Gadd45a is an RNA binding protein and is localized in nuclear speckles.

PLoS ONE, 2011
BackgroundThe Gadd45 proteins play important roles in growth control, maintenance of genomic stability, DNA repair, and apoptosis. Recently, Gadd45 proteins have also been implicated in epigenetic gene regulation by promoting active DNA demethylation ...

Development and in vitro evaluation of chitosan nanoparticles encapsulating Phoenix dactylifera L. (Ajwah) seed extract with supporting in silico molecular docking analysis

Food Biomacromolecules, EarlyView.
Abstract This research describes the engineering of chitosan nanoparticles (CS NPs) via ionic gelation to encapsulate Ajwah seed extract (ASE), repurposing a plant waste product for its documented antioxidant and anticancer potential. Physicochemical analysis confirmed the formation of stable nanoparticles with hydrodynamic diameters between 152.3 and ...

Azacytidine and decitabine induce gene-specific and non-random DNA demethylation in human cancer cell lines.

PLoS ONE, 2011
The DNA methyltransferase inhibitors azacytidine and decitabine represent archetypal drugs for epigenetic cancer therapy. To characterize the demethylating activity of azacytidine and decitabine we treated colon cancer and leukemic cells with both drugs ...

5-Methylcytosine and 5-hydroxymethylcytosine spatiotemporal profiles in the mouse zygote.

PLoS ONE, 2012
BackgroundIn the mouse zygote, DNA methylation patterns are heavily modified, and differ between the maternal and paternal pronucleus. Demethylation of the paternal genome has been described as an active and replication-independent process, although the ...

Epigenetic Regulation in the Pathogenesis of Renal Inflammation: Insights and Therapeutic Potentials

iNew Medicine, EarlyView.
ABSTRACT Renal inflammation is a common pathological process in various kidney diseases, often initiated by factors such as toxins, ischemia, or autoimmune reactions. This inflammatory response can result in structural damage and a rapid decline in renal function.

Active DNA demethylation by DNA repair: Facts and uncertainties

DNA Repair, 2016
Pathways that control and modulate DNA methylation patterning in mammalian cells were poorly understood for a long time, although their importance in establishing and maintaining cell type-specific gene expression was well recognized. The discovery of proteins capable of converting 5-methylcytosine (5mC) to putative substrates for DNA repair introduced

Insulin Resistance: An Update on Biochemical and Pathophysiological Mechanisms and Impact on Various Diseases

iNew Medicine, EarlyView.
ABSTRACT Insulin resistance is the biological phenomenon in which the human body's normal response to the metabolic hormone insulin is compromised. Insulin is a regulator of most of the essential metabolic steps in the body that control energy homoeostasis, so dysregulation leads to multiple diverse human diseases including, most prominently, Type 2 ...

Vascular Calcification: Mechanisms, Models, and Therapies

iNew Medicine, EarlyView.
ABSTRACT Vascular calcification represents an active multifactorial process that mirrors several key features of skeletal bone mineralization. Clinically, it is characterized by diminished arterial compliance and increased arterial wall stiffness, both of which serve as independent predictors of significant adverse cardiovascular events.

Epigenetic regulation of Epichloë festucae secondary metabolite biosynthesis and symbiotic interaction with Lolium perenne : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Genetics at Massey University, Palmerston North, New Zealand [PDF]

, 2017
Histone methylation is one of several epigenetic layers for transcriptional regulation. Most studies on the importance of this histone modification in regulating fungal secondary metabolite gene expression and pathogenicity have focussed on the role of

Sensitivity towards DMI fungicides and haplotypic diversity of their CYP51 target in the Mycosphaerella graminicola population of Flanders [PDF]

, 2014
Septoria leaf blotch, caused by the fungus Mycosphaerella graminicola, is the most important wheat disease in Northwestern Europe, and is currently controlled by fungicide applications.
