In the present study the potential regulation of the IGF-I receptor (IGF-I-R) gene by PAX3-FKHR at the transcriptional level was investigated.     ///    Transcriptional regulation of IGF-I receptor gene expression by the PAX3-FKHR oncoprotein..     ///    "PAX3-FKHR was able to transactivate the IGF-I-R promoter in sarcoma-derived cell lines, whereas PAX3 exhibited a reduced potency in comparison to the fusion protein. "    ///    "Furthermore, transfection of the chimera induced a significant increase in the endogenous levels of IGF-I-R protein, suggesting that the IGF-I-R gene is a physiologically-relevant molecular target for the PAX3-FKHR oncogene..
