Safeguarding Genetic Integrity for Preclinical Research with Rodent Models: Processes and Technologies
Genetic integrity of rodent breeding colonies has a direct and fundamental impact on the quality of preclinical research. Without a robust breeding program which incorporates husbandry best practices, colony refreshment strategies, along with monitoring techniques, critical studies can be undermined by strain contamination, genetic drift and expression changes. These challenges apply to all rodent research, but small GEM colonies are often most at risk.
Are there surprises hiding in your GEM colonies? Different types of mutations, such as randomly integrated transgenes and CRISPR mutants, require different approaches to genetic monitoring. Strain background can have an unexpected impact on the phenotypic expression of certain mutations, including altering disease severity. Taconic's SNP service often identifies unexpected strain findings in imported lines for biomedical researchers with whom we work.
Join this webinar series to discover how Taconic Biosciences applies robust strategies to assess, monitor, and maintain genetic quality in both commercial animal model colonies and customer breeding projects. Discover how you can take these strategies and apply them to your own breeding projects. We will provide guidance on best practices ranging from technical solutions, to key husbandry practices and colony refreshment strategies that support genetic quality.
This series includes two webinars:
Webinar Series | Part 1
February 29
Learn about foundational concepts of genetics in colony management including: background strain and substrain as well as strain contamination; genetic drift as it applies to both inbred and outbred lines; generation number and pedigree; and the use of cryopreservation and line refreshes to stop the clock on genetic changes.
Get insight into strategies to identify and mitigate genetic risk, including key husbandry practices to safeguard genetic quality from Taconic Senior Manager, Genetic Sciences and Compliance, Dr. Bart Smits.
Webinar Series | Part 2
March 28
Get insight into genetic monitoring strategies, including the use of coat color and physical observations as a low-tech monitoring strategy, and the selection of physical colony location based on risk factors such as coat color, strain background, and gene of interest.
Dive deeper into exciting new strategies to better safeguard colonies, including transgene sequencing, monitoring of transgene integrity via copy number and expression testing, monitoring observations, and whole genome sequencing (WGS) in inbred strain refreshes or identification of spontaneous mutations. Learn how to mitigate the impact of genetic integrity disruptions and identify and manage off-target mutations resulting from CRISPR-mediated gene editing.
