UCA1 and liver cancer: In this report, our findings indicate overexpressed CUDR cooperates to overexpressed CyclinD1 or PTEN depletion to accelerate liver cancer stem cells and liver stem cells growth in vitro and in vivo. The abnormal CUDR-CyclinD1-PTEN-TERT/Myc axis leads to liver cancer stem cell and liver stem cells malignant transformation and proliferation.
