VEGFA and lung adenocarcinoma: Consequently, we collected cancerous and paracancerous tissues from seven pairs of lung adenocarcinoma patients and performed immunohistochemical staining for SLC2A1 and VEGFA (Figure 7A), and statistical analyses showed that the expression of SLC2A1 and VEGFA was significantly upregulated in lung adenocarcinoma tissues (Figures 7B, C), which was in agreement with the expression of SLC2A1 in the TCGA public database (Figure 7D).
