Modern and Ancient Genomes Reveal Neolithic Paternal Expansions of Millet and Rice Farmers and Demic Diffusion from China into Mainland Southeast Asia

open access: yesAdvanced Science, EarlyView.
This study clarifies the genetic patterns of paternal lineages across East Asia and Mainland Southeast Asia. Han populations are relatively homogeneous, whereas southern ethnolinguistic minorities display regional structures. Shared Y‐chromosome lineages indicate Neolithic expansions and extensive north‐south gene flow, supporting demic diffusion ...

Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

open access: yesAdvanced Science, EarlyView.
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.

3D Bioprinted Fat‐Myocardium Model Unravels the Role of Adipocyte Hypertrophy in Atrial Dysfunction

open access: yesAdvanced Science, EarlyView.
A human‐derived 3D bioprinted fat–myocardium model is developed to investigate how adipocyte hypertrophy drives atrial dysfunction in obesity. Palmitate‐induced adipocyte hypertrophy promotes adipose dysfunction that impairs atrial cardiomyocyte metabolism and electrophysiology through both paracrine and direct interactions. This platform recapitulates

Pirin Transcriptionally Regulates PLA2G4A To Inhibit Ferroptosis in Colorectal Cancer via Lipid Profile Remodeling

open access: yesAdvanced Science, EarlyView.
This study identifies Pirin (PIR), an iron‐binding protein, as a critical ferroptosis suppressor in colorectal cancer through lipid membrane remodeling. PIR, induced by NRF2 during ferroptotic stress, transcriptionally regulates PLA2G4A to shift cellular lipid composition away from ferroptosis‐permissive polyunsaturated phospholipids.

Magnetic Resonance Imaging Reveals Meningeal Lymphatic Impairment in Lung Adenocarcinoma Brain Metastasis Progression

open access: yesAdvanced Science, EarlyView.
This study demonstrates meningeal lymphatic impairment associated with lung adenocarcinoma brain metastasis progression in both human patients and mouse models, establishes clinically applicable non‐invasive imaging biomarkers for quantitative analyzing mLV structure and function, and reveals mLVs as robust prognostic indicators and promising potential
