Subsequently, the significantly high expression of S100A2 in tumor cells was confirmed by qRT-PCR in pancreatic normal cell line (HPNE) and pancreatic cancer cell lines (AsPC-1, BxPC-3, Capan-1, CFPAC-1, MIA PaCa-2, PATU 8988, PANC-1, SW1990, and T3M4) (Figure 5B). The gene discussed is S100A2; the disease is neoplasm.
