We identified 46 cDEGs, including 18 up-regulated (CD24, BGN, GALNT10, CXCL10, NREP, COL11A1, CTTN, JPT1, IDH2, EPPK1, FN1, INHBA, SDC1, FAM83D, COL10A1, TRIM59, PLK1, UBE2C) and 28 down-regulated (NFIA, EIF1, SPTBN1, RBP7, PDK4, TACC1, CXCL2, PALMD, ADIRF, TFPI, AKR1C1, ACACB, NOVA1, ABCA5, PCOLCE2, SYNM, CD36, PLAGL1, NR3C1, SLIT3, ARRB1, PTX3, MGLL, ADAMTS1, LIFR, RASD1, SOCS2, FAM107A) as the BC-causing genes from three microarrays and one scRNA-seq count data and visualized them by the Venn diagram (see Figure 2). Here, CXCL2 is linked to breast cancer.
