LncRNA DDX11-AS1 promotes breast cancer progression by targeting the miR-30c-5p/MTDH axis.

ABSTRACT: Long noncoding RNAs (lncRNAs) play a significant role in the occurrence and development of malignant tumours. However, ceRNAs, which are significantly associated with the prognosis of breast cancer (BC), need to be further investigated. Therefore, the current study aimed to investigate the effect of the lncRNA DDX11-AS1 on BC progression. Bioinformatics analysis via a public microarray revealed that DDX11-AS1 was upregulated in BC. The above findings were verified via RT‒qPCR analysis of BC tissues. Additionally, our study revealed that the expression levels of DDX11-AS1 increased with increasing pathological grade and lymph node metastasis. Furthermore, DDX11-AS1 knockdown markedly inhibited the proliferation, migration and invasion abilities of BC cells. Mechanistically, DDX11-AS1 could
