Expression alterations define unique molecular characteristics of spinal ependymomas (2015)
Journal Article
Lourdusamy, A., Rahman, R., & Grundy, R. G. (2015). Expression alterations define unique molecular characteristics of spinal ependymomas. Oncotarget, 6(23), https://doi.org/10.18632/oncotarget.3715

Ependymomas are glial tumors that originate in either intracranial or spinal regions. Although tumors from different regions are histologically similar, they are biologically distinct. We therefore sought to identify molecular characteristics of spin... Read More about Expression alterations define unique molecular characteristics of spinal ependymomas.

Combined hereditary and somatic mutations of replication error repair genes result in rapid onset of ultra-hypermutated cancers (2015)
Journal Article

DNA replication?associated mutations are repaired by two components: polymerase proofreading and mismatch repair. The mutation consequences of disruption to both repair components in humans are not well studied. We sequenced cancer genomes from child...

Germ-line and somatic DICER1 mutations in pineoblastoma (2014)
Journal Article

Germ-line RB-1 mutations predispose to pineoblastoma (PinB), but other predisposing genetic factors are not well established. We recently identified a germ-line DICER1 mutation in a child with a PinB. This was accompanied by loss of heterozygosity (L...

Processed pseudogenes acquired somatically during cancer development (2014)
Journal Article

Cancer evolves by mutation, with somatic reactivation of retrotransposons being one such mutational process. Germline retrotransposition can cause processed pseudogenes, but whether this occurs somatically has not been evaluated. Here we screen seque...

RHPS4 G-quadruplex ligand induces anti-proliferative effects in brain tumor cells (2014)
Journal Article
Lagah, S., Tan, I.-L., Radhakrishnan, P., Hirst, R. A., Ward, J. H., O'Callaghan, C., …Rahman, R. (2014). RHPS4 G-quadruplex ligand induces anti-proliferative effects in brain tumor cells. PLoS ONE, 9(1), Article e86187. https://doi.org/10.1371/journal.pone.0086187

Background
Telomeric 3’ overhangs can fold into a four-stranded DNA structure termed G-quadruplex (G4), a formation which inhibits telomerase. As telomerase activation is crucial for telomere maintenance in most cancer cells, several classes of G4...

Metrics and textural features of MRI diffusion to improve classification of pediatric posterior fossa tumors (2013)
Journal Article

Metrics and textural features of MRI diffusion to improve classification of pediatric posterior fossa tumors. American Journal of Neuroradiology, 35(5), https://doi.org/10.3174/ajnr.A3784

BACKGROUND AND PURPOSE: Qualitative radiologic MR imaging review affords limited differentiation among types of pediatric posterior fossa brain tumors and cannot detect histologic or molecular subtypes, which could help to stratify treatment. This st... Read More about Metrics and textural features of MRI diffusion to improve classification of pediatric posterior fossa tumors.

The role of the WNT/β-catenin pathway in central nervous system primitive neuroectodermal tumours (CNS PNETs) (2013)
Journal Article

Background: Central nervous system primitive neuroectodermal tumours (CNS PNETs) are embryonal tumours occurring predominantly in children. Current lack of knowledge regarding their underlying biology hinders development of more effective treatments...

Serial MR diffusion to predict treatment response in high-grade pediatric brain tumors: a comparison of regional and voxel-based diffusion change metrics (2013)
Journal Article
Rodriguez Gutierrez, D., Manita, M., Jaspan, T., Dineen, R. A., Grundy, R. G., & Auer, D. P. (in press). Serial MR diffusion to predict treatment response in high-grade pediatric brain tumors: a comparison of regional and voxel-based diffusion change metrics. Neuro-Oncology, 15(8), https://doi.org/10.1093/neuonc/not034

Background

Assessment of treatment response by measuring tumor size is known to be a late and potentially confounded response index. Serial diffusion MRI has shown potential for allowing earlier and possibly more reliable response assessment in a...
