One of the first interactions that emerged in breast cancer tissue compared to normal tissue was the interaction between RMND5A, EIF5B, SUN2, KLHL18, KDSR, RPSK6KA3 ceRNAs and the miR-338-5p, miR-223-3p, miR-129-5p, miR-642a-5p, miR-3619-5p, and miR-382-5p miRNAs. The gene discussed is RMND5A; the disease is breast carcinoma.
