Abstract
PURPOSE This study aimed to examine the impact of CA on DN and elucidate its underlying molecular mechanisms of inflammation. METHODS We fed C57BL/6 mice injected with streptozotocin to induce diabetes. In addition, we stimulated NRK-52E cells with 20 mmol/L d-glucose to mimic the diabetic condition. RESULTS Our findings demonstrated that CA effectively reduced blood glucose levels, and improved DN in mice models. Additionally, CA reduced kidney injury and inflammation in both mice models and in vitro models. CA decreased high glucose-induced ferroptosis of NRK-52E cells by inducing GSH/GPX4 axis. Conversely, the ferroptosis activator or the PI3K inhibitor reversed positive effects of CA on DN in both mice and in vitro models. CA suppressed PAQR3 expression in DN models to promote PI3K/AKT activity. The PAQR3 activator reduced the positive effects of CA on DN in vitro models. Moreover, CA directly targeted the PAQR3 protein to enhance the ubiquitination of the PAQR3 protein. CONCLUSION Overall, our study has uncovered that CA promotes the ubiquitination of PAQR3, leading to the attenuation of ferroptosis in DN. This effect is achieved through the activation of the PI3K/AKT signaling pathways by disrupting the interaction between PAQR3 and the P110α pathway. These findings highlight the potential of CA as a viable therapeutic option for the prevention of DN and other forms of diabetes.

The m6A methyltransferase METTL3 modifies Kcnk6 promoting on inflammation associated carcinogenesis is essential for colon homeostasis and defense system through histone lactylation dependent YTHDF2 binding. Int Rev Immunol 2024:1-16.

Abstract
Inflammation induces tumor formation and plays a crucial role in tumor progression and prognosis. KCNK6, by regulating K(+) efflux to reduce NLRP3 Inflammasome-induced lung injury, relaxes the aorta. This study aims to elucidate the effects and biological mechanism of KCNK6 in inflammation-associated carcinogenesis, which may be essential for colon homeostasis and the defense system. To induce colitis, mice were given 3.0% Dextran Sodium Sulfate (DSS) in their drinking water for 7 days. The Azoxymethane (AOM) +DSS method was used to induce colon cancer in the mice model. Bone marrow-derived macrophages (BMDM) from Kcnk6-/- mice, AW264.7 cells, and human colon cancer HCT116 and Caco2 cells were used as in vitro models. The loss of Kcnk6 prevented spontaneous colitis and restored mucosal integrity and homeostatic molecules. Additionally, the loss of Kcnk6 reduced the severity of AOM/DSS-induced carcinogenesis. Kcnk6 promoted cell viability and proliferation in HCT-116 or Caco-2 cells. The loss of Kcnk6 inhibited the levels of inflammatory factors in BMDM cells. Kcnk6 accelerated potassium channel activity, inducing NLRP3 inflammasome activation. METTL3-mediated m6A modification increased Kcnk6 stability in a YTHDF2-dependent manner. Histone lactylation activated the transcription of YTHDF2/Kcnk6. Our study revealed the important role of Kcnk6 in inflammation-associated carcinogenesis progression. The m6A methyltransferase METTL3 and histone lactylation increased Kcnk6 stability in a YTHDF2-dependent manner, providing a potential strategy for inflammation-associated carcinogenesis or colorectal cancer therapy.

Abstract
Acute myocardial infarction (AMI) is the high incidence rate and mortality of common cardiovascular disease. Herein, we explored the critical role of TRIM11 in AMI and its underlying mechanism. Serum from patients with AMI were collected from our hospital. Mice of model group received angiotensin II. Mice of model + TRIM11 group received with Ang II and TRIM11 vectors. Mice of sham group received normal saline. H9c2 cells were performed transfections using Lipofectamine 2000 (Thermo Fisher Scientific Inc, Shanghai, China), and treated with Ang II. TRIM11 mRNA expression was reduced, was negative correlation with collagen I/III mRNA expression, systolic blood pressure, diastolic blood pressure, left anteroposterior atrial diameter, right atrial diameter, or left ventricular ejection fraction in patient with AMI. TRIM11 mRNA and protein expression were also suppressed. METTL3 regulates TRIM11 methylation to reduce TRIM11 gene stability in model of AMI. TRIM11 gene ameliorated AMI in mice model. TRIM11 gene reduced reactive oxygen species production level of cardiomyocyte in-vitro model. TRIM11 gene reduced ferroptosis of cardiomyocyte in-vitro model. TRIM11 gene reduced ferroptosis by the inhibition of mitochondrial damage of cardiomyocyte in model of AMI. TRIM11 induced Dusp6 protein expression. Bioluminescence imaging showed that TRIM11 virus increased Dusp6 expression in heart tissue of mice model. The inhibition of Dusp6 reduced the effects of TRIM11 on ferroptosis of cardiomyocyte in model of AMI. In conclusion, this study demonstrates that TRIM11 improves AMI by regulating Dusp6 to inhibit ferroptosis of cardiomyocyte, and suggest a novel target for AMI.

Abstract
Colorectal cancer (CRC) continues to be a significant contributor to global morbidity and mortality. Emerging evidence indicates that disturbances in gut microbial composition, the formation of reactive oxygen species (ROS), and the resulting inflammation can lead to DNA damage, driving the pathogenesis and progression of CRC. Notably, bacterial metabolites can either protect against or contribute to oxidative stress by modulating the activity of antioxidant enzymes and influencing signaling pathways that govern ROS-induced inflammation. Additionally, microbiota byproducts, when supplemented through probiotics, can affect tumor microenvironments to enhance treatment efficacy and selectively mediate the ROS-induced destruction of CRC cells. This review aims to discuss the mechanisms by which taxonomical shifts in gut microbiota and related metabolites such as short-chain fatty acids, secondary bile acids, and trimethylamine-N-oxide influence ROS concentrations to safeguard or promote the onset of inflammation-mediated CRC. Additionally, we focus on the role of probiotic species in modulating ROS-mediated signaling pathways that influence both oxidative status and inflammation, such as Nrf2-Keap1, NF-κB, and NLRP3 to mitigate carcinogenesis. Overall, a deeper understanding of the role of gut microbiota on oxidative stress may aid in delaying or preventing the onset of CRC and offer new avenues for adjunct, CRC-specific therapeutic interventions such as cancer immunotherapy.

Abstract
GPR41, a G protein-coupled receptor, serves as a sensor for short-chain fatty acids and plays a crucial role in regulating multiple physiological processes such as the maintenance of metabolic and immune homeostasis. Therefore, the modulation of GPR41 has garnered attention as a potential strategy for the treatment of various disorders. We conducted a structure-activity relationship study on a lead tetrahydroquinolone derivative bearing a 2-(trifluoromethoxy)benzene group that displayed antagonistic activity toward GPR41. Modification of the aryl group attached to the furan moiety revealed that derivatives containing di- or trifluorobenzene, instead of 2-(trifluoromethoxy)benzene, exhibited agonistic activity toward GPR41, comparable with the reported agonistic modulator AR420626. These results suggest that the aryl group plays a pivotal role in regulating the activity of compounds toward GPR41, providing valuable insights for the design of GPR41 modulators.

Abstract
G-protein-coupled receptors are a diverse class of cell surface receptors that orchestrate numerous physiological functions. The G-protein-coupled receptors, GPR41 and GPR43, sense short-chain fatty acids (SCFAs), which are metabolites of dietary fermentation by the host's intestinal bacteria. These receptors have gained attention as potential therapeutic targets against various diseases because of their SCFA-mediated beneficial effects on the host's intestinal health. Mounting evidence has associated the activity of these receptors with chronic metabolic diseases, including obesity, diabetes, inflammation, and cardiovascular disease. However, despite intensive research using various strategies, including gene knockout (KO) mouse models, evidence about the precise roles of GPR41 and GPR43 in disease treatment remains inconsistent. Here, we comprehensively review the latest findings from functional studies of the signaling mechanisms that underlie the activities of GPR41 and GPR43, as well as highlight their multifaceted roles in health and disease. We anticipate that this knowledge will guide future research priorities and the development of effective therapeutic interventions.

Abstract
BACKGROUND The repair of bone defects caused by periodontal diseases is a difficult challenge in clinical treatment. Dental pulp stem cells (DPSCs) are widely studied for alveolar bone repair. The current investigation aimed to examine the specific mechanisms underlying the role of Zinc finger DHHC-type palmitoyl transferases 16 (ZDHHC16) in the process of osteogenic differentiation (OD) of DPSCs. METHODS The lentiviral vectors ZDHHC16 or si-ZDHHC16 were introduced in the DPSCs and then the cells were induced by an odontogenic medium for 21 days. Subsequently, Quantitate Polymerase Chain Reaction (PCR), immunofluorescent staining, proliferation assay, ethynyl deoxyuridine (EdU) staining, and western blot analysis were used to investigate the specific details of ZDHHC16 contribution in OD of DPSCs. RESULTS Our findings indicate that ZDHHC16 exhibited a suppressive effect on cellular proliferation and oxidative phosphorylation, while concurrently inducing ferroptosis in DPSCs. Moreover, the inhibition of ZDHHC16 promoted cell development and OD and reduced ferroptosis of DPSCs. The expression of p-CREB was suppressed by ZDHHC16, and immunoprecipitation (IP) analysis revealed that ZDHHC16 protein exhibited interconnection with cAMP-response element binding protein (CREB) of DPSCs. The CREB suppression reduced the impacts of ZDHHC16 on OD and ferroptosis of DPSCs. The activation of CREB also reduced the influences of si-ZDHHC16 on OD and ferroptosis of DPSCs. CONCLUSIONS These findings provide evidences to support a negative association between ZDHHC16 and OD of DPSCs, which might be mediated by ferroptosis of DPSCs via CREB.

Abstract
Reputable evidence from multiple studies suggests that excessive and uncontrolled inflammation plays an indispensable role in mediating, amplifying, and protracting acute lung injury (ALI). Traditionally, immunity and energy metabolism are regarded as separate functions regulated by distinct mechanisms, but recently, more and more evidence show that immunity and energy metabolism exhibit a strong interaction which has given rise to an emerging field of immunometabolism. Mammalian lungs are organs with active fatty acid metabolism, however, during ALI, inflammation and oxidative stress lead to a series metabolic reprogramming such as impaired fatty acid oxidation, increased expression of proteins involved in fatty acid uptake and transport, enhanced synthesis of fatty acids, and accumulation of lipid droplets. In addition, obesity represents a significant risk factor for ALI/ARDS. Thus, we have further elucidated the mechanisms of obesity exacerbating ALI from the perspective of fatty acid metabolism. To sum up, this paper presents a systematical review of the relationship between extensive fatty acid metabolic pathways and acute lung injury and summarizes recent advances in understanding the involvement of fatty acid metabolism-related pathways in ALI. We hold an optimistic believe that targeting fatty acid metabolism pathway is a promising lung protection strategy, but the specific regulatory mechanisms are way too complex, necessitating further extensive and in-depth investigations in future studies.

Abstract
BACKGROUND Acute cerebral infarction (ACI) is a common neurological disease that is associated with high morbidity, disability and mortality rates. At present, antiplatelet therapy is a necessary treatment for ACI. The present study aimed to investigate the effects of omentin-1 on the intravenous thrombolysis of ACI. OBJECTIVE The present study aimed to investigate the effects of omentin-1 on the intravenous thrombolysis of ACI. MATERIAL AND METHODS The mouse model of ACI was induced using male C57BL/6 mice through middle cerebral artery occlusion (MCAO). Meanwhile, the murine BV2 microglial cells were pretreated with 0.1 mg/ml of lipopolysaccharide (LPS), and then induced with 2 mM of adenosine triphosphate (ATP). RESULTS The omentin-1 mRNA expression in patients receiving intravenous thrombolysis for ACI was down-regulated compared with the normal group. Additionally, the serum level of omentin-1 was negatively correlated with National Institute of Health Stroke Scale (NIHSS) score or serum level of IL-1β or MMP-2 in patients receiving intravenous thrombolysis for ACI. Meanwhile, the serum mRNA expression of omentin-1 was positively correlated with Barthel index or high-sensitivity C-reactive protein (hs-CRP) in patients undergoing intravenous thrombolysis for ACI. As observed from the in vitro model, Omentin-1 reduced inflammation, promoted cell growth, alleviated ROS-induced oxidative stress, and enhanced AMPK activity through activating NLRP3 ubiquitination. Omentin-1 presented ACI in the mouse model of ACI. Regulating AMPK activity contributed to controlling the effects of Omentin-1 on the in vitro model. CONCLUSIONS Omentin-1 reduced neuroinflammation and ROS-induced oxidative stress in the mouse model of ACI, which was achieved by inhibiting NLRP3 ubiquitination through regulating AMPK activity. Therefore, omentin-1 may serve as a treatment factor for the intravenous thrombolysis of ACI in further clinical application.

Abstract
Respiratory failure caused by severe acute lung injury (ALI) is the main cause of mortality in patients with COVID-19.This study aimed to investigate the effects and underlying biological mechanism of Apolipoprotein C3 (ApoC3) in ALI. To establish an in vivo model, C57BL/6 mice were exposed by lipopolysaccharide (LPS). For the in vitro model, murine bone marrow-derived macrophages (BMDMs) or RAW264.7 cells were stimulated with LPS + adenosine triphosphate (ATP). Serum levels of ApoC3 were found to be upregulated in patients with COVID-19 or pneumonia-induced ALI. Inhibition of ApoC3 reduced lung injury in an ALI model, while overexpression of ApoC3 promoted lung injury. ApoC3 induced mitochondrial damage-mediated pyroptosis in ALI through the activation of the NOD-like receptorprotein 3 (NLRP3) inflammasome. ApoC3 recombinant protein significantly increased SCIMP expression in the lung tissue of mice models with ALI. ApoC3 also facilitated the interaction between the SLP adapter and CSK-interacting membrane protein (SCIMP) protein and Spleen tyrosine kinase (SYK) protein in the ALI model. Moreover, ApoC3 accelerated calcium-dependent reactive oxygen species (ROS) production in the ALI model. The effects of ApoC3 on pyroptosis were mitigated by the use of a pyroptosis inhibitor or an ROS inhibitor in the ALI model. Furthermore, ApoC3 activated the expression of SYK, which in turn induced NLRP3 inflammasome-regulated pyroptosis in the ALI model. METTL3 was found to mediate the m6A mRNA expression of ApoC3. Overall, our study highlights the crucial role of ApoC3 in promoting macrophage pyroptosis in ALI through calcium-dependent ROS production and NLRP3 inflammasome activation via the SCIMP-SYK pathway, providing a potential therapeutic strategy for ALI and other inflammatory diseases.

Abstract
The present study explored that the effects and its possible mechanisms of ring finger protein 20 (RNF20) in Postoperative survival rate of liver cancer in clinical. All the serum samples were collected from our hospital. Quantitative polymerase chain reaction (PCR) and microarray analysis, and RNA pull down assay were used in this study. We found that the serum RNF20 mRNA expression level in patients with liver cancer were down-regulated. Postoperative survival rate of RNF20 high expression was higher than that of RNF20 low expression. Then, over-expression of RNF20 diminished liver cancer cell proliferation and metastasis. RNF20 reduced Warburg effect of liver cancer. RNF20 expression regulated NOD-like receptor protein 3 (NLRP3) expression and increased NLRP3 Ubiquitination. NLRP3 participated in the effects of RNF20 on cell proliferation, and not affected on Warburg effect of liver cancer. Our study demonstrated that the serum RNF20 expression level was down-regulated in liver cancer, and promoted postoperative survival rate. RNF20 can reduce cancer progression of liver cancer by NLRP3 signal pathway, suggesting that it may prove to be a potential therapeutic target for postoperative survival rate of liver cancer.

Abstract
BACKGROUND The present study investigated the roles and mechanisms of platelet-derived exosomes in sepsis-induced acute renal injury. METHODS The blood samples of septic patients and healthy controls were collected for clinical examination. The plasma levels of miR-223-3p and NLRP3 mRNA were analyzed by qRT-PCR and the serum IL-1β and creatinine levels were quantified by enzyme-linked immunosorbent assay (ELISA). C57BL/6 mice injected with LPS (lipopolysaccharide) were employed as the animal model for sepsis-induced acute renal injury. Human coronary artery endothelial cells (HCAECs) were treated with TNF-α as a cellular model for sepsis-induced endothelial damages. RESULTS The number of PMP (platelet-derived microparticles) in patients with sepsis was increased. The level of miR-223-3p in the platelet exosomes isolated from the serum sample in patients with sepsis was significantly lower than that of the healthy controls. The level of miR-223-3p was also decreased in the platelet exosomes of mouse model with sepsis-induced acute renal injury. Downregulating miR-223-3p promoted sepsis-induced acute renal injury in mice model, while the administration of miR-223-3p reduced the inflammation in endothelial cells of sepsis-induced acute renal injury. NLRP3 (NLR Family Pyrin Domain Containing 3) was identified as one target of miR-223-3p in the platelet exosomes of sepsis-induced acute kidney injury. miR-223-3p attenuated NLRP3-induced pyroptosis in endothelial cell model of sepsis-induced acute kidney injury. CONCLUSION Our data suggest that platelet exosome-derived miR-223-3p negatively regulates NLRP3-dependent inflammasome to suppress pyroptosis in endothelial cells. Decreased miR-223-3p expression promotes the inflammation in sepsis-induced acute renal injury. Targeting miR-223-3p may be developed into a therapeutic approach for sepsis-induced acute renal injury.

Abstract
Although great progress has been made in the diagnosis and treatment of acute myocardial infarction (AMI) in recent years, its morbidity and mortality are still relatively high. In this study, we explain that the function of Sestrin2 gene in Anxiety and Depression Myocardial infarction and its possible mechanism. 26 patients with Anxiety and Depression Myocardial infarction (ADMI) and 26 normal volunteers were collected from our hospital. All mice anaesthetized using 50 mg/kg of pentobarbital sodium and the left anterior descending arteries (LAD) were ligated to induce myocardial infarction. H9c2 cells were stimulated with 5% oxygen (O2) and 5% carbon dioxide (CO2) and 90% N2 for 24 h. The serum expression of Sestrin2 in patients with ADMI was up-regulated. Sestrin2 gene up-regulation reduced collagen I/II and KEAP1 mRNA expressions, and increased GPX4 and Nrf2 mRNA expressions in vitro model of AMI. Down-regulation of Sestrin2 increased collagen I/II and KEAP1 mRNA expressions, and decreased GPX4 and Nrf2 mRNA expressions in vitro model of AMI. These data confirmed that Sestrin2 reduced inflammation and ferroptosis in model of ADMI by LKB1-mediated AMPK activation. This infers that Sestrin2 is potential target to be used in the treatment of premature AMI.

Abstract
OBJECTIVE This experiment explored the function of TTC4 in rheumatoid arthritis inflammation and its possible mechanism. METHODS C57BL/6 mice were immunized intradermally with bovine type II collagen. Lipopolysaccharide induction was performed on RAW264.7 cells. RESULTS The mRNA expression of TTC4 in articular tissue of mice with rheumatoid arthritis was downregulated. Sh-TTC4 virus increased arthritis score, morphological change score, paw edema, and spleen index, as well as alkaline phosphatase level in mice with rheumatoid arthritis. Sh-TTC4 virus increased the levels of inflammatory factors and MDA, and decreased anti-oxidant factors in articular tissue of mice with rheumatoid arthritis. TTC4 reduced inflammation and oxidative stress in an in vitro model. TTC4 regulated HSP70 in a rheumatoid arthritis model. The inhibition of HSP70 reduced the effects of sh-TTC4 gene in mice with rheumatoid arthritis. METTL3 reduced the stability of the TTC4 gene. CONCLUSION In this study, the TTC4 gene reduced oxidative response and inflammation in the rheumatoid arthritis model through the HSP70/NLRP3 pathway. Therefore, it can be concluded that TTC4 can be used as diagnosis and prognosis evaluation of rheumatoid arthritis.

Abstract
A wide spectrum of metabolites (mainly, the three major nutrients and their derivatives) can be sensed by specific sensors, then trigger a series of signal transduction pathways and affect the expression levels of genes in epigenetics, which is called metabolite sensing. Life body regulates metabolism, immunity, and inflammation by metabolite sensing, coordinating the pathophysiology of the host to achieve balance with the external environment. Metabolic reprogramming in cancers cause different phenotypic characteristics of cancer cell from normal cell, including cell proliferation, migration, invasion, angiogenesis, etc. Metabolic disorders in cancer cells further create a microenvironment including many kinds of oncometabolites that are conducive to the growth of cancer, thus forming a vicious circle. At the same time, exogenous metabolites can also affect the biological behavior of tumors. Here, we discuss the metabolite sensing mechanisms of the three major nutrients and their derivatives, as well as their abnormalities in the development of various cancers, and discuss the potential therapeutic targets based on metabolite-sensing signaling pathways to prevent the progression of cancer.

Abstract
BACKGROUND Cardiac dysfunction is an important component of multiple organ failure caused by sepsis, and an important cause of high mortality in patients with sepsis. Herein, we attempted to determine whether myo-inositol oxygenase (MIOX) has proinflammation enzyme in infection-induced cardiac dysfunction (IICD) and its underlying mechanism. METHODS Patients with IICD were collected by our hospital. A mouse model of IICD was induced into male db/db mice by cecal ligation and puncture (CLP). All mice were injected with 20 μL of LV-MIOX or LV-control short hairpin RNA using a 0.5-mL insulin syringe. On the second day, all mice were induced by CLP. H9C2 cell was also induced with lipopolysaccharide and adenosine triphosphate. Quantitative analysis of messenger RNAs (mRNAs) and gene microarray hybridization was used to analyze the mRNA expression levels. Enzyme-linked immunosorbent assay, immunofluorescence, and Western blot analysis were used to analyze the protein expression levels. RESULTS The serum expressions of MIOX mRNA level in patients with IICD were upregulated compared to normal healthy volunteers. MIOX promoted inflammation levels in the in vitro model of IICD. Si-MIOX inhibited inflammation levels in the in vitro model of IICD. MIOX accelerated inflammation and cardiac dysfunction in infection-induced mice. MIOX interacted with NLR family pyrin domain containing 3 (NLRP3) protein to reduce the degradation of NLRP3. The inhibition of MIOX reversed the effects of NLRP3 in the in vitro model of cardiac dysfunction. CONCLUSIONS Taken together, these findings demonstrate that MIOX accelerates inflammation in the model of IICD, which may be, at least in part, attributable to NLRP3 activity by the suppression of NLRP3 degradation in IICD.

Abstract
BACKGROUND As an organelle essential for intracellular energy supply, mitochondria are involved in intracellular metabolism and inflammation, and cell death. The interaction of mitochondria with the NLRP3 inflammasome in the development of lung diseases has been extensively studied. However, the exact mechanism by which mitochondria mediate the activation of the NLRP3 inflammasome and trigger lung disease is still unclear. METHODS The literatures related to mitochondrial stress, NLRP3 inflammasome and lung diseases were searched in PubMed. RESULTS This review aims to provide new insights into the recently discovered mitochondrial regulation of the NLRP3 inflammasome in lung diseases. It also describes the crucial roles of mitochondrial autophagy, long noncoding RNA, micro RNA, altered mitochondrial membrane potential, cell membrane receptors, and ion channels in mitochondrial stress and regulation of the NLRP3 inflammasome, in addition to the reduction of mitochondrial stress by nuclear factor erythroid 2-related factor 2 (Nrf2). The effective components of potential drugs for the treatment of lung diseases under this mechanism are also summarized. CONCLUSION This review provides a resource for the discovery of new therapeutic mechanisms and suggests ideas for the development of new therapeutic drugs, thus promoting the rapid treatment of lung diseases.

Abstract
Aim: Sepsis is an extremely complex, threatening and difficult-to-treat disease, which can occur at any age and under any underlying disease. RNF20 regulate NF-kappaB (NF-κB) signaling pathway and the transcription of inflammatory factors of target genes. Therefore, it is of great significance to study the function of RNF20 in the clinical treatment of sepsis and its underlying mechanisms.Methods: C57BL/6 mice were subjected to cecal ligation and puncture (CLP) surgery. THP-1 cells were induced with Lipopolysaccharide for 4 h.Results: RNF20 gene, mRNA expression and protein expression were reduced in patients with sepsis and mice with sepsis. Based on RNF20 deletion (RNF20-/-) mice, these were found to be increased inflammation reactions in RNF20-/- mice. However, the RNF20 human protein reduced inflammation reactions in mice with sepsis. In vitro model of sepsis, over-expression of RNF20 inhibited inflammation reactions by inducing Vitamin D Receptor (VDR), while down-regulation of RNF20 promoted inflammation reactions through the suppression of VDR. RNF20 protein was interlinked with VDR protein, and VDR protein was also interlinked with NLRP3. Furthermore, VDR promoted NLRP3 ubiquitination and reduced NLRP3 function in vitro model of sepsis.Conclusion: These studies demonstrate that RNF20 suppressed inflammation reactions in models with sepsis through NLRP3 inflammasome and NLRP3 ubiquitination by activating VDR.

Abstract
In recent years, the incidence rate of nonalcoholic fatty liver disease (NAFLD) has been increasing year by year. The experiments conducted on rat elucidated the effect and underlying mechanism of dapagliflozin in NAFLD. Sprague Dawley rats were fed with HFD (Fat accounts for 52%, carbohydrate 34% and protein 14%) for 12 weeks as NAFLD model. Dapagliflozin presented NAFLD in rat model. Dapagliflozin reduced oxidative stress and inflammation in rat model of NAFLD. Dapagliflozin reduced oxidative stress and inflammation in vitro model of NAFLD. Dapagliflozin in a model of NAFLD metabolized into histamine H1 receptor, caffeine metabolism, mannose type O-glycan biosynthesis, choline metabolism in cancer, tryptophan metabolism, and glycerophospholipid metabolism. Dapagliflozin induced AMPK/NLRP3 signaling pathway. The regulation of AMPK/NLRP3 signaling pathway affected the effects of dapagliflozin on nonalcoholic fatty liver. In summary, dapagliflozin plays a preventative role in NAFLD through metabolite extraction, the inhibition of oxidative stress, and inflammation by AMPK/NLRP3 signaling pathway. Dapagliflozin may be a potential therapeutic agent for oxidative stress and inflammation in model of NAFLD.

Abstract
Purpose The most prevalent primary malignant tumor of CNS is glioma, which has a dismal prognosis. The theory of oxidative stress is one of the important theories in the study of its occurrence and development mechanism. In this study, the impacts of PCBP2 on glioma sufferers and the possible mechanisms were examined. Methods Patients with glioma were obtained from May 2017 to July 2018. Quantitative PCR, microarray analysis, western blot analysis, and immunofluorescence were used in this experiment. Results PCBP2 mRNA expression level and protein expression in patients with glioma were upregulated compared with paracancerous tissue. OS and DFS of PCBP2 low expression in patients with glioma were higher than those of PCBP2 high expression. PCBP2 promoted the progression and metastasis of glioma. PCBP2 reduced oxidative stress-induced apoptosis of glioma. PCBP2 suppressed the cGAS/STING pathway of glioma. PCBP2 protein interlinked with cGAS and cGAS was one target for PCBP2. METTL3-mediated m6A modification increases PCBP2 stability. Conclusion Along the cGAS-STING signal pathway, PCBP2 decreased the apoptosis that oxidative stress-induced glioma caused, which might be a potential target to suppress oxidative stress-induced apoptosis of glioma.

Abstract
Schisandra chinensis, as a Chinese functional food, is rich in unsaturated fatty acids, minerals, vitamins, and proteins. Hence, this study was intended to elucidate the effects and biological mechanism of Schisandrin A from Schisandra chinensis in DN. C57BL/6 mice were fed with a high-fat diet and then injected with streptozotocin (STZ). Human renal glomerular endothelial cells were stimulated with 20 mmol/L d-glucose for DN model. Schisandrin A presented acute kidney injury in mice of DN. Schisandrin A reduced oxidative stress and inflammation in model of DN. Schisandrin A reduced high glucose-induced ferroptosis and reactive oxygen species (ROS-)-mediated pyroptosis by mitochondrial damage in model of DN. Schisandrin A directly targeted AdipoR1 protein and reduced LPS+ATP-induced AdipoR1 ubiquitination in vitro model. Schisandrin A activated AdipoR1/AMPK signaling pathway and suppressed TXNIP/NLRP3 signaling pathway in vivo and in vitro model of DN. Conclusively, our study revealed that Schisandrin A from Schisandra chinensis attenuates ferroptosis and NLRP3 inflammasome-mediated pyroptosis in DN by AdipoR1/AMPK-ROS/mitochondrial damage. Schisandrin A is a possible therapeutic option for DN or other diabetes.

Human Umbilical Cord Mesenchymal Stem Cells Improve Premature Ovarian Failure through Cell Apoptosis of miR-100-5p/NOX4/NLRP3. BIOMED RESEARCH INTERNATIONAL 2022; 2022:3862122. [PMID: 35845923 PMCID: PMC9283025 DOI: 10.1155/2022/3862122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 06/02/2022] [Accepted: 06/07/2022] [Indexed: 11/17/2022]
Abstract
Premature ovarian failure refers to a series of symptoms of perimenopausal hot flashes, night sweats, decreased libido, vaginal dryness, insomnia, reduced menstruation, sparse hair, even amenorrhea, and even infertility before the age of 40 due to the decline of ovarian function. Premature ovarian failure is a common and difficult disease in gynecology. Its prevalence is increasing gradually, and the trend is younger. The aim of this experiment was to elucidate the role of human umbilical cord mesenchymal stem cells (HUCMSCs) in premature ovarian failure and its mechanism. HUCMSCs, KGN cells, and HEK293T cells were used in this experiment. Quantitative PCR and microarray analysis, ELISA inflammation and oxidative stress kits, RNA pull-down assay, luciferase reporter assay, proliferation assay, EDU staining, and Western blot analysis were used. In an in vitro model of premature ovarian failure, HUCMSCs attenuated inflammatory response, oxidative stress, and apoptosis. HUCMSCs ameliorated the premature ovarian failure model. The miR-100-5p expression was induced by HUCMSCs through methylation. miR-100-5p regulation influenced the role of HUCMSCs in an in vitro model of premature ovarian failure. HUCMSCs inhibited the in vitro expression of NOX4, NLRP3, and GSDMD proteins in the model. NOX4/NLRP3 signaling pathway affects the role of HUCMSCs in an in vitro model of premature ovarian failure through miR-100-5p. This experiment elucidated the role of HUCMSCs in premature ovarian failure and its mechanism, with a view to providing a clinical reference.

Abstract
Oat containing rich β-glucan, polyphenols, flavonoids, saponins, alkaloids, and other substances shows good biological activities. Therefore, the present study aimed to uncover the possible mechanism and therapeutic effect of Avenanthramide C in lessening inflammatory responses in pediatric pneumonia. Pediatric pneumonia was induced by liposaccharide (LPS) for vivo model and vitro model. Macrophage was performed to determine the mechanism and effects of Avenanthramide C in pediatric pneumonia. NLRP3 activity participated in the effects of Avenanthramide C in pediatric pneumonia. Avenanthramide C induced p-PI3K and p-Akt expressions and reduced ubiquitination of PI3K expression in pediatric pneumonia. On the other hand, Avenanthramide C integrated serine at 821 sites of the PI3K protein function. Avenanthramide C reduced ROS (reactive oxygen species)-induced mitochondrial damage by PI3K/AKT function in a model of pediatric pneumonia. Avenanthramide C protects pyroptosis in a model of pediatric pneumonia by PI3K/AKT/Nrf2/ROS signaling. Taken together, our results demonstrated that Avenanthramide C protects pyroptosis through dependent ROS-induced mitochondrial damage by PI3K ubiquitination and phosphorylation in a model of pediatric pneumonia, suggesting its potential use for the treatment of pediatric pneumonia and other inflammatory diseases.
