(Figure 2) To give an example: sarcoma cell lines resistant to BMS 536924 (small molecule IGF-1R tyrosine kinase inhibitor) expressed high levels of IGFBP-3 and IGFBP-6 whereas the sensitive ones showed high expression level of IGF-1 and IGF-2 [16]. The gene discussed is IGFBP6; the disease is sarcoma.
