DYRK1B and ovarian carcinoma: Previous studies also demonstrate Dyrk1A, the closest isoform of Mirk may phosphorylate FoxO1 and promote nuclear output (20,21), thus there is a possibility that it is the subcellular localization and phosphorylation of FoxO factors but not the total protein level that is altered in Mirk/Dyrk1B siRNA-treated ovarian cancer cells.
