The Brain Cell Census: A Deeper Epigenomic Understanding of the Mammalian MainframeNovember 13, 2023If you have epigenetics on the brain like us, concentrate your mammalian mainframe on the recently published marvels on the brain’s epigenome from the NIH’s Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative – Cell Census Network (BICCN). Recent work brought together under the guise of the Brain Cell Census now reports on the examination […]
Keeping COVID-19 in the Family – SARS-CoV-2 Infection Reprograms Immune Responses Through Epigenetic MemorySeptember 24, 2023We try to keep exciting research findings in our epigenetic “family,” and a recent article now reports that our stem and immune cells are not so different when it comes to their epigenetic memory of SARS-CoV-2 infection! A new study now describes how SARS-CoV-2-mediated epigenetic reprogramming in hematopoietic stem and progenitor cells (HSPCs) severely impacts […]
“Dynamite” Study Uses TNT To Destroy Epigenetic Memories in Human iPSCsSeptember 11, 2023While lingering memories can represent unwelcome guests, destroying them with the power of dynamite may seem like overkill! However, a volatile new study now describes TNT or transient-naïve-treatment as a simple means of ridding human induced pluripotent stem cells (hiPSC) of their epigenetic memories and improving their therapeutic potential. An explosive epigenetic team headed by […]
Altered Chromatin Accessibility Shows Why Aging Stem Cells Don’t Know if They’re Coming or Going!August 13, 2023Once young and carefree, the passing years creep up on us all and bring so many responsibilities and places to be that we don’t know whether we are coming or going! A busy new study shows that the chromatin accessibility and gene expression alterations that occur during aging impact neural stem cells (NSCs) in much […]
Going Green! – How Histone Recycling Promotes the Preservation of Pristine Epigenetic LandscapesMarch 6, 2023The climate crisis and our need to produce less waste have made recycling an everyday concept; however, whether histone proteins “go green” during DNA replication has remained somewhat in doubt. The epigenetic environment becomes disrupted during DNA replication and must be restored to maintain genome regulation and cell identity; now, two high-efficiency epigenetic studies provide […]
Now In Print! – New Technologies Leave their Mark on Imprinting Control RegionsJune 19, 2022Genomic imprinting typically lets our parents leave their mark on our genomes; however, new technological advances are now allowing us to leave our mark on imprinting! The first of our epigenetic exposés that went into print reports on how multiple modalities uncovered complex epigenetic crosstalk that regulates allele-specific gene expression at potential imprinting control regions […]
NANOG’s Prion-like Behavior Builds Bridges to PluripotencyMay 11, 2022In both the literal and figurative sense, building bridges can really get you places! Knowing this, genome engineers and epigenetic architects recently created a blueprint demonstrating how a pioneer transcription factor – NANOG – uses prion-like behavior to form gel-like protein condensates that create interstrand DNA “bridges” to reorganize chromatin and clear a rapid path […]
EpiDamID Contains a Flood of Histone Modification Findings from Single Cells!May 2, 2022Lately, we’ve been faced with a veritable torrent of awesome single-cell epigenomics methods; thankfully, the development of a new technique – EpiDamID – promises to easily contain the floods of findings regarding histone modification and gene expression patterns coming from single cells! Previously, a talented team from the lab of Jop Kind (Hubrecht Institute, Utrecht, […]
APOE Tips Heterochromatin Balance Towards Stem Cell Senescence and AgingApril 11, 2022Like a healthy balance between work and play can enhance our day-to-day lives, a new study suggests that stem cells require a healthy epigenetic balance between silent and active chromatin domains to support their ongoing normal functions. More specifically, researchers headed by the well-balanced quartet of Moshi Song, Weiqi Zhang, Jing Qu, and Guang-Hui Liu […]
Epigenetic “Baby-steps” Repress Germline Genome-defense During DevelopmentFebruary 4, 2022Much like a set of helping hands can guide, support, and protect a toddler taking their first steps, the guiding force of epigenetics during embryonic development ensures genome stability and supports healthy development by regulating the expression of key genes. Such genes include DNA methylation-sensitive “germline genome-defense” genes, which undergo DNA demethylation and become expressed […]
