Targeting Cancer Stem Cells: A New Hope for Brain Tumor Treatment

Brain cancer often presents a notable challenge due to its late detection. By the time symptoms emerge, tumors can be complex and tough to understand.Researchers, though, are making strides in tackling this challenge, particularly in a specific subtype of medulloblastoma called sonic hedgehog (SHH) medulloblastoma.

A groundbreaking study published in Nature Communications sheds light on a critical protein, OLIG2, responsible for awakening “sleeping” stem cells.These awakened stem cells then divide, contributing to tumor formation and regrowth. Remarkably, blocking OLIG2 effectively prevents tumor growth and relapse. “our findings offer a novel strategy to target cancer stem cells, providing hope for more effective treatments against aggressive brain tumors,” explains Dr. Peter Dirks, Senior Scientist in the developmental, Stem cell & Cancer biology Program and Chief of the Division of Neurosurgery.

A Novel Approach: Intercepting Tumor Development at Its Source

The research team’s approach targets a crucial early stage in tumor development when cancer-initiating stem cells undergo specific transitions. By disrupting this process, they effectively intercept the entire tumor formation pathway. Dr. Kinjal Desai, a postdoctoral researcher in the Dirks lab, clarifies, “There is an order to how cancer-initiating stem cells undergo fate changes to form tumors. We can target an early transition event and intercept the entire process — essentially stopping the cancer in its earliest form.”

Scientists discovered a critical window of opportunity during which tumor progression can be halted. Combining a pre-existing treatment with a small molecule drug, CT-179, which disrupts OLIG2, successfully targeted residual stem cells after treatment, preventing their reawakening and subsequent tumor relapse.

Preclinical models demonstrate that CT-179 prevents tumor formation in early-stage SHH medulloblastoma and significantly increases survival rates. These findings,corroborated by simultaneous research published in Nature Communications from Children’s Healthcare of Atlanta and QIMR Berghofer Medical Research Institute in Australia,suggest this treatment strategy could revolutionize treatment options,not just for SHH medulloblastoma,but for other brain cancers like diffuse intrinsic pontine glioma (DIPG).

Precision Biology: Predicting, Preventing, and Treating Cancer

Building on previous research published in Nature, which illuminated the early stages of glioblastoma development, the Dirks lab is optimistic about the diagnostic potential of this discovery. While clinical trials for patients are still in the future, particularly for those at risk of relapse, Dr. Dirks states, “At SickKids, we’re already genetically testing every child with cancer to inform their diagnosis and treatments – our study goes beyond genetic testing to precision biology. I am excited for a future where this ‘magic bullet’ for early treatment could be combined with diagnostic tests to perhaps prevent the cancer from developing at all.”

This research is a testament to the dedication of scientists at sickkids,supported by organizations such as the Canadian Institutes of Health Research (CIHR),Ontario Institute for Cancer Research,Terry Fox Research Institute,Canadian Cancer Society,Cancer Research UK,Stand Up to Cancer,Jessica’s Footprint Foundation,Hopeful Minds Foundation,b.r.a.i.n.child, Meagan’s Walk, Garron Family Cancer Centre, the bresler Family, and the SickKids Foundation.

These breakthroughs hold immense promise for the future of brain tumor treatment, potentially offering personalized therapies tailored to specific patient profiles and preventing cancer formation altogether. The ongoing research spearheaded by Dr.Dirks and his team is a beacon of hope, paving the way for a brighter future for individuals facing the challenges of brain cancer.
