EIF5A Couples Translational Control With Transcriptional Reprogramming Through Chromocenter Reorganization During Spermiogenesis

Advanced Science, EarlyView.
The translation factor Eukaryotic translation initiation factor 5A (eIF5A) is essential for male fertility in mice. It supports the translation of proteins crucial for heterochromatin organization and acrosome formation. eIF5A deficiency disrupts chromocenter integrity, increases chromatin accessibility, and causes transcriptional dysregulation ...

Chromosome mapping of dragline silk genes in the genomes of widow spiders (araneae, theridiidae) [PDF]

, 2010
With its incredible strength and toughness, spider dragline silk is widely lauded for its impressive material properties. Dragline silk is composed of two structural proteins, MaSp1 and MaSp2, which are encoded by members of the spidroin gene family ...

Development of Dimethylsulfonium Probes for Broad Profiling of Methyllysine Reader Proteins

Advanced Science, EarlyView.
Development of oligoglycine‐based dimethylsulfonium probes for unbiased crosslinking to methyllysine readers. The general probe facilitates profiling of site‐specific methyllysine readers, evaluation of selectivity and activity of reader inhibitors, and global profiling of methyllysine readers.

High-resolution mapping of heterochromatin redistribution in a Drosophila position-effect variegation model

Epigenetics & Chromatin, 2009
Background Position-effect variegation (PEV) is the stochastic transcriptional silencing of a gene positioned adjacent to heterochromatin. white-mottled X-chromosomal inversions in Drosophila are classic PEV models that show variegation of the eye color ...

Positional changes of pericentromeric heterochromatin and nucleoli in postmitotic Purkinje cells during murine cerebellum development [PDF]

, 2004
Previous studies revealed changes of pericentromeric heterochromatin arrangements in postmitotic Purkinje cells (PCs) during postnatal development in the mouse cerebellum (Manuelidis, 1985; Martou and De Boni, 2000). Here, we performed vibratome sections

Dual Aptamers‐Based SETDB1 PROTACs as Effective Anti‐Tumor Strategies for Breast Cancer

Advanced Science, EarlyView.
This study establishes dual‐aptamer PROTACs targeting SETDB1 using a SETDB1‐specific aptamer conjugated to AS1411. The designed PROTACs penetrate cells, recruit MDM2 to degrade SETDB1, and inhibit cancer cell proliferation and migration. Remarkably, they also overcome tamoxifen resistance and enhance CD8+ T cell cytotoxicity, suppressing tumor growth ...

SWI/SNF-like chromatin remodeling factor Fun30 supports point centromere function in S. cerevisiae [PDF]

, 2011
Budding yeast centromeres are sequence-defined point centromeres and are, unlike in many other organisms, not embedded in heterochromatin. Here we show that Fun30, a poorly understood SWI/SNF-like chromatin remodeling factor conserved in humans ...

Components of a Pathway Maintaining Histone Modification and Heterochromatin Protein 1 Binding at the Pericentric Heterochromatin in Mammalian Cells [PDF]

Journal of Biological Chemistry, 2004
Heterochromatin is a higher order chromatin structure that is important for transcriptional silencing, chromosome segregation, and genome stability. The establishment and maintenance of heterochromatin is regulated not only by genetic elements but also by epigenetic elements that include histone tail modification (e.g.

Respiratory Involvement in HIST1H1E‐Related Rahman Syndrome: A Case of Severe Mixed Apnea

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Rahman syndrome (HIST1H1E‐related neurodevelopmental syndrome, OMIM #617537) is a rare autosomal‐dominant condition caused by truncating variants in the C‐terminal domain of the HIST1H1E gene. It is characterized by macrocephaly, hypotonia, craniofacial anomalies, and multisystem anomalies.
