My research team strives to develop new diagnostic and therapeutic approaches to detect and treat children suffering from cancer earlier, better and with reduced impact on their life.
The fundamental question is how cancer cells are different from healthy, normal cells? If we understand this we will be able to better detect and kill cancer while leaving the rest of the body untouched.
Our research focuses on proteins, the structural and functional building blocks of a cell. To do this we combine genomics and proteomics, a technology that enables us to monitor all of the proteins in our body and detect how they are changed in childhood cancer. We then use computational approaches to further analyze and integrate our findings and to make them accessible to clinicians and fellow scientists around the world.

The overall objective of my team's research is to monitor and detect aberrant protein presence and function in cancer and exploit this difference to diagnose and treat cancer and improve the wellbeing of cancer survivors.
We are particularly interested in how the post-translational modification of proteins affects cancer progression and secondary disease, which can hit childhood cancer survivors years after successful treatment. After translation proteins can be modified by, for example, proteolytic processing or phosphorylation. This creates a repertoire of "proteoforms", which are all the variant and modified protein products of a single gene. They often differ in their localization, function and interaction with other proteins.
Our research program follows four main axes that inform each other:
I: We use proteo-genomics to study differences in tissue specimen from children suffering from select cancers and healthy individuals, and translate these findings into a new diagnostic and treatment approach.
II: We integrate cell biology, biochemistry, genomics, proteomics and bioinformatics to study the role of post-translational modification in the regulation of select cell signaling networks. By investigating patient-derived cells and mouse models we strive to identify new ways of altering these signaling networks to improve drug efficacy and reduce side effects.
III: Computational biology plays an integral role in our research. Our main focus is the development of algorithms for multi-scale data integraction, protein function analysis, pattern recognition and de-convolution of network effects in complex systems. Building on these we develop new biological knowledgebases and applications to improve the functional analysis of genomics and proteomics data and to guide personalized treatment decisions.
IV: We continuously strive to improve existing- and develop new technologies for the mass spectrometric analysis of complex biological specimen enabling a more comprehensive, specific and sensitive investigation of smaller biopsies.
My research team is embedded in the Michael Cuccione Childhood Cancer Research Program and affiliated with the BC Cancer Research Centre and BC Children’s Hospital. This creates a stimulating environment in which we work closely with world-class experts in clinical oncology, cancer biology, genomics and computer sciences.Grants
