A p53-Responsive miRNA Network Promotes Cancer Cell Quiescence

Abstract excerpt

Abstract Cancer cells in quiescence (G0 phase) are resistant to death, and re-entry of quiescent cancer cells into the cell-cycle plays an important role in cancer recurrence. Here we show that two p53-responsive miRNAs utilize distinct but complementary mechanisms to promote cancer cell quiescence by facilitating stabilization of p27. Purified quiescent B16 mouse melanoma cells expressed higher levels of...
