Hypothalamus Participates in Peripheral Sympathetic Hyperactivity After Acute Brain Injury by Regulating Trhr M6A Modification

open access: yesMedComm, Volume 7, Issue 10, October 2026.
In acute brain injury (TBI/ICH), sympathetic hyperactivity is driven by hypothalamic FTO upregulation. FTO demethylates Trhr, blocking m6A‐YTHDF2‐dependent degradation, which stabilizes Trhr mRNA and increases neuronal sensitivity to TRH. Restoring FTO or Trhr alleviates sympathetic hyperactivity, offering a potential target for managing autonomic ...

Clinical Epigenomics in Rare Diseases: Interpreting DNA Methylation Episignatures

open access: yesMolecular Genetics &Genomic Medicine, Volume 14, Issue 10, October 2026.
Clinical epigenomics extends rare‐disease diagnostics beyond DNA sequence by revealing the downstream regulatory consequences of genetic variation. DNA methylation episignatures provide functional evidence that can support diagnosis, refine variant interpretation, distinguish overlapping disorders, and complement genomic, and multi‐omic testing ...

DNMT1 Regulates Testosterone Synthesis in Aged Rat Leydig Cells via FTO‐Mediated HSP90AA1 m6A Levels

open access: yesAging Cell, Volume 25, Issue 10, October 2026.
During Leydig cell senescence, decreased DNMT1 triggers Fto promoter hypomethylation and upregulates FTO. Elevated FTO reduces m6A modification of Hsp90aa1, lowering HSP90AA1 to inhibit AKT signaling, facilitate apoptosis and reduce testosterone synthesis.

METTL14‐Mediated m6A Methylation Preserves Cardiomyocyte Homeostasis and Attenuates Progeria‐Associated Cardiac Remodeling

open access: yesAging Cell, Volume 25, Issue 10, October 2026.
Progerin accumulation downregulates the expression of m6A methyltransferases METTL3 and METTL14 in cardiac tissues, impairing m6A modification‐mediated regulation of target genes including Casq2, Ifna and Ifnb, leading to calcium signaling dysregulation and pro‐inflammatory activation in the aged heart.

Tumor‐Derived Exosomal piR‐hsa‐28212 Promotes Lymphatic Metastasis in Breast Cancer

open access: yesCancer Science, Volume 117, Issue 10, Page 2733-2751, October 2026.
Breast cancer–derived exosomal piR‐hsa‐28212 promotes lymphangiogenesis and lymph node metastasis by activating VEGFC/VEGFR3 signaling. It stabilizes TBX1 mRNA in lymphatic endothelial cells and METTL3 protein in tumor cells, enhancing VEGFR3 expression and VEGFC secretion.

Polyphenism Through RNA Chemical Modifications

open access: yesMolecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT Polyphenism, the capacity of a single genotype to produce discrete phenotypes in response to environmental cues, has long served as a model for understanding developmental plasticity. While classical studies have highlighted hormonal signalling and transcription‐factor‐driven gene regulatory networks that mediate these environmentally induced ...

A DRACH Observed/Expected Metric Reveals the Evolutionary Landscape of Epitranscriptomic Regulation Across Bilateria

open access: yesAnnals of the New York Academy of Sciences, Volume 1564, Issue 1, October 2026.
Epitranscriptomic marks are highly variable across life stages and tissues, complicating comparisons between species. Using m6A consensus motifs, we developed a genomic indicator reflecting transcript methylability, the DRACH o/e score, that we used to investigate epitranscriptomic features and associated functions across nine bilaterian species.
