Diabetic foot ulcer (DFU) is a common but devastating complication of diabetes mellitus and might ultimately lead to amputation. Elucidating the regulatory mechanism of wound healing in DFU is quite important for developing DFU management strategies. Here, we show, mecenchymal stem cell (MSC)-derived exosomes promoted the proliferation, migration and angiogenesis of high glucose-treated endothelial cells and reduced cell apoptosis.

Osteosarcoma tissues demonstrated elevated expression of proteins (FDX1 and DLAT) integral to cuproptosis in our preliminary study, indicating the potential effectiveness of anti-tumor strategies predicated on this process. Nevertheless, the overexpression of copper export proteins and the challenge of copper ion penetration may contribute to insufficient local copper ion concentration for inducing cuproptosis. Herein, we engineered a biomimetic copper-elesclomol-polyphenol network for the efficient delivery of copper ions and the copper ionophore elesclomol.

Programmed cell death represents a precisely regulated and active cellular demise, governed by a complex network of specific genes and proteins. The identification of multiple forms of programmed cell death has significantly advanced the understanding of its intricate mechanisms, as demonstrated in recent studies. A thorough grasp of these processes is essential across various biological disciplines and in the study of diseases.

  • PD-1 checkpoint blockade has improved cancer treatment, but its effectiveness varies among patients, highlighting the need to understand how PD-L1 expression affects treatment success.
  • Researchers used CRISPR/Cas9 screening to identify key regulators of PD-L1 in non-small cell lung cancer (NSCLC), focusing on the transcription factor CEBPB and its isoform LIP, and their impact on PD-L1 transcription.
  • The study found that LIP suppresses PD-L1 expression in NSCLC by forming a complex that decreases PD-L1 transcription, suggesting that targeting LIP could improve the effectiveness of immunotherapy.

Aims: For displaced femoral neck fractures (FNFs) in geriatric patients, there remains uncertainty regarding the effect of total hip arthroplasty (THA) compared with hemiarthroplasty (HA) in the guidelines. We aimed to compare 90-day surgical readmission, in-hospital complications, and charges between THA and HA in these patients.

Methods: The Hospital Quality Monitoring System was queried from 1 January 2013 to 31 December 2019 for displaced FNFs in geriatric patients treated with THA or HA.
