Article Abstract
PYCARD is a protein engaged in inflammation, pyroptosis, and apoptosis. However, the function of PYCARD in human cancers remains unclear. The objective of our study was to explore PYCARD expression and prognostic value in human cancers. Public databases were used to assess PYCARD expression and prognostic value. The TISIDB database was used to explore the associations between PYCARD expression and different immune subtypes. The correlations between PYCARD expression and ICP genes, MMR genes, MSI, and TMB were also investigated. The immunotherapy response was assessed using the TIDE database. Single-cell RNA databases evaluated the PYCARD expression of immune cells. External datasets and immunohistochemical staining were conducted to validate PYCARD expression and prognostic value. The results showed that PYCARD expression varied in several cancers and was associated with prognosis, immune-related genes, published biomarkers, and immunotherapy response. Of note, PYCARD expression was upregulated in renal cancers with high diagnostic ability. Upregulation of PYCARD was correlated with worse prognosis in KIRC and external validation cohorts. In conclusion, PYCARD demonstrated strong correlations with prognosis, immune response, and disease progression in pan-cancer analysis. In ccRCC, PYCARD might serve as a biomarker for diagnosis and therapeutic target-boosting immunotherapy response.

Lipid nanoparticle-delivered intrabodies for inhibiting necroptosis and pyroptosis.

Intrabodies are intracellularly expressed high-affinity protein binders such as nanobodies and monobodies that offer an alternative approach to small molecules. However, the maturation of intrabody technology into new therapeutic modalities has been limited by the availability of a clinically relevant delivery system enabling sufficiently high levels of protein to be expressed in the cytosol. Here, we use lipid nanoparticle (LNP) systems based on clinically approved formulations for the efficient intracellular delivery of mRNAs encoding for intrabodies targeting mixed lineage kinase domain-like pseudokinase (MLKL) and apoptosis-associated speck-like protein containing a CARD (ASC), key mediators of the necrotic cell death modalities, necroptosis and pyroptosis, respectively.

Alzheimer's disease (AD) stands as the primary reason for aging-related dementia and is swiftly becoming recognized as one of the century's most expensive, fatal, and burdensome illnesses, which calls for more convenient diagnostic methods. Increasing studies indicate the involvement of pyroptosis in the advancement of AD. Yet, the precise role of molecules associated with pyroptosis in the diagnosis of Alzheimer's disease remains unexplored.

Numerous investigations indicate that cyclosporine A (CsA) significantly influences the prevention or progression of Alzheimer's disease (AD) through various mechanisms. The precise pathways by which CsA, an inhibitor of calcineurin (CN) and peptidyl-prolyl isomerase A (PPIA), operates remain incompletely elucidated. In this study, we explored the effects of CsA, a widely utilized immunosuppressive agent, on the gene expression of various factors related to inflammation, cell adhesion, intercellular communication, and apoptosis in SH-SY5Y cells.

Systemic lupus erythematosus (SLE) is closely associated with neutrophils and pyroptosis, but the pyroptosis related genes (PRGs) with neutrophils in SLE have been less studied. Based on public databases, key genes associated with neutrophil pyroptosis in SLE were identified through immune infiltration analysis and differential analysis. Subsequently, three machine learning algorithms were utilised to derive biomarkers.

Objectives: This study was designed to investigate the gastroprotective effects of 'Chachi' polysaccharide (CRP) against alcohol-induced gastric ulcers (GUs) and to elucidate its underlying mechanisms.
Methods: CRP was extracted, purified, and structurally characterized. BALB/c mice (50/250 mg/kg CRP) and GES-1 cells (1 mg/mL CRP) were subjected to alcohol-induced injury.
