LDHA and familial pancreatic carcinoma: Based on the immunohistochemical staining results of the pancreas from the Human Protein Atlas database, we found that the protein expression of TES, LDHA, and ANXA2 was not expressed in normal pancreatic tissues, whereas medium and high expression levels of these genes were observed in pancreatic cancer tissues (Figure 6), which was in agreement with the mRNA results from the TCGA-PAAD dataset.
