Examples include RPs L7a, L37 and S14 in prostate tumors and cell lines [ 20 ] ; RPs L5, L7A, L18, S3, S6, S8, S12, S13, S28, P0 and P1 in colorectal cancers and cell lines [ 21 22 23 24 25 26 ] ; L5 in astrocytomas [ 27 ] ; L18a in squamous cell carcinoma [ 28 ] ; L19 in breast tumors that over-express erbB-2 [ 29 ] ; RPs S3A, S4, and S17 in lymphoid malignancies [ 30 ] ; L38, S4, P0, and P1 in rhabdomyosarcoma cell lines [ 31 ] ; and P0, P1, P2, L5, L9, L35, L39, S3A, S10, and S17 in liver tumors [ 32 ] . In addition, as noted above, a recent SAGE study identified targets of N-myc in a human neuroblastoma cell line [ 18 ] . Of 114 up-regulated genes detected, 66 encoded RPs with elevations ranging from 40% to 37-fold.
On the same two-dimensional view, we plotted one dataset of 86 profiles from lung adenocarcinomas and another dataset of 45 profiles from glioblastomas and astrocytomas, generated from previous global gene-expression studies [ 5 6 ] . Figure 1shows this principal components analysis (PCA) plot of the gene-expression profiles from cell cultures, xenografts, and human lung and brain tumors.
We have previously demonstrated the overexpression and hormone-independent activation of the IGF-IR in primary breast cancers [ 42 ] . Similar overexpression of the IGF-IR and the ligands IGF-I and IGF-II have been seen in human gliomas and astrocytomas [ 43 44 45 46 ] . Because of the important role for the IGF-IR in cell survival, we investigated whether a dominant negative IGF-IR could inhibit growth of the U87 glioma.
The idea that the IGF-IR might be a valuable target for the treatment of brain tumors is supported by a recent pilot study in twelve patients with malignant astrocytomas [ 56 ] . All patients had grade 3 or 4 astrocytomas and had failed on standard therapy.
