TFF2 expression was detected in BxPC-3, AsPc-1, Capan-1, CFPAC, HPac, Capan-1, SNU-213, Capan-2, Panc 03.27, and Panc 02.13, implying that TFF2 selected from genome-wide expression profiles is mainly expressed by tumor cells in the utilized tissue specimens. This evidence concerns the gene TFF2 and neoplasm.
