RT-PCR analysis of 19 pancreatic carcinoma cell lines and 2 colorectal carcinoma cell lines (SW480 and RKO). Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) serves as a RNA control. All cancer cell lines but Hs766T and RKO strongly express S100A4. Treatment of Hs766T with 5-aza-2-deoxycytidine restores the expression of S100A4.
