YAP1‐Driven Pathogenic Fibro‐Adipogenic Progenitors Secrete IL‐6 and FGF21 to Mediate Muscle‐Bone Crosstalk and Promote Bone Loss

Advanced Science, EarlyView.
Fibro‐adipogenic progenitors (FAPs) in atrophic muscle undergo YAP1‐driven pathogenic activation, secreting IL‐6 and FGF21 as bone‐catabolic myokines that mediate muscle‐bone crosstalk and promote bone loss. Genetic or pharmacological targeting of this YAP1‐FAP‐myokine axis rescues skeletal deterioration, identifying FAP‐derived myokines as therapeutic

Evaluation of oestrogen and progesterone receptor status in HER-2 positive breast carcinomas and correlation with outcome

, 2006
Aim: HER-2/neu amplification occurs in 15-25% of breast carcinomas. This oncogene, also referred to as c-erbB-2, encodes a transmembrane tyrosine kinase receptor belonging to the epidermal growth factor receptor family.

Intratumoral Hypoxia Triggers Mitochondrial BHLHE40 ROS Sensing Pathway to Promote Radioresistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
Hypoxia triggers a dual mechanism for BHLHE40 upregulation: reactive oxygen species (ROS)‐dependent post‐translational modification and hypoxia‐inducible factor (HIF)‐dependent transcriptional activation. Under hypoxic conditions, mitochondrial BHLHE40 accumulates and senses ROS via cysteine thiol oxidation and disulfide‐linked homodimer formation ...

Tumor‐Derived Exosomal circAP2B1 Induces M2 Macrophage Polarization by Enhancing Mitochondrial Homeostasis to Promote Esophageal Squamous Cell Carcinoma Progression

Advanced Science, EarlyView.
ESCC‐derived exosomal circAP2B1 promotes tumor progression by reprogramming mitochondrial metabolism via the ESRRA/KPNA1/MFN2 axis to induce M2 polarization of macrophages. ABSTRACT Esophageal squamous cell carcinoma (ESCC) remodels the immunosuppressive tumor microenvironment via exosome‐mediated intercellular communication.

Aromatase inhibition remodels the clonal architecture of estrogen-receptor-positive breast cancers

Nature Communications, 2016
Aromatase inhibitors are used to treat oestrogen-receptor-positive breast cancer. Here, the authors use genomic approaches to analyse tumours before and after neo-adjuvant treatment and find that treatment alters the clonal landscape of the tumours.

Nanoparticle‐Mediated TIPE1 mRNA Delivery Enhances Paclitaxel Sensitivity in Triple‐Negative Breast Cancer by Modulating RAB7A Ubiquitination‐Associated Stability and Autophagy

Advanced Science, EarlyView.
TIPE1m NPs nanoparticles restore TIPE1 expression, promote RAB7A ubiquitination and degradation, suppress autophagic flux, and resensitize paclitaxel‐resistant triple‐negative breast cancer to therapy. ABSTRACT Acquired paclitaxel (PTX) resistance remains a major obstacle in triple‐negative breast cancer (TNBC) treatment.

Transcription Factor HOXC11 Drives Colorectal Cancer Progression and Metastasis via CAMK2A‐Dependent CXCL5 Upregulation

Advanced Science, EarlyView.
HOXC11 drives colorectal cancer progression by transcriptionally activating CAMK2A, which triggers NF‐κB–dependent CXCL5 upregulation. CXCL5–CXCR2 signaling further reinforces HOXC11 expression through the ERK1/2–SP1 axis, forming a prometastatic positive feedback loop that is effectively disrupted by combined CAMK2A and CXCR2 inhibition.

SemanticST: A Scalable Multi‐Contextual Graph Learning Framework for Uncovering Spatial Niches and Robust Multi‐Sample Integration in Spatial Transcriptomics

Advanced Science, EarlyView.
Technical limitations often let dominant signals overshadow rare cell types and fine‐grained heterogeneity in spatial transcriptomics. SemanticST, a graph neural network using multi‐semantic graph fusion and a novel min‐cut loss, recovers these subtle patterns.
