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 ...

PIAS3 CircRNA‐Loaded Lipid Nanoparticles Restore ALOX15 SUMOylation to Suppress Cementoblast Ferroptosis and Attenuate Orthodontically Induced Root Resorption

open access: yesAdvanced Science, EarlyView.
Orthodontic compression suppresses PIAS3 expression in cementoblasts, impairing ALOX15 SUMOylation and ubiquitin‐mediated degradation, which leads to ALOX15 accumulation, lipid peroxidation, ferroptosis, and osteoclastogenesis. Local delivery of PIAS3 circRNA‐loaded lipid nanoparticles restores the PIAS3–ALOX15 regulatory pathway, alleviates ...

Current Status and Challenges of Imaging‐Based Diagnosis of Lymph Node Metastasis in Colon Cancer: The Lymph Node Committee of the Japanese Society for Cancer of the Colon and Rectum

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This review of the status and challenges of diagnosis of lymph node metastasis in colon cancer suggests that it is currently difficult to establish strict criteria for lymph node metastasis, indicating only moderate diagnostic performance. ABSTRACT Background Accurate pre‐treatment evaluation of lymph node metastasis (LNM) in colon cancer is important ...

Cell Segmentation Beyond 2D—A Review of the State‐of‐the‐Art

open access: yesAdvanced Intelligent Discovery, EarlyView.
Cell segmentation underpins many biological image analysis tasks, yet most deep learning methods remain limited to 2D despite the inherently 3D nature of cellular processes. This review surveys segmentation approaches beyond 2D, comparing 2.5D and fully 3D methods, analyzing 31 models and 32 volumetric datasets, and introducing a unified reference ...

Baihe Zhimu Decoction ameliorates anxious depression via PI3K/AKT/mTOR pathway‐mediated neuroprotection and inhibition of hippocampal neuronal apoptosis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Baihe Zhimu Decoction alleviates anxious depression‐like behaviors and protects hippocampal neurons. Chemical profiling and network pharmacology reveal multiple active components acting via the PI3K/AKT/mTOR pathway, enhancing neuronal survival and function, as confirmed by multi‐level in vitro and in vivo validation.

In Vivo Nb4C3Tx MXene‐Assisted Photothermal Therapy of Melanoma in Mice

open access: yesAdvanced NanoBiomed Research, EarlyView.
Nb4C3Tx MXene converts pulsed 1064 nm irradiation into localized heat, producing concentration‐ and time‐dependent melanoma cell killing in vitro and suppressing tumor growth in mice. Histology reveals extensive tumor damage, macrophage‐associated material clearance, and no detectable persistent deposits in examined visceral organs, supporting Nb4C3Tx ...
