MiR‐155 targets TP53INP1 to regulate liver cancer stem cell acquisition and self‐renewal

Abstract excerpt

In liver cancer, miR-155 up-regulation can regulate cancer-cell invasion. However, whether miR-155 expression is associated with liver cancer stem cells (CSCs) remains unknown. Here, we show that miR-155 expression is up-regulated in tumor spheres. Knock-down of miR-155 resulted in suppression of tumor sphere formation, through a decrease in the proportion of CD90(+) and CD133(+) CSCs and in the expression of...
