Introduction: ELISA is a sensitive, specific, reproducible and fast method to quantify the biological activity of antibodies. Trastuzumab is a humanized monoclonal antibody against HER2 receptors which prevents the initiation of downstream signaling pathway. Trastuzumab can be used as a positive control in the ELISA experiments for anti-HER2 antibodies. Additionaly, insufficient washing and blo...
Breast cancer remains one of the most frequent malignancies in women and primary cause cancer-related death all over world. Hormones tumor biomarkers have been implicated as possible causes prognostic breast cancer. The present study investigated use serum hormonal levels biomarkers; Carcinoembrvonic antigen (CEA), (CA 15-3) for diagnosis Cancer, generation different subtypes using Estrogen rec...
in this study, we synthesized herceptin conjugated magnetic nanoparticles (hmns) as an alternative probe to discover the levels of her2 (human epidermal growth factor receptor-2) in the surface of cells. these nanoparticles can be used by magnetic resonance imaging (mri) (non-invasive methods) for screening the patients with her2 positive or negative tumors. dextran coated iron oxide nanopartic...
Successful CAR T cell therapy for the treatment of solid tumors requires exemplary expansion, persistence and fitness, ability to target tumor antigens safely. Here we address this constellation critical attributes successful cellular by using integrated technologies that simplify development derisk clinical translation. We have developed a CAR-CD19 secretes CD19-anti-Her2 bridging protein. Thi...
Preclinical and early clinical studies have demonstrated that chimeric antigen receptor (CAR)-redirected T cells are highly promising in cancer therapy. We observed that targeting HER2 in a glioblastoma (GBM) cell line results in the emergence of HER2-null tumor cells that maintain the expression of nontargeted tumor-associated antigens. Combinational targeting of these tumor-associated antigen...
Background and Objective: Breast cancer is the fifth common cause of death in the world and is considered as the leading cause of cancer related death among females. HER2 is a surface antigen which is overexpressed in 30% of breast cancer cases. The aim of this study was cloning of HER2 receptor gene in pCDNA3.1Hygro+ expression vector, expression of this protein in LL2 eukaryotic cell line and...
PURPOSE CD11c is an antigen receptor predominantly expressed on dendritic cells (DC), to which antigen targeting has been shown to induce robust antigen-specific immune responses. To facilitate targeted delivery of tumor antigens to DCs, we generated fusion proteins consisting of the extracellular domain of human HER or its rat homologue neu, fused to the single-chain fragment variable specific...
Numerous targeted nanotherapeutics have been described for potential treatment of solid tumors. Although attention has focused on antigen selection and molecular design of these systems, there has been comparatively little study of how cellular heterogeneity influences interaction of targeted nanoparticles with tumor cells. Antigens, such as HER2/ERBB2, are heterogeneously expressed across diff...
Endostatin can inhibit angiogenesis and tumor growth in mice. A potential limitation of endostatin as an antitumor agent in humans is the short serum half-life of the protein that may decrease effective concentration at the site of tumor and necessitate frequent dosing. In an effort to improve antitumor activity, endostatin was fused to an antibody specific for the tumor-selective HER2 antigen ...
