PPIA and cancer: Among them, 16 proteins were common to both cancer subtypes, while three (calreticulin (CALR), eukaryotic translation elongation factor 1 gamma (EEF1G), and YWHAZ protein (YWHAZ)) were unique for center vs. control and five (citrate synthase (CS), heat shock 70 kDa protein (HSPA1A), mitochondrial heat shock 60 kD protein (1 HSPD1), PPA1, and inorganic pyrophosphatase (PPIA) were unique to margin vs. control.
