WNT signaling pathway that is an important regulator of the stem cell properties in mammary tissues, we tested the ability of miR - 142 to regulate the organoid formation of BCSCs.

In this study, we report that miR - 142 efficiently recruits the APC mRNA to an RNA - induced silencing complex, activates the canonical
WNT signaling pathway in an APC - suppression dependent manner, and activates the expression of miR - 150.
Because each miRNA has multiple target genes, we speculate that the presence of many other target genes with higher affinity to the miR -150-containing RISC will perturb the ability of miR - 150 to regulate the APC mRNA and that miR - 150 has much weaker effect, if any, on
the WNT signaling pathway in vivo.
We note that our new results show that miR - 142 upregulates the expression of miR - 150 when miR - 142 is highly expressed and / or
the Wnt signaling pathway is strongly stimulated in mammary epithelial cells.
1) The results of the inhibition of miR -142-3p in the human breast cancer xenograft cells and
