1 Our previous studies showed that HPS stimulates proliferation of hepatocytes in an ERK pathway-dependent manner. hps EPH receptor B2 Homo sapiens
2 However, the molecular mechanism of HPS-induced activation of the ERK pathway remains unclear. hps EPH receptor B2 Homo sapiens
3 Specific inhibition of EGFR kinase activity by gefitinib or down-regulation of EGFR by specific EGFR siRNAs prevented HPS-induced activation of the ERK pathway and proliferation of L02 cells. hps EPH receptor B2 Homo sapiens
4 Furthermore, inhibition of Src activity significantly blocked HPS-induced activation of the EGFR, which was suggestive of a ligand-independent transactivation mechanism of EGFR itself as well as ERK phosphorylation and proliferation of L02 cells. hps EPH receptor B2 Homo sapiens
