Furthermore, the association between MCT-1 with CD31, CD163 and α-SMA gene expression was characterized using Lung cancer TissueScan qPCR arrays (Figure 7g), and the results showed that MCT-1 was positively correlated with CD31 (Pearson coefficient +0.31, P=0.03), CD163 (Pearson coefficient +0.37, P=0.01) and α-SMA (Pearson coefficient +0.32, P=0.03) in stage III/IV lung cancers. Here, PECAM1 is linked to lung cancer.
