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 (...

A MOUSE MODEL OF HIST1H3B / ACVR1 MUTANT DIPG

Diffuse intrinsic pontine glioma (DIPG) is a malignant brainstem tumour arising in children representing a major unmet clinical need, with a 2-year survival rate close to zero. With chemotherapy ineffective and surgical intervention not possible, new therapeutic approaches are urgently needed based upon the unique biological mechanisms driving DIPG tumorigenesis. ...

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 ...

Cellular Cybercriminals: DIPG Hacks into the Neural Communication Infrastructure

 My group has recently demonstrated the neuronal activity drives the growth of DIPG and other high-grade gliomas. One way that active neurons promote DIPG growth is through activity-regulated secretion of growth factors into the tumor microenvironment. We have now discovered an additional, surprising means of neuron:glioma communication – ...

Targeting neuronal activity-regulated DIPG infiltration (2015)

DIPG is characteristically infiltrative (i.e. diffuse and intrinsic), and this infiltrative/invasive behavior is destructive both in the brainstem and in other areas of the central nervous system to which DIPG spreads during the course of the disease. In work previously funded by the Cure Starts Now and the ...
