NECTIN2 and gastric cancer: Subsequently, we conducted an assessment of the expression levels of several established immune-related genes, namely CSF1R, CD274, TGFB1, TGFBR1, IL10, VTCN1, NECTIN2, PDCD1LG2, LGALS9, BTLA, and KDR, in order to demonstrate the differential expression patterns observed between low- and high-risk gastric cancer cases (Figure 8C).
