Imaging‐Guided Live Single‐Cell Lipid Profiling of Leader and Follower Cellsduring Collective Migration of Triple‐Negative Breast Cancer Cells

Advanced Science, EarlyView.
Integrated single‐cell mass spectrometry reveals distinct lipidomic signatures that differentiate leader and follower phenotypes in migratory breast cancer cells. Phenotype‐specific alterations across various lipid classes, including fatty acids and phosphatidylcholines, underpin functional heterogeneity.

CEBPG‐Mediated Palmitic Acid Adaptation of Cancer‐Associated Fibroblasts Drives Metastasis of Oral Squamous Cell Carcinoma

Advanced Science, EarlyView.
This study reveals a metabolic signaling axis in the OSCC microenvironment where palmitic acid (PA) drives the activation of CAFs. PA uptake triggers CEBPG‐dependent epigenetic remodeling to upregulate ERN1 and TMBIM6, thereby mitigating ER stress. This adaptive program sustains CAF survival and the pro‐metastatic phenotype, establishing this pathway ...

Epithelial mesenchymal transition and cancer stem cell markers in oral epithelial dysplasia and oral squamous cell carcinoma

Polish Journal of Pathology
The role of cancer stem cells (CSC) in oral cancer is widely accepted. Yet, the existence of CSC in dysplastic tissue and the molecular pathways of progression from dysplasia to malignancy remain to be explored.

Piezo2 interacts with E-cadherin in specialized gastrointestinal epithelial mechanoreceptors

Journal of General Physiology
Piezo2 is a mechanically gated ion channel most commonly expressed by specialized mechanoreceptors, such as the enteroendocrine cells (EECs) of the gastrointestinal epithelium. A subpopulation of EECs expresses Piezo2 and functionally resembles the skin’s touch sensors, called Merkel cells.

CCT2 Promotes Prostate Cancer Progression Through EIF3F‐Dependent Stabilization of FASN

Advanced Science, EarlyView.
ABSTRACT Prostate cancer (PCa) is increasingly recognized to be driven by dysregulated lipid metabolism. Although fatty acid synthase (FASN) is highly expressed in PCa, the mechanisms governing FASN protein stability and its functional integration into oncogenic lipid metabolism remain poorly defined.

A Comparative immunohistochemical analysis of epithelial–mesenchymal transition biomarkers in odontogenic keratocyst, dentigerous cyst, and radicular cyst

Dental Research Journal
Background: Odontogenic keratocyst (OKC) is one of the common odontogenic cysts with aggressive clinical behavior and a high recurrence rate. Epithelial–mesenchymal transition (EMT) is a process, in which the epithelial cell loses its epithelial ...

PDIA6–SCD1 Axis Rewires Lipid Metabolism to Drive Gastric Cancer Progression

Advanced Science, EarlyView.
Protein disulfide isomerase A6 (PDIA6) is identified as an oncogenic driver in gastric cancer. PDIA6 directly binds and stabilizes SCD1 by limiting its ubiquitin–proteasome‐mediated degradation, thereby sustaining monounsaturated fatty acid (MUFA)‐enriched lipid homeostasis and lipid metabolic reprogramming.

Surfaceome Reprogramming of Stemsomes Promotes Lung Cancer Targeting via Potentiated Receptor–Ligand Interactions

Advanced Science, EarlyView.
This study presents a surfaceome‐reprogramming strategy for mutation‐independent lung cancer therapy by repurposing dexamethasone to prime mesenchymal stem cell‐derived nanovesicles. The engineered vesicles leverage multi‐valent interactions mediated by upregulated adhesion proteins, EPHA2, and NOTCH3.

HIV-associated penile anaerobes disrupt epithelial barrier integrity.

PLoS Pathogens
Specific anaerobic taxa within the penile microbiome-the Bacteria Associated with Seroconversion, Inflammation and Immune Cells (BASIC) species-enhance HIV-1 susceptibility, in part by recruiting susceptible cells to the inner foreskin.

Human Urine Stem Cells Alleviate Pulmonary Fibrosis via Inhibiting Macrophage‐Myofibroblast Transition

Advanced Science, EarlyView.
Therapeutic role and mechanism of human urine stem cells (hUSCs) in pulmonary fibrosis. hUSCs alleviated pulmonary fibrosis by selectively inhibiting macrophage‐myofibroblast transition (MMT) in two ways: on one hand, hUSCs inhibited mitochondrial reactive oxygen species (mtROS) production and apoptosis/senescence of epithelial cells in pulmonary ...
