest Agent, Michael J. Bond, Avijeet S. Chopra, Marina Bleiler, Michelle Yeagley, Eric Scocchera

University Scholar Projects

The Giardina Laboratory has recently identified AK301 as a novel mitotic arrest agent. This work aimed to characterize the arrest state induced by AK301 (EC₅₀ ~ 150nM) and identify the cellar targets responsible for the arrest. It was found that AK301 arrest is readily reversible upon withdrawal of AK301. Cells that slip from mitosis after removal of AK301 are sensitized to apoptosis. This was found to be unique for AK301 when compared to other mitotic arrest agents like colchicine, vincristine, and BI2536. Arrested cells were found to have increased ATM activity as well as an upregulation of p53 and …

Non-Thermal Atmospheric Plasma Induces Ros-Independent Cell Death In U373mg Glioma Cells And Augments The Cytotoxicity Of Temozolomide, Gillian Conway, Alan Casey, Vladimir Milosavljevic, Yupeng Liu, Orla L. Howe, Patrick Cullen, James Curtin

Articles

Non-thermal atmospheric plasma (NTAP) is an ionised gas produced under high voltage that can generate short-lived chemically active species and induce a cytotoxic insult in cancer cells. Cell-specific resistance to NTAP-mediated cytotoxicity has been reported in the literature. The aim of this study was to determine whether resistance against NTAP could be overcome using the human glioma cell line U373MG.

Methods:

Non-thermal atmospheric plasma was generated using a Dielectric Barrier Device (DBD) system with a maximum voltage output of 120 kV at 50 Hz. The viability of U373MG GBM cells and HeLa cervical carcinoma cells was determined using morphology, flow …
