A trinity STING-activating nanoparticle harnesses cancer cell STING machinery for enhanced immunotherapy.

The cGAS-STING axis is a promising therapeutic target against cancer. However, most activators require STING signaling in the host, especially within antigen-presenting cells, which are rare in a cold tumor microenvironment. The cGAS-STING cascade is also present within cancer cells but with suppressed activity.

Physiologically Based Pharmacokinetic Modeling to Assess Ritonavir-Digoxin Interactions and Recommendations for Co-Administration Regimens.

Background: Digoxin is a commonly used cardiac glycoside drug in clinical practice, primarily transported by P-glycoprotein (P-gp) and susceptible to the influence of P-gp inhibitors/inducers. Concurrent administration of ritonavir and digoxin may significantly increase the plasma concentration of digoxin. Due to the narrow therapeutic window of digoxin, combined use may lead to severe toxic effects.

In this review, we introduce the definition of cuproptosis and provide a comprehensive discussion of the mechanisms of cuproptosis.

[Cisplatin promotes TNF-α autocrine to trigger RIP1/RIP3/MLKL-dependent necroptosis of human head and neck squamous cell carcinoma cells].

Objective: To investigate whether cisplatin induces tumor necrosis factor-α (TNF-α) secretion in human head and neck squamous cell carcinoma (HNSCC) cells to trigger RIP1/RIP3/MLKL-dependent necroptosis of the cells.

Methods: HNSCC cell lines HN4 and SCC4 treated with cisplatin (CDDP) or the combined treatment with CDDP and z-VAD-fmk (a caspase inhibitor) or Nec-1 (a necroptosis inhibitor) for 24 h were examined for changes in cell viability using CCK8 assay and expressions of caspase-8 and necroptosis pathway proteins (RIP1/RIP3/MLKL) using Western blotting. The changes in migration of the cells were assessed with cell scratch assay, and the expressions of epithelial-mesenchymal transition (EMT) marker proteins N-cadherin, vimentin, and E-cadherin as well as the expressions of NF-κB (p65) and TNF-α were detected with Western blotting.

β-Hydroxybutyrate and Citrate Synthase as Potential Diagnostic Biomarkers in Aging-Related Atrial Fibrillation.

The incidence of atrial fibrillation (AF) increases with age; however, the precise mechanisms by which aging elevates AF risk and the effective biomarkers for managing AF in elderly patients remain unclear. We analyzed plasma samples from 100 elderly AF patients, 100 young and 100 elderly patients without atrial fibrillation (NAF), along with left atrial tissues obtained from both AF and NAF patients following valve replacement. Our findings indicate reduced levels of β-OHB and citrate synthase (CS) activity in elderly AF patients compared to their NAF counterparts.

A dual-STING-activating nanosystem expands cancer immunotherapeutic temporal window.

Stimulator of interferon genes (STING) is a promising antitumor target via bridging innate and adaptive immunity, yet the transient nature of immune signal transduction renders small-molecule agonists susceptible to short time effectiveness. Here, we report a dual-STING-activating micelle system (D-SAM) to dynamically program STING kinetics. Mechanistically, the natural ligand cGAMP encapsulated in D-SAM initiates STING signaling, while the pH-sensitive polymeric agonist PC7A disassembled from micelle shell buffers lysosomal protons and retards STING degradation.
