1 Our miRNA microarray data indicate that liver-specific miR-122 expression was significantly reduced in sorafenib-resistant cells. Sorafenib microRNA 122 Homo sapiens
2 Overexpression of miR-122 made drug-tolerant cells sensitive to sorafenib and induced apoptosis. Sorafenib microRNA 122 Homo sapiens
3 These results indicated that activation of IGF-1R by ectopic down-regulation of miR-122 counteracted the effects of sorafenib-induced apoptosis, thus conferring sorafenib resistance. Sorafenib microRNA 122 Homo sapiens
4 These results indicated that activation of IGF-1R by ectopic down-regulation of miR-122 counteracted the effects of sorafenib-induced apoptosis, thus conferring sorafenib resistance. Sorafenib microRNA 122 Homo sapiens
5 Our data imply that an intimate correlation between miR-122 and IGF-1R abnormal expression is a critical determinant of sorafenib tolerance. Sorafenib microRNA 122 Homo sapiens
