Gastrula‐Premarked Posterior Enhancer Primes Posterior Tissue Development Through Cross‐Talk with TGF‐β Signaling Pathway

open access: yesAdvanced Science, EarlyView.
A gastrula‐premarked enhancer within the first intron of Cdx2 governs posterior embryonic development via both regulating Cdx2 expression in cis and coordinating TGF‐β signaling in trans to ensure proper posterior body development. Functional rescue in gastruloids reveals a Cdx2‐independent pathway, highlighting p‐Enh‐eRNA as key epigenetic ...

5’‐Methylthioadenosine Metabolic Reprogramming Drives H3K79 Monomethylation‐Mediated PAK2 Upregulation to Promote Cadmium‐Induced Breast Cancer Progression by Impairing Autophagic Flux

open access: yesAdvanced Science, EarlyView.
Cadmium, a carcinogenic heavy metal, drives breast cancer progression via metabolic reprogramming and autophagic flux disruption. Multi‐omics revealed cadmium‐induced 5'‐methylthioadenosine depletion activates DOT1L‐mediated H3K79me1 at PAK2 promoter, upregulating PAK2 to block autophagy and driving malignancy. Clinically, 5'‐methylthioadenosine levels

Gamma‐Glutamyl Cysteine Ligase Activity as a Proxy for Human T Cell Function and Drug‐Induced Immunosuppression

open access: yesAdvanced Science, EarlyView.
GLed, a reversible lanthanide‐based GSH sensor that enables real‐time, single‐cell measurement of Gamma–Glutamyl Cysteine Ligase (GCL) activity ‐whose role in human T cells remains unclear‐ is developed. GLed directly links GCL activity to T cell effector functions and reveals its modulation by immunosuppressive drugs, identifying GCL as a critical ...

RPL6 Interacts with HMGCS1 to Stabilize HIF‐1α by Promoting Cholesterol Production in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
The study found that RPL6 is frequently upregulated in HCC tissues with extrahepatic metastasis. Elevated RPL6 bound to and increased the stability of HMGCS1 mRNA, thereby enhancing intracellular cholesterol levels. Subsequently, increased cholesterol promotes cancer metastasis in HCC by stabilizing HIF‐1α protein.

STAT6 Activation Exacerbates Ferroptosis in Airway Epithelium by Inhibiting PRKN‐Mediated Mitophagy in Pulmonary Fibrosis

open access: yesAdvanced Science, EarlyView.
This study uncovers STAT6‐driven pulmonary fibrosis (PF) via suppression of PRKN‐mediated airway epithelial mitophagy, triggering mitochondrial dysfunction and ferroptosis. Rifabutin is identified as a potent STAT6 inhibitor that effectively reverses fibrotic progression. These findings reveal the STAT6‐PRKN axis as a pathogenic regulator and provide a

E3 Ligases Regulate Organelle Inheritance in Yeast

open access: yesCells
Saccharomyces cerevisiae proliferates by budding, which includes the formation of a cytoplasmic protrusion called the ‘bud’, into which DNA, RNA, proteins, organelles, and other materials are transported.
