The authors unanimously wish to retract this paper because the calcium/calmodulin-dependent protein kinase 2 (CamKII) was erroneously equated with CK2 (Casein Kinase 2) throughout the paper. While all the results were valid and supported the major conclusions, the confusion between CamKII and CK2 led to misinterpretation of some data. Specifically, the speculation of a possible link between CK2 upregulation and E-cadherin hyperphosphorylation in the LSD1-hypomorphic hearts lacked experimental support.
