Anti-BQ (BQ323636.1) antibody, clone D12
Breast cancer is the most common female cancer. About 70% of breast cancer is estrogen receptor positive (ER+). Tamoxifen is an effective and common drug for adjuvant treatment. However, up to 50% of the ER+ breast cancer eventually develop resistance to tamoxifen. A robust biomarker that can reliably predict which cancers will develop tamoxifen resistance is of particular importance. BQ323636.1 is a splice variant of NCOR2 . It contains 362 amino acids with a molecular mass 42.6 kDa. The detection of nuclear overexpression of BQ323636.1 by immunohistochemistry (IHC) in primary breast tumors was found to be strongly associated with the development of tamoxifen resistance (p=1.79 x 10-6; sensitivity: 52.9%, specificity: 72.0%) . The antibody may be used in the clinical setting for predicting tamoxifen response of ER+ breast cancer patients.
