Quantifying the Single‐Cell Morphological Landscape of Cellular Transdifferentiation through Force Field Reconstruction

open access: yesAdvanced Science, EarlyView.
This study reconstructs the driving force field of fibroblast‐to‐neuron transdifferentiation from sparse single‐cell images by decomposing it into flux and time‐dependent potential gradient, extending the landscape‐flux framework to non‐steady‐state systems.

Glucocorticoid Receptor Activation Reprograms NK Cells to Drive AREG‐Mediated Immunosuppression: A Pan‐Cancer Role for AREG

open access: yesAdvanced Science, EarlyView.
Natural killer cells, central to anti‐tumor defense, undergo unexpected reprogramming within the tumor microenvironment. Instead of producing IFN‐γ and TNF‐α, they elevate amphiregulin, a tumor‐promoting factor. This shift is linked to glucocorticoid receptor activity and prostaglandin signaling.

Relationships between the dynamics of two Talitrus saltator populations and the impacts of activities linked to tourism

open access: yesOceanologia, 2005
The study considered two ecologically similar coastal areas in Tuscany (Italy).One site belongs to a protected natural area and the other one is infront of a camping site.

Ex Vivo Spatiotemporal Characterization of Spermatogenesis in Mouse Testicular Organoids

open access: yesAdvanced Science, EarlyView.
To date, in vitro spermatogenesis remains a challenge in reproductive medicine. In this study, Sun et al. developed a promising in vitro strategy to generate testicular organoids that enable germ cells from newborn mice to enter meiosis, complete chromosome recombination and synapsis, and develop into haploid spermatids.

Surface‐Associated Proteins on Extracellular Vesicles Remodel the Tumor Microenvironment by Potentiating TGF‐β Signaling in a Contact‐Dependent Manner

open access: yesAdvanced Science, EarlyView.
Extracellular vesicles (EVs) released from TGF‐β‐activated CAFs are enriched with ECM proteins such as TSG6 and THBS1, which facilitate their binding to recipient cell membranes. This EV–cell interaction promotes the clustering of CD44 and TGF‐β receptors on the target cell surface, thereby potentiating TGF‐β signaling activity. This study highlights a

Astrocytic PCBP1 Suppresses Ferroptosis to Restore Glutamatergic Homeostasis and Mitigate Stress‐Induced Depression in Male Mice

open access: yesAdvanced Science, EarlyView.
This study demonstrates that polyC‐RNA‐binding protein 1 (PCBP1) in ventral hippocampal astrocytes modulates depressive‐like behaviors by regulating glutathione peroxidase 4‐mediated ferroptosis and synaptic glutamatergic transmission. PCBP1 overexpression intervention in the chronic unpredictable mild stress model rescues behavioral deficits ...

Integrated ERK‐PKA‐YAP/TAZ‐SHH Signaling Orchestrates Cortical Radial Glia Identity and Lineage Diversification

open access: yesAdvanced Science, EarlyView.
This study shows that ERK/PKA upregulation in mammalian cortical radial glia (RGs) sustains neurogenesis and suppresses gliogenesis. YAP/TAZ activation promotes ependymal cell formation, while enhanced SHH‐SMO signaling induces astrocyte, oligodendrocytes, and olfactory bulb interneuron generation.

Hungry for Knowledge: Octopamine Signaling Regulates Hunger‐Enhanced Olfactory Learning

open access: yesAdvanced Science, EarlyView.
Researchers demonstrate that hunger state facilitates both aversive and appetitive olfactory learning. Two distinct octopamine signaling pathways are involved in aversive or appetitive memory formation in the hunger state. And, hunger state also facilitates the formation of both types of memories via an evolutionarily conserved norepinephrine (the ...
