To predict ceRNA networks specific to colorectal adenocarcinoma (COAD), our investigation has unveiled interactions between long non-coding RNAs (lncRNAs), including ZFAS1, SOX21-AS1, SNHG11, SNHG16, and SNHG1, with hsa-miR-7-5p. The gene discussed is SOX21; the disease is colorectal adenocarcinoma.
