| Research Abstract |
Neuroblastoma is an aggressive solid tumor that accounts for approximately 15% of all cancer-related deaths in children. More than half of high-risk neuroblastoma patients are estimated to experience relapses and their overall survival rates remain less than 40%. Identification of a new prognostic factor is essential to improve the prognosis of neuroblastoma patients. Aberrant alternative splicing is intimately associated with an increasing number of cancers, and its use as a new diagnostic and/or prognostic biomarker has attracted considerable attention. In the present study, we identified four alternatively spliced isoforms of Rab15, originally isolated as a brain-specific Rab protein. Rab15 isoform balance correlated with differentiation of neuroblastoma tumor-initiating cells(TICs) and Rab15 alternative splicing may serve as a biomarker to discriminate TICs from non-TICs in neuroblastoma.
