New open-source software judges accuracy of algorithms that predict tumour evolution
OICR-led international research group develops new open-source software to determine the accuracy of computational methods that can map the genetic history of tumour cells.
A cancer patient’s tumour is often made up of many cells with different genetic traits that can evolve over time. Interest in tumour evolution has grown over the last decade, giving rise to several new computational tools and algorithms that can characterize genetic diversity within a tumour, and infer patterns in how tumours evolve. However, to date there has been no standard way to compare these tools and determine which are most accurate at deciphering these data.
The genetic differences between tumour cells can tell us a lot about a patient’s disease and how it evolves over time – Adriana Salcedo
In a study recently published in Nature Biotechnology, an OICR-led international research group released new open-source software that can be used to judge the accuracy of these novel algorithms.

Open source in open science: Accelerating cancer research (Part 1)
In the effort to bring better disease prevention and treatment to patients faster, cancer researchers are thinking more creatively about ways to conduct high-quality scientific research. Concerns about the quality, efficiency and reproducibility of research have motivated the open science movement – the growing trend of making data, methods, software and research more accessible to the greater scientific community.
Open source software (OSS), a major component of open science, enables research groups to reduce redundant efforts in software engineering by sharing software code and methods. In addition to improving efficiency, OSS promotes high-quality research by enabling collaboration, and helps make research easier to reproduce by making it more transparent.

OICR’s Cancer Genome Collaboratory wins 2018 OpenStack Superuser award for contributions to the cancer research community
Based on popular vote and review by the Superuser Editorial Advisory Board, OICR’s Cancer Genome Collaboratory team has won the 2018 OpenStack Vancouver Summit Superuser Award. The Award recognizes OICR’s use of OpenStack, an open-source software platform for cloud computing, to enable cancer research worldwide. Previous winners of the Superuser Award include AT&T, CERN and Comcast.
“We’re proud to be recognized by the greater research community that we support,” Vincent Ferretti, Director and Senior Principal Investigator, Genome Informatics at OICR, says. “OpenStack has helped us contribute to the cancer research community in Ontario, across Canada and internationally.”

Novel approach yields four robust biomarkers for breast cancer drug response
Biomarkers that can help predict a patient’s response to a given drug are central to testing new therapies in clinical trials as well as selecting which drugs to use in the clinic. Some of the biomarkers in use today rely on the overall expression of a given gene to predict if a drug will be of benefit. While these types of biomarkers have aided cancer research and treatment, a group led by Dr. Benjamin Haibe-Kains recently published research that is ushering in a new class of biomarkers – those based on gene isoforms (the different expression of the same gene within an individual). This work opens the door to more precise biomarkers.

New software uses machine learning to identify mutations in tumours without reference tissue samples
One of the main steps in analyzing cancer genomic data is to find somatic mutations, which are non-hereditary changes in DNA that may give rise to cancer. To identify these mutations, researchers will often sequence the genome of a patient’s tumour as well as the genome of their normal tissue and compare the results. But what if normal tissue samples aren’t available?

International collaboration cooks up powerful new software: MISO
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).

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.

Doing things differently: The story behind the promising chemical probe developed by OICR and the Structural Genomics Consortium
A recent collaboration between researchers at OICR and the Structural Genomics Consortium (SGC) used a new open-source approach to early stage drug discovery to develop and share without restrictions a drug-like molecule (or chemical probe) called OICR-9429 in an effort to crowd-source cancer research. OICR-9429 specifically inhibits a protein called WDR5 and can be used to investigate its function in a cell.
“Testing a new cancer treatment takes significant time and resources and unfortunately many attempts fail late in the development process. Also, most of the research activities are carried out in parallel and without enough collaboration. This leads to the duplication of a great amount of effort and raises the cost of cancer drugs that do make it to the clinic,” explains Dr. Cheryl Arrowsmith, Chief Scientist at SGC Toronto.
