p185(her2/neu) belongs to the ErbB receptor tyrosine kinase family, which has been associated with human breast, ovarian, and lung cancers. Targeted therapies employing ectodomain-specific p185(her2/neu) monoclonal antibodies (mAbs) have demonstrated clinical efficacy for breast cancer. Our previous studies have shown that p185(her2/neu) mAbs are able to(More)
HRG-beta1 stimulation of breast cancer cell line SKBR3 resulted in not only increased cell migration and invasion, upregulation of some mesenchymal markers, and downregulation of epithelial marker, but also upregulation of transcription factor Snail and its nuclear translocation. Similar results were acquired for cells transfected with Snail cDNA.(More)
Human epidermal growth factor receptor 2 (HER2) is one of the most studied tumor-associated antigens for cancer immunotherapy. An engineered anti-HER-2 chimeric A21 antibody (chA21) is a chimeric antibody targeted to subdomain I of the HER2 extracellular domain. Here, we report the anti-tumor activity of the novel engineered monoclonal antibody humanized(More)
Background -Anti-angiogenic biologicals represent an important concept for the treatment of vasoproliferative diseases. However, the need for continued treatment, the presence of non-responders and the risk of long-term side-effects limit the success of existing therapeutic agents. While Tspan12 has been shown to regulate retinal vascular development,(More)
AIM To explore the possibility of RNA interference (RNAi)-based gene therapy against HER2-overexpressing tumors using adenovirus-mediated vector. METHODS A plasmid named pHER2-GFP containing HER2 and green fluorescent protein (GFP) fusion was constructed and cotransfected into CHO-K1 cells respectively with nine small interference RNA (siRNA)-expressing(More)
