PFKFB4 Deubiquitination by USP10 Enhances Fumarate Metabolism to Orchestrate the KDM1A/Rad51 Axis and Confer Radioresistance in Lung Cancer

Advanced Science, EarlyView.
USP10 binds to and stabilizes PFKFB4, enhancing glycolytic ATP production, which activates the urea cycle and elevates fumarate. This inhibits histone demethylase KDM1A, leading to increased H3K4me1 enrichment at the Rad51 promoter and direct activation of Rad51 transcription, which confers lung cancer radioresistance. The PFKFB4 inhibitor 5MPN targets

Dynamic changes in genome-wide histone H3 lysine 4 methylation patterns in response to dehydration stress in Arabidopsis thaliana

BMC Plant Biology, 2010
Background The molecular mechanisms of genome reprogramming during transcriptional responses to stress are associated with specific chromatin modifications. Available data, however, describe histone modifications only at individual plant genes induced by

Exposure to p40 in Early Life Prevents Intestinal Inflammation in Adulthood Through Inducing a Long-Lasting Epigenetic Imprint on TGFβSummary

Cellular and Molecular Gastroenterology and Hepatology, 2021
Background & Aims: Colonization by gut microbiota in early life confers beneficial effects on immunity throughout the host’s lifespan. We sought to elucidate the mechanisms whereby neonatal supplementation with p40, a probiotic functional factor ...

A Personalized Haplotype‐Resolved Near‐Gapless Genome Framework for Somatic Variant Discovery in Hepatocellular Carcinoma

Advanced Science, EarlyView.
A patient‐specific, haplotype‐resolved genome framework improves detection and interpretation of somatic variants in hepatocellular carcinoma. Using multi‐platform sequencing, the personalized assembly resolves complex regions including centromeres and MHC/HLA loci, enhances structural variant discovery, and links regulatory alterations to allele ...

Human biomarker navigator

iMeta, EarlyView.
The Human Biomarker Navigator integrates the disease continuum, biomarker dynamics, cross‐organ biomarker networks, biomarker classification, and technology‐driven paradigms. It maps how biomarkers link multi‐system physiology and pathology across the nervous, respiratory, endocrine, circulatory, immune, digestive, urinary, reproductive, and ...

The Functional Role and Molecular Characterization of the Therapeutic Target CLDN6 in Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Background The tight junction protein CLDN6 has been identified as a cancer‐associated cell surface marker that is rarely expressed in healthy tissues. In testicular germ cell tumors (GCT), CLDN6 is particularly detectable in seminomas, embryonal carcinomas, and choriocarcinomas.

KPNA2 Drives Immunosuppression in Ovarian Cancer via CCL2/CCR2‐Dependent MDSC Recruitment

Cancer Science, EarlyView.
KPNA2 drives intratumoral MDSC accumulation and immunosuppression in ovarian cancer via the NF‐κB/CCL2/CCR2 axis. Mechanistically, KPNA2 facilitates NF‐κB/p65 nuclear translocation and induces CCL2 transcription, recruiting MDSCs to establish an immunosuppressive microenvironment.

Heterogeneous enhancer states orchestrate β cell responses to metabolic stress

Nature Communications
Obesity-induced β cell dysfunction contributes to the onset of type 2 diabetes. Nevertheless, elucidating epigenetic mechanisms underlying islet dysfunction at single cell level remains challenging.

Histone Lysine Demethylases KDM5B and KDM5C Modulate Genome Activation and Stability in Porcine Embryos

Frontiers in Cell and Developmental Biology, 2020
The lysine demethylases KDM5B and KDM5C are highly, but transiently, expressed in porcine embryos around the genome activation stage. Attenuation of KDM5B and KDM5C mRNA hampered embryo development to the blastocyst stage in fertilized ...

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics

The FEBS Journal, EarlyView.
This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...
