USP7 depletion potentiates HIF2α degradation and inhibits clear cell renal cell carcinoma progression.

Cell Death Dis

October 2024

The First Affiliated Hospital of Xi'an Jiaotong University, Center for Precision Cancer Medicine, MED-X Institute, 710000, Xi'an, China.

Clear cell renal cell carcinoma (ccRCC) is characterized by Von Hippel Lindau (VHL) gene loss of function mutation, which leads to the accumulation of hypoxia-inducible factor 2α (HIF2α). HIF2α has been well-established as one of the major oncogenic drivers of ccRCC, however, its therapeutic targeting remains a challenge. Through an analysis of proteomic data from ccRCCs and adjacent non-tumor tissues, we herein revealed that Ubiquitin-Specific Peptidase 7 (USP7) was upregulated in tumor tissues, and its depletion by inhibitors or shRNAs caused significant suppression of tumor progression in vitro and in vivo.

Article Synopsis
  • Metabolic dysfunction-associated steatotic liver disease (MASLD) is a common chronic liver condition, and the study investigates how the weight-adjusted waist index (WWI) correlates with mortality rates in affected individuals, compared to the traditional BMI metric.
  • The research used data from adults with MASLD between 1999-2018, analyzing their waist circumference and body weight to assess WWI and its impact on both all-cause and cardiovascular disease mortality.
  • Results showed that higher WWI is linked to an increased risk of mortality even after adjusting for BMI, suggesting that WWI is a more accurate predictor of health risks in MASLD patients than BMI alone.

Near-Infrared Activatable Copper Nanoplatforms Synergize with the 5-Azacytidine Prodrug to Potentiate Cuproptosis.

Angew Chem Int Ed Engl

December 2024

Department of Cardiology, Zhongnan Hospital of Wuhan University, School of Pharmaceutical Sciences, Wuhan University, Wuhan, 430071, China.

Cuproptosis, a newly discovered cell death modality, is gaining recognition for its crucial role in antitumor therapy. Here, we demonstrated that Ferredoxin 1 (FDX1), a key gene involved in cuproptosis, is negatively correlated with malignancy and T-cell exhaustion in head and neck squamous cell carcinoma (HNSCC). Based on these findings, we developed near-infrared (NIR) light-controlled nanoparticles (NPs), CuD@PM, which can selectively deliver copper to HNSCC cells and induce cuproptosis in the presence of microneedles loaded with triacetylated azacitidine (TAc-AzaC) and 808 nm laser irradiation.
