The latter included Alpha-Synuclein (aSyn) that is known to be associated with Parkinson's Disease [37], [38], [39], as well as proteins like Purine Nucleoside Phosphorylase (NP), Valosin Containing Protein (VCP), Thrombospondin-1(THBS1) etc, all of which were found to be elevated in PDAC-derived juice specimens.
