Arhgef1 Deletion Disrupts Early Cortical Neurogenesis via PAK1 Overactivation and Causes Motor Dysfunction in Adulthood

open access: yesAdvanced Science, EarlyView.
ARHGEF1 plays a pivotal role in both embryonic cortical neurogenesis and adult motor function. During early development, it governs genesis of deep‐layer cortical neurons by negatively regulating RAC1/CDC42‐PAK1‐Cofilin signaling. In adulthood, ARHGEF1 is important for the maintenance of neuronal morphology and activity in the motor cortex, ensuring ...

BRCA1 Mutation‐Recognizing Tetrahedral Framework Nucleic Acid Nanoplatform Enables Coordinated PARP/WEE1 Inhibition and STING‐Associated Antitumor Immunity in Ovarian Cancer

open access: yesAdvanced Science, EarlyView.
BRCA1 mutation‐responsive FBOA‐tFNA selectively recognizes mutant transcripts and coordinates reduction‐responsive intracellular delivery of olaparib and adavosertib, amplifying DNA damage and weakening G2/M checkpoint protection. These effects are accompanied by STING‐associated immune activation and stronger antitumor immunity, while sequential anti ...

Ischemic Postconditioning Protects Aged Myocardium Against Ischemia/Reperfusion Injury by Regulating Mitochondrial Dynamics via piR‐4913

open access: yesAdvanced Science, EarlyView.
A tiny RNA tips the scales of cardiac injury in aging. piR‐4913 recruits OGT to Drp1 and drives its O‐GlcNAcylation at Thr604, promoting excessive mitochondrial fission that aggravates ischemia‐reperfusion injury. Ischemic postconditioning silences this pathway to restore mitochondrial balance and protect the aged myocardium, revealing piR‐4913 as a ...

Lactate Drives Pathological Browning of White Adipose Tissue to Aggravate Sepsis‐Associated Metabolic Disorders in a GPR81‐Dependent Manner

open access: yesAdvanced Science, EarlyView.
Sepsis‐triggered lactate accumulation induces pathological white adipose tissue browning. Lactate activates adipocyte GPR81 to sequentially upregulate CTRP6‐p38 signalling and UCP1 expression. This cascade exacerbates sepsis‐associated metabolic disorders.

3′‐UTR Hypermethylation and ABA Signaling Coordinate Transcriptional Activation of SWEET14 for High Sugar Accumulation in Citrus

open access: yesAdvanced Science, EarlyView.
Hypermethylation of CliSWEET14 3′‐UTR relieves ClibHLH105‐mediated transcriptional repression, together with ABA signaling‐mediated activation of the CliABF3‐CliNAC56 cascade, boosts CliSWEET14 expression and sucrose accumulation in citrus. ABSTRACT Sugar accumulation is pivotal for fruit quality, yet the molecular regulation of this process remains ...
