Allelic Variation in Maize Malate Dehydrogenase 7 Shapes Promoter Methylation and Banded Leaf and Sheath Blight Resistance

Advanced Science, EarlyView.
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.

Nortriptyline Inhibits Lysosomal Exocytosis‐Mediated SASP During Gastric Cancer Progression via Targeting HOXA1‐PITX2 Phase Separation

Advanced Science, EarlyView.
This study identifies that HOXA1 facilitates transcriptional activity of PITX2 in liquid condensates, resulting in up‐regulation of MCOLN1 and RAB3A followed by lysosomal exocytosis of LGALS1 and IGFBP7 from senescent cells, thus activating AKT signaling and EMT.

ATRX: From Chromatin Remodeling to Disease. [PDF]

Genesis
ABSTRACT Chromatin remodeling proteins are evolutionarily conserved factors involved in a wide range of biological processes. In this review, we describe ATRX, a chromatin remodeling protein belonging to the SWI/SNF2 family. Its association with different protein complexes, and its roles in embryonic development, sexual differentiation, as well as ...

H3K9me3-heterochromatin loss at protein-coding genes enables developmental lineage specification

Science, 2019
Reversing chromatin dynamics for development Compacted chromatin regions, marked by trimethylation of histone H3 at position lysine 9 (H3K9me3), occur at highly repeated DNA sequences, helping to suppress recombination and gene expression.

NUSAP1 Recruits DAXX to Suppress HIF‐Driven Triple‐Negative Breast Cancer Progression

Advanced Science, EarlyView.
A double‐negative feedback loop is identified in TNBC where NUSAP1 bridges HIF and DAXX via its microtubule‐associated domain (MAD) to recruit SETDB1, repressing HIF transcriptional activity by depositing the H3K9me3 repressive mark on HIF target genes, while HIF itself suppresses NUSAP1.

HP1a-mediated heterochromatin formation inhibits high dietary sugar-induced tumor progression

Cell Death and Disease, 2021
High dietary sugar (HDS) is a modern dietary concern that involves excessive consumption of carbohydrates and added sugars, and increases the risk of metabolic disorders and associated cancers.

SETDB2 Mitigates Podocyte Dysfunction in Diabetic Kidney Disease Through Epigenetic Silencing of SMAD3

Advanced Science, EarlyView.
SETDB2 epigenetically represses Smad3 transcription by increasing H3K9me3 enrichment at its promoter, thereby mitigating podocyte dysfunction in DKD. The transcription factor TCF21 binds directly to the Setdb2 promoter and enhances its expression in podocytes. Abstract Podocyte dysfunction represents both an early pathological hallmark and a key driver

Advancing the Tendinopathy Triad: Comment on “Tendinopathy: The Interplay Between Mechanical Stress, Inflammation, and Vascularity”

Advanced Science, EarlyView.
Abstract Building upon the integrative framework of tendinopathy proposed by Gehwolf et al.—which elegantly connects mechanical stress, inflammation, and vascularity—this commentary extends the discussion by introducing novel mechanistic insights and future research directions that move beyond the established triad. A paradigm shift is proposed ...
