P53-repressed miRNAs are Involved with E2F in a Feed Forward Loop Promoting Proliferation

ABSTRACT: miRNA expression profiles of WI38 primary human fibroblasts with an active or inactive p53. Cells were compared under normal untreated conditions (young and proliferating cells), after DNA damage with Doxorubicin, and upon entry into replicative senescence. Keywords: miRNA, WI-38, p53, GSE56, Senescence, Doxorubicin, Cancer, DNA-damage, fibroblasts. 6 samples of WI38 cells were analyzed on 12 Exiqon miRcurry LNA arrays in biological duplicates (2 different cell culture plates for each experimental condition). The six conditions included: 1. [Con_Young] - Primary Young WI38 cells (passage 20) with a control retroviral vector (pLXSN-NEO). Untreated. 2. [GSE_Young] -Primary Young WI38 cells (passage 20) with a retroviral vector encoding for the p53-inactivating peptide GSE56 (pLXSN-NEO-GSE
