Expression of PC1, PC2 and 7B2 in primary colon cancer and unaffected colon. A. PC1 immunoblots in primary colon cancer in unaffected colon and in an additional primary colon cancer, note the different PC1 processing pattern between the two colon cancers. Experiments were repeated three times. B. Schematic representation of PC1 structure. C. PC2 immunoblots in primary colon cancer in unaffected colon and in an additional primary colon cancer. Note the absence of the 66 Kda band in the second primary colon cancer. Experiments were repeated three times. D. Schematic representation of PC2 structure. E. 7B2 immunoblots in primary colon cancer in unaffected colon and in an additional primary colon cancer, indicating presence of 7B2 protein only in one tumor. Experiments were repeated three times. Corresponding gels stained with Coomassie blue G250 (CS) are shown. F. Schematic representation of 7B2 structure.
