Enhanced IGF1R gene expression constitutes a common feature of most human cancers. IGF1Rs in tumors have been characterized using competitive binding assays, affinity cross-linking, Northern blots, RNase protection assays, RT-PCR, or a combination of them. The table represents a partial list of tumors in which IGF1R is highly expressed.
