Combined MYC and P53 defects emerge at medulloblastoma relapse and define rapidly progressive, therapeutically targetable disease.
Hill, RM; Kuijper, S; Lindsey, JC; Petrie, K; Schwalbe, EC; et al. (CELL PRESS, 2015-01-12)We undertook a comprehensive clinical and biological investigation of serial medulloblastoma biopsies obtained at diagnosis and relapse. Combined MYC family amplifications and P53 pathway defects commonly emerged at relapse, ... -
DIPG Harbors Alterations Targetable by MEK Inhibitors, with Acquired Resistance Mechanisms Overcome by Combinatorial Inhibition.
Izquierdo, E; Carvalho, DM; Mackay, A; Temelso, S; Boult, JKR; et al. (AMER ASSOC CANCER RESEARCH, 2022-03-01)UNLABELLED: The survival of children with diffuse intrinsic pontine glioma (DIPG) remains dismal, with new treatments desperately needed. In a prospective biopsy-stratified clinical trial, we combined detailed molecular ... -
Evaluating Imaging Biomarkers of Acquired Resistance to Targeted EGFR Therapy in Xenograft Models of Human Head and Neck Squamous Cell Carcinoma.
Baker, LCJ; Sikka, A; Price, JM; Boult, JKR; Lepicard, EY; et al. (FRONTIERS MEDIA SA, 2018-07-23)Background: Overexpression of EGFR is a negative prognostic factor in head and neck squamous cell carcinoma (HNSCC). Patients with HNSCC who respond to EGFR-targeted tyrosine kinase inhibitors (TKIs) eventually develop ... -
Evaluation of the Response of Intracranial Xenografts to VEGF Signaling Inhibition Using Multiparametric MRI.
Boult, JKR; Box, G; Vinci, M; Perryman, L; Eccles, SA; et al. (ELSEVIER SCIENCE INC, 2017-09-01)Vascular endothelial growth factor A (VEGF-A) is considered one of the most important factors in tumor angiogenesis, and consequently, a number of therapeutics have been developed to inhibit VEGF signaling. Therapeutic ... -
Infant High-Grade Gliomas Comprise Multiple Subgroups Characterized by Novel Targetable Gene Fusions and Favorable Outcomes.
Clarke, M; Mackay, A; Ismer, B; Pickles, JC; Tatevossian, RG; et al. (AMER ASSOC CANCER RESEARCH, 2020-07-01)Infant high-grade gliomas appear clinically distinct from their counterparts in older children, indicating that histopathologic grading may not accurately reflect the biology of these tumors. We have collected 241 cases ... -
Investigating intracranial tumour growth patterns with multiparametric MRI incorporating Gd-DTPA and USPIO-enhanced imaging.
Boult, JKR; Borri, M; Jury, A; Popov, S; Box, G; et al. (WILEY, 2016-11-01)High grade and metastatic brain tumours exhibit considerable spatial variations in proliferation, angiogenesis, invasion, necrosis and oedema. Vascular heterogeneity arising from vascular co-option in regions of invasive ... -
Investigating the Contribution of Collagen to the Tumor Biomechanical Phenotype with Noninvasive Magnetic Resonance Elastography.
Li, J; Zormpas-Petridis, K; Boult, JKR; Reeves, EL; Heindl, A; et al. (AMER ASSOC CANCER RESEARCH, 2019-11-15)Increased stiffness in the extracellular matrix (ECM) contributes to tumor progression and metastasis. Therefore, stromal modulating therapies and accompanying biomarkers are being developed to target ECM stiffness. Magnetic ... -
Metabolic biomarkers of response to the AKT inhibitor MK-2206 in pre-clinical models of human colorectal and prostate carcinoma.
Al-Saffar, NMS; Troy, H; Wong Te Fong, A-C; Paravati, R; Jackson, LE; et al. (NATURE PUBLISHING GROUP, 2018-10-30)BACKGROUND: AKT is commonly overexpressed in tumours and plays an important role in the metabolic reprogramming of cancer. We have used magnetic resonance spectroscopy (MRS) to assess whether inhibition of AKT signalling ... -

Burley, TA; Mączyńska, J; Shah, A; Szopa, W; Harrington, KJ; et al. (WILEY, 2018-06-01)Glioblastomas (GBMs) are high-grade brain tumors, differentially driven by alterations (amplification, deletion or missense mutations) in the epidermal growth factor receptor (EGFR), that carry a poor prognosis of just ... -
Noninvasive MRI Native T1 Mapping Detects Response to MYCN-targeted Therapies in the Th-MYCN Model of Neuroblastoma.
