H3K27me3 and the PRC1-H2AK119ub pathway cooperatively maintain heterochromatin and transcriptional silencing after the loss of H3K9 methylation

Epigenetics & Chromatin
Background Heterochromatin is a fundamental component of eukaryotic chromosome architecture, crucial for genome stability and cell type-specific gene regulation.

Functional Crosstalk between Lysine Methyltransferases on Histone Substrates: The Case of G9A/GLP and Polycomb Repressive Complex 2 [PDF]

, 2015
Significance: Methylation of histone H3 on lysine 9 and 27 (H3K9 and H3K27) are two epigenetic modifications that have been linked to several crucial biological processes, among which are transcriptional silencing and cell differentiation.

Research progress on the role of inflammatory mediators in the pathogenesis of epilepsy

Ibrain, Volume 11, Issue 1, Page 44-58, Spring 2025.
In the central nervous system, activated immune cells lead to the overproduction of inflammatory mediators through the corresponding signal pathway. Under the stimulation of inflammatory factors, neuroinflammation ultimately occurs. Overexpression of inflammatory mediators and activated immunocytes plays an important role in the emergence and ...

A family case of fertile human 45,X,psu dic(15;Y) males [PDF]

, 2006
We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal

Somatic cell reprogramming for Parkinson's disease treatment

Ibrain, Volume 11, Issue 1, Page 59-73, Spring 2025.
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option

MTHFR promotes heterochromatin maintenance

Biochemical and Biophysical Research Communications, 2014
Methylenetetrahydrofolate reductase (MTHFR), a key enzyme in the folate cycle, catalyzes the reduction of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate, a co-substrate for homocysteine remethylation to methionine. Methionine serves as the precursor of the active methyl donor S-adenosylmethionine, which provides methyl groups for many ...

The Effects of Angiotensin Receptor Neprilysin Inhibitor on Endoplasmic Reticulum Stress in Doxorubicin‐Mediated Cardiomyopathy‐Associated Heart Failure Model in Rats

Journal of Applied Toxicology, EarlyView.
ABSTRACT One of the most serious complications associated with the use of the chemotherapeutic agent doxorubicin (DOX) is cardiomyopathy. Although cardioprotective drugs such as angiotensin receptor‐neprilysin inhibitors (ARNI) are used to prevent cardiomyopathy in DOX patients, no studies have reported the relationship between ARNI and endoplasmic ...

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 ...

Cytological features of penaut genome [PDF]

, 2017
The genus Arachis is composed of 82 species (Krapovickas and Gregory 1994; Valls and Simpson 2005; Valls et al 2013; Santana and Valls 2015) mainly distributed within a large region of South America, which extends from the eastern foothills of the Andes ...
