NEAT1 and breast cancer: Eventually, we proposed the lncRNA‐miRNA‐mRNA pathway: NEAT1/MALAT1/XIST‐‐hsa‐mir‐101‐3p‐‐DLGAP5 and the circRNA‐miRNA‐mRNA pathway: PKD‐‐hsa‐mir‐101‐3p‐‐DLGAP5 are potential RNA regulatory pathways of BC, which regulated the occurrence, development, metastasis, chemosensitivity resistance of BC.
