Reference title
Reciprocal regulation of Hsa-miR-1 and long noncoding RNA MALAT1 promotes triple-negative breast cancer development
Experimental verification
qPCR, Western blot, RIP, Luciferase reporter assay etc.
Functional description
We reported that MALAT1 was upregulated in triple-negative breast cancer (TNBC) tissues. Knockdown of MALAT1 inhibited proliferation, motility, and increased apoptosis in vitro. In vivo study indicated that knockdown of MALAT1 inhibited tumor growth and metastasis. Patients with high MALAT1 expression had poorer overall survival time than those with low MALAT1 expression. In addition, our findings demonstrate a reciprocal negative control relationship between MALAT1 and miR-1: downregulation of MALAT1 increased expression of microRNA-1 (miR-1), while overexpression of miR-1 decreased MALAT1 expression. Slug was identified as a direct target of miR-1.
