More and more evidence suggested that necroptosis plays a crucial role in the pathogenesis and progression of sepsis. This study aimed to elucidate the biological function and clinical significance of necroptosis in sepsis, and identify new potential biomarkers to improve the diagnosis and treatment of sepsis. Firstly, we identified 40 differentially expressed necroptosis related genes (DENRGs). Subsequently, a protein interaction (PPI) network of 40 DENRGs was constructed. Based on the key NRGs in the PPI network, the LASSO algorithm was used to screen eight diagnostic-related NRGs in sepsis, and a diagnostic model and risk score were constructed. The ROC analysis results indicated that the eight NRGs diagnostic model has good diagnostic performance (AUC = 0.955). There is a significant difference in risks core between normal samples and sepsis patients. The results of immune infiltration analysis showed that eight diagnostic-related NRGs were significantly correlated with multiple immune cells. Given the clinical significance of necroptosis in sepsis, we identified two molecular subtypes of sepsis based on eight NRGs. The necroptosis score of subtype 1 is significantly lower than that of subtype 2, while the immune score of subtype 1 is significantly higher than that of subtype 2. In summary, we developed and validated a diagnostic model and risk score based on eight NRGs, and identified two completely different subtypes associated with sepsis. Our research may provide new insights into the mechanisms of necroptosis in sepsis and the identification of potential biomarkers.</p>","PeriodicalId":465,"journal":{"name":"Applied Biochemistry and Biotechnology","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, optimal conditions in the integrated process, fermentation and extraction, were determined by response surface methodology for the highest polyphenol recovery from WP. The post-process extract showed a dramatic improvement in polyphenol content with an increase in various phenolic compounds determined by UHPLC-MS/MS and a significant decrease in cytotoxicity. In addition, two limitations of polyphenols, low stability and bioaccessibility, were significantly improved. Various health potentials of WP were also enhanced: antioxidant (radical scavenging and ferric reduction), anti-inflammatory (inhibition of heat-induced hemolysis, protein denaturation and protease), selectively antibacterial (anti-growth, anti-survival and anti-biofilm for pathogenic bacteria), prebiotic (promotion of probiotic growth and biofilm formation), anti-diabetic (α-glucosidase and α-amylase inhibition), and anti-melanogenic (tyrosinase inhibition).

To elucidate the molecular mechanisms underlying these effects, proteomics analysis was performed following treatment with 50 µmol/L Tan IIA, focusing on alterations in Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Additionally, in vitro evaluations such as glucose uptake, lactate production, and adenosine triphosphate (ATP) synthesis were employed to validate the alterations in glycolytic activity observed in anaerobic cells treated with Tan IIA. Under anaerobic conditions, Tan IIA enhanced the inhibitory effect on the proliferation of MGC803 cells.

Characterization demonstrated distinct properties; Ag-NPs, Cu-NPs, and Ag-Cu bimetallic NPs exhibited surface plasmon resonance peaks at 425 nm, 555 nm, and 525 nm, respectively, and crystallite sizes of 21.42 nm, 21.40 nm, and 26.29 nm as confirmed by X-ray diffraction.

Catalytic activity tests showed Ag-Cu bimetallic NPs achieved 95% degradation of methylene blue dye, highlighting their potential in environmental remediation. Antibacterial assays demonstrated that Ag-NPs exhibited the highest inhibition zones against Bacillus subtilis (27.0 mm) and Escherichia coli (27.67 mm), while Cu-NPs were effective against Klebsiella pneumoniae at higher concentrations.

Therefore, in comparison to CSG 8962 (check for salinity tolerance), an experiment on nine chickpea genotypes with different background (BG 1103, DCP 92-3, S7, ICCV 10, BG 256, KWR 108, JG 16, K 850, and ICC 4463) was conducted under medium salt stress of EC<sub>iw</sub> ~ 6 dS m<sup>-1</sup> and high salt stress of 9 dS m<sup>-1</sup> to evaluate their salt tolerance potential. Different morphological, physiological, biochemical, and molecular traits were studied to characterize these genotypes. It was also noted that growth of all the genotypes was affected by salinity, but more reduction was shown by the genotypes BG 256, DCP 92-3, and ICC 4463. Irrigation water loaded with salts disrupted the water relations as displayed by the reducing values of RWC, water potential, and osmotic potential. Chlorophyll content, when compared with control, reduced in the range of 7.06 to 28.93% at moderate salinity level (EC<sub>iw</sub> ~ 6 dS m<sup>-1</sup>) and 23.71 to 55.83% at higher salinity level (EC<sub>iw</sub> ~ 9 dS m<sup>-1</sup>). S7, ICCV 10, KWR 108, and CSG 8962 (salt-tolerant check) maintained optimum gas exchange traits, i.e., photosynthetic rate, stomatal conductance, and transpiration rate with increasing salinity and osmoregulatory compounds, imino acid proline, and total soluble sugars were also higher in these genotypes.

The functional profiling of metagenome indicated the abundance of genes involved in degradation of polymeric compounds such as carbohydrates, lipids, and proteins. The relative abundance of arginine and proline metabolisms increased during the thermophilic stage. Whereas the relative abundance of genes involved in fatty acid, tryptophan, galactose, and propanoate metabolisms declined. Similarly, the CAZyme tool predicted that the genes encoding for glycoside hydrolase (GH) families were higher during the mesophilic and thermophilic stages of composting.
