Title:
Abstract LB-326: The role of HER3 in HER2-amplified cancers other than breast cancers
Published date:
05/15/2020
Excerpt:
Lapatinib induced apoptosis correlated with HER3 activation. Tumor growth was reduced upon HER3 knockdown in HER2-amplified cancers other than breast cancers, particularly cancers with constitutive HER3 phosphorylation. Many HER2-amplified cancers of the breast (HCC1569, HCC1954, HCC1419, UACC732, SUM190), bladder (CLS-439), stomach (N87, OE19), esophagus (TE4, KYSE410), lung (Calu3), and endometrium (USPC-ARC1, USPC-ARC2) showed HER3 activation...
