Mutant KRAS‐m6A Epitranscriptome Axis Promotes Colorectal Cancer and is a Therapeutic Target

Advanced Science, EarlyView.
Mutant KRAS‐m6A axis promotes colorectal cancer (CRC) progression. Mutant KRAS stabilizes METTL3, leading to increased m6A‐modified BCL9L mRNA and translation of BCL9L protein. BCL9L in turn mediates TGF‐β secretion to induce differentiation of Treg and an immunosuppressive microenvironment.

TFEB drives mTORC1 hyperactivation and kidney disease in Tuberous Sclerosis Complex

Nature Communications
Tuberous Sclerosis Complex (TSC) is caused by TSC1 or TSC2 mutations, leading to hyperactivation of mechanistic target of rapamycin complex 1 (mTORC1) and lesions  in multiple organs including lung (lymphangioleiomyomatosis) and kidney (angiomyolipoma ...

PTBP1‐Mediated Alternative Splicing of DNAJB6 Promotes Everolimus Resistance in Clear Cell Renal Cell Carcinoma via EIF4B/PKIB/AKT/mTOR Positive Feedback Loop

Advanced Science, EarlyView.
PTBP1‐mediated alternative splicing drives a pathogenic switch to the DNAJB6b isoform in everolimus‐resistant clear cell renal cell carcinoma. This splicing event programs a positive feedback loop including EIF4B/PKIB/AKT/mTOR, promoting aggressive therapy resistance.

SAT1‐Induced Spermidine Depletion Potentiates Food Allergy

Advanced Science, EarlyView.
Spermidine depletion, driven by upregulated spermidine/spermine N1‐acetyltransferase (SAT1), potentiates food allergy by promoting mast cell degranulation through autophagy suppression. SAT1 physically interacts with the long noncoding RNA Cdk19os to inhibit Atg5 and Atg7, disrupting autophagic flux.

Cortisol promotes placental glucose and amino acids transport by activating the mechanistic target of rapamycin complex 1 signaling pathway

Journal of Animal Science
Abstract Low birth weight (LBW) has been an important problem in animal husbandry, contributing to high mortality and morbidity rates in the neonatal period. To explore the mechanism regulating placental function and fetal development, paired normal birth weight (NBW, 1.54 ± 0.08 kg) and LBW (0.95 ± 0.16 kg) piglets (n = 10) were ...

Persistent Zn2+ Influx‐Mediated Deacetylation of ANXA2 Regulates the “Zn2+‐Autophagic Flux” and Alleviates Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Zinc transporter SLC39A14 sustains intracellular Zn2+ levels to activate SIRT3‑dependent ANXA2 deacetylation at K302. This modification weakens ANXA2‑mTOR binding and releases autophagic‑flux suppression in nucleus pulposus cells. Dysregulated Zn2+ homeostasis disrupts this axis to drive intervertebral disc degeneration.

mTORC1 signaling in group 2 innate lymphoid cells coordinates neuro-immune crosstalk in allergic lung inflammation

Nature Communications
Group 2 innate lymphoid cells (ILC2) initiate pathologic type 2 inflammation in allergic asthma in response to diverse tissue-derived stimuli. However, the molecular mechanisms by which ILC2 cells integrate and respond to environmental signals are ...

Cerebral Organoid Modeling Reveals That Suppression of Aberrant mTOR Pathway Activation Alleviates Hyperbaric Oxygen-Induced Neurotoxicity

Engineering
This study established human cerebral organoids as a promising platform for investigating central nervous system oxygen toxicity (CNS-OT). Through integrated transcriptomic, functional, and pharmacological analyses, we demonstrate that hyperbaric oxygen (
