Histone methyltransferase PRDM9 promotes survival of drug-tolerant persister cells in glioblastoma

Chemotherapy often kills a large fraction of cancer cells but leaves behind a small population of drug-tolerant persister cells. These persister cells survive drug treatments through reversible, non-genetic mechanisms and cause tumour recurrence upon cessation of therapy. Here, we report a drug tolerance mechanism regulated by the germ-cell-specific H3K4 methyltransferase PRDM9. 

Comparative analysis of malignant pleural effusion and peripheral blood reveals unique T cell signatures associated with survival in mesothelioma patients

The success of cancer immunotherapies has highlighted the importance of monitoring the anti-tumour T cell response. Patients with mesothelioma frequently present with a malignant pleural effusion (MPE) that is commonly drained regularly to alleviate symptoms. As MPE contains tumour cells, T cells and cytokines, it provides a unique opportunity to sample immune events at the tumour site.

Unusual paediatric spinal myxopapillary ependymomas: Unique molecular entities or pathological variations on a theme?

We describe two unusual cases of MPE and use DNA methylation analyses to compare their signatures to try and distinguish if these represent a unique subset.

A Pre-Clinical Assessment of the Pan-ERBB Inhibitor Dacomitinib in Pediatric and Adult Brain Tumors

Glioblastoma in adults, and medulloblastoma and pineoblastoma that mainly affect children, are aggressive brain tumors.

Medulloblastoma

Medulloblastoma is a highly malignant small round blue cell tumor of the posterior fossa

The case for DNA methylation based molecular profiling to improve diagnostic accuracy for central nervous system embryonal tumors (not otherwise specified) in adults

We report the case of a 45-year-old woman who was diagnosed with a NOS based on immunohistochemical analysis of the patient's tumor at diagnosis.

Irreversible growth plate fusions in children with medulloblastoma treated with a targeted hedgehog pathway inhibitor

We report on 3 children treated with vismodegib who developed widespread growth plate fusions that persist long after cessation of therapy.

A novel technique of serial biopsy in mouse brain tumour models

Here we describe a method by which serial biopsy can be used to validate response to dacomitinib treatment in vivo using a mouse glioblastoma model

Recurrent MET fusion genes represent a drug target in pediatric glioblastoma

We identified previously unidentified gene fusions involving the MET oncogene in pediatric glioblastoma

Immunogenicity and clinical effectiveness of the trivalent inactivated influenza vaccine in immunocompromised children undergoing treatment for cancer

The trivalent inactivated influenza vaccine is safe, immunogenic, provides clinical protection and should be administered annually to immunosuppressed children receiving treatment for cancer
