Mapping the lineage-retained antigen landscape in neuroblastoma

Neuroblastoma is among the deadliest pediatric solid tumors, and relapse is frequently driven by lineage plasticity between adrenergic (ADRN) and mesenchymal (MES) cell states that escape conventional and targeted therapies. This project aims to identify tumor antigens that are retained across both lineage states and are therefore suitable for T-cell–based immunotherapy resistant to lineage switching, including non-canonical antigens derived from the "dark proteome." To support this aim, we generated paired RNA-sequencing and ribosome profiling (Ribo-seq) data from neuroblastoma cell lines, patient-derived tumor organoids, and primary patient tumors spanning ADRN and MES states. The RNA-seq data enable custom transcriptome assembly to recover non-reference and non-canonical transcripts, while Ribo-seq maps actively translated canonical and non-canonical open reading frames at codon resolution. Together these data provide the molecular substrate for systematic discovery of lineage-retained, translation-supported neuroblastoma antigens.

Dataset ID	Description	Technology	Samples
EGAD00001016123	This dataset contains ribosome profiling (Ribo-seq) data generated to map actively translated open reading frames, including non-canonical ORFs from the "dark proteome", in neuroblastoma, supporting the identification of translation-validated tumor antigens. Ribosome-protected mRNA fragments (~28–30 nt) were isolated from 47 neuroblastoma samples comprising cell lines, patient-derived tumoroids, and primary patient tumors spanning the adrenergic (ADRN) and mesenchymal (MES) lineage states. Libraries were prepared following a modified version of the McGlincy & Ingolia 2017 protocol and sequenced single-end (1x50 bp) on the Illumina NextSeq 2000 platform. Raw data are provided as single-end fastq.gz	Illumina NovaSeq 6000 NextSeq 2000	47
EGAD00001016124	This dataset contains bulk RNA-sequencing data generated to enable custom transcriptome assembly and to provide expression context for matched ribosome profiling in the discovery of lineage-retained neuroblastoma tumor antigens. RNA was sequenced from 183 neuroblastoma samples comprising cell lines, patient-derived tumor organoids, and primary patient tumors spanning the adrenergic (ADRN) and mesenchymal (MES) lineage states, with 101 samples prepared as rRNA-depleted (total RNA) libraries and 82 samples prepared as poly(A)-selected libraries. Libraries were sequenced paired-end (2x150 bp) on the Illumina NovaSeq 6000 platform. Raw data are provided as paired-end fastq.gz files.	Illumina NovaSeq 6000 NextSeq 2000	82
