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...
BACKGROUND Positive HER2 status identifies breast carcinomas that might respond to trastuzumab treatment. Manual HER2 fluorescent in situ hybridisation (FISH) is the most readily used method to detect HER2 gene amplification which defines positive HER2 status in addition to HER2 protein overexpression. Automation of HER2 FISH may improve HER2 gene testing. The aim of our study was to evaluate a...
Abstract Objectives We compared the clinicopathologic features, clinical management, and outcomes of human epidermal growth factor receptor 2 (HER2)–expressing nonexpressing microinvasive breast carcinomas (MiBC) to explore significance HER2 in MiBC. Methods Clinicopathologic follow-up information cases with final diagnosis MiBC known status between 2007 2019 were analyzed. Results Nineteen (41...
The promise of antibodies as mediators of effective targeted anticancer therapy is beginning to be fulfilled. In the past few years, two monoclonal antibodies (MAbs) have been approved for selective use by the U.S. Food and Drug Administration (FDA) (Rockville, MD) and incorporated into standard therapy, resulting in improved clinical responses and prolongation of life. The most dramatic clinic...
Chromogenic immunohistochemistry (IHC) is omnipresent in cancer diagnosis, but has also been criticized for its technical limit in quantifying the level of protein expression on tissue sections, thus potentially masking clinically relevant data. Shifting from qualitative to quantitative, immunofluorescence (IF) has recently gained attention, yet the question of how precisely IF can quantify ant...
Chemokines are relevant molecules in shaping the tumor microenvironment, although their contributions to tumorigenesis are not fully understood. We studied the influence of the chemokine CX3CL1/fractalkine in de novo breast cancer formation using HER2/neu transgenic mice. CX3CL1 expression was downmodulated in HER2/neu tumors, yet, paradoxically, adenovirus-mediated CX3CL1 expression in the tum...
Trastuzumab is an iconic rationally designed targeted therapy for HER2-positive breast cancers. However, the low response rate and development of resistance call for novel approaches for the treatment of patients. Here, we report that concurrent targeting of tumor cells and activation of T cells in the tumor microenvironment results in a synergistic inhibitory effect on tumor growth and overcom...
Chimeric antigen receptor T (CAR-T) cells have demonstrated promising results against hematological malignancies, but have encountered significant challenges in translation to solid tumors. To overcome these hurdles, we have developed a switchable CAR-T cell platform in which the activity of the engineered cell is controlled by dosage of an antibody-based switch. Herein, we apply this approach ...
