Epitranscriptomic tRNA Study Finally Reveals the “Y” of Aggressive Colon TumorsAugust 25, 2020Away with you Holmes, begone Poirot, and bye-bye Nancy Drew, because a terrific team of epigenetic detectives has solved an epitranscriptomic cold case to reveal the “Y” of aggressive colon tumors by linking CpG island promoter DNA hypermethylation of a key epitranscriptomic modifier and a transfer RNA (tRNA) modification to tumorigenesis. Epitranscriptomics includes the modification […]
Cell free DNA MeDIP-seq is a Molecular Methylation Magnet for Machine Learning Cancer DetectionAugust 7, 2020Finding the cell free DNA (cfDNA) that most cell-types release into blood plasma is always a challenging task, but certain cancers release so little that it takes looking for a needle in a haystack to the next level. Methods for sorting the “hay” have often come up short, but two new studies successfully developed a […]
Cutting Through the Smog of Mitochondrial DNA Methylation after Prenatal Pollution ExposureAugust 7, 2020While everyone loves hearing about a scientific controversy, clearing the air can also provide a sense of satisfaction. So, sit back and take a breath of the fresh air that an environmentally conscious team brings to the controversy surrounding mitochondrial (mt)DNA methylation through their examination of prenatal exposure to environmental stressors such as air pollution […]
Common DNA Methylation Aging Profiles Convert Dog to Human Years Better Than EverJuly 20, 2020They say you can’t teach an old dog new tricks, but it turns out you can use new epigenomic tricks to tell you how old a dog is. The heuristic that to get a dogs age in human years, you multiply by seven is a little simplistic, and due for an update using epigenomic insights. […]
Filling in the Blanks: DNA Methylation-Dependent Glycosylation of Chromatin Modifiers Represses TranscriptionJuly 7, 2020You might think our portrait of the marks that make up the epigenetic landscape is nearing completion, but a new feature is now filling in some of the blank space behind a key regulatory mechanism. It has been long known that DNA methylation represses transcription via the recruitment of methylation-dependent repressive factors. The components of […]
