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)
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)
BACKGROUND Anti-angiogenic biologicals represent an important concept for the treatment of vasoproliferative diseases. However, the need for continued treatment, the presence of nonresponders, and the risk of long-term side effects limit the success of existing therapeutic agents. Although Tspan12 has been shown to regulate retinal vascular development,(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)
Cytokines are protein mediators that are known to be involved in many biological processes, including cell growth, survival, inflammation, and development. To study their regulation, we generated a library of 209 different cytokines. This was used in a combinatorial format to study the effects of cytokines on each other, with particular reference to the(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)
