Excessive DNA Double‐Strand Breaks–Associated 3D Genome Reorganization Contributes to Neural Tube Defects with Folate Deficiency

open access: yesAdvanced Science, EarlyView.
Neural tube defects (NTDs) are among the most common congenital malformations. However, the underlying etiology and mechanism remain elusive. Here, the role of DNA double‐strand breaks (DSBs) in 3D genome organization within the NTDs with folate deficiency is reported.

Genome‐Wide by Lifetime Environment Interaction Studies of Brain Imaging Phenotypes

open access: yesAdvanced Science, EarlyView.
This study explores genome‐wide by lifetime environment interactions on brain imaging phenotypes. Gene‐environment interactions explain more phenotypic variance than main effects, pinpoint regulatory variants, and reveal exposure‐specific biological pathways.

Epigenetic Targeting of Senescent Cells Prevents the Deleterious Effects of Obstructive Sleep Apnea on Growing Skeleton

open access: yesAdvanced Science, EarlyView.
Chronic intermittent hypoxia induces premature senescence of osteoprogenitor cells in long bone metaphysis via HIF1α‐mediated EZH2‐H3k27me3 downregulation, leading to impaired bone growth. Restoration of H3K27me3 level via UTX inhibition rescues osteogenesis and growth impairment in young mice.

A Patient‐Derived Organoid Biobank of Adamantinomatous Craniopharyngioma as a Platform for Drug Discovery

open access: yesAdvanced Science, EarlyView.
This study successfully establishes adamantinomatous craniopharyngioma (ACP) patient‐derived organoids (PDOs) that preserve the histopathological and genetic features of the original tumors. Through drug sensitivity assays and subsequent mechanistic analyses, the study demonstrates that Ceritinib exerts its inhibitory effects on ACP PDO growth by ...

Forelimb Motor Learning and Memory Consolidation Drives Distinct Oligodendrocyte Plasticity to Regulate Task‐related Neuronal Activity

open access: yesAdvanced Science, EarlyView.
Genetic and chemical tracking of oligodendrogenesis, combining fiber photometric neuronal activity recording, reveals that distinct oligodendrocyte plasticities are adopted during different phases of motor learning to fine‐tune task‐related neuronal activity, with a preferential involvement of oligodendrogenesis suppression and node lengthening (type 2
