Environmental Enrichment Reverses Histone Methylation Changes in the Aged Hippocampus and Restores Age-Related Memory Deficits

Biology, 2015
A decline in long-term memory (LTM) formation is a common feature of the normal aging process, which corresponds with abnormal expression of memory-related genes in the aged hippocampus. Epigenetic modulation of chromatin structure is required for proper

Critical roles of protein methyltransferases and demethylases in the regulation of embryonic stem cell fate

Epigenetics, 2017
Accumulating evidence has recently shown that protein methyltransferases and demethylases are crucial regulators in either maintaining pluripotent states or inducing differentiation of embryonic stem cells. These enzymes control pluripotent signatures by

Targeting Viral Methyltransferases: An Approach to Antiviral Treatment for ssRNA Viruses

Viruses, 2022
Methyltransferase enzymes have been associated with different processes within cells and viruses. Specifically, within viruses, methyltransferases are used to form the 5′cap-0 structure for optimal evasion of the host innate immune system. In this paper,

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Networking and Specificity-Changing DNA Methyltransferases in Helicobacter pylori

Frontiers in Microbiology, 2020
Epigenetic DNA base methylation plays important roles in gene expression regulation. We here describe a gene expression regulation network consisting of many DNA methyltransferases each frequently changing its target sequence-specificity.

Targets of histone H3 lysine 9 methyltransferases

Frontiers in Cell and Developmental Biology, 2022
Histone H3 lysine 9 di- and trimethylation are well-established marks of constitutively silenced heterochromatin domains found at repetitive DNA elements including pericentromeres, telomeres, and transposons. Loss of heterochromatin at these sites causes

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

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.

rRNA methyltransferases and their role in resistance to antibiotics [PDF]

Journal of Medical Biochemistry, 2010
Methyltransferases (MTases), a large protein superfamily, commonly use S-adenosyl-L-methionine (SAM) as the methyl group donor. SAM-dependant MTases methylate both nucleic acids (DNA, RNA) and proteins, and thus modulate their activity, function and ...
