Optimization of Real Time PCR for Precise Measurement of HER2 Overexpression in Breast Cancer Specimens
Background: Breast cancer is one of the most prevalent malignancies among women in various countries. HER2 overexpression, which is due to different reasons, occurs in 20-30% of breast cancers. HER2 gene encodes an 185kDa transmembrane glycoprotein with 1255 amino acids. This active product triggers downstream intracellular signaling pathways inducing cell proliferation and cell survival. These...

متن کاملImmunogenicity of chimeric MUC1-HER2 vaccine against breast cancer in mice
Objective(s): Breast cancer is one of the most common cancers in the world and is on the increase. MUC1 and HER2 as tumor-associated antigens (TAAs) are abnormally expressed to some extent in 75–80% of breast cancers. In our present research, a novel chimeric MUC1-HER2 (HM) protein was designed and used to study whether an immune response can be generated against these TAAs. In vitro analysis ...

Background: Trichoepithelioma (TE) is a benign skin tumor with follicular differentiation, which sometimes is difficult to distinguish clinically and histologically from cutaneous basal cell carcinoma (BCC). An accurate diagnosis of these lesions is essential for effective and appropriate therapeutic decisions. Therefore, several attempts have been made to identify immunohistochemical differenc...
متن کاملAnalytical Validation of a Highly Quantitative, Sensitive, Accurate, and Reproducible Assay (HERmark®) for the Measurement of HER2 Total Protein and HER2 Homodimers in FFPE Breast Cancer Tumor Specimens
We report here the results of the analytical validation of assays that measure HER2 total protein (H2T) and HER2 homodimer (H2D) expression in Formalin Fixed Paraffin Embedded (FFPE) breast cancer tumors as well as cell line controls. The assays are based on the VeraTag technology platform and are commercially available through a central CAP-accredited clinical reference laboratory. The accurac...
