The expression level of NTN1 was increased in GC specimens. A. NTN1 mRNA expression level in 97 paired GC tissues and adjacent normal tissues were investigated by qRT-PCR. B. Representative results of upregulation of NTN1 protein in GC specimens with or without NI by immunohistochemistry. N indicated nerve. Original magnification, 200×; Scale bar=100μm. C. Quantification of the percentage of cells demonstrating the presence of immunoreactivity for NTN1 (positive staining). *p < 0.05, **p < 0.01, ***p < 0.001.
