Medulloblastoma, the most common form of pediatric brain cancer, is the focus of this project, particularly those cases where the tumor recurs. The knowledge of the pathways and genes that can drive tumors to either progress/recur or be sensitive to treatment can be key for effective cancer treatment. To do this, researchers need to understand the variety within the cancer cells and the cell clones that survive treatment and/or metastasize. Additionally, the knowledge of the interactions between the tumor cells and its microenvironment (the conditions around a cell) is often critical to uncovering the mechanisms of tumor survival. Researchers propose to analyze 17 flash frozen tissue samples and 4 tissue in freezing media samples provided by the Children’s Brain Tumor Network to define cells and genes critical for Medulloblastoma recurrence/progression. Single cell technologies have the potential to substantially propel discovery in the understanding of medulloblastoma cancer biology. Researchers hypothesize that characterization of the cellular and genetic landscape of recurrent/progressive medulloblastomas will reveal important relationships that could lead to the advancement of therapeutic strategies.
What are the goals of this project?
Researchers will analyze medulloblastoma samples in an effort to understand cellular relationships that lead to progression and/or recurrence using techniques that map individual cancer cells.
What is the impact of this project?
Medulloblastoma is the most common form of pediatric brain cancer and this project will propel understanding of its biology leading to advancements in treatment options.
Why is the CBTN request important to this project?
High quality specimens are needed to carry out the work described in this project, and the Children’s Brain Tumor Network will support researchers through provision of such samples.
The Children's Brain Tumor Network contributed 17 flash frozen tissue samples and 4 tissue in freezing media samples for single-cell profiling.
