Wee1 Is A Biological Target Of The Mir-17-92 Cluster In Leukemia, Sonia Susan Olikara
Master's Theses
MicroRNAs are noncoding RNAs that bind to the 3' untranslated region of their mRNA targets, which causes downregulation of target gene expression. Previous studies have shown that the miR-17-92 cluster, which encodes six miRNAs, is overexpressed in leukemias arising from chromosomal translocations of the Mixed Lineage Leukemia (MLL) gene. In the present study, prediction algorithms identified WEE1, a kinase that inhibits cell cycle progression, as a possible target of five of the six miRNAs. Through luciferase reporter assays, we found that miR-17, miR-20a, and miR-18a specifically target nucleotides 465 to 487 of the 3' UTR of WEE1, while miR-19a and …
