15th International Symposium on Paediatric Neuro-Oncology (ISPNO), Toronto, Canada
#DIPG: The biannual ISPNO meeting is the largest research conference dedicated to childhood brain tumours in the world, and we are pleased to be able to present a poster detailing our work on the DIPG Genomics Repository. If you are attending, please drop by poster number PG-32 on Monday 25th June between 18:15-21:00. Katy Taylor and Chris Jones will be on hand to discuss progress on the Repository and walk researchers through the analytical tools available. Hope to see you in Toronto!

First DIPG genomics data freeze and public release
We are pleased to announce the first public release of data from the International DIPG Genomics Repository. Although collection remains ongoing, we putting an intermediate freeze on the data in order to solicit feedback from the academic community. At the current time we have DNA copy number data for 94 cases of DIPG and 162 cases of non-brain stem paediatric high grade glioma available for analysis and download. We would welcome any comments and suggestions on how to improve the Repository and look forward to working with researchers around the world to make the most of this valuable data.
Chris Jones, Michael Baudis and Andre von Büren.

New PhD student joins Zurich group
Ni Ai, a new PhD student with a Master of Philosophy (Biomedical Engineering) from the University of Hongkong has joined the Zurich group. Besides working on technical aspects and systems biology of genomic data in cancer, Ni's disease specific projects will be centered in the area of childhood brain tumors, specifically DIPG and related entities. She will partially be supported through the grant from the "The Cure Starts Now" foundation.

Somatic histone 3 mutations in DIPG
Suzy
Baker’s group at St Jude Childrens Research Hospital in Memphis,
TN, USA, has just published in Nature
Genetics the first findings from the whole genome resequencing of
DIPG specimens as part of the St Jude / Washington University
Pediatric Cancer Genome Project. They made the startling discovery
that fully 78% of DIPG samples harboured mutations at a key residue
in two histone H3 variant genes – H3F3A and HIST1H3B.
Along with a concurrent publication in Nature by the groups of Nada Jabado (Montreal) and Stefan Pfister (Heidelberg) of H3F3A mutations in paediatric non-brainstem high grade glioma, we have the most definitive evidence of the biological distinctiveness of these lesions in the paediatric setting. Most intriguing is the different mutational spectrum in these genes between anatomical sites in children – K27 mutations are more common in DIPG than in supratentorial tumours, whilst G34 mutations were entirely absent from brainstem and thalamic lesions. Further investigating such biological differences remains a key goal of the DIPG Repository.

SIOP-Europe DIPG Network Meeting, Barcelona, Spain (Thursday 23rd – Friday 24th February 2012)
Clinicians and scientists interested in DIPG across Europe met recently in
Barcelona to discuss collaborative efforts to develop clinical trials
and biological studies in this terrible disease. Chris Jones and Katy
Taylor, a PhD student in his lab focusing on DIPG, attended the
meeting and presented on the progress of the DIPG Genomics
Repository. There is much enthusiasm for developing this resource
given the rarity of the tumour, and we are carrying out a census of
DIPG samples, data and ongoing research throughout the continent in
order to identify opportunities to work together to speed up progress
on a multinational basis.
