Latest work with IntechOpen by Michael Fasullo

Reactive oxygen species (ROS) and DNA double-strand breaks can result from mitochondrial defects and external sources, such as ionizing radiation. If not repaired properly, pathogenic mutations are generated. Human diseases resulting from inherited mitochondrial defects manifest in organs that physiologically require a high level of ATP synthesis. These diseases are clinically challenging, but new experimental clinical therapies include gene editing and mitochondrial transplants. Pathogenic ROS-associated cellular damage includes DNA double-strand breaks, and mouse models are now available to study multiple repair pathways. This book discusses the clinical manifestations of mitochondrial diseases in both the eye and the kidney, and presents new insights into double-strand break repair pathways and developmental phenotypes of g-ray-associated ontogenic mutations of Drosophila melanogaste.

Genotoxic Assays for Measuring P450 Activation of Chemical Mutagens

By Michael Fasullo

This review discusses using yeast as a model organism for studying the biological effects of P450-mediated metabolism of xenobiotics. We discuss the challenges of testing the safety of thousands of chemicals currently introduced into the market place, the limitations of the animal systems, the advantages of model organisms, and the humanization of the yeast cells by expressing human cytochrome P450 (CYP) genes. We discuss strategies in utilizing multiple genetic endpoints in screening chemicals and yeast strains that facilitate phenotyping CYP polymorphisms. In particular, we discuss yeast mutants that facilitate xenobiotic import and retention and particular DNA repair mutants that can facilitate in measuring genotoxic endpoints and elucidating genotoxic mechanisms. New directions in toxicogenetics suggest that particular DNA damaging agents may interact with chromatin and perturb gene silencing, which may also generate genetic instabilities. By introducing human CYP genes into yeast strains, new strategies can be explored for high-throughput testing of xenobiotics and identifying potent DNA damaging agents.

Checkpoint Control of DNA Repair in Yeast

By Michael Fasullo

Budding yeast has been a model organism for understanding how DNA damage is repaired and how cells minimize genetic instability caused by arresting or delaying the cell cycle at well-defined checkpoints. However, many DNA damage insults are tolerated by mechanisms that can both be error-prone and error-free. The mechanisms that tolerate DNA damage and promote cell division are less well-understood. This review summarizes current information known about the checkpoint response to agents that elicit both the G2/M checkpoint and the intra-S phase checkpoint and how cells adapt to unrepaired DNA damage. Tolerance to particular bulky DNA adducts and radiomimetic agents are discussed, as well as possible mechanisms that may control phosphatases that deactivate phosphorylated proteins.
