Nature Communications, 2023 Obesity-induced adipose tissue dysfunction can cause low-grade inflammation and downstream obesity comorbidities. Although preadipocytes may contribute to this pro-inflammatory environment, the underlying mechanisms are unclear.

Open Chromatin and Hypertranscription in Embryonic Stem Cells [PDF]
Cell Stem Cell, 2008 In this issue of Cell Stem Cell, Efroni et al. (2008) use tiling microarrays to reveal genome-wide hypertranscription in mouse embryonic stem cells (ESCs), including expression of normally silent, noncoding regions. Hypertranscription may reflect the unusual "open" structure of ESC chromatin.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Keys to Open Chromatin for Transcription Activation: FACT and Asf1 [PDF]
Molecular Cell, 2009 In this issue of Molecular Cell, Takahata et al. (2009) dissect the mechanisms preceding transcription initiation, revealing a wave of nucleosome eviction, which spreads from distant cis-regulatory elements to promoters and which requires the activity of histone chaperones, FACT and Asf1.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

, 2010 Chromatin is the template of all processes involved in DNA metabolism in the eukaryotic cell. Accordingly, chromatin is a dynamic structure which changes in its composition and posttranslational modification correlating with the functional state of a ...

Ultrastructural analysis of chromatin in meiosis I plus II of rye (Secale cereale L.) [PDF]
, 2004 Scanning electron microscopy (SEM) proves to be an appropriate technique for imaging chromatin organization in meiosis I and II of rye (Secale cereale) down to a resolution of a few nanometers.

Enclosing Chromatin: Reassembly of the Nucleus after Open Mitosis [PDF]
Cell, 2013 During mitosis in vertebrate cells, the nuclear envelope undergoes extensive structural reorganization, starting with the retraction of nuclear membranes into the ER at mitotic onset and ending with the re-enclosure of chromatin by ER-derived membranes during mitotic exit. Here, we review our current understanding of postmitotic nuclear assembly.

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Global chromatin architecture reflects pluripotency and lineage commitment in the early mouse embryo. [PDF]
PLoS ONE, 2010 An open chromatin architecture devoid of compact chromatin is thought to be associated with pluripotency in embryonic stem cells. Establishing this distinct epigenetic state may also be required for somatic cell reprogramming.
