Project: "Systematic proteomic profiling and subclassification of Glioblastoma”

Location: University Health Network

Generously funded by the Richard Motyka Brain Tumour Research Fellowship
 

About the project:

Glioblastoma (GBM) is a brain tumour with a patient median survival period of 15 months, a clinical outcome that has remained unchanged over the last 40 years. Recent molecular profiling efforts have established that DNA mutations in a gene called IDH1/2 result in improved patient survivals beyond 5 years. However, such DNA mutations only represent a minority of GBM patients (5-10%) and thus novel molecular approaches are needed to further subclassify and provide more superior prognostic and therapeutic approaches. I will use state of the art mass spectrometry-based global proteomic analysis to define GBM subgroups based on their protein make-up. Analysis of epidemiologically defined group of 200 primary GBM samples of varying patient outcomes, from short to long term survivors, will be used to define proteomic diagnostic predictors of patient survival, in tumours lacking definitive genomic mutation classifications. Furthermore, identification of proteomic signatures with more refined GBM classifications will establish a platform for assessing pharmacologic effectiveness on proliferation and cancer stem cell identities of tissue culture models of GBM. Collectively, our research proposal aims to yield novel molecular predictors of patient outcomes that offer an avenue for more patient-specific pharmacological interventions and ultimately result in improved GBM patient treatment.

Read what being awarded this Fellowship means to Ugljesa:

Being awarded the Richard Motyka Brain Tumour Research Fellowship means that I can continue to pursue my passionate career of finding better treatment options for glioblastoma brain tumour patients. 

Although genomics-based breakthroughs have made moderate impacts on improving patient diagnosis, overall glioblastoma survival rates have remained stagnant over the last twenty years.

With the generous support of this fellowship I can focus on utilizing the newest available proteomics technologies to further understand this devastating cancer and improve patient outcomes as a result. Indeed, mass spectrometry-based proteomic efforts have shown promise in other tumour types as a superior profiling method to understand abnormal tumour-related biological pathways. Translating this technology has potential in further subdividing glioblastoma tumours into distinct subtypes and thus could uncover previously unrecognizable treatment approaches. 

As a medical researcher, I always strive to generate results that can positively affect patient outcomes and I am tremendously grateful for the generosity of the Motyka family and the Brain Tumour Foundation of Canada for their continued support of the brain tumour research field.

Where our footsteps lead...

We remain inspired by the bravery and perseverance of the brain tumour community, including kids like 6-year-old Joshua, who completed the Brain Tumour Walk just two weeks after brain surgery for a Dysembryoplastic Neuroepithelial Tumour. Read from Joshua's Dad's perspective about their brain tumour journey.
