WebThe lamin-B1 reduction was associated with nuclear deformations, represented by an increased incidence of invaginated nuclei and loss of nuclear circularity in senescent astrocytes in vitro and in the aging human hippocampus. We also found differences in lamin-B1 levels and astrocyte nuclear morphology between the granular cell layer and ... WebNov 15, 2024 · We previously demonstrated that loss of lamin B1 is a novel marker to identify senescent cells. Here, we demonstrate that loss of lamin B1 facilitates the detection and quantification of senescent cells upon UV-exposure in vitro and upon chronic UV-exposure and skin regeneration in vivo. Taken together, this marker enables the study of ...
Loss of lamin A function increases chromatin dynamics in the
WebNov 15, 2024 · Lamin C has six unique C-terminal residues, whereas lamin A has an extended tail domain that undergoes four post-translational modification steps to achieve its final mature length of 646 or 647 residues, in humans and mice respectively [ 33 ]. Until recently lamin A and lamin C were assumed to be mostly functionally redundant. WebWhen ectopically expressed in somatic cells, lamin B3 causes severe deformation of nuclei which adopt a hook-like configuration. Accordingly, it was proposed that lamin B3 provides the germ line cells with a more flexible nuclear periphery that facilitates spermatogenesis-specific nuclear reorganization events. alla sparade
