Local euchromatin enrichment in lamina-associated domains anticipates their repositioning in the adipogenic lineage

open access: yesGenome Biology, 2022
Background Interactions of chromatin with the nuclear lamina via lamina-associated domains (LADs) confer structural stability to the genome. The dynamics of positioning of LADs during differentiation, and how LADs impinge on developmental gene expression,

Role of histone deacetylases in gene regulation at nuclear lamina.

open access: yesPLoS ONE, 2012
Theoretical models suggest that gene silencing at the nuclear periphery may involve "closing" of chromatin by transcriptional repressors, such as histone deacetylases (HDACs). Here we provide experimental evidence confirming these predictions.

Non-canonical Drosophila X chromosome dosage compensation and repressive topologically associated domains

open access: yesEpigenetics & Chromatin, 2018
Background In animals with XY sex chromosomes, X-linked genes from a single X chromosome in males are imbalanced relative to autosomal genes. To minimize the impact of genic imbalance in male Drosophila, there is a dosage compensation complex (MSL) that ...

Barrier-to-autointegration factor proteome reveals chromatin-regulatory partners. [PDF]

open access: yesPLoS ONE, 2009
Nuclear lamin filaments and associated proteins form a nucleoskeletal ("lamina") network required for transcription, replication, chromatin organization and epigenetic regulation in metazoans.

Optic nerve cavitations in glaucoma suspect and glaucoma patients

open access: yesAmerican Journal of Ophthalmology Case Reports, 2022
Purpose: Glaucoma is associated with structural changes of the optic nerve head such as deformation, lamina cribosa defects, prelaminar schisis, and peripapillary retinal schisis. We describe optic nerve cavitations that were detected by routine spectral

Optic disc microvasculature dropout in primary open-angle glaucoma measured with optical coherence tomography angiography. [PDF]

open access: yesPLoS ONE, 2018
PURPOSE:To evaluate microvasculature dropout in the optic disc (Mvd-D) using optical coherence tomography angiography (OCTA) and investigate factors associated with Mvd-D in primary open-angle glaucoma (POAG) eyes.

Nuclear Lamin B1 Interactions With Chromatin During the Circadian Cycle Are Uncoupled From Periodic Gene Expression

open access: yesFrontiers in Genetics, 2019
Many mammalian genes exhibit circadian expression patterns concordant with periodic binding of transcription factors, chromatin modifications, and chromosomal interactions. Here we investigate whether chromatin periodically associates with nuclear lamins.

The nuclear envelope protein, LAP1B, is a novel protein phosphatase 1 substrate. [PDF]

open access: yesPLoS ONE, 2013
Protein phosphatase 1 (PP1) binding proteins are quintessential regulators, determining substrate specificity and defining subcellular localization and activity of the latter.

Nuclear lamin phosphorylation: an emerging role in gene regulation and pathogenesis of laminopathies

open access: yesNucleus, 2020
Decades of studies have established that nuclear lamin polymers form the nuclear lamina, a protein meshwork that supports the nuclear envelope structure and tethers heterochromatin to the nuclear periphery.

Role of lamins in 3D genome organization and global gene expression

open access: yesNucleus, 2019
Genome-wide mapping of lamin-B1-genome interactions has shown that gene-poor and transcriptionally inactive genomic regions are associated with the nuclear lamina.
