Under this condition, several phenylalanine-glycine-rich Nups (FG-Nups) no longer assemble at the nuclear envelope but instead accumulate at discrete puncta in the endoplasmic reticulum (ER), which we term...

..., the contribution of intracellular membranes has been long neglected. Recently, it has become evident that various organelles play active roles in both mechanosensing and mechanotransduction. In this Review, we focus on mechanosensitive roles of the endoplasmic reticulum (ER), the functions of which are crucial...
