WFDC21P and gastric cancer: 1E). Therefore, qPCR was used to detect WFDC21P expression in 10 pairs of GC tissues and corresponding paracancerous tissues. The qPCR result showed that WFDC21P was upregulated in GC tissues than that in adjacent normal tissues (Fig. 1F). To further confirm this result, we screen the expression of WFDC21P in GC cell lines (AGS, MKN-45, SGC-7901, and N87) and normal gastric cell lines (GES-1). qPCR result indicated that WFDC21P expression was also upregulated in GC cell lines compare to normal gastric cell lines (Fig. 1G).
