The ABCG2 antibody targets the ATP-binding cassette subfamily G member 2 (ABCG2), a transmembrane transporter protein also known as breast cancer resistance protein (BCRP). ABCG2 plays a critical role in multidrug resistance (MDR) by actively effluxing chemotherapeutic agents, such as mitoxantrone and topotecan, out of cells, thereby reducing intracellular drug accumulation and compromising treatment efficacy. This protein is expressed in normal tissues, including the placenta, liver, and intestinal epithelium, where it functions in xenobiotic detoxification and protection against toxins.
In cancer research, ABCG2 antibodies are widely used to study its overexpression in drug-resistant tumors, such as leukemia, breast, and lung cancers, as well as in cancer stem cells (CSCs) that drive tumor recurrence. These antibodies enable detection of ABCG2 via techniques like Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF), aiding in the assessment of its localization and expression levels. Clinically, ABCG2 expression is linked to poor prognosis and therapeutic resistance, making it a potential biomarker for predicting treatment outcomes.
The development of ABCG2 antibodies has also advanced research into circumventing MDR, including the design of inhibitors to block its efflux activity. However, challenges remain in standardizing detection methods and understanding its complex regulation across cancer types.
