<h4>Background</h4>The study was designed to elucidate the association and functional roles of miR-26b-5p and c-MYC binding protein (MYCBP) in triple-negative breast cancer (TNBC).<h4>Method</h4>Luciferase reporter assay was used to confirm the relationship between miR-26b-5p and MYCBP in TNBC cells. Here, MYCBP is linked to triple-negative breast carcinoma.
