Neuroblastoma is a childhood cancer of the sympathetic nervous system. Recent studies have shown that neuroblastoma tumors are composed of two cell identities, i.e. the adrenergic and mesenchymal identity. Both identities are driven by a core regulatory transcriptional circuitry, which acts as an autoregulatory positive feedforward loop, to delineate the cell identity through regulation of its target genes. We identified the long non-coding RNA NESPR to be specifically expressed in neuroblastoma cells of the adrenergic cell identity.
