Isolated monophosphorylated peptide derived from human alpha-enolase useful for diagnosis and treatment of pancreatic adenocarcinoma, antibodies directed against the said monophosphorylated peptide, and uses thereof

Abstract

An isolated peptide of 12-20 amino acids in length comprising the amino acid sequence SEQ ID NO:1, wherein the serine residue (S) at position 8 of SEQ ID NO:1 is phosphorylated, is provided. Also provided is a human monophosphorylated alpha-enolase isoform wherein the serine residue (S) at position 419 of the human alpha-enolase amino acid sequence (SEQ ID NO:2) is phosphorylated and in which other post-translational modifications may be present. Further provided are antibodies capable of specifically binding the peptide and/or the isoform of the invention. The peptide, the isoform and the antibodies of the invention may be used in the diagnosis and/or amelioration and/or treatment of pancreatic adenocarcinoma.
