Microfilament‐Myosin II Regulates the Differentiation of Multinucleated Cysts into Oocytes and Influences Oocyte Developmental Potential in Mice

open access: yesAdvanced Science, EarlyView.
In this study, we provided new evidence identifying multinucleated cysts as precursors for oocyte differentiation. Within these cysts, organelles migrate and aggregate to form Balbiani body (B‐body) and establish early cellular polarity. Concurrently, excess nuclei are expelled, enabling cyst‐to‐oocyte differentiation. The microfilament‐myosin II plays

Integrative Omics Reveals Glutamine Catabolism‐Driven Apoptotic Suppression in Monocytes upon Mechanical Unloading

open access: yesAdvanced Science, EarlyView.
This research integrated multi‐omics analysis of bone tissue from HLU and control mice revealed that mechanical unloading suppresses intrinsic apoptosis and augments glutamine (Gln) catabolism in osteoclast lineage cells. The findings highlight pivotal roles for SLC1A5‐mediated Gln metabolism and XIAP/Diablo axis‐mediated apoptosis suppression.

Osteoblast‐CD4+ CTL Crosstalk Mediated by SIRT1/DAAM2 Axis Prevents Age‐Related Bone Loss

open access: yesAdvanced Science, EarlyView.
In the osteoblastic niche, SIRT1 activates and recruits CD4+ CTLs by increasing DAAM2 expression via EZH2 deacetylation and boosting the secretion of key chemokines, such as CCL3, CCL5, and CXCL10. Then, CD4+ CTL directly eliminates senescent osteoblasts in an MHC‐II‐dependent way, thereby slowing down the process of bone ageing and effectively ...

PRDM16 Reduces Cellular Senescence by Upregulating GSTM1

open access: yesAdvanced Science, EarlyView.
Cellular senescence drives aging and aging‐related organ disorders, yet PRDM16's role remains unexplored. This work uncovers that PRDM16 decreases significantly in aged organs, while its loss accelerates cellular senescence and aging‐related organ injury.

A Peripheral Mechanism of Depression: Disturbed Intestinal Epithelial Per2 Gene Expression Causes Depressive Behaviors in Mice with Circadian Rhythm Disruption via Gut Barrier Damage and Microbiota Dysbiosis

open access: yesAdvanced Science, EarlyView.
Circardian rhythm disorder (CRD) causes abnormal expression of intestinal Period 2 (Per2) gene, which compromising intestinal barrier integrity and altering the gut microenvironment. Microbiota dysbiosis and aberrant metabolites production drive central inflammation, impair neurogenesis, and promote functional deficits, ultimately facilitating the ...

Glycolytic Enzyme HK2 Phosphorylates nSMase1 to Promote Astrocytic Exosomes Biogenesis Contributing to Acute Ischemic Stroke Injury

open access: yesAdvanced Science, EarlyView.
This study reveals that the glycolytic enzyme HK2 mediates hypoxia‐induced astrocytic exosome biogenesis by directly phosphorylating nSMase1. These astrocytic exosomes impair brain endothelial tight junctions. Astrocyte‐specific knockdown of HK2 reduces exosome release and alleviates brain injury after MCAO.

A Prion‐Like Domain in EBV EBNA1 Promotes Phase Separation and Enables SRRM1 Splicing

open access: yesAdvanced Science, EarlyView.
This study discoveries that EBV EBNA1 behaves as a prion‐like protein, verified using cell‐based assays and the Saccharomyces cerevisiae Sup35p prion identification system. The prion‐like domain of EBNA1 drives liquid–liquid phase separation. EBNA1 interacts with the splicing factor SRSF1 to regulate the expression of the SRRM1 splicing isoforms ...

Weak and Tunable Adhesion–Clutch Drives Rapid Cell Migration and Glioblastoma Invasion

open access: yesAdvanced Science, EarlyView.
This study proposes that adhesion–clutch can mediate both cell motility and immobilization depending on the force amplitude. Weak adhesion–clutch is well‐suited for cell migration, without forming strong adhesions that impede cell motility. It propels rapid dendritic cell migration controlled by extracellular chemicals, as well as pathologically ...
