A 2026 PLOS One computational study linked Trichostatin A to 949 predicted targets and 8 machine-learning-selected Alzheimer’s disease core genes, but 100 ns molecular dynamics simulations suggested the compound did not stably bind those candidate proteins.1 That makes the result more useful as an epigenetic network hypothesis than as evidence for a near-term Alzheimer’s drug. …
Nucleosomes may be far less uniform inside living chromatin than the textbook picture suggests. In a 2026 Nature study, a single-molecule method called IDLI found that more than 85% of sampled nucleosomes in mouse embryonic stem cells showed intranucleosomal DNA accessibility, meaning the DNA wrap was partly open or distorted rather than perfectly sealed around …
One-pronuclear biparental zygotes may be less biologically normal than they look. In a 2026 Nature mouse study, forcing maternal and paternal genomes into 1 enlarged pronucleus disrupted early embryonic epigenetic marks, while the usual 2-pronuclear state created a cytoplasmic competition that helped preserve developmental potential.1 Research Highlights The 2026 zygote study asks why mammalian zygotes …
A 2026 prospective birth-cohort study in southern China linked mean cord-blood lead of 15.30 μg/L to lower infant neurodevelopmental scores across all 5 Ages and Stages Questionnaire domains, even though only 1.13% of samples exceeded 50 μg/L.1 A second finding was mechanistic: part of the lead-development association statistically ran through FAM50B/PTCHD3 DNA methylation, an epigenetic …
A 2026 Singapore birth-cohort preprint found a conditional childhood-anxiety signal: the cord-blood DNA methylation component predicted less age-13 anxiety only in boys in the low DMN-limbic trajectory group from ages 4.5 to 10.5 years. The paper is useful for mapping developmental risk biology, but it is not a screening test and it does not show …
A 2026 Nature Communications study found that Mecp2 overexpression deregulated approximately 5,000 genes in mouse neural progenitor cells but only approximately 500 mostly small-change genes in mature neurons, with the same progenitor-vs-neuron split reproduced in human iPSC-derived cells.1 For Rett syndrome gene therapy, that is the useful calibration: extra MeCP2 is most dangerous when it …
The opioid crisis, particularly in North America, has spotlighted oxycodone as a central figure due to its significant role in addiction and overdose deaths. A recent review analyzed the genomic and epigenetic mechanisms behind oxycodone’s effects compared to other opioids, shedding light on its unique impact on addiction pathways. Highlights: Oxycodone, a semi-synthetic opioid derived …
