Cover Story: A human telomere consists of a tract of tandemly repeated short DNA sequences d(TTAGGG) with a single-stranded overhang that can form G-quadruplex (G4) structures. In this study, the effects of N6-methyladenine (m6dA) modification on the thermal stability of four distinct telomeric G4 structures were investigated. Circular dichroism melting analysis demonstrated that the telomeric G4 structures formed in K+ were stabilized by m6dA modifications. Moreover, the thermal stability of the telomeric G4 structure formed in Na+ changed depending on the position of m6dA modification. These results contribute to the understanding of telomere biology, which can lead to applications in anti-cancer drug development. View this paper

N6-methyladenine modification (m6dA) has recently been identified in eukaryote genomic DNA. The methylation destabilizes the duplex structure when the adenine forms a Watson–Crick base pair, whereas the methylation on a terminal unpaired adenine stab...

Adipocytes play an essential role in maintaining energy homeostasis in mammals. The primary function of white adipose tissue (WAT) is to store energy; for brown adipose tissue (BAT), primary function is to release fats in the form of heat. Dysfunctio...

Arginine methylation is an essential post-translational modification (PTM) deposited by protein arginine methyltransferases (PRMTs) and recognized by Tudor domain-containing proteins. Of the nine mammalian PRMTs, PRMT5 is the primary enzyme responsib...

The epidermis is the outer part of the skin that protects the organism from dehydration and shields from external insults. Epidermal cells, called keratinocytes, undergo a series of morphological and metabolic changes that allow them to establish the...
