Gustavo Alencastro Veiga Cruzeiro: Diffuse hemispheric glioma, H3G34R/V-mutant
Mara Vinci, Chair of Biology SIOPE HGG Working Group, shared a post by Gustavo Alencastro Veiga Cruzeiro on LinkedIn, adding:
“Congratulations Gustavo Alencastro Veiga Cruzeiro, Ilon Liu, Lynn Bjerke, Rebecca Rogers and Mariella Filbin and Chris Jones for the amazing work !!
It has been a pleasure and an honour to contribute!”
Quoting Gustavo Alencastro Veiga Cruzeiro‘s post:
“Our recently published manuscript in Cancer Cell is out – Diffuse hemispheric glioma, H3G34R/V-mutant (H3G34-DHG).
I want to thank all our collaborators, including lab mates at Filbin Lab (Dana-Farber Cancer Institute), Mariella Filbin and Chris Jones lab for always believing in our work with perseverance. I want to extend a special appreciation to our co-leads, Ilon Liu, Lynn Bjerke, and Rebecca Rogers.
Key Insight: H3G34-DHG, a lethal brain tumor, shows similar patterns to developing interneurons.
Findings:
Tumor Origin: H3G34-DHG tumors may derive from interneuronal precursors with GABAergic traces
Cellular Hierarchy: Tumors mimic the spatial organization of progenitor cells in the developing brain.
CRISPR Screens: Identified genes crucial for tumor growth, with CDK6 being a major vulnerability.
Therapeutic Insights:
CDK4/6 Inhibitors and CDK6-Specific Degrader:
- H3G34-DHG tumor cells are more sensitive to these small molecules compared to other pediatric high-grade glioma subtypes.
- Promotes partial differentiation in H3G34-DHG tumor cells, reducing growth and extending survival.
Clinical Impact: We report a refractory patient with DHG-H3G34 experienced 17 months of stable disease on a CDK4/6 inhibitor.
Conclusion: Targeting CDK6 offers a promising new therapeutic avenue for treating H3G34-DHG
A final thanks to the Alex Lemonade Stand Foundation (ALSF) ‘A’ Award and Young Investigator, NIH Innovator Award (DP2), Sontag Foundation for funding this work.”
