1 Treatment with linsitinib, a specific IR inhibitor, inhibited IR and downstream intermediates AKT, MAPK, and S6 in GIST430 and GIST48, but not in GIST882, exerting minimal effect on KIT phosphorylation in these cell lines. 3-(8-amino-1-(2-phenylquinolin-7-yl)imidazo(1,5-a)pyrazin-3-yl)-1-methylcyclobutanol insulin receptor Homo sapiens
2 Treatment with linsitinib, a specific IR inhibitor, inhibited IR and downstream intermediates AKT, MAPK, and S6 in GIST430 and GIST48, but not in GIST882, exerting minimal effect on KIT phosphorylation in these cell lines. 3-(8-amino-1-(2-phenylquinolin-7-yl)imidazo(1,5-a)pyrazin-3-yl)-1-methylcyclobutanol insulin receptor Homo sapiens
3 Additive effects showing increased apoptosis, antiproliferative effects, cell-cycle arrest, and decreased pAKT and pS6 expression, tumor growth, migration, and invasiveness were observed in imatinib-resistant GIST cells with IR activation after coordinated inhibition of IR and KIT by linsitinib (or IR shRNA) and imatinib, respectively, compared with either intervention alone. 3-(8-amino-1-(2-phenylquinolin-7-yl)imidazo(1,5-a)pyrazin-3-yl)-1-methylcyclobutanol insulin receptor Homo sapiens
