Moreover, many transcriptional factors, including snail and ZEB, have crucial roles in EMT‐induced processes.6 The ZEB family (ZEB1 and ZEB2) is closely related to the EMT‐related markers of malignant tumors.7 However, the regulatory role of lncRNA‐ZEB2‐AS1 in ZEB2 expression in breast cancer remains unreported. Here, PTGDR is linked to breast cancer.
