KRAS Withdrawal in Cholangiocarcinoma Leads to Immune Infiltration and Tumor Regression

Advanced Science, EarlyView.
Cholangiocarcinoma (CCA) driven by oncogenic KRAS depends on its continuous activation for tumor maintenance. Using a conditional KRAS model, the authors show that turning off KRAS triggers rapid tumor regression accompanied by immune cell infiltration and cytokine release. The findings uncover a KRAS–senescence–immune signaling axis and highlight KRAS

An Opto‐Actuated Hydrogel for Cell Mechanoactuation and Real‐Time Force Monitoring

Advanced Science, EarlyView.
Researchers developed a mechanoactuated hydrogel interface where nanomachines exert forces on adhesion receptors and allow monitoring of traction force responses in real time. They demonstrate reversible talin recruitment, enhanced F‐actin polymerization, and a reduction in cell traction force when force is locally applied to focal adhesions of ...

TAS1R3 influences GTPase-dependent signaling in human islet β-cells

Frontiers in Endocrinology
BackgroundThe taste receptor type 1 member 3 (TAS1R3), a G protein-coupled receptor (GPCR), is expressed in pancreatic islet β-cells where it may influence intracellular signaling pathways critical for β-cell function.

Soybean Auxin Transporter PIN3 Regulates Nitrate Acquisition to Improve Nitrogen Use and Seed Traits

Advanced Science, EarlyView.
Xu et al. discovers that switching off auxin transporters in soybean, PIN3a and PIN3b, disrupts auxin flow; this triggers ARF‐STF3/4 signal cascade to activate the nitrate importer NPF2.13 and soil nitrogen acquisition. Multi‐year field trials show edited soybeans maintain yield with higher oil content, offering a potential genetic route to improve ...

Smoking‐Induced STC2+ Tumor Cells Drive Tumor‐Vascular Crosstalk in Laryngeal Squamous Cell Carcinoma via Spatial and Single‐Cell Transcriptomics

Advanced Science, EarlyView.
This study identifies a smoking‐induced mechanism in LSCC whereby nicotine activates the CHRNA5–JAK2/STAT3 axis to drive STC2 transcription. STC2 upregulates TGFBI, which interacts with endothelial ITGA5 to regulate vascular permeability and promote metastasis.

Contribution of Gli1+ Adventitial Stem Cells to Smooth Muscle Cells in Atherosclerosis and Vascular Injury

Advanced Science, EarlyView.
Gli1+ adventitial stem cells (ASCs) have been thought to generate smooth muscle cells (SMCs) in atherosclerosis. Using a dual‐recombinase lineage tracing to exclude ectopic labeling, Wang et al. found that Gli1+ ASCs do not contribute to SMCs in atherosclerotic plaques.

Proteogenomic Characterization Reveals Subtype‐Specific Therapeutic Potential for HER2‐Low Breast Cancer

Advanced Science, EarlyView.
Multiomic profiling of HER2‐low breast cancer identifies three proteomic subtypes with distinct therapeutic strategies: endocrine, antiangiogenic, and anti‐HER2 therapies. Genomic and lactate modification landscapes are detailed, providing insights for precise management.

Dual Targeting of Mutant p53 and SNRPD2 via Engineered Exosomes Modulates Alternative Splicing to Suppress Ovarian Cancer

Advanced Science, EarlyView.
Mutant p53 drives oncogenic splicing to promote the progression of ovarian cancer by partnering with the spliceosome factor SNRPD2. Therefore, it is engineered iRGD‐exosomes to co‐deliver siRNAs against both targets. This approach restored tumor‐suppressive mRNA isoforms, effectively enhanced sensitivity to cisplatin, and ultimately blocked tumor ...

Increased Blood Flow and Tendon Swelling Precedes Vascular Expansion and Tissue Matrix Changes In Early Human Tendinopathy: A Potential Window for Superior Treatment Response

Advanced Science, EarlyView.
Human participants with early‐ or chronic‐stage tendinopathy and healthy controls are investigated using ultrasound Doppler, 3T and 7T MRI, and tendon biopsies. Tendon swelling and hyperperfusion are evident early, while vascular growth and extracellular matrix changes are most pronounced in chronic tendinopathy. Early intervention may provide superior
