METTL5 Enables Immune Evasion of Liver Cancer via Chemokine mRNA Translation Regulation

Advanced Science, EarlyView.
METTL5 reshapes the tumor immune microenvironment through ribosome 18S rRNA m6A modification to regulate the translation of chemokine mRNA. Targeting METTL5‐mediated immunosuppression unleashes anti‐tumor immunity and improves the efficacy of anti‐PD‐1 therapy.

Hepatocyte Mettl3 Deficiency Drives Primary Sclerosing Cholangitis and Liver Fibrosis via Cholangiocyte‐Macrophage Crosstalk

Advanced Science, EarlyView.
Schematic illustration demonstrating that hepatic Mettl3 depletion significantly elevates the secretion of Mif and Csf1. This elevation facilitates Trem2+ macrophage infiltration and triggers cholangiocyte remodeling through the Spp1‐Cd44 interaction, resulting in spontaneous PSC development in vivo.

Unraveling the Morphological and Functional Maturation Mechanisms Underlying Human Neural Development Using iPSCs‐Derived Neuronal Model

Advanced Science, EarlyView.
Using human induced pluripotent stem cells (hiPSCs)‐derived neuronal model, Tian and colleagues reveal that voltage‐gated calcium channels Cav1.2 and Cav1.3, and their mediated calcium ion influx, are essential for early morphogenesis of human neuronal development, while ECEL1 underlies human neuronal functional developmental maturation through CALM3 ...

Epigenetic regulation of Epichloë festucae secondary metabolite biosynthesis and symbiotic interaction with Lolium perenne : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Genetics at Massey University, Palmerston North, New Zealand [PDF]

, 2017
Histone methylation is one of several epigenetic layers for transcriptional regulation. Most studies on the importance of this histone modification in regulating fungal secondary metabolite gene expression and pathogenicity have focussed on the role of

WDR5‐H3K4me3 Epigenetic Axis Promotes TRMT6‐Dependent tRNA M1A Modification to Facilitate Triple‐Negative Breast Cancer Progression by Suppressing Ferroptosis

Advanced Science, EarlyView.
Upregulated TRMT6 forms aberrant hypermethylation of a specific tRNA pool and serves as a predictor of poor prognosis in TNBC. This m1A modification in tRNAs enhances translation of FTH1 and FTL, reducing the pool of bioavailable Fe2⁺. Reduced Fe2+ availability impairs RSL3‐induced lipid peroxidation and tumor progression.

Methylation status of Dnmt1 promoter depends on poly(ADP-ribosy)lation [PDF]

, 2007
Research is focused on CpG islands and on the mechanism that poly(ADP-ribosyl)ation uses to defend the unmethylated state of these important DNA sequences which are located in the promoter regions of the housekeeping genes having a role of transcription ...

Discovery of a Novel DNMT1 Inhibitor with Improved Efficacy in Treating β‐Thalassemia

Advanced Science, EarlyView.
Context of Research: β‐thalassemia affects millions worldwide. DNMT inhibitors are effective HbF‐inducers that benefit patients with β‐thalassemia. Existing DNMT inhibitors are not approved for β‐thalassemia treatment due to dose‐limiting toxicity.What We Find: DMT207 traps DNMT1 into helix‐kinked inactive conformation and enhances its interaction with
