... tumors and cell lines, miR-17- 5p and miR-20a are induced in a manner that depends on cyclin D1 and repress the expression of cyclin D1. Hence, miR-17-5p ⁄ 20a and cyclin D1 form a feedback loop and ... transcription factors E2F and Myc but, in turn, miR-17-92 downregulates the expression of E2F and Myc [52]. In tumor progression, the tran- scription repressors ZEB1 and SIP1...
