And we confirmed that the growth of the tumors formed by the human BCSCs transfected with the anti-miR-142-expressing lentivirus was significantly slower than those of the control tumors formed by the control lentivirus transfected BCSCs (Major points raised by the editors and the reviewers # 3) These data suggest that the regulation of APC and the Wnt signaling is at least one of the important pathways targeted by miR - 142 in human breast cancer cells and BCSCs.

Considering that miR - 142 is highly expressed in human BCSCs, but weakly expressed or undetectable in the stem / progenitor population of the mammary epithelial cells, our result suggest that the upregulation of miR - 142 and its enhancement of the miR - 150 expression seem to be especially relevant in the breast tumor progression in vivo.
