The six proteins, lactate dehydrogenase (LDHA), glyceraldehyde 3-P dehydrogenase (GAPDH), Hsp27 (HSPB1), proteasome activator subunit 2 (PSME2), pyruvate kinase (PKM2) and the annexins A4 and A5 (ANXA4 and ANXA5) have all been associated to at least one type of cancer (breast, colon, kidney, liver, lung, ovarian, pancreatic); this association is further confirmatory regarding the veracity of our data and analyses. Here, LDHA is linked to cancer.
