Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

open access: yesAdvanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Heterochromatin revisited [PDF]

open access: yesNature Reviews Genetics, 2007
The formation of heterochromatin, which requires methylation of histone H3 at lysine 9 and the subsequent recruitment of chromodomain proteins such as heterochromatin protein HP1, serves as a model for the role of histone modifications and chromatin assembly in epigenetic control of the genome.

Heterochromatin is late

open access: yesThe Journal of Cell Biology, 2005
In 1953—the year that Watson and Crick published those findings “of considerable biological interest”—Howard and Pelc (1953) showed that DNA synthesis occurred in a discrete phase of the cell cycle. They had labeled DNA with radioactive phosphate.

Selfish centromeres, selfless heterochromatin

open access: yesCell, 2021
Centromeres are specialized regions on chromosomes recruiting a set of proteins required for faithful chromosome segregation. Differences in centromere strength can potentially bias chromosome segregation toward one of the daughter cells during division. Kumon et al. propose a new model of evolutionary impact on the balance of centromere strength.

Toward a molecular understanding of yeast silent chromatin : roles for H4K16 acetylation and the Sir3 C-terminus [PDF]

open access: yes, 2012
Discrete regions of the eukaryotic genome assume a heritable chromatin structure that is refractory to gene expression. In budding yeast, silent chromatin is characterized by the loading of the Silent Information Regulatory (Sir) proteins (Sir2, Sir3 and

Early-replicating heterochromatin [PDF]

open access: yesGenes & Development, 2003
Euchromatin, which has an open structure and is frequently transcribed, tends to replicate in early S phase. Heterochromatin, which is more condensed and rarely transcribed, usually replicates in late S phase. Here, we report significant deviation from this correlation in the fission yeast,Schizosaccharomyces pombe.

The Interplay between the Gut and Ketogenic Diets in Health and Disease

open access: yesAdvanced Science, EarlyView.
This review synthesizes current knowledge on the interaction between ketogenic diets and the gut, covering gut physiology, intestinal immunity, and the gut microbiome. It explores innovative methods for tailoring the diet to maximize benefits while reducing side effects. Emphasis is placed on gut‐mediated mechanisms as a critical interface between diet
