Across the same analysis, we identify DEGs specific to the patient sample, including GPX1, GSTP1, and CALML5. Similarly, DGEA reveals gene signatures specific to each cell line not expressed by the other line or patient tumor data, including TFF3, MDK, and KRT19 isolated to BT474 and S100A9, LCN2, and HLA-B specific to HCC1954. The gene discussed is S100A9; the disease is neoplasm.
