  • a Pearson correlation coefficients (r). A subset of SAGE data set was obtained by filtering with the criterion that each tag have at least one observation more than twice among the 10 libraries. This subset was used for calculation of r values. The generated r values were similar using different filtration criteria such as no filtration, or requiring each tag to have >5, 10, and 15 observation in at least one sample. D1 and D2 are normal pancreatic ductal epithelium, HX and H126, respectively. CL1 to CL6 are pancreatic cancer cell lines, Hs766T, Panc-1, CAPAN1, CAPAN2, PL45, and AsPc1, respectively. I1 and I2 are primary pancreatic cancer, 91-16113 and 96-6252, respectively.
