Effect of treatment with trastuzumab for 8 days on the expression profile of HER and pHER receptors. All gastric cancer cell lines were treated for 8 days with 10 µg/ml trastuzumab; afterwards, the expression of EGFR, HER2, HER3, HER4, pEGFR, pHER2, pHER3 and pHER4 was determined via Western blot analysis. Basal expression of HER receptors varied highly between the cell lines. No obvious correlation between basal HER/pHER receptor expression and/or changes in expression and responsiveness to trastuzumab could be observed
