Conference Description

The helical nature of the double helix causes a topological problem for its replication. Watson and Crick were well aware of this potential problem, and in 1953 they stated: "Since the two chains in our model are intertwined, it is essential for them to untwist if they are to separate... Although it is difficult at the moment to see how these processes occur without everything getting tangled, we do not feel that this objection will be insuperable." We now know that this problem is solved by the DNA topoisomerases, which were first reported in 1971 by James Wang, with the discovery of bacterial topoisomerase I. Over the past ~40 years these enzymes have been found in all organisms (prokaryotes, eukaryotes, viruses and archaea) and to perform roles that are vital for survival, supporting replication, transcription and other processes where topological problems in DNA need to be resolved. The enzymes are ‘marvelous molecular machines’ catalyzing the seemingly magical task of passing one piece of DNA through another to catalyze changes in DNA topology. Some of the enzymes are molecular motors having the ability to transduce the free energy of ATP hydrolysis into torsional stress in DNA (supercoiling). Although the outline of their mechanisms has been established, a great deal is unknown and emerging technologies, such as single-molecule methods, need to be applied to gain a deeper understanding of these enzymes and their roles in cellular processes. Topoisomerases have also become key drug targets both for anti-bacterial and anti-cancer chemotherapy. This is due to their essential nature and because of their mechanism of action, which involves transient DNA cleavage that, if disrupted, can lead to highly cytotoxic events. Study of these enzymes in the context of myriad cellular processes is of key importance in research leading to the development of new chemotherapeutic agents.

The goal of this proposal is to establish a regular series of meetings centered on DNA topoisomerases. Activity over recent years confirms the fact that there is an ongoing appetite for conferences in this area. Around 1,000 papers concerned with topoisomerase have been published in each year in recent years, covering a wide range of topics. Previous relevant meetings have always attracted plenty of participants. The topic ‘DNA topoisomerases in biology and medicine’ will draw scientists in academia and pharma from a broad range of disciplines including structural biology, mechanistic enzymology, biophysics, genetics, pharmacology and cell biology, which will result in a fertile mix of ideas and approaches. By establishing a GRC in this area we aim to provide stability and continuity for meetings in this area going forward.

What is a GRC? Gordon Research Conferences (GRC) are 5-day meetings that bring scientists together from around the world to present and discuss unpublished research with other leaders in their field.

Related Conference

This Gordon Research Conference (GRC) series is related to the "DNA Topoisomerases in Biology & Medicine" Gordon Research Seminar (GRS) series. Although a related GRS will typically be scheduled in conjunction with its parent GRC each time it meets, that may not always be the case. Refer to the individual meetings in the Meeting History section below for more details. For more information about the associated Gordon Research Seminar (GRS) series, click here.

What is a GRS? Gordon Research Seminars (GRS) are 2-day meetings that bring graduate students and post-docs together to discuss their cutting edge research among peers and mentors. Each GRS immediately precedes an associated Gordon Research Conference (GRC), and topics addressed at the GRS relate closely to the GRC.
