These target genes were crossed with mRNAs that are downregulated by more than fivefold in cervical cancer from The Cancer Genome Atlas (TCGA) database, and 8 target genes were finally obtained (OGN, SCN7A, PGR, PTGER3, FGF7, ADAMTS5, LMO3 and ANK2). The gene discussed is PTGER3; the disease is cervical carcinoma.
