As opposed to solid tumor tissues (P/M) with only two significantly upregulated genes (ACKR2, CYP8B1) between miliary and non-miliary (9 versus 11 samples, respectively), tumor cells from ascites (A/S, 16 miliary versus 6 non-miliary samples, respectively) revealed 215 significantly differentially expressed genes, 138 of them down- and 77 upregulated in miliary (Table 2). The gene discussed is ACKR2; the disease is neoplasm.
