TEL AVIV, Israel--(BUSINESS WIRE)--Compugen Ltd. (NASDAQ:CGEN) announced today the discovery and experimental verification of CGEN-438, a potential blood based biomarker for lung cancer. CGEN-438 is novel splice variant peptide of delta-like protein 3 precursor (DLL3). Importantly, the Compugen discovered biomarker is a peptide that is secreted from the cell into the bloodstream, whereas the previously known DLL3 is a protein located on the cell membrane. Initial clinical evidence indicates that the Compugen discovered molecule could potentially serve as both a serum biomarker for the diagnosis of small cell lung cancer and as a component in a biomarker combination for the diagnosis of non-small cell lung cancer patients.
