These results show that a lamin B1-containing nucleoskeleton is required to maintain RNA synthesis and that ongoing synthesis is a fundamental determinant of global nuclear architecture in mammalian cells. ‡ Author for correspondence...

In myoblasts transfected with the mutant lamins, this complex was disrupted. These data suggest that remodelling of the nucleoskeleton...
