TP53INP1 and neuroblastoma: To assess whether repression of TP53INP1 expression in neuroblastoma tissues can be used as a novel prognostic marker for poor prognosis and as a therapeutic target in neuroblastoma patients, we examined TP53INP1 gene expression in a cohort of 201 neuroblastoma cDNA samples from the Pediatric Oncology Group Neuroblastoma Biology Study [24].
