Long noncoding RNAs (lncRNAs) play an important role in the regulation of gene expression and are involved in several pathological responses. However, many important lncRNAs in breast cancer have not been identified and their expression levels and functions in breast cancer remain unknown. In this study, the lncRNA apoptosis-associated transcript in bladder cancer (AATBC) was found to be significantly highly expressed in breast cancer patients. In vitro and in vivo experiments indicated that AATBC promoted breast cancer metastasis. Further studies revealed that AATBC activated the YAP1/Hippo signaling pathway through the AATBC-YBX1-MST1 axis. This is also an important supplement to the composition of the YAP1/Hippo signaling pathway. The model of "AATBC-YAP1" may bring a new dawn to the treatment of breast cancer.
