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

Advanced 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.

PRDM16 Reduces Cellular Senescence by Upregulating GSTM1

Advanced 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.

Ursa Major III/UNIONS 1: The Darkest Galaxy Ever Discovered?

The Astrophysical Journal
The recently discovered stellar system Ursa Major III/UNIONS 1 (UMa3/U1) is the faintest known Milky Way satellite to date. With a stellar mass of ${16}_{-5}^{+6}\,{M}_{\odot }$ and a half-light radius of 3 ± 1 pc, it is either the darkest galaxy ever ...

The Pathogenic Roles of Local Vitamin D Metabolism Defect in Valve Inflammation and Calcification

Advanced Science, EarlyView.
This study identifies the valvular interstitial cell populations responsible for valvular calcification induced by hyperphosphatemia and likely aging, uncovers local vitamin D metabolism defect‐induced inflammation as a critical pathogenic factor of calcific aortic valve disease, and highlights active vitamin D and ERK inhibitor as potential preventive

Hepatitis E Virus ORF1 Polyprotein Harbors a Pocket‐Like Cavity That Is Vital for Virus Replication and Represents a Novel Antiviral Target

Advanced Science, EarlyView.
Within the hepatitis E virus (HEV) ORF1 polyprotein, the X domain interacts with viral RNA‐dependent RNA polymerase (RdRp), forming a functional “pocket‐like” cavity (PC) that is crucial for viral replication. Structure‐based screening, surface plasmon resonance (SPR) assays, and HEV model validation collectively identify saikosaponin D and ...

Dynamic Arginine Methylation of YBX1 Relay Controls Its Phase Separation and Chemoradiotherapy Resistance in Rectal Cancer

Advanced Science, EarlyView.
Protein arginine methyltransferase 3 (PRMT3) induces the arginine methylation of Y‐box binding protein 1 (YBX1), which suppresses phase separation and is imperative for its nuclear translocation. Subsequently, lysine‐specific demethylase 4A demethylates YBX1 to unmask the R247 residue and promote its phase separation, which transcriptionally regulates ...

Identification of Blue Horizontal-branch Stars Using Synthetic SkyMapper Colors from Gaia XP Spectra

The Astrophysical Journal Supplement Series
Blue horizontal-branch (BHB) stars are ideal tracers for mapping the structure of the Galactic stellar halo. Traditionally, BHB sample stars are built from large-scale spectroscopic surveys utilizing their spectral features; however, the resulting sample

FOXQ1 Regulates Brain Endothelial Mitochondrial Function by Orchestrating Calcium Signaling and Cristae Morphology

Advanced Science, EarlyView.
FOXQ1 emerges as a master transcriptional regulator of brain endothelial metabolism, orchestrating mitochondrial function through dual control of calcium signaling and cristae organization. This study reveals that brain endothelial cells rely on oxidative phosphorylation rather than glycolysis alone, challenging the current metabolic paradigm and ...
