Single-cell multi-omic analyses resolve the cellular diversity of ALK/ROS1/MET/NTRK-fused gliomas in infants and older children

Andrea J. De Micheli, Carlos O.A. de Biagi-Junior, Costanza Lo Cascio, Charbel Machaalani et autres

Pediatric cancers are thought to arise from dysregulation of developmental programs, otherwise tightly regulated in time and space. Infant-type hemispheric gliomas (IHGs) arise in early childhood, driven by characteristic ALK/ROS1/MET/NTRK receptor tyrosine kinase (RTK) gene fusions. We dissected the cellular hierarchies of …

Multidimensional profiling of heterogeneity in supratentorial ependymomas

Daeun Jeong, Sara G. Danielli, Kendra K. Maaß, David R. Ghasemi et autres

Supratentorial ependymomas are aggressive childhood brain cancers that retain features of neurodevelopmental cell types1 and segregate into molecularly and clinically distinct subgroups2,3, suggesting different developmental roots. The developmental signatures, as well as microenvironmental factors, underlying aberrant cellular transformation and behaviour across each …
