“Very happy to announce our latest paper on pediatric/AYA glioma!
See tutorial from fantastic Gustavo Cruzeiro and Ilon Liu below – I’m so very proud of your resilience and dedication!
Biggest thanks to our fabulous collaborators from The ICR, Jones Lab ICR!! Chris, Rebecca, Lynn, Yura, Al – it was such a great joy working with you!!
A million thanks also to Michelle Monje for her unwavering support for this study, for always being my sounding board, and for the many fun G34-discussions and -dinners we had along the way.”
Quoting Gustavo Cruzeiro’s post:
“Our recently published manuscript in Cancer Cell – Diffuse hemispheric glioma, H3G34R/V-mutant (H3G34-DHG).
We resolve a putative hierarchy in H3G34-DHG along continuous interneuronal lineage development.
H3G34-DHG tumor cells mirror spatial nests of human embryonal interneurons development.
Integrating our single-cell findings with genome-wide CRISPR screens, we show that interneuronal lineage progenitor states present a distinct vulnerability in H3G34-DHG.
Of these, we focus on CDK6 as a top screen hit and clinically actionable target.
H3G34-DHG tumor cells are more sensitive to these small molecules compared to other pediatric high-grade glioma subtypes.
CDK6 targeting shifts H3G34-DHG towards more mature neuronal-like states and extends survival.
We report on a patient with progressive H3G34-DHG in whom treatment with a CDK4/6 inhibitor achieved 17 months of stable disease.
Thus, targeting CDK6 presents a promising avenue in H3G34-DHG for further translational study!
I want to thank all our collaborators, including lab mates at Mariella Filbin-Filbin Lab (Dana-Farber/Boston Children’s Cancer and Blood Disorders Center) and Chris Jones-Jones Lab ICR. I want to extend a special appreciation to our co-leads, Ilon Liu, Lynn Bjerke, and Rebecca Rogers.
A final thanks to the Alex Lemonade Stand Foundation, ‘A’ Award and Young Investigator, NIH Innovator Award (DP2), and the Sontag Foundation for supporting this work.”
