Abstract
Purpose Sepsis-induced lung injury (SLI) is a serious complication of sepsis. PANoptosis, a novel form of inflammatory programmed cell death that is not yet to be fully investigated in SLI. Our research aims to screen and validate the signature genes of PANoptosis in SLI by bioinformatics and in vivo experiment. Methods SLI-related datasets were downloaded from NCBI Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) of SLI were identified and intersected with the PANoptosis gene set to obtain DEGs related to PANoptosis (SPAN_DEGs). Then, Protein-Protein Interaction (PPI) network and functional enrichment analysis were conducted based on SPAN_DEGs. SVM-REF, LASSO and RandomForest three algorithms were combined to identify the signature genes. The Nomogram and ROC curves were performed to predict diagnostic value. Immune infiltration analysis, correlation analysis and differential expression analysis were used to explore the immunological characterization, correlation and expression levels of the signature genes. Finally, H&E staining and qRT-PCR were conducted for further verification in vivo experiment. Results Twenty-four SPAN_DEGs were identified by intersecting 675 DEGs with the 277 PANoptosis genes. Four signature genes (CD14, GSDMD, IL1β, and FAS) were identified by three machine learning algorithms, which were highly expressed in the SLI group, and had high diagnostic value in the diagnostic model. Moreover, immune infiltration analysis showed that most immune cells and immune-related functions were higher in the SLI group than those in the control group and were closely associated with the signature genes. Finally, it was confirmed that the cecum ligation and puncture (CLP) group mice showed significant pathological damage in lung tissues, and the mRNA expression levels of CD14, IL1β, and FAS were significantly higher than the sham group. Conclusion CD14, FAS, and IL1β may be the signature genes in PANoptosis to drive the progression of SLI and involved in regulating immune processes.

Abstract
Genetic variation remains a topic of great interest due to its potential as a risk factor for various diseases. Interactions between genes contribute to diverse phenotypes in response to factors such as infection. The impact of genetic background on susceptibility and clinical outcomes, particularly in neonatal sepsis, has gained recognition. The variability in sepsis susceptibility and outcomes can be attributed to the genetic diversity in coding regions and regulatory elements of genes related to innate immune response. Recent advances in genomics and technology have shed light on genetic polymorphisms among humans, often represented by single-nucleotide polymorphisms (SNPs). These SNPs encode proteins crucial for recognizing and responding to pathogenic bacteria, including Toll-like receptor 4, CD14, tumor necrosis factor-alpha, as well as interleukin-1-10. This literature review specifically discusses the involvement of genetic polymorphism during the pathogenesis stage of sepsis, with an emphasis on previous research findings in neonatal sepsis cases, aiming to discuss the implications of polymorphism in sepsis susceptibility and outcomes.

Abstract
Sepsis, an inflammation-related clinical syndrome, is characterized by disrupted immune homeostasis accompanied by infection and multiple organ dysfunction as determined by the Sequential Organ Failure Assessment (SOFA). Substantial evidence has recently suggested that lncRNAs orchestrate various biological processes in diseases, and lncRNAs play special roles in the diagnosis and management of sepsis. To date, very few reviews have provided clear and comprehensive clues to demonstrate the roles of lncRNAs in the pathogenesis of sepsis. Based on previously published studies, in this review, we summarize the different functions of lncRNAs in sepsis-induced cellular disorders and sepsis-induced organ failure to show the potential roles of lncRNAs in the diagnosis and management of sepsis. We further depict the function of some lncRNAs known to be pivotal regulators in the pathogenesis of sepsis to discuss the underlying molecular events. Additionally, we list and discuss several hotspots in research on lncRNAs, which may be conducive to future lncRNA-targeted therapeutic approaches for sepsis treatment.

Abstract
Summary of background data
The association between tumor necrosis factor α (TNFα) -308G/A polymorphism and susceptibility to posttraumatic sepsis has been studied extensively. But the results have not remained very clear.
Purpose
We carried out this meta-analysis to explore the influence of TNF on susceptibility to posttraumatic sepsis.
Methods
Relevant studies were identified from PubMed, Web of Science, Embase, and China National Knowledge Internet without language limitation, following the inclusion and exclusion criteria. Statistical analyses were implemented with the STATA 12.0 statistical software.
Results
Seven case-control studies were included in the meta-analyses on the association of TNFα -308 G/A genetic polymorphism and risk of posttraumatic sepsis. TNFα -308 G/A genetic polymorphism was significantly associated with susceptibility to posttraumatic sepsis in the dominant model [odds ratio (OR), 2.17; 95% confidence interval (95% CI), 1.19–3.95; P = 0.011] and allelic model (OR, 1.72; 95% CI, 1.23–2.39; P = 0.001), but not in the heterozygous model (OR, 1.38; 95% CI, 0.58–3.39; P = 0.489). There was no significant publication bias for these 3 models. However, marked heterogeneity existed in the dominant model (I2 = 68.9%, P = 0.004) and the heterozygous model (I2 = 68.9%, P = 0.022).
Conclusions
TNF -308 G/A genetic polymorphism may have an influence on susceptibility to posttraumatic sepsis. Further studies with large sample sizes and well-designed studies are needed to confirm these results.

Abstract
Sepsis-related mortality and morbidity are major health care problems worldwide. More effort is required to identify factors associated with adverse outcome. Evaluate the prognostic capacity of tumor necrosis factor (TNF), kidney injury molecule (KIM), and lactate and TNF-α-308 G > A gene polymorphism for prediction of 28 days-intensive care unit (ICU) mortality. TNF-α-308 G > A single nucleotide polymorphisms was detected by real-time-PCR on 112 had septic shock and 88 were septic. Serum TNF-α and urinary KIM were assessed by enzyme-linked immunosorbent assay. This study included 200 critically ill patients, 125 (62.5%) of them died within 28 days in ICU (nonsurvivors). Frequencies of TNF-308 G > A was (70.7) GG, (28) GA and (1.3) AA in survivors versus (85.6) GG, (12) GA and (2.4) AA for nonsurvivors, revealed significant association with ICU mortality but not sepsis severity (p = 0.15) or sepsis-induced acute kidney injury (AKI). In contrast, urinary KIM-1 revealed significant association with sepsis severity (p = 0.036) and AKI (p = 0.0001), but not 28-days ICU mortality. The relative risk of death in patients with GG genotype was 2.5 mainly in ICU younger male patients (odds ratios 24 and 4.9, p = 0.001). The genotype GG and GA were significantly associated with [increased urinary KIM-1 (0.29 ± 0.1) (p = 0.0001), terminal creatinine (1.67 ± 0.8) (p = 0.0001)] and [increased terminal urea (109 ± 0.001) (p = 0.001) and basal serum TNF (60 ± 0.001) (p = 0.0001)], respectively. In linear regression analysis, AKI 0.0001 (0.4-0.67), basal serum TNF 0.04 (0.0001-0.04), and TNF-308 GG 0.007 (0.05-0.33) were associated with 28 days ICU mortality [p value (95% confidence interval)]. The same results were observed for initial urea 0.024 (0.0001-0.003) and lack of diuretic usage 0.0001 (0.35-0.7) mainly in septic patients. Major frequency of TNF-308 G > A polymorphism (mainly in young age male patients), AKI and serum TNF were associated with increased risk for 28 days-ICU mortality. Furthermore, sepsis severity was influenced by TNF and urinary KIM-1, which reflects in AKI.

Abstract
Background The goal of the study was to evaluate a potential role for tumor necrosis factor alpha (TNF-α) genetic variability as biomarker in sepsis. In particular, we aimed to determine if single nucleotide polymorphisms (SNPs) of TNF-α gene are associated with sepsis in terms of risk, severity and outcome. Methods We performed a prospective study on 163 adult critically ill septic patients (septic shock 65, sepsis 98, further divided in 40 survivors and 123 deceased) and 232 healthy controls. Genotyping of TNF-α SNPs (-308G/A, -238G/A, -376G/A and +489G/A) was performed for all patients and controls and plasma cytokine levels were measured during the first 24 h after sepsis onset. Results TNF-α +489G/A A-allele carriage was associated with significantly lower risk of developing sepsis and sepsis shock (AA+AG vs GG: OR = 0.53; p = 0.004; 95% CI = 0.34–0.82 and OR = 0.39; p = 0.003; 95% CI = 0.21–0.74, respectively) but not with sepsis-related outcomes. There was no significant association between any of the other TNF-α promoter SNPs, or their haplotype frequencies and sepsis or septic shock risk. Circulating TNF-α levels were higher in septic shock; they were not correlated with SNP genotype distribution; GG homozygosity for each polymorphism was correlated with higher TNF-α levels in septic shock. Conclusions TNF-α +489G/A SNP A-allele carriage may confer protection against sepsis and septic shock development but apparently does not influence sepsis-related mortality. Promoter TNF-α SNPs did not affect transcription and were not associated with distinct sepsis, septic shock risk or outcomes.

The interleukin-27 -964A>G polymorphism enhances sepsis-induced inflammatory responses and confers susceptibility to the development of sepsis.

Abstract
Background Previous studies have identified critical roles of IL-27 in the pathological mechanisms of sepsis, and blockade of IL-27 may be a promising alternative therapy for sepsis. The purpose of this study was to evaluate the clinical relevance of IL-27 genetic polymorphisms in sepsis and to further characterize their effect on IL-27 expression and inflammatory processes following sepsis. Methods A total of 885 septic patients and 1101 healthy controls were enrolled and genotyped for IL-27 genetic variants (rs153109/−964A > G and rs17855750/2905 T > G). Quantitative real-time PCR and enzyme-linked immunosorbent assays were performed to detect IL-27 expression and cytokine production. The effect of the rs153109 polymorphism on IL-27 promoter activity was evaluated using a luciferase reporter assay, and THP-1 cell apoptosis was calculated using an annexin V apoptosis assay. Results No significant differences in the genotype/allele frequencies were observed between patients with sepsis and healthy controls, suggesting that these two IL-27 polymorphisms may not influence susceptibility to sepsis. The -964AA genotype was overrepresented in patients with severe sepsis/septic shock relative to patients with the sepsis subtype, and the A allele was significantly associated with 28-mortality in sepsis. Patients carrying the -964AA genotype exhibited significantly higher expression levels of IL-27 than the GA/GG genotype carriers. The results of an in vitro (lipopolysaccharide (LPS))-stimulated experiment showed that this sepsis-associated high-risk AA genotype significantly increased IL-27 levels and enhanced TNF-α and IL-1β production in the peripheral blood mononuclear cells (PBMCs) upon exposure to LPS in vitro. Furthermore, luciferase reporter assays indicated that the high-risk -964A allele resulted in increased promoter activities compared to the non-risk allele in THP-1 and 293 T cells. Additionally, IL-27 treatment significantly enhanced TNF-α and IL-6 secretion and apoptosis of THP-1 cells upon LPS stimulation. Conclusions These results provided evidence that the IL-27 -964A > G polymorphism functionally enhanced IL-27 expression and promoted sepsis-induced inflammatory responses, which ultimately resulted in promoting the progression of sepsis and poor prognosis.

Haplotypes composed of minor frequency single nucleotide polymorphisms of the TNF gene protect from progression into sepsis: A study using the new sepsis classification. Int J Infect Dis 2017; 67:102-106.

Abstract
OBJECTIVES Several articles have provided conflicting results regarding the role of single nucleotide polymorphisms (SNPs) in the promoter region of the TNF gene in susceptibility to sepsis. Former articles have been based on previous definitions of sepsis. This study investigated the influence of TNF haplotypes on the development of sepsis using the new Sepsis-3 definitions. METHODS DNA was isolated from patients suffering from infection and systemic inflammatory response syndrome. Haplotyping was performed for six SNPs of TNF. The serum levels of tumour necrosis factor alpha (TNF-α) of these patients were measured using an enzyme immunosorbent assay. Patients were classified into infection and sepsis categories using the Sepsis-3 definitions. Associations between the TNF haplotypes and the clinical characteristics and serum TNF-α levels of the patients were examined. RESULTS The most common TNF haplotype h1 was composed of major alleles of the studied SNPs. Carriage of haplotypes composed of minor frequency alleles was associated with a lower risk of developing sepsis (odds ratio 0.41, 95% confidence interval 0.19-0.88, p=0.022), but this did not affect the 28-day outcome. Serum TNF-α levels were significantly higher among patients homozygous for h1 haplotypes who developed sepsis compared to infection (p=0.032); a similar result was not observed for patients carrying other haplotypes. CONCLUSIONS Haplotypes containing minor frequency SNP alleles of TNF protect against the development of sepsis without affecting the outcome.

Abstract
This meta-analysis of 23 eligible articles comprehensively and quantitatively evaluated the effects of tumor necrosis factor-α (TNF-α) rs1800629 and rs361525 polymorphisms on sepsis risk. We found that TNF-α rs1800629 was associated with increased sepsis risk in the overall population in four genetic models, including A vs. G (P<0.001, odds ratio (OR)=1.32), GA vs. GG (P<0.001, OR=1.46), GA+AA vs. GG (P<0.001, OR=1.46), and carrier A vs. carrier G (P<0.001, OR=1.32). Subgroup analyses showed a similar result for Asian patients (all P<0.05, OR>1). TNF-α rs361525 was also associated with increased sepsis risk in Asian patients in the four genetic models (all P<0.05, OR>1). Begg's and Egger's tests excluded large publication bias, and sensitivity analysis indicated stable results. Our results suggest that the G/A genotype of TNF-α rs1800629 and rs361525 increases sepsis risk in an Asian population.

Abstract
Background: The humoral system is activated and various cytokines are released due to infections in tissues and traumatic damage. Nuclear factor-kappa B dimers are encoded by nuclear factor-kappa B genes and regulate transcription of several crucial proteins of inflammation such as tumour necrosis factor-alpha. Aims: To investigate the possible effect of polymorphisms on tumour necrosis factor-alpha serum levels with clinical and prognostic parameters of sepsis by determining the nuclear factor-kappa B-1-94 ins/del ATTG and tumour necrosis factor-alpha (-308 G/A) gene polymorphisms and tumour necrosis factor-alpha serum levels. Study Design: Case-control study. Methods: Seventy-two patients with sepsis and 104 healthy controls were included in the study. In order to determine the polymorphisms of nuclear factor-kappa B-1-94 ins/del ATTG and tumour necrosis factor-alpha (-308 G/A), polymerase chain reaction–restriction fragment length polymorphism analysis was performed and serum tumour necrosis factor-alpha levels were determined using an enzyme-linked immunosorbent assay. Results: We observed no significant differences in tumour necrosis factor-alpha serum levels between the study groups. In the patient group, an increase in the tumour necrosis factor-alpha serum levels in patients carrying the tumour necrosis factor-alpha (-308 G/A) A allele compared to those without the A allele was found to be statistically significant. Additionally, an increase in the tumour necrosis factor-alpha serum levels in patients carrying tumour necrosis factor-alpha (-308 G/A) AA genotype compared with patients carrying the AG or GG genotypes was statistically significant. No significant differences were found in these 2 polymorphisms between the patient and control groups (p>0.05). Conclusion: Our results showed the AA genotype and the A allele of the tumour necrosis factor-alpha (-308 G/A) polymorphism may be used as a predictor of elevated tumour necrosis factor-alpha levels in patients with sepsis.
