Figure 1. Immunohistochemical staining of PKM2 in lung adenocarcinoma specimens.

Figure 1

(A) Case 1: Tumor tissue with high PKM2 expression. Case 2: Tumor tissue with low PKM2 expression. Peritumoral tissues have low PKM2 expression (×200 magnification). (B) The mean PKM2 immunohistochemical staining score in lung adenocarcinoma tissue (3.96 ± 2.91) was significantly higher than that of matched peritumoral tissue (p < 0.05) (2.14 ± 1.94).
