CCL27 and neoplasm: If we only used PSDA information (marked by red color), cell lines such as UACC812 and ZR751 were predicted to be ILC with PSDA = 100%, disregarding the fact that these cell lines’ expression patterns were highly dissimilar to the averaged expression pattern (center) of ILC tumor cohort on SDA projection (large DSSDA = 2.991 and 2.970 to ILC, respectively) (S3 Table).
