A Selfish, Poisonous Element Could Set the Evolutionary Stage for Genomic ImprintingApril 15, 2024A selfish toddler might throw a tantrum to get their way, but in worms, a “selfish” piece of DNA known as a toxin-antidote (TA) element uses something more sinister—poison. Researchers have just discovered a parent-of-origin effect with this nematode element that could be an evolutionary precursor of genomic imprinting. Led by Alejandro Burga (Institute of Molecular […]
EvoETR Epigenome Editor Helps Maintain Cholesterol Levels by Silencing Pcsk9March 25, 2024Ever wanted to cut a bad thing out of your life? Well, perhaps the secret to success doesn’t involve any cutting (of your DNA). In some people, a mutant PCSK9 gene interferes with the liver’s job to get rid of LDL, aka “bad” cholesterol. Now, researchers have developed an all-in-one “evolved engineered transcriptional repressor” (EvoETR) […]
No Epigenetic Modification is an Island: How Reader Proteins Functionally Interpret Complex Chromatin StatesMarch 25, 2024Like no man is an island and instead relies on those surrounding them, single epigenetic modifications generally do not function in solitary. Now, an absorbing new study from a synergistic epigenomics squad reports how epigenetic reader proteins functionally interpret chromatin states made up of complex combinations of disparate epigenetic modifications. A highly collaborative team guided […]
Gut Microbiota Uses the Histone Code to Make Intestinal Cells Speak Their LanguageMarch 19, 2024A growling stomach represents a clear sign that you must eat something tasty; however, sometimes, your digestive system is where the message needs to go! An exciting epigenetics study reveals that our gut microbiota employs a histone code via histone acylations to influence gene expression in intestinal cells, forcing these cells to speak their language! […]
“ATAC-see” Visualizes A World of Novel Chromatin RegulatorsMarch 11, 2024Many have seen a world of opportunities open with the release of artificial intelligence-based tools to the public; now, an all-seeing team has combined CRISPR technology with “transposase-accessible chromatin with visualization,” aka ATAC-see, to open a whole epigenome of possibilities by identifying novel chromatin regulators! The team, headed by the “visionary” Yusuke Miyanari (Kanazawa University), […]
