Custom monoclonal antibody reveals HER2+ breast cancer target
Sep 07 2023
AMSBIO has supplied a tailor-made monoclonal antibody (mAB) to TU Dortmund researchers in Germany. This mAB aims to decode EDI3's role in breast cancer development, how it's controlled by HER2 signalling, and its therapeutic potential.
HER2+ breast cancer, marked by excessive Human Epidermal Growth Factor Receptor 2 (HER2) expression, is an extremely aggressive cancer subtype. Despite advancements in HER2-targeted therapies, the persistence of treatment resistance, both acquired and inherent, necessitates exploration of alternative therapeutic targets.
Targeting EDI3: A Potential Therapeutic Strategy for HER2-Positive Breast Cancer
Under the leadership of Dr Rosemarie Marchan, a group of researchers has undertaken an extensive study to investigate the clinical significance of EDI3, a glycerophosphodiesterase enzyme linked to choline metabolism, within HER2-positive breast cancer. They utilised the custom monoclonal antibody against EID3, provided by AMSBIO, in their research.
Dr Marchan commented: “We have tested many off-the-shelf antibodies over the years, with little to no success. We have also contracted companies to create a custom antibody for us, but again with limited success. Therefore, we are very thankful a few years ago that we were able to get a great antibody against EID3 from AMSBIO. Using this precious antibody our team has been able to demonstrate that inhibiting EDI3 in ER-HER2+ breast cancer cells resistant to HER2-targeted therapy reduces viability and tumour growth.”
