Transgenerational Epigenetic Inheritance of Horizontally-transferred Memories Goes ViralOctober 4, 2021While research into the transgenerational epigenetic inheritance went viral long ago, a new “social media” platform powered by horizontal transfer has taken “going viral” a bit too literally. In their retweetable new article, researchers from the lab of Coleen T. Murphy (Princeton University, New Jersey) now demonstrate that virus-like particles (VLPs) support horizontally-transferred memories and […]
scSPRITE Adds a Twist to Single-cell Genome OrganizationSeptember 27, 2021Are your single-cell chromosome conformation capture experiments looking a little flat? Is your Hi-C data missing that “pop”? Well, don´t fret; a new study serves up a refreshing twist on a popular technique – scSPRITE – that will put some fizz back into your single-cell genome organization research! While bulk profiling provides an averaged read-out […]
CRISPR-EChO Amplifies the Sound of Silent ChromatinSeptember 6, 2021Hello heterochromatin, my old friend; CRISPR has come to edit you again; And echo in the sound of silence. As reported in a resounding new study, CRISPR-EChO comes at you from the lab Stanley Qi (Stanford University, California) and amplifies the sounds of silent chromatin. Following on from avant-garde studies describing CRISPR-GO and CasDrop, which […]
Supersizing Crops by Demethylating RNA – A New Way to End World Hunger?August 23, 2021While supersizing meals has helped to expand the waistlines of many a human “couch potato,” a seriously sumptuous new study has established that RNA demethylation induced via the expression of the human RNA demethylase FTO in potatoes results in a supersizing that could help end world hunger. The transformation of exogenous and endogenous genes has […]
Single-cell Multi-omics of the Immune Response to VaccinationJuly 26, 2021A recent viral study revealed that SARS-CoV-2 infection alters chromatin accessibility in our all-important immune cells to facilitate immune memory – but does the same apply to vaccination? To answer this somewhat flu-mmoxing question, a flu-id force of epigeneticists led by Bali Pulendran (Stanford University, California) utilized single-cell multi-omics to explore the effects of influenza […]
Single-Cell ATAC-seq Shows that Chromatin Remodeling Allows Immune Cells to Remember COVID-19June 24, 2021While few will remember the last eighteen months with any great fondness, the memory of our immune cells represents a critical facet controlling long-lasting responses induced by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection and exposure to vaccines. In an unforgettable study, researchers led by Liang Chen, Mark M. Davis, and Pengyuan Yang now demonstrate […]
New Single-cell CRISPR Screens “ATAC” Chromatin AccessibilityJune 6, 2021Have you been struggling to agree on a plan of action for your recent epigenetic experiments? Have you been fighting over just what strategy to use to decipher how genetic alterations affect the epigenetic landscape? While we should all follow John and Yoko’s example and try to give peace a chance, you sometimes need to […]
CRISPRon, CRISPRoff… Two New Tools to Earn You the Black Belt in Hit-and-Run Epigenetic EditingMay 17, 2021Power, accuracy, and stability are the three tenets of hit-and-run epigenetic editing that every aspiring black belt must learn to master. To aid our quest, masters from the dojos of Luke Gilbert (University of California, San Francisco) and Jonathan Weissman (Massachusetts Institute of Technology) have come forth with not only new mantra but also a new set […]
Timing is Everything – Even for Maintaining the Global Epigenetic State of Human Cells!May 17, 2021They say that timing is everything – from the perfect golf shot to the most cutting joke – and now, a well-timed study establishes that DNA replication timing is everything when it comes to maintaining the global epigenetic state of human cells! Studies had previously described a link between the temporal order of DNA replication […]
scCUT&Tag: The Cutting Edge of Single-Cell Histone Modification ProfilingMay 11, 2021While we’re usually fans of shortcuts that make our lives easier, this exciting combination of accessible methods to profile single-cell chromatin modifications has our attention, no matter how you slice it. Chromatin profiling using cleavage under targets and tagmentation (CUT&Tag) allows you to investigate histone post-translational modifications and transcription factor occupancy, particularly when limited by […]
