RNA-binding proteins (RBPs) and miRNAs are capable of controlling processes in normal development and cancer.
Both of them could determine RNA transcripts fate from synthesis to decay.
One such RBP, Dead end (Dnd1), is essential for regulating germ-cell viability and suppresses the germ-cell tumors development, yet how it exerts its functions in breast cancer has remained unresolved.
The level of Dnd1 was detected in 21 cancerous tissues paired with neighboring normal tissues by qRT-PCR.
We further annotated TCGA (The Cancer Genome Atlas) mRNA expression profiles and found that the expression of Dnd1 and Bim is positively correlated ( p = 0 .
04 ).
Patients with higher Dnd1 expression level had longer overall survival ( p = 0 .
0014 ) by KM Plotter tool.
Dnd1 knockdown in MCF-7 cells decreased Bim expression levels and inhibited apoptosis.
While knockdown of Dnd1 promoted the decay of Bim mRNA 3′UTR, the stability of Bim-5′UTR was not affected.
In addition, mutation of miR-221-binding site in Bim-3′UTR canceled the effect of Dnd1 on Bim mRNA.
Knockdown of Dnd1 in MCF-7 cells confirmed that Dnd1 antagonized miR-221-inhibitory effects on Bim expression.
Overall, our findings indicate that Dnd1 facilitates apoptosis by increasing the expression of Bim via its competitive combining with miR-221 in Bim-3′UTR.
The new function of Dnd1 may contribute to a vital role in breast cancer development.
