PANDORA-seq Opens a Pandora’s Box of sncRNAsMay 2, 2021The opening of Pandora’s box is said to have cursed the ancient Greek world with sickness, death, and innumerable other evils. Thankfully, a modern-day technique called “PANDORA-seq” brings forth new hope for removing these ancient afflictions on our epigenomes by identifying previously undetectable small non-coding RNAs (sncRNAs). A hopeful handful of researchers led by Qi […]
Meet the Escape Artists of X-Chromosome InactivationApril 22, 2021While an escape from the zoo sounds newsworthy on its own, the addition of X-chromosome inactivation (XCI) makes it irresistible for our news crew. An exciting new epigenetic effort has captured the exceptional XCI escape artists across eutherian mammals. XCI is a dosage compensation mechanism in females that results in the inactivation of one of […]
Nu.Q Capture‑MS: The New New of Liquid Biopsy Detects Histone Modifications on Circulating NucleosomesApril 20, 2021With the rapid pace of liquid biopsy assay development, it can be a challenge to keep up with the latest and greatest early cancer detection methods. Although most methods are focused on assaying the association of cell-free DNA methylation profiles with cancer, a new method homes in on circulating nucleosomes and their histone post-translational modifications (PTMs). In order […]
Removing R-loops Regulates Repression: Revealing the Role of LSD1April 19, 2021Epigenetic regulatory cascades can be complex affairs…to say the least. Thankfully, a recent chromatin effector coregulator-based study now keeps us firmly in the loop by revealing how a histone demethylase induces gene repression by triggering a regulatory cascade that removes RNA:DNA hybrid structures known as R-loops! A talented team led by Philipp Rathert (University of […]
Methylation’s Moonlighting Mysteries: DNMT3L’s Divergent Roles in Down SyndromeApril 12, 2021By daylight, DNA methyltransferase 3L (DNMT3L) takes on the modest role of a catalytically inactive but stimulatory binding partner for its more popular methyltransferase siblings (DNMT3A and DNMT3B). But, when the sun goes down, DNMT3L gives new meaning to protein moonlighting. DNMT3L is located on chromosome 21, which has made it a prime candidate for the Down syndrome […]
