Research Abstract |
In childhood cancers, the tumors derived from abnormal differentiation show favorable outcomes, while highly malignant tumors contain cancer stem cells and have a high frequency of relapse. In the present study, we isolated cancer stem cells from neuroblastoma and hepatoblastoma samples and analyzed their characteristics using genomics and one cell proteomics(Cellomics). In these cancer stem cells, neurodifferentiative pathway and glutamate metabolism were inhibited but several molecules including Bim-1 and Notch-1 were up-regulated. Among these molecules, we identified the molecule which was elevated in serum of the cases with unfavorable outcomes. This molecule is considered as a useful candidate for detecting cancer stem cells in childhood cancer patients
