April Meeting

Join us virtually on Wednesday, April 14, at 4:30 PM to learn more about quite interesting bioinformatics subjects. You will have the pleasure to hear,

  • Mathieu Bourgey, Insights into single cell sequencing analysis (in French)
  • Maria Virginia Ruiz Cuevas, Most Non-canonical Proteins Uniquely Populate the Proteome or Immunopeptidome

Mathieu, Bioinformatics manager at the Canadian Centre for Computational Genomics (C3G), will give an overview of the technical aspects of single cell sequencing data analysis.

Maria Virginia will present how she uses sequencing data to identify, characterize and quantify non-canonical proteins found in cancer cells. These proteins possessing distinct characteristics could make a critical contribution to tumor immunosurveillance.


We will use jitsi for the meeting (see the link on the Meetup Page).  The event will also be streamed on YouTube Live: https://youtu.be/Gqcut5NGpF0


You can register for the meeting on our  Meetup Page, or by sending an email to info@monbug.ca.  And contact us via Meetup or email if you would like to present to a future event.  We are always looking for enthusiast and enthusiastic presenters.

* Here is the complete summary of Maria Virginia’s talk:

Most Non-canonical Proteins Uniquely Populate the Proteome or Immunopeptidome  Significant evidence demonstrates the presence of unusual non-canonical proteins in cancer cells that appear to possess properties distinct from those of canonical proteins, making them important sources for the development of immunotherapies. Indeed, the immune system collects information about the health status of cells by reading protein fragments exposed on the cell surface. These fragments allow T cells to detect and eliminate cancer cells by reacting to the presence of unusual fragments. Because of their central role in cancer elimination, the identification of cancer-specific fragments is crucial for the design of vaccines that effectively stimulate the patient’s own immune system to fight the disease. My research therefore aims to elucidate the hitherto elusive rules of biogenesis of non-canonical proteins in cancer cells. To do so, I develop and use computational strategies to study sequencing data to identify, characterize and quantify these unusual proteins. This will provide novel information on the cellular processes of protein synthesis and folding in normal and cancer cells, and thus allow us to identify with high confidence cancer-specific actionable fragments that can be tested in therapeutic vaccines. 10.1016/j.celrep.2021.108815
