The human RNAs upregulated in gastric cancer were INHBA, SPP1, THY1, SERPINH1, CXCL1, FSCN1, COL1A1, SPARC, COL1A2, PTGS2 (COX2), BBC3, ICAM1, TNFSF9, MYC, SULF1, SLC2A1, COL3A1, PCNA, and TYMS, while the downregulated RNAs were CDH1 (E-cadherin), CLDN18, CHGA (chromogranin), PTEN, SDC1 (CD138) and GAST (gastrin). This evidence concerns the gene SULF1 and gastric cancer.
