RAB25/GCN1 Signaling Promotes ER Stress to Mediate Alcohol-associated Liver Disease Progression.

Clin Mol Hepatol

September 2025

Department of Endoscopy, Sun Yat-sen University Cancer Center, State Key Laboratory of Oncology in South China, Guangdong Provincial Clinical Research Center for Cancer, Guangzhou, China.

Background/aims: Endoplasmic reticulum (ER) stress in hepatocytes plays a causative role in alcohol-associated liver disease (ALD). The incomplete inhibition of ER stress by targeting canonical ER stress sensor proteins suggests the existence of noncanonical ER stress pathways in ALD pathology. This study aimed to delineate the role of RAB25 in ALD and its regulatory mechanism in noncanonical ER stress pathways.

Phase separation of ERCC6L2-CtIP regulates the extent of DNA end resection.

Nat Cell Biol

September 2025

State Key Laboratory of Oncology in South China, Guangdong Provincial Clinical Research Center for Cancer, Sun Yat-sen University Cancer Center, Guangzhou, China.

The ataxia telangiectasia mutated (ATM) kinase orchestrates the early stages of DNA double-strand break repair by promoting hyperphosphorylation of CtIP, a key step in the initiation of DNA end resection. However, the regulatory mechanisms controlling resection extent remain incompletely understood. Here we identify ERCC6L2 as a key regulator of DNA end resection in response to ATM inhibition.

RNF217-KEAP1-NRF2 feedback loop confers therapeutic resistance by inhibiting ferroptosis in esophageal squamous cell carcinoma.

Drug Resist Updat

August 2025

State Key Laboratory of Oncology in South China, Collaborative Innovation Centre for Cancer Medicine, Guangdong Provincial Clinical Research Center for Cancer, Guangdong Esophageal Cancer Institute, Guangzhou, China; Department of Radiation Oncology, Sun Yat-sen University Cancer Center, Guangzhou,

Resistance to chemoradiotherapy is a crucial factor limiting the efficacy of therapy and prognosis of esophageal cancer. It is necessary to elucidate the key genes and regulatory mechanisms responsible for therapeutic resistance in esophageal squamous cell carcinoma (ESCC). In this study, we found a relationship between ferroptosis and therapeutic sensitivity in ESCC and identified the ring finger protein 217 (RNF217) as a new regulator of ferroptosis associated with resistance to chemoradiotherapy in ESCC.

Electronic address: majun2@

The Chinese Society for Therapeutic Radiology Oncology, the Chinese Anti-Cancer Association, the Chinese Society of Clinical Oncology, the Head and Neck Cancer International Group, the European Society for Radiotherapy and Oncology, and the American Society for Radiation Oncology collaboratively developed evidence-based guidelines and a comprehensive contouring atlas for neck target volume delineation in nasopharyngeal carcinoma. These guidelines address five key challenges in modern radiotherapy practice: margin design of clinical target volume; nodal target volume delineation after induction chemotherapy; delineation of equivocal nodes evident on imaging; low-risk clinical target volume delineation based on regional stepwise extension patterns; and modifications for anatomical boundaries of lymphatic areas. Developed through a rigorous systematic review and expert appraisal process by a panel of 50 international, multidisciplinary members from 17 countries and regions, these guidelines incorporate the latest advances in nasopharyngeal carcinoma diagnosis and treatment.

Cancer progression is characterized by dysregulated G1/S phase transition mediated by CDK4/6-dependent Rb protein phosphorylation. Although CDK4/6 degraders show encouraging anti-tumor efficacy, it is highly desired to develop strategies to spatiotemporally control the release of active CDK4/6 degraders to further reduce adverse effects. In this study, we employ an optochemical strategy for CDK4/6 degradation by caging the CRBN ligand with a photoremovable protecting group.

Breast cancer therapy confronts dual challenges of metabolic plasticity-driven drug resistance and immunosuppression. To address this, we developed DCP-TPP, a therapeutic nanoplatform that integrates dysregulation of copper homeostasis and lipid metabolism for precise breast cancer therapy. Leveraging the overexpression of cluster of differentiation 36 (CD36) in breast cancer cells, DCP-TPP employs fatty acid camouflage (PCM) to deliver disulfiram (DSF) and photothermal CuBiS to cancer cells and features triphenylphosphonium (TPP) modification for targeted mitochondrial drug delivery.

Hospital of Stomatology, Guanghua School of Stomatology, Guangdong Provincial Key Laboratory of Stomatology, Sun Yat-Sen University, Guangzhou, China. Electronic address:

Accurate instance segmentation of tooth and pulp from cone-beam computed tomography (CBCT) images is essential but highly challenging due to the pulp's small structures and indistinct boundaries. To address these critical challenges, we propose TIPs designed for Tooth Instance and Pulp segmentation. TIPs initially employs a backbone model to segment a binary mask of the tooth from CBCT images, which is then utilized to derive position prior of the tooth and shape prior of the pulp.

BMC Cancer

August 2025

Department of Medical Oncology, State Key Laboratory of Oncology in South China, Guangdong Provincial Clinical Research Center for Cancer, Collaborative Innovation Center for Cancer Medicine, Sun Yat-Sen University Cancer Center, Guangzhou, China.

Background: Baseline tumor burden (TB), measured radiographically, has emerged as a potential biomarker for stratifying survival outcomes with immune checkpoint inhibitors (ICI) across solid tumors. However, the predictive value for ICI plus chemotherapy (chemoimmunotherapy) in NSCLC has not been confirmed with large cohorts that include a chemotherapy-only control group.

Methods: This post hoc analysis utilized data from ORIENT-11 trial, a phase III, randomized clinical trial of advanced NSCLC patients who were administered with either chemoimmunotherapy or chemotherapy alone.

Background: Noninvasive biomarkers that capture the longitudinal multiregional tumour burden in patients with breast cancer may improve the assessment of residual nodal disease and guide axillary surgery. Additionally, a significant barrier to the clinical translation of the current data-driven deep learning model is the lack of interpretability. This study aims to develop and validate an information shared-private (iShape) model to predict axillary pathological complete response in patients with axillary lymph node (ALN)-positive breast cancer receiving neoadjuvant therapy (NAT) by learning common and specific image representations from longitudinal primary tumour and ALN ultrasound images.

Dynamic Prognostic Models for Colorectal Cancer With Liver Metastases.

JAMA Netw Open

August 2025

Department of Hepatobiliary Surgery, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Importance: Current prognostic models for colorectal liver metastases (CRLM) primarily incorporate clinicopathologic features assessed at a single time point, resulting in a static risk assessment for individuals. Given that tumor progression is a dynamic process, especially for patients with CRLM, and patients' data are continuously collected during the follow-up visits, dynamic prediction is a natural model for risk assessments via reflecting the latest prognosis, whenever new marker measurements are available.

Objective: To develop CRLM prognostic models and a clinical web-based tool to facilitate dynamic predictions.
