EPIGENETIC ALTERATIONS AS THERAPEUTIC TARGETS IN PEDIATRIC BRAIN TUMORS

We and others co-discovered the presence of activating mutations in ACVR1 in 25% of human DIPGs in 2014. Subsequently, my laboratory has developed a murine DIPG model incorporating R206H ACVR1 and observed that R206H ACVR1 significantly accelerates brainstem gliomagenesis. In addition, short-term treatment with a bone morphogenetic protein pathway inhibitor (...

Validation of TAK228 as an effective drug for treating children ...

Validation of TAK228 as an Effective Drug for Treating Children Diagnosed with DIPG Diffuse intrinsic pontine glioma (DIPG) is an untreatable childhood cancer.  DIPGs develop in pons making them surgically unresectable.  We and others have identified mutations in histone and their obligate partner mutations that seem to drive ...

MRI Guided Focused Ultrasound: Targeted Drug Delivery in Diffuse Intrinsic ...

Hypothesis & Anticipated Results Diffuse Intrinsic Pontine Glioma, (DIPG) is a fatal cancer and the leading cause of death from  brain tumours in young children. Despite numerous existing chemotherapeutic agents and  promising new molecular therapies, one overriding challenge remains: to overcome the blood  brain barrier (BBB) and ...

POLYAMINE PATHWAY METABOLISM AS A NOVEL THERAPEUTIC OPTION FOR DIFFUSE ...

Diffuse intrinsic pontine glioma (DIPG) is the most aggressive of all childhood cancers. Standard treatment with radiotherapy is only palliative and chemotherapy has been found ineffective. Polyamines are organic compounds essential for key functions of living cells. They can be made by human cells but also generated from intestinal microorganisms ...

Developing Novel Combination theraputic approaches for DIPG targeting Polo-like Kinase 1

Whole genome sequencing on DIPG biopsy and autopsy samples have identified specific mutations in Histone H3, ACVRI, TP53 and ATRX causing heterochromatin silencing, genetic instability and alterations in DNA damage response pathways. Using a unique panel of patient derived DIPG cultures, we have further examined the molecular profile of DIPG ...
