Functional mutations identified in patients with androgen insensitivity syndrome, in the formin and actin nucleator DAAM2, uncover signal-regulated nuclear actin assembly at a steroid hormone receptor necessary for transcription.

Kirkland et al. identify conserved age-dependent nuclear remodeling in Drosophila cardiomyocytes, dependent on declining Lamin C. They show that Lamin C loss induces reversible heart dysfunction by repressing myogenic transcription factors.

Strain maps of cardiomyocyte nuclei during contraction indicate that, by integrating environmental mechanical cues, the nuclei of cardiomyocytes stabilize the fate of cells through the reorganization of epigenetically marked chromatin.

We found that aging is accompanied by a reduction in cardiomyocyte nuclear size and increased stiffness, dependent on loss of A-type lamins. Mechanistically, age-dependent nuclear remodeling represses expression of cardiogenic transcription factors that are required for heart contractility. Preserving lamin or transcription factors delays cardiac decline.

The oligomerization of scaffold attachment factor A through its binding to chromatin-associated RNAs regulates the structure of interphase chromosomes.

LINC complex structure and nucleoskeleton organization are key factors in the transmission of mechanical stress to the nucleus.

Two studies reveal roles for B-type lamins in organogenesis and cell proliferation.
