Two different conditional mouse models were used in order to determine the role of the transactivating NF-κB subunit RelA/p65 in liver regeneration after partial hepatectomy (PHx). RelA/p65 was either genetically inactivated specifically in hepatocytes (RelaF/FAlbCre-) or in hepatocytes and in non-parenchymal cells (RelaF/FMxCre-mice). Surprisingly, both RelaF/FAlbCre- and RelaF/FMxCre-mice showed effective liver regeneration without increased liver damage after PHx. In RelaF/FAlbCre-mice an accelerated cell-cycle entry was found after PHx. However, this had no significant effect on liver mass regeneration. Thus, the transactivating NF-κB subunit RelA/p65 is not essential for successful liver regeneration after PHx.
