While a hit-and-run typically leads to an arrest, in the world of epigenetic editing it turns out to be the key to evading cell cycle arrest (senescence) and promoting the transformation of a law-abiding cell into a cancerous criminal! The hypermethylation of promoters at the wrong time and wrong place is a trademark of cancer, […]

While manipulating DNA methylation has taken up most of our lifespans, the manipulation of methyl donors critical to this process may just be the key to making up for the lost time. During one-carbon metabolism, the essential amino acid methionine is metabolized into S-adenosylmethionine (SAM), a methyl donor responsible for DNA and histone methylation. Donation of […]
During early embryonic development, our genome lets down its DNA methylation defenses and becomes vulnerable to rebellious transposable elements (TEs). However, those rebel scum are quickly met with a barrage of endogenous short interfering RNAs (endosiRNAs), all before they realize even realize that “It’s A Trap!” The mechanism of this cunning tactic employed by our […]
Hi-C-based three-dimensional chromatin conformation analysis is currently living the high-life, with multiple high-impact studies recently employing this high-flying molecular technique to gain new insight into the cell cycle, fertilization, and reprogramming. Now, researchers under the high command of Boyan Bonev and Giacomo Cavalli (Université de Montpellier, France) have applied this high-class technique to understand how […]
Stress has a way of getting under our skin, where it can sink in so deep that it modifies our brain’s DNA. While it can alter DNA cytosine modifications, such as 5-methylcytosine (5mC), a new role for the N6-methyladenine (6mA) modification in stress response has now emerged. DNA 6mA has recently made the grade as […]
