Background: Medulloblastoma, ependymoma, and pilocytic astrocytoma are common pediatric posterior fossa tumors. These tumors show overlapping characteristics on conventional MRI scans, making diagnosis difficult. Purpose: To investigate whether appar...

Journal Article
Alfardus, H., de los Angeles Estevez Cebrero, M., Rowlinson, J., Lourdusamy, A., Abdelrazig, S., Ortori, C., …Smith, S. (2021). Intratumour heterogeneity in microRNAs expression regulates glioblastoma metabolism. Scientific Reports, 11(1), Article 15908. https://doi.org/10.1038/s41598-021-95289-9

While specific microRNA (miRNA) signatures have been identified in glioblastoma (GBM), the intratumour heterogeneity in miRNA expression has not yet been characterised. In this study, we reveal significant alterations in miRNA expression across three... Read More about Intratumour heterogeneity in microRNAs expression regulates glioblastoma metabolism.

Introduction Surgery and radiotherapy are established childhood ependymoma treatments. The efficacy of chemotherapy has been debated. We report final results of the SIOP Ependymoma I trial, with 12-year follow-up, in the context of a post-hoc analys... Read More about EPEN-04.

Journal Article
Griesinger, A., Riemondy, K., Donson, A., Willard, N., Prince, E., Harris, F., …Ritzmann, T. (2021). EPEN-07. SINGLE-CELL RNA SEQUENCING IDENTIFIES A UNIQUE MYELOID SUBPOPULATION ASSOCIATED WITH MESENCHYMAL TUMOR SUBPOPULATION IN POOR OUTCOME PEDIATRIC EPENDYMOMA. Neuro-Oncology, 23(Supplement 1), i14-i15. https://doi.org/10.1093/neuonc/noab090.057

We have previously shown immune gene phenotype variations between posterior fossa ependymoma subgroups. PFA1 tumors chronically secrete IL-6, which induces secretion of myeloid cell IL-8 and pushes the infiltrating myeloid cells to an immune suppress... Read More about EPEN-07. SINGLE-CELL RNA SEQUENCING IDENTIFIES A UNIQUE MYELOID SUBPOPULATION ASSOCIATED WITH MESENCHYMAL TUMOR SUBPOPULATION IN POOR OUTCOME PEDIATRIC EPENDYMOMA.

We have previously shown the importance of immune factors in posterior fossa ependymoma (PF EPN). Recently, we found eight transcriptionally unique subpopulations of myeloid cells infiltrating PF EPN with one population particularly enriched in PFA1... Read More about EPEN-08.

EPEN-11. TUMOR DIFFERENTIATION IMPACTS THE BIOLOGY OF RECURRENCE IN CHILDHOOD POSTERIOR FOSSA EPENDYMOMA (2021)
Journal Article

Ependymoma (EPN) of childhood is curable in only 50% of cases, with recurrences in the remainder that are refractory to treatment. In recent years significant advances have been made in understanding the molecular and cellular biology of EPN. Recent... Read More about EPEN-11.
