AMSBIO has supplied a custom monoclonal antibody (mAB) to researchers at the TU Dortmund** in Germany to unravel the role of EDI3 in breast cancer development, its regulation by HER2 signalling, and its potential as a therapeutic target.

Characterized by the overexpression of the Human Epidermal growth factor Receptor 2 (HER2) - HER2+ breast cancer is a highly aggressive disease subtype. While HER2-targeted treatments have improved patient outcomes for this form of cancer, acquired and inherent resistance to these treatment remains a challenge, prompting investigations into alternative therapeutic targets.

The team of researchers, led by Dr. Rosemarie Marchan, has conducted an extensive study to explore the clinical relevance of EDI3 - a glycerophosphodiesterase enzyme involved in choline metabolism, in HER2-positive breast cancer using the custom mAB against EID3 prepared and supplied by AMSBIO.

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”.

Having supplied product to thousands of industrial and academic projects in the last 20 years - AMSBIO is today widely recognised as a leading provider of both off the shelf and custom antibodies. The company offers an informed high-quality service for the generation of custom monoclonal antibodies specific to your target antigen.
