PTX3 and breast cancer: 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).
