HS3ST2 and colorectal carcinoma: In this study, a systematic bioinformatics analysis identified two miRNAs (hsa-miR-99a and hsa-miR-100) and one gene (heparan sulfate-glucosamine 3-sulfotransferase 2 [HS3ST2]), through which a novel mRNA–miRNA regulatory network in lymph node metastasis of CRC was established.
