Tumor cells are often heterogeneous and contain subclones with genetic and epigenetic variations. One frontier of cancer study is how cancer subclones compete and cooperate during cancer development. Medulloblastomas (MB), the most common childhood malignant brain tumor, are highly heterogeneous between different tumors and within a single tumor, which complicates treatment options. Sonic hedgehog (SHH) type MBs compose 25% of all MBs and are characterized by elevated SHH signaling and a cerebellum granule neuron precursor (CGNP) cell-of-origin.
One important characteristic of MB is its significant association with epigenetic abnormalities, including those in the H3K27me3 methyltransferase P...
