| Research Abstract |
Immunohistochemical staining revealed that in neuroblastoma (NB), differentiating cells showed strong cytoplasmic staining. Expression of WT1 was higher in mature ganglionic cells, and in the immunohistochemical analysis, the WT1 positivity for ganglioneuromas was significantly higher than that for neuroblastomas. Knockdown of WT1 gene promoted the proliferation of NB69 cells (P<.01).The WT1 may govern cell differentiation and suppress cell proliferation in NB. The WT1 does not act as an oncogene, but it may participate in the maturation of NB, therefore can be a potential therapeutic target for cell differentiation.
