FEBS letters, 588(17), 3000-3007 (2014-06-15)
EZH2 is a key component of the polycomb PRC2 complex and functions as a histone H3 Lys27 (H3K27) trimethyltransferase. Here we show that EZH2 is down-regulated in human non-small cell lung cancer and low EZH2 expression predicts poor survival. Further

Thyroid hormones (TH) and receptors (TRs) may play an important role in the pathophysiology of acute cerebral ischemia. In the present study, we sought to determine whether serum triodothyronine (T3)/thyroxine (T4) and brain TRs (TRα1, TRβ1) might change after experimental
Koshiki Mino et al.
Bioscience, biotechnology, and biochemistry, 78(6), 1010-1017 (2014-07-19)
Tissue factor pathway inhibitor-2 (TFPI-2) is a major inhibitor of extracellular matrix degradation. Decreases in TFPI-2 contribute to malignant tumor cell production, and TFPI-2 is a presumed tumor suppressor. TFPI-2 gene transcription is regulated by two epigenetic mechanisms: DNA methylation
Signaling to chromatin through histone modifications.

Nan Li et al.
Inflammation, 37(4), 1191-1199 (2014-02-18)
Acute kidney injury (AKI) is a severe complication of sepsis, which largely contributes to the high mortality rate of sepsis. Honokiol, a natural product isolated from Magnolia officinalis (Houpo), has been shown to exhibit anti-inflammatory and antioxidant properties. Here, we
Sarah L Larsen et al.
BMC cancer, 15, 239-239 (2015-04-18)
Resistance to antiestrogen therapy is a major clinical challenge in the treatment of estrogen receptor α (ER)-positive breast cancer. The aim of the study was to explore the growth promoting pathways of antiestrogen resistant breast cancer cells to identify biomarkers
Chaoran Li et al.
Proceedings of the National Academy of Sciences of the United States of America, 111(27), E2807-E2816 (2014-06-25)
Forkhead box P3(+) (Foxp3(+)) regulatory T cells (Tregs) are crucial for peripheral tolerance. During inflammation, steady Foxp3 expression in Tregs is essential for maintaining their lineage identity and suppressive function. However, the molecular machinery governing Tregs' resilience to inflammation-induced Foxp3
Ahrom Ham et al.
American journal of physiology. Renal physiology, 307(9), F1052-F1062 (2014-08-29)
Peptidyl arginine deiminase (PAD)4 is a nuclear enzyme that catalyzes the posttranslational conversion of arginine residues to citrulline. Posttranslational protein citrullination has been implicated in several inflammatory autoimmune diseases, including rheumatoid arthritis, colitis, and multiple sclerosis. Here, we tested the
Inhibition of different histone acetyltransferases (HATs) uncovers transcription-dependent and-independent acetylation-mediated mechanisms in memory formation.

Silvina V Sonzogni et al.
Molecular and cellular biochemistry, 398(1-2), 63-72 (2014-09-11)
DNA is continuously exposed to damaging agents that can lead to changes in the genetic information with adverse consequences. Nonetheless, eukaryotic cells have mechanisms such as the DNA damage response (DDR) to prevent genomic instability. The DNA of eukaryotic cells
The program for processing newly synthesized histones H3.1 and H4.

Chromium is a potent human mutagen and carcinogen. The capability of chromium to cause cancers has been known for more than a century, and numerous epidemiological studies have been performed to determine its carcinogenicity. In the post-genome era, cancer has

Oncogene, 33(45), 5262-5273 (2013-11-05)
Inhibition of type 1 insulin-like growth factor receptor (IGF-1R) enhances tumor cell sensitivity to ionizing radiation. It is not clear how this effect is mediated, nor whether this approach can be applied effectively in the clinic. We previously showed that
Toshiaki Iba et al.
Thrombosis research, 134(1), 169-173 (2014-05-13)
The activation of coagulation is recognized as a universal event in severe sepsis. Both antithrombin and thrombomodulin play pivotal roles as suppressors of coagulation. Since the levels of both anticoagulants decrease significantly, we hypothesized that a combination therapy would be

Nucleic acids research, 42(12), 7642-7653 (2014-06-01)
Chromatin structure and its alteration play critical roles in the regulation of transcription. However, the transcriptional silencing mechanism with regard to the chromatin structure at an unstimulated state of the interferon (IFN)-stimulated gene (ISG) remains unclear. Here we investigated the

Emerin is a conserved membrane component of nuclear lamina structure. Here, we report an advance in understanding the molecular basis of emerin function: intermolecular emerin-emerin association. There were two modes: one mediated by association of residues 170-220 in one emerin

Acetylation of histones changes the efficiency of the transcription processes and thus contributes to the formation of long-term memory (LTM). In our comparative study, we used two inhibitors to characterize the contribution of different histone acetyl transferases (HATs) to appetitive

Posterior capsule opacification (PCO) after cataract surgery is due in part to proliferation of the adhering lens epithelial cells and transdifferentiation into mesenchymal cells. The histone deacetylase (HDAC) inhibitors, trichostatin A (TSA) and vorinostat (suberoylanilidehydroxamic acid [SAHA]) are known to

Histones post-translational modifications (PTMs) are crucial components of diverse processes that modulate chromatin. Among the histones PTMs, the histones phosphorylation appears such crucial since it plays a significant role into DNA repair structure, transcription and chromatin compaction during cell division
