Polymerase chain reactions (PCR) are one of the most common tools used in molecular biology labs worldwide. This technique allows researchers to amplify, or increase, the amount of DNA in a sample so that they have more to work with. To keep track of the original molecules from a sample, chemical ‘barcodes’ are added. While barcodes serve an important purpose they can lead to errors and interfere with results. To prevent these cross-reactions a small team of international researchers have devised an ingenious method to ‘hide’ the barcodes when needed, leading to increased sensitivity and more reliable results.

Genetic tests are being used more commonly in the diagnosis of many types of cancer. However, there currently isn’t a highly accurate test that can identify men with aggressive forms of prostate cancer, making it more difficult to choose the most appropriate course of treatment.

New molecular barcode technology reduces error rate in genomic sequencing to 1 in 10,000
Toronto (March 9, 2017) – Researchers at the Ontario Institute for Cancer Research (OICR), together with international collaborators, have invented a technique to avoid a major problem with common laboratory techniques and improve the sensitivity of important cancer tests.

Digital Detection Tool Will Be Shared Freely Over the Web
Toronto, ON and Baltimore, MD (February 23, 2017) A research team from the United States and Canada has developed and successfully tested new computational software that determines whether a human DNA sample includes an epigenetic add-on linked to cancer and other adverse health conditions.

Keeping track of samples and organizing their associated data is a crucial part of the research process. Like many labs around the world, those at OICR were using a commercially available Laboratory Information Management System (LIMS) to perform this task. However, the researchers using it found that this tool placed far too many constraints on their work. So what did they do? They built their own in partnership with the Earlham Institute (EI) in the U.K. This collaboration has resulted in powerful, flexible and open source software called MISO (Managing Information for Sequencing Operations).

The ability to sequence and study the human genome and the genomes of different cancer types has allowed scientists to increase our understanding of the biology of these diseases. In turn this has helped to create new preventative strategies, diagnostic and prognostic tools as well as better treatments. But what if there was a way to make this information even more useful? An international group is working to establish a project that will do just that.

What does a beaver’s genome look like? And how can understanding the beaver genome help us to improve human health? A group of Canadian researchers led by Drs. Stephen Scherer and Si Lok at The Centre for Applied Genomics and The Hospital for Sick Children today published the sequenced genome of the Canadian beaver in order to answer these questions and others (and just in time for Canada’s 150th anniversary, no less).
Dr. Jared Simpson led a team at OICR who provided their bioinformatics expertise on the project. We spoke to Simpson about his team’s role in the study and how their findings could contribute to a better understanding of cancer.

The Global Alliance for Genomics and Health’s (GA4GH) Beacon Project has partnered with ELIXIR, the body that organizes Europe’s infrastructure for life science data, to make genomic data in that continent more easily discoverable by researchers. The Beacon Project is a demonstration project that enables genomic data centres to make their data more easily discoverable to users by allowing them to use simple queries to explore a dataset’s contents.

A team of researchers and clinician-scientists from across Canada have discovered a signature of 41 mutations that are common in prostate cancer and will help to prevent patients with non-aggressive disease from being overtreated. Dr. Paul Boutros, a Principal Investigator in OICR’s Informatics and Bio-computing Program and Co-Lead of the Canadian Prostate Cancer Genome Network (CPC-GENE), answered a few questions about how the signature was developed and its potential impact on patients.

The base components of DNA – adenine, thymine, cytosine and guanine (commonly referred to as ATCG) are so fundamental to the study of genetics that they are probably familiar to anyone who has taken a high school biology class. Now, one team of researchers has expanded the ‘DNA alphabet’ to help aid in efforts to learn how cancers develop.

OICR-led study finds four unique genomic signatures in pancreas cancer, uncovers potential of immunotherapies
Pancreas cancer is one of the most aggressive and deadly forms of the disease. According to the Canadian Cancer Society, only 8 percent of pancreas cancer patients survive more than five years after diagnosis. OICR’s PanCuRx Translational Research Initiative has recently published the results of an international collaboration that increases understanding of this complex disease and how to treat it based on a patient’s unique profile.

Reactome releases 10,000th annotated human protein, a major milestone that will benefit research community
Open source tools like Wikipedia and Google Maps help us get things done faster in our daily lives. In the same way, researchers rely on a variety of open source tools to help them make discoveries faster. Reactome (www.reactome.org) is one such tool. Researchers use it because it relates human genes, proteins and other biomolecules to the biological pathways and processes in which they participate, helping to facilitate new cancer research breakthroughs. Earlier this month Reactome reached a major milestone when it released its 10,000th annotated human protein to the research community. We spoke to OICR’s Dr. Robin Haw, who is Project Manager and Outreach Coordinator at Reactome, about the history of the project, the importance of this particular milestone and where the project is headed next.
