Mastering Mutagenesis

DNA mouse

The world today is riddled with carcinogens and harmful mutagens ranging from the food we eat to the ever increasingly scorching sun rays. Environmental hazards seem to be all around us. How do these environmental influences actually change our DNA? How do our bodies respond to that change? These are all great questions and ones that are being studied worldwide as you read this.

Dr. Roger Woodgate and his team at the Laboratory of Genomic Integrity in the National Institute of Child Health and Human Development in Bethesda, Maryland have focused their careers on understanding the molecular mechanisms of damage-induced mutagenesis.

Under ideal conditions, the reliability of DNA replication is quite good. Approximately one error occurs in every 10 billion bases replicated. As one is continually subjected to a variety of endogenous and exogenous DNA damaging agents, optimal conditions rarely occur. Even though all organisms have evolved elaborate repair pathways to deal with such damage, these repair pathways never operate with 100% efficiency. As a consequence, the persisting DNA lesions are replicated, but with much lower fidelity than undamaged DNA.

The aim of Dr Woodgate’s research is to understand the molecular mechanisms by which mutations are introduced into damaged DNA and how it facilitates both evolution and species stability. This process is known as translesion DNA synthesis (TLS) and is facilitated by one, or more, of the "Y-family" of DNA polymerases that are conserved from bacteria to humans. These studies span the evolutionary spectrum and include studies in bacteria, archaea and eukaryotes, utilising yeast, human cells, and mouse models.

In addition to working on his important research, Dr Woodgate recently organised two Zing Conferences, one on DNA Polymerases in Cambridge, UK, and the other on Genomic Integrity in Cairns, Australia. The conference in Cairns focused on the various pathways that help protect living creatures from the genetic changes that lead to genomic instability, mutagenesis, inherited rare human diseases, cancer, premature ageing and neurological disorders. The next conference will be held in Dublin, Ireland, 9-12 July 2017. For more information closer to the date, please keep an eye on the Zing Conferences website.

Ozgene's Big History Project

Frank's blog – Lean ideology was introduced into the Ozgene culture back in 2009. At that time, we had several different departments within the company with set people to do each part. Each staff member had a “specialty”. Information was stored, but not analysed. Projects had become increasingly more complex and so had our processes. We were due for a change.
