Advanced Science, Volume 13, Issue 7, 3 February 2026.In this study maize chloroplastic malate dehydrogenase7 (ZmMDH7), is identified as a Rhizoctonia solani resistance gene in maize. ZmMDH7 is regulated by transcription factor ZmWRKY44 via pathogens challenge to elevate mitochondrial ROS and SA signaling pathway.

Neurogenesis and the Epigenetic Landscape: Role of Histone Modifications and Chromatin Remodeling
Brain and Behavior, Volume 16, Issue 2, February 2026.Histone methylation and acetylation modulate gene expression by inducing chromatin condensation or relaxation, which in turn regulates transcriptional activity and impacts neurogenesis. ABSTRACT Aims The purpose of this review is to examine how epigenetic regulation particularly chromatin modification and histone methylation controls gene expression ...

Clinical and Translational Medicine, Volume 16, Issue 2, February 2026.(1) Core Process: Persistent antigen, from TDLNs to TME, drives Tpex → Tex‐int → Tex‐term differentiation. (2) Multiomics Regulation: This fate transition is orchestrated by a co‐ordinated, multi‐layered molecular network. (3) Functional Outcome: Dysregulated signalling and surging co‐inhibitory receptors lock in proliferative arrest and functional ...

Dynamic expression of lamin B1 during adult neurogenesis in the vertebrate brain
Developmental Dynamics, Volume 255, Issue 2, Page 187-208, February 2026.Abstract Background In mammals, specific brain regions such as the dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles harbor adult neural stem/progenitor cells (ANSPCs) that give rise to new neurons and contribute to structural and functional brain plasticity.

A Novel Human Cellular System for Studying Normal Aging and for Anti‐Aging Discovery
Aging Cell, Volume 25, Issue 2, February 2026.This study introduces a human cellular aging model using placental trophoblasts (hTSC‐STBs) that mimics key aging features like senescence and genomic instability. It aligns with human tissue aging and responds to anti‐aging treatments, offering a scalable platform to screen potential therapies and bridge lab findings to clinical applications ...

, 2018 The condensed structure of heterochromatin differs significantly from euchromatin and DNA bound in heterochromatin is generally not transcriptionally active. Transcriptional silencing allows the control of gene expression and affords a novel mechanism of defense against genomic parasites.
