SHP-1 reverses trastuzumab resistance and migration in HER2-positive breast cancer cells through the stat3/p-stat3 pathw
Decreased expression of Src homology region 2 domain containing protein tyrosine phosphatase 1 (SHP-1) was found in human breast cancer cell lines and primary breast cancers. As a candidate tumor suppressor gene, the role of SHP-1 in HER-2-positive breast cancer remains to be elucidated. The aim of the present study was to investigate the effects of upregulated SHP-1 expression in reversing trastuzumab resistance and migration by HER-2-positive breast cancer cells, potentially providing a new target to trastuzumab resistance in anti-HER2 therapy.
