Radiation-induced mitotic catastrophe in PARG-deficient cells.
Poly(ADP-ribosyl)ation is a post-translational modification of proteins involved in the regulation of chromatin structure, DNA metabolism, cell division and cell death. Through the hydrolysis of poly(ADP-ribose) (PAR), Poly(ADP-ribose) glycohydrolase (PARG) has a crucial role in the control of life-and-death balance following DNA insult. Comprehension of PARG function has been hindered by the e...
متن کاملCatastrophe Archetypes
We propose an Integrated Systemic Theory of Catastrophes (ISTC) using System Dynamics to model and to understand common systemic structures and behaviours of catastrophes. Current catastrophe research concentrates on a specific field and does not capture complex multi-field catastrophe scenarios that cannot be reduced to a single scientific field. For example, when looking at famines the elemen...
متن کاملElectromechanical Catastrophe
A transducer is a system that couples two loads. For example, an electromechanical transducer couples a mechanical force and an electrical voltage. A two-load, nonlinear system can exhibit rich behavior of bifurcation, which can be displayed in a three-dimensional space, with the horizontal plane representing the two loads, and the vertical axis representing the state of the system. In this thr...
متن کاملDo Firms Manage Catastrophe and Non-Catastrophe Risks Differently?
Recent disasters and historical insurance payouts have triggered renewed interest in how firms manage their left-tail exposure. Using a unique dataset of fully described insurance policies purchased by large U.S. firms, we provide the first consistent estimates of premium elasticity of corporate demand for insurance for both catastrophe and noncatastrophe risks. We do so by combining this datas...
متن کاملAlterations in gene expression during radiation-induced mitotic catastrophe in HeLa Hep2 cells.
AIM To explore kinetic changes in the gene expression profile during radiation-induced mitotic catastrophes. MATERIALS AND METHODS Gene expression changes were measured in HPV-infected HeLa Hep2 tumor cells following exposure to 5 Gy of ionizing radiation ((60)Co). Signaling pathways were explored and correlated to the biological responses linked to mitotic catastrophe. RESULTS Following ir...
