Identification of Methylated Genes Associated with Aggressive Clinicopathological Features in Mantle Cell Lymphoma

open access: yes, 2011
Background: Mantle cell lymphoma (MCL) is genetically characterized by the t(11;14)(q13;q32) translocation and a high number of secondary chromosomal alterations. The contribution of DNA methylation to MCL lymphomagenesis is not well known.

Metabolic Imbalance Triggers Adaptive Remodeling to Accelerate Diploidization in Murine Haploid Embryonic Stem Cells

open access: yesAdvanced Science, EarlyView.
In this article, Shuai and colleagues demonstrate that metabolic remodeling drives self‐diploidization in murine haploid ESCs (haESCs). Mitochondrial dysfunction and imbalanced pyruvate metabolism underlie this process. Genome‐wide screening using haESCs identifies key mitochondrial quality‐control related genes, enabling a metabolism‐based medium that

Cigarette Smoke‐Induced Alveolar Macrophage Senescence via GEM/SIRT3‐Mediated Mitochondrial Dysfunction

open access: yesAdvanced Science, EarlyView.
Cigarette smoke accelerates the aging of immune cells in the lung. By combining human single‐cell sequencing, cell culture, and mouse models, the authors show that the protein GEM drives mitochondrial damage and senescence in alveolar macrophages by suppressing SIRT3.

Epigenetic Silencing of RFX7 Defines a Transcriptional Axis Linking Lactate Metabolism to Immune Checkpoint Therapy in Glioblastoma

open access: yesAdvanced Science, EarlyView.
Glioblastoma (GBM) exhibits RFX7 silencing via promoter hypermethylation, which downregulates PIK3IP1 to activate PI3K/AKT signaling, increase lactate accumulation, and enhance histone H4K12 lactylation. This lactylation upregulates PD‐L1/CSF1 expression and drives the immunosuppressive microenvironment formation.

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

open access: yesAdvanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

Multi‐Omics Insights Into the Mechanisms of Early Muscle Fiber Difference and Transformation Between Lean‐Type and Chinese Indigenous Pigs

open access: yesAdvanced Science, EarlyView.
Multi‐omics analyses uncover breed‐specific cis‐regulatory landscapes and higher‐order chromatin architectural differences that underlie early postnatal muscle fiber divergence in pigs. A super‐enhancer upstream of PPP3CB recruits MEF2C to activate PPP3CB transcription, while the PPP3CB–MEF2C positive feedback loop promotes oxidative muscle fiber ...

Introgressed Variation in TaMYB7‐A1 Drives Graded Dormancy and Climate‐Adaptive Pre‐Harvest Sprouting Resistance in Wheat

open access: yesAdvanced Science, EarlyView.
TaMYB7‐A1 directly activates TaABI5 to enhance ABA signaling and regulate ABA‐GA homeostasis, enforcing seed dormancy. Its superior allele, derived from wild einkorn introgression, harbors a MITE insertion that elevates expression and two amino acid substitutions that enhance transcriptional activity, collectively generating graded PHS resistance for ...

Palmitic Acid Promotes Antiviral Innate Immunity via ZDHHC20‐Mediated CMPK2 Palmitoylation

open access: yesAdvanced Science, EarlyView.
Metabolites have important functions in innate immune activation and regulation. Wang et al. uncover metabolic regulation of antiviral immunity through CMPK2 palmitoylation, which regulates CMPK2 mitochondrial localization and is promoted by ZDHHC20 but reversed by PPT1, inhibition of which antagonizes viral infection in mice.

ACLY‐Driven Metabolic Reprogramming Promotes Histone Acetylation and Inflammation‐Associated Fibrosis in Chronic Kidney Disease

open access: yesAdvanced Science, EarlyView.
This study reveals a citrate–ACLY–H3K27ac metabolic–epigenetic axis driving inflammatory gene activation and kidney fibrosis, highlighting ACLY inhibition as a potential therapeutic strategy for chronic kidney disease (CKD). ABSTRACT The mechanisms by which metabolic stress drives epigenetic dysregulation and fibrosis in chronic kidney disease (CKD ...
