There is a strange phenomenon in epigenetics where cells use energy to cycle chemical DNA modifications.Nobody knows what such oscillations are good for. We show that chromatin-mediated interactions lead to complex genomic patterns in DNA methylation oscillations.@prxlife.bsky.social bit.ly/4tBS1LJ

Spatiotemporal Patterns of Active Epigenetic Turnover

Chromatin-mediated coupling between cycles of DNA methylation and demethylation can lead to the emergence of phase-locked domains --- regions of locally synchronized turnover activity whose coarsening...

New preprint: How do cells measure time? In human development, pluripotent epiblast cells pause for about two weeks before differentiating into more specialised cell types. We show that this timing is controlled by a transcriptional clock that works like an hourglass. www.biorxiv.org/content/10.1...

A transcriptional clock of the human pluripotency transition

Developmental timing differs strikingly between mammals. All embryonic and some placental lineages emerge from the pluripotent epiblast in a temporally defined sequence, lasting about two weeks in the...

Highly Specific Miniaturized Fluorescent Monoacylglycerol Lipase Probes Enable Translational Research

Monoacylglycerol lipase (MAGL) is the pivotal catabolic enzyme responsible for signal termination in the endocannabinoid system. Inhibition of MAGL offers unique advantages over the direct activation of cannabinoid receptors in treating cancer, metabolic disorders, and inflammatory diseases. Although specific fluorescent molecular imaging probes are commonly used for the real-time analysis of the localization and distribution of drug targets in cells, they are almost invariably composed of a linker connecting the pharmacophore with a large fluorophore. In this study, we have developed miniaturized fluorescent probes targeting MAGL by incorporating a highly fluorescent boron-dipyrromethene (BODIPY) moiety into the inhibitor structure that interacts with the MAGL active site. These miniaturized fluorescent probes exhibit favorable drug-like properties such as high solubility and permeability, picomolar potency for MAGL across various species, and high cell selectivity and specificity. A range of translational investigations were conducted, including cell-free fluorescence polarization assays, fluorescence-activated cell sorting analysis, and confocal fluorescence microscopy of live cancer cells, live primary neurons, and human-induced pluripotent stem cell-derived brain organoids. Furthermore, the application of red-shifted analogs or 18F positron emission labeling illustrated the significant versatility and adaptability of the fluorescent ligands in various experimental contexts.

Why Bax detection in >1400 publications might be flawed? The culprit: a poorly validated antibody that went unchecked for years … until recently !!!

Just stumbled on this 💎 of a paper at my end-of-the-year review of the #apoptosis #Bax #Bcl2 literature (i.e., trying to get that last paper out). Can't stress enough how glad I am that this gets reported and has a venue in a high profile journal! 🔬🧪👍👍👍 @natureportfolio.bsky.social
