Milky Way Dark Matter Distribution or MOND Test from Vertical Stellar Kinematics with Gaia DR3

The Astrophysical Journal
Vertical stellar kinematics+density can be used to trace the dark matter distribution (or the equivalent phantom mass in a Modified Newtonian Dynamics (MOND) scenario) through the Jeans equations.

RFWD3 Reprograms Nucleotide Metabolism Through PHGDH to Induce Chemoresistance In Osteosarcoma

Advanced Science, EarlyView.
RFWD3 is identified as a key regulator of cisplatin (DDP) sensitivity in osteosarcoma using a genome‐wide CRISPR screen. RFWD3 promotes PHGDH ubiquitination, enhancing NAD+‐mediated nucleotide biosynthesis. Knocking out RFWD3 sensitized osteosarcoma cells to DDP.

Segue 2 Recently Collided with the Cetus-Palca Stream: New Opportunities to Constrain Dark Matter in an Ultra-faint Dwarf

The Astrophysical Journal
Stellar streams in the Milky Way are promising detectors of low-mass dark matter (DM) subhalos predicted by ΛCDM. Passing subhalos induce perturbations in streams that indicate the presence of the subhalos. Understanding how known DM-dominated satellites

TRAF3IP3 Induces ER Stress‐Mediated Apoptosis with Protective Autophagy to Inhibit Lung Adenocarcinoma Proliferation

Advanced Science, EarlyView.
Schematic diagram of the working model of TRAF3IP3 in the coordination of ER stress and autophagy related apoptosis in lung cancer cells. Abstract TNF receptor‐associated factor 3 interacting protein 3 (TRAF3IP3/T3JAM) exhibits dual roles in cancer progression. While upregulated in most malignancies and critical for immune regulation.

N4‐Acetylcytidine‐Mediated CD2BP2‐DT Drives YBX1 Phase Separation to Stabilize CDK1 and Promote Breast Cancer Progression

Advanced Science, EarlyView.
The long non‐coding RNA (lncRNA) CD2BP2‐DT is upregulated in breast cancer and correlates with poor patient prognosis. Mechanistically, CD2BP2‐DT drives YBX1 phase separation to stabilize CDK1 and promote breast cancer progression. Moreover, NAT10‐mediated N4‐acetylcytosine (ac4C) modification further enhances CD2BP2‐DT expression.

P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

Advanced Science, EarlyView.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...

Integrative Multi‐Omics Approaches Reveal Selectivity Profiles and Molecular Mechanisms of FIIN‐2, a Covalent FGFR Inhibitor

Advanced Science, EarlyView.
Using integrative multi‐omics analyses, this study maps FIIN‐2's targets and signaling networks in liver cancer cells, and identifies covalent AMPKα1 binding as a novel autophagy‐activating mechanism. The findings resolve both on‐target FGFR inhibition and off‐target protein engagement, providing a molecular roadmap to refine covalent kinase inhibitors

Conditional Overexpression of Serpine2 Promotes Hair Cell Regeneration from Lgr5+ Progenitors in the Neonatal Mouse Cochlea

Advanced Science, EarlyView.
This study indicates that Serpine2 plays a pivotal role in hair cell (HC) regeneration from Lgr5+ progenitors in the neonatal mouse cochlea. Conditional overexpression of Serpine2 in cochlear Lgr5+ progenitors results in a significantly increased number of ectopic HCs, particularly ectopic inner HCs, and these HCs are likely derived from Lgr5 ...

CpG‐Based Nanovaccines Enhance Ovarian Cancer Immune Response by Gbp2‐Mediated Remodeling of Tumor‐Associated Macrophages

Advanced Science, EarlyView.
CpG‐based nanovaccines bolster ovarian cancer immunotherapy via the Gbp2‐Pin1‐NFkB pathway‐mediated reprogramming of tumor‐associated macrophages (TAMs.) Moreover, this nanovaccine can alleviate chemotherapy‐induced immunosuppression by augmenting the proportion of M1‐like TAMs, enhancing the infiltration of CD8+ T cells, and downregulating the ...

Icaritin Represses Autophagy to Promote Colorectal Cancer Cell Apoptosis and Sensitized Low‐Temperature Photothermal Therapy via Targeting HSP90‐TXNDC9 Interactions

Advanced Science, EarlyView.
Icaritin demonstrates broad antitumor effects by inhibiting colorectal cancer (CRC) cell proliferation, migration, invasion, and causing cell cycle arrest. It induces apoptosis by repressing autophagic flux through disrupting HSP90‐TXNDC9 interactions.
