Esophageal xanthoma: presence of M2 macrophages suggests association with late inflammatory and reparative processes

open access: yesOpen Medicine, 2017
Esophageal xanthoma is a rare lesion which is an asymptomatic small yellowish polyp, and most of the reported cases were solitary lesion. Histologically, aggregations of foam cells are found under the papillary hypertrophic squamous epithelium and the ...

POLE Deficiency Exacerbates Diesel Engine Exhaust‐Induced Genomic Instability and Malignant Transformation of Bronchial Epithelial Cells

open access: yesAdvanced Science, EarlyView.
This study establishes a diesel engine exhaust (DEE)‐induced malignant transformation model in bronchial epithelial cells. Whole genome sequencing(WGS) and RNA‐seq reveal DEE‐induced mutational signatures and gene expression profiles. Mechanistically, DEEaffect polymerase epsilon (POLE) and mismatch repair, driving genomic instability and promoting ...

Targeting Intratumoral Copper Inhibits Tumor Progression via p62‐Mediated EZH2 Degradation and Potentiates Anti‐PD‐1 Immunotherapy in Oral Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
The authors find that by targeting intratumoral copper, they can enhance p62‐mediated ubiquitination of EZH2 at the Ub‐K63 site by suppressing copper binding to SMURF2, an E3 ligase of EZH2, leading to its autophagic degradation. This mechanism suppressed OSCC progression and potentiated anti‐PD‐1 immunotherapy, highlighting a potential new therapeutic

Single‐Cell and Spatial Transcriptomic Profiling of Penile Squamous Cell Carcinoma Reveals Dynamics of Tumor Differentiation and Immune Microenvironment

open access: yesAdvanced Science, EarlyView.
This study uses single‐nucleus RNA sequencing and spatial transcriptomics to investigate penile squamous cell carcinoma (PSCC). It reveals that PSCC tumor cells mimic normal penile epithelium differentiation, independent of HPV status. The Tum_1 subtype shows basal stem‐like characteristics and promotes invasiveness. HPV‐positive basal stem‐like tumors

QSOX2‐Mediated Disulfide Bond Modification Enhances Tumor Stemness and Chemoresistance by Activating TSC2/mTOR/c‐Myc Feedback Loop in Esophageal Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
High QSOX2 enhances stemness, drug resistance, and metastasis of ESCC cells. QSOX2‐mediated disulfide bond modification activates mTOR/c‐Myc signaling. CAFs‐secreted IGF‐1 drives mTOR/c‐Myc/QSOX2 positive feedback loop. Combining Ebselen, rapamycin, and cisplatin induces tumor dormancy in mice.

Kindlin Regulates Mechanosensitive Activation and Adhesion Assembly of Integrin beta6

open access: yesAdvanced Science, EarlyView.
Extracellular matrix compliance plays a critical role in the regulation of integrin‐mediated adhesion and cell motility. Here, it is reported that strengthening the kindlin2‐integrin β6 interaction overcomes the dependence on extracellular substrate stiffness and promotes integrin β6‐mediated cell migration.

A Super‐Enhancer‐Driven Transcriptional Regulatory Circuit Underlying Abiraterone Resistance in Castration‐Resistant Prostate Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies a super‐enhancer‐driven transcriptional regulatory circuit comprising BCL6, SMAD3, and NFIB that cooperate to drive cholesterol synthesis via SREBF2/HMGCR/FDFT1 activation and regulate CDK2/CCND3 for cell cycle control. Targeting this circuit with BI‐3802 or downstream inhibitors (Fatostatin/Lovastatin) overcomes abiraterone ...
