Also in these cell lines, HRG1-β1 and/or EGF partially recovered cell ability to grow in the presence of PHA (Additional file 2), suggesting that HER family activation can interfere with MET targeting in gastric cancer cells (the poor response to HRG1-β1 observed in Hs746T cells is paralleled by the low expression of HER2/HER3 in this cell line (Additional file 1). Here, EGF is linked to gastric cancer.
