SAGE analysis of Sulf-2 expression in human breast cancer. Data pertinent to Sulf-2 were mined from a published SAGE analysis of human breasts [23]. Sulf-2 tags were enumerated from 4 normal breast tissue libraries, 7 DCIS libraries, and 12 IDC libraries. The total number of SAGE tags in the analysis was 1.75 million. The incidences of Sulf-2 tags in the different tissue libraries were 0.0018% (normal), 0.012% (DCIS), and 0.032% (IDC). The graph shows the mean number of Sulf-2 tags per 100,000 total tags from the libraries for each class of tissue. The error bars indicate SEM. The probabilities provided in the figure and text are based on a t-test comparison in the source study [23].
