1.Microenvironment-derived HGF overcomes genetically determined sensitivity to anti-MET drugs.

Cell-based drug screenings indicate that tumors displaying c-MET gene amplification are "addicted" to MET signaling and therefore are very sensitive to MET-targeted agents. However, these screenings were conducted in the absence of the MET ligand, hepatocyte growth factor (HGF), which is abundant in the tumor microenvironment. Sensitivity of six MET-addicted human tumor cells to three MET kinase inhibitors (JNJ-38877605, PHA-665752, crizotinib) and one antagonistic anti-MET antibody (DN30 Fab) was analyzed in the absence or presence of HGF, in a stroma-tumor coculture system, and by combining anti-MET drugs with an HGF neutralizing antibody (ficlatuzumab) in human HGF knock-in mice bearing c-MET-amplified tumors. In all models examined, HGF promoted resistance to MET-targeted agents, affecting both their potency and efficacy. HGF-induced resistance was due to restoration of physiologic GAB1-mediated PI3K activation that compensated for loss of aberrant HER3-dependent PI3K signaling.
2.Genetic and expression analysis of MET, MACC1, and HGF in metastatic colorectal cancer: response to met inhibition in patient xenografts and pathologic correlations.

Epub 2011 Mar 29.
PURPOSE: We determined the gene copy numbers for MET, for its transcriptional activator MACC1 and for its ligand hepatocyte growth factor (HGF) in liver metastases from colorectal carcinoma (mCRC). We correlated copy numbers with mRNA levels and explored whether gain and/or overexpression of MET and MACC1 predict response to anti-Met therapies. Finally, we assessed whether their genomic or transcriptional deregulation correlates with pathologic and molecular parameters of aggressive disease.
3.MET inhibitors in combination with other therapies in non-small cell lung cancer.
Padda S1, Neal JW1, Wakelee HA1. Transl Lung Cancer Res. 2012 Dec;1(4):238-53. doi: 10.3978/j.issn.2218-6751.2012.10.08.
MET and its ligand hepatocyte growth factor/scatter factor (HGF) influence cell motility and lead to tumor growth, invasion, and angiogenesis. Alterations in MET have been observed in non-small cell lung cancer (NSCLC) tumors, with increased expression associated with more aggressive cancer, as well as acquired resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI). MET inhibitors act via two basic mechanisms. Small molecule inhibitors antagonize ATP in the intracellular tyrosine kinase domain of MET, with studies on the following agents reviewed here: tivantinib (ARQ-197), cabozantinib (XL-184), crizotinib (PF-02341066), amuvatinib (MP470), MGCD265, foretinib (EXEL-2880), MK2461, SGX523, PHA665752, JNJ-38877605, SU11274, and K252A. The monoclonal monovalent antibody fragment onartuzumab (MetMAb) is also discussed here, which binds to and prevents the extracellular activation of the receptor by ligand. MET inhibition may both overcome the negative prognostic effect of MET tumor expression as well as antagonize MET-dependent acquired resistance to EGFR inhibitors.
4.Effectiveness of inhibitor rapamycin, saracatinib, linsitinib and JNJ-38877605 against human prostate cancer cells.
Li W1, Wang Z2, Wang L3, He X3, Wang G3, Liu H3, Guo F3, Wang Z4, Chen G2. Int J Clin Exp Med. 2015 Apr 15;8(4):6563-7. eCollection 2015.
To investigate the effect of different concentrations of inhibitors rapamycin, saracatinib, linsitinib and JNJ-38877605 on PC-3 cells with CCK-8 assay, respectively. PC-3 cells were incubated with different concentrations of rapamycin, saracatinib, linsitinib and JNJ-38877605, respectively, for 48 h at 37°C, the concentrations of rapamycin were 5 nM, 10 nM, 20 nM, 50 nM, 75 nM, 100 nM; Saracatinib: 0.125 nM, 0.25 nM, 0.5 nM, 1 nM, 2.5 nM, 5 nM; Linsitinib: 2 nM, 5 nM, 10 nM, 20 nM, 40 nM, 60 nM; JNJ-38877605: 0.125 nM, 0.5 nM, 1 nM, 2.5 nM, 5 nM, 10 nM. The proliferation of PC-3 cells was examined by CCK-8. Different concentrations of inhibitor rapamycin remarkably inhibited PC-3 cell proliferation after 48 h (P<0.05), inhibitory action did not change significantly from 5 nM-100 nM; different concentrations of saracatinib, linsitinib and JNJ-38877605 did not inhibit PC-3 cell proliferation after 48 h. Rapamycin treatment at low concentration can inhibit the proliferation of PC-3 cells, while saracatinib, linsitinib and JNJ-38877605 do not inhibit PC-3 cell proliferation.
