Neuroblastoma is the most prevalent extracranial solid tumor among children and exhibits remarkable heterogeneity. The methylation of cytosine to form 5-methylcytosine (m5C) is the primary type of modification found in DNA and RNA. The NOL1/NOP2/sun (NSUN) family, specifically NSUN1, is responsible for the methylation process and has been shown to play a key role in cell differentiation and cancer development.

Assessing Wound Healing in Vivo Using a Dual-Function Phosphorescent Probe Sensitive to Tissue Oxygenation and Regenerating Collagen.

ACS Appl Mater Interfaces

January 2025

Institute of Translational Medicine, Faculty of Health Sciences & Ministry of Education Frontiers Science Center for Precision Oncology, University of Macau, Taipa 999078, Macau, China.

Levels of tissue oxygenation and collagen regeneration are critical indicators in the early evaluation of wound healing. Traditionally, these factors have been assessed using separate instruments and different methodologies. Here, we adopt the spatially averaged phosphorescence lifetime approach using Re-diimine complexes (Re-probe) to enable simultaneous quantification of these two critical factors in healing wounds.

pERK transition-induced directional mode switching promotes epithelial tumor cell migration.

Proc Natl Acad Sci U S A

Shenzhen Key Laboratory of Metabolism and Cardiovascular Homeostasis, Shenzhen University Medical School, Shenzhen University, Shenzhen, Guangdong 518055, China.

Increasing evidence suggests that tumor cells exhibit extreme plasticity in migration modes in order to adapt to microenvironments. However, the underlying mechanism for governing the migration mode switching is still unclear. Here, we revealed that epithelial tumor cells could develop a stable directional mode driven by hyperactivated ERK activity.

Palmitoylation acts as a checkpoint for MAVS aggregation to promote antiviral innate immune responses.

J Clin Invest

December 2024

MOE Key Laboratory of Gene Function and Regulation, Guangdong Province Key Laboratory of Pharmaceutical Functional Genes, State Key Laboratory of Biocontrol, Innovation Center of the Sixth Affiliated Hospital, School of Life Sciences of Sun Yat-sen University, Guangzhou, Guangdong, China.

Upon RNA virus infection, the signaling adaptor MAVS forms functional prion-like aggregates on the mitochondrial outer membrane, which serve as a central hub that links virus recognition to downstream antiviral innate immune responses. Multiple mechanisms regulating MAVS activation have been revealed; however, the checkpoint governing MAVS aggregation remains elusive. Here, we demonstrated that the palmitoylation of MAVS at cysteine 79 (C79), which is catalyzed mainly by the palmitoyl S-acyltransferase ZDHHC12, was essential for MAVS aggregation and antiviral innate immunity upon viral infection in macrophages.

Department of Gastroenterology, Guangzhou Women and Children's Medical Center, Guangzhou Medical University, Guangzhou, China.

Article Synopsis
  • Gastric intestinal metaplasia is commonly observed in patients with bacterial infection, and rabeprazole is the first-line treatment used to address this condition.
  • The study uses various scientific techniques to demonstrate that rabeprazole promotes ferroptosis, a form of cell death, which helps reduce the expression of proteins associated with gastric intestinal metaplasia, namely CDX2 and MUC2.
  • The mechanism involves the suppression of CREB signaling, leading to decreased GPX4 levels, indicating that targeting ferroptosis could be an effective approach to manage gastric intestinal metaplasia in infected patients.

  • Breast cancer patients show elevated serum levels of reactive oxygen species (ROS), which may impact their endometrial health, but the specific influence of tumor-derived ROS on endometrial function remains uncertain.
  • A study involving both breast cancer patients and a mouse model revealed that endometrial thickness was reduced in tumor-bearing subjects, indicating potential damage caused by cancer-related factors.
  • Vitamin C demonstrated a protective effect on the endometrium by reducing oxidative stress and fibrosis, suggesting it could be a therapeutic option for preserving fertility in younger women diagnosed with breast cancer.

Article Synopsis
  • CHIP (Carboxy-terminus of Hsc70-interacting protein) is an E3 ligase that helps regulate protein stability and plays a crucial role in reducing damage from acute kidney injury (AKI), especially related to cisplatin treatment.
  • In cisplatin-induced AKI, CHIP levels decrease, leading to increased oxidative stress and cell death in renal proximal tubular cells.
  • The study shows that CHIP promotes the degradation of NUR77, a protein that contributes to apoptosis, thus suggesting a protective mechanism against kidney damage caused by cisplatin.

Guangdong Province Key Laboratory of Pharmaceutical Functional Genes, MOE Key Laboratory of Gene Function and Regulation, State Key Laboratory of Biocontrol, School of Life Sciences, Sun Yat-sen University, Guangzhou, China.

ER-phagy, a selective form of autophagic degradation of endoplasmic reticulum (ER) fragments, plays an essential role in governing ER homeostasis. Dysregulation of ER-phagy is associated with the unfolded protein response (UPR), which is a major clue for evoking inflammatory diseases. However, the molecular mechanism underpinning the connection between ER-phagy and disease remains poorly defined.

MCM8-mediated mitophagy protects vascular health in response to nitric oxide signaling in a mouse model of Kawasaki disease.

August 2023

Clinical Biological Resource Bank and Clinical Lab, Guangzhou Institute of Pediatrics, Guangzhou Women and Children's Medical Center, and State Key Laboratory of Respiratory Diseases, Guangzhou Medical University, Guangzhou, China.

Mitophagy is a major quality control pathway that removes unwanted or dysfunctional mitochondria and plays an essential role in vascular health. Here we show that MCM8 expression is significantly decreased in children with Kawasaki disease (KD) who developed coronary artery aneurysms. Mechanistically, we discovered that nitric oxide signaling promotes TRIM21-mediated MCM8 ubiquitination, which disrupts its interaction with MCM9 and promotes its cytosolic export.
