Tīmeklis2013. gada 31. okt. · The lamina is composed of the intermediate filament proteins Lamin A/C, Lamin B1, and Lamin B2, which form separate but interconnected networks. ... Here, we show that PRR14 localizes to the nuclear lamina in interphase and functions to tether peripheral HP1-H3K9me3-marked heterochromatin to the nuclear … Tīmeklis2024. gada 4. marts · Overall, there is a progressively increased colocalization between nuclear lamina and chromatin regions located at the nuclear periphery, as shown in Fig. 7G. In addition, the nanodomain size from chromatin and nuclear lamina is progressively reduced in precancerous and cancer cells, and their sizes were …

TīmeklisThe nuclear lamina (NL) interacts with hundreds of large genomic regions termed lamina associated domains (LADs). The dynamics of these interactions and the relation to epigenetic modifications are poorly understood. We visualized the fate of LADs in single cells using a “molecular contact memory” approach. In each nucleus, only … Tīmeklis2024. gada 25. okt. · Here we demonstrate that Proline Rich 14 (PRR14) protein specifically organizes H3K9me3-modified heterochromatin at the nuclear lamina. …
Tīmeklis2024. gada 6. jūn. · As expected, ChIP-seq analysis demonstrated reduced enrichment in long-range H3K9me3 occupancy (H3K9me3 mountains) in constitutive heterochromatin regions, especially at the LAD regions and the LAD located repetitive elements, indicative of a reduced association between heterochromatin and nuclear … Tīmeklis2024. gada 14. maijs · Superresolution microscopy revealed undulations and wrinkling of the NE/lamina in stretched cells, along with decreased H3K9me3 at the nuclear periphery (Figures 3 B and 3C). Interestingly, however, total Lamin levels were unaltered ( Figures S3 C and S3D).
Tīmeklis2012. gada 31. aug. · Because pericentric H3K9me3 is reduced to H3K9me1 in Suv39h dn cells, it is unlikely that H3K9me3 constitutes the sole heterochromatin anchor. Despite its weak affinity toward H3K9me1 ( Fischle et al., 2003 ), HP1α might still contribute to attachment of heterochromatin to the nuclear lamina, particularly … Tīmeklis2024. gada 1. febr. · Juxtaposed to the interior (nucleoplasmic) face of the INM is the nuclear lamina (NL), a ∼10–30 nm thick meshwork of lamin intermediate filaments and their associated proteins ...
