Abstract
CD44, a cancer-associated membrane glycoprotein involved in cell adhesion and tumor progression, has been implicated as a cancer stem cell antigen in several cancers including breast cancer. If the detection sensitivity of CD44 as an early marker for cancer could be improved, this would have important clinical applications. As compared with early stage treatments of other kinds of cancer, treatment of breast cancer is more likely to results in positive outcomes, so this early detection is crucial. Therefore, CD44 is a potential diagnostic target for cancer detection. Herein, we have used a peptide library to screen novel diverse peptides that bind to CD44 with high affinity and characterized the specific binding of these peptides. Our work provides a basis to develop novel diagnostic peptides which may replace antibodies as CD44 detection probes.
