Among these DEGs, 27 genes were downregulated; they are CEP68, ADAMTS1, PLAGL1, ABCA6, NPR1, ENPP2, LDB2, LIFR, PDE2A, CXCL12, SPTBN1, SEMA3G, SRPX, FAM107A, CAV1, FMO2, ACACB, EDNRB, TGFBR3, SDPR, NDRG2, ZBTB16, AKR1C1, FHL1, ABCA8, CD36, and LYVE1. On the other hand, 9 genes were elevated in breast cancer; they are COL10A1, COL11A1, INHBA, COMP, SULF1, MMP11, BGN, FN1, and HN1. This evidence concerns the gene PDE2A and breast cancer.
