Abstract
Diabetic kidney disease (DKD) is a prevalent and severe complications of diabetes and serves as the primary cause of end-stage kidney disease (ESKD) globally. Increasing evidence indicates that renal inflammation is critical in the pathogenesis of DKD. The nucleotide - binding oligomerization domain (NOD) - like receptor family pyrin domain containing 3 (NLRP3) inflammasome is the most extensively researched inflammasome complex and is considered a crucial regulator in the pathogenesis of DKD. The activation of NLRP3 inflammasome is regulated by various signaling pathways, including NF- κB, thioredoxin-interacting protein (TXNIP), and non-coding RNAs (ncRNA), among others. Natural products are chemicals extracted from living organisms in nature, and they typically possess pharmacological and biological activities. They are invaluable sources for drug design and development. Research has demonstrated that many natural products can alleviate DKD by targeting the NLRP3 inflammasome. In this review, we highlight the role of the NLRP3 inflammasome in DKD, and the pathways by which natural products fight against DKD via inhibiting the NLRP3 inflammasome activation, so as to provide novel insights for the treatment of DKD.

Abstract
Spaceflight and its associated stressors, such as microgravity, radiation exposure, confinement, circadian derailment and disruptive workloads represent an unprecedented type of exposome that is entirely novel from an evolutionary stand point. Within this perspective, we aimed to review the effects of prolonged spaceflight on immune-neuroendocrine systems, brain and brain-gut axis, cardiovascular system and musculoskeletal apparatus, highlighting in particular the similarities with an accelerated aging process. In particular, spaceflight-induced muscle atrophy/sarcopenia and bone loss, vascular and metabolic changes, hyper and hypo reaction of innate and adaptive immune system appear to be modifications shared with the aging process. Most of these modifications are mediated by molecular events that include oxidative and mitochondrial stress, autophagy, DNA damage repair and telomere length alteration, among others, which directly or indirectly converge on the activation of an inflammatory response. According to the inflammaging theory of aging, such an inflammatory response could be a driver of an acceleration of the normal, physiological rate of aging and it is likely that all the systemic modifications in turn lead to an increase of inflammaging in a sort of vicious cycle. The most updated countermeasures to fight these modifications will be also discussed in the light of their possible application not only for astronauts' benefit, but also for older adults on the ground.

Abstract
Sympathetic nerves play essential roles in the regulation of lung inflammation, and we investigated the effect of sympathetic denervation (SD) on sepsis-induced acute lung injury (ALI) in mice. Mice were randomized to the control, SD, ALI and SD + ALI, groups. SD and ALI were established through intratracheal 6-hydroxydopamine and intraperitoneal lipopolysaccharide, respectively. Models and gene expressions levels were evaluated by HE staining, ELISA, Western blotting and RT-qPCR. RNA extraction, whole transcriptome sequencing and subsequent biostatistical analysis were performed. Sympathetic denervation in the lungs significantly attenuated lung TNF-ɑ and norepinephrine expression, alleviated sepsis-induced acute lung injury and inhibited NF-κB signaling. Compared with the ALI group, the SD + ALI group exhibited 629 DE circRNAs, 269 DE lncRNAs,7 DE miRNAs and 186 DE mRNAs, respectively. Some DE RNAs were validated by RT-qPCR. CircRNA-miRNA-mRNA regulatory networks in the SD + ALI group revealed enrichment of the B-cell receptor signaling pathway, IL-17 signaling pathway, neuroactive ligand-receptor interaction, CAM, primary immunodeficiency, and cytokine-cytokine receptor interaction terms. The lncRNA-miRNA-mRNA network also revealed inflammation-related signaling pathways. Taken together, based on the successfully established models of SD and ALI, we show here that sympathetic nerves may regulate sepsis-induced ALI supposedly by affecting the expression of circRNAs, lncRNAs, miRNAs, and mRNAs in the lungs. These results may allow for further exploration of the roles of pulmonary sympathetic nerves in sepsis-induced ALI.

Abstract
Ulcerative colitis (UC) is a refractory inflammatory bowel disease that causes inflammation and ulcers in the digestive tract, and significantly reduces the patient's quality of life. While existing UC treatments have many challenges, nanotechnology, and small interfering RNA (siRNA) based formulations are novel and promising for UC treatment. We previously reported that intravenous administration of MPEG-PCL-CH2R4H2C nanomicelles had high inflammatory site accumulation and remarkable therapeutic effects on rheumatoid arthritis by a phenomenon similar to enhanced permeability and retention effect. In this study, we investigated the effects of siRNA delivered using MPEG-PCL-CH2R4H2C nanomicelles through intravenous administration to the inflammation site of dextran sulfate sodium-induced colitis mice. The MPEG-PCL-CH2R4H2C micelles had optimum physical properties and high siRNA compaction ability. Moreover, model-siRNA delivered through MPEG-PCL-CH2R4H2C showed higher accumulation in the inflammatory site than that of the naked siRNA. Furthermore, intravenous administration of MPEG-PCL-CH2R4H2C/siRelA micelles, targeting siRelA, a subunit of NF-κB, significantly decreased the shortening of large intestine, clinical score, and production of inflammatory cytokines compared the 5-ASA and naked siRelA. These results suggest that MPEG-PCL-CH2R4H2C is a useful carrier for the systemic delivery and accumulation of siRNA, thus improving its therapeutic effect.

Abstract
Triptolidenol (TPD) is an epoxy diterpene lactone from Tripterygium wilfordii, which has been used for chronic nephritis in China,and possessed various pharmacological properties, such as anti-inflammatory and anti-cancer activities. However, the precise molecular antitumor mechanism of TPD remains to be elucidated. In this study, we investigated the effects of TPD on human clear cell renal cell carcinoma (ccRCC) and investigated its precise anti-tumor mechanisms. It was showed that TPD significantly suppressed ccRCC cell proliferation, cell migration, and induced cell cycle arrest at S phase. Furthermore, TPD also induced apoptosis by activating the cytochrome c (cyt c)/caspase cascade signaling pathway. Moreover, using confocal immunofluorescence, a dual-luciferase reporter assay and molecular docking study, the results showed that TPD obviously reduced the expression of COX-2 by inhibiting the kinase activity of IKKβ via targeting its ATP-binding domain, and then attenuating the transactivation of NF-κB. Collectively, our study demonstrated that TPD suppressed renal cell carcinoma growth through disrupting NF-κB/COX-2 pathway by targeting ATP-binding sites of IKKβ, and provided pharmacological evidence that TPD exhibits potential use in the treatment of COX-2-mediated diseases such as ccRCC.

Abstract
In this study, we investigated whether the anti-inflammatory effects of tomatidine alleviate osteoarthritis (OA)-related pathology in primary articular chondrocytes and a rat OA model. STITCH database analysis identified 22 tomatidine-target genes that were enriched in 78 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Moreover,39 of the 105 OA-related KEGG pathways were related to tomatidine-target genes. The top two OA-related KEGG pathways with tomatidine-target genes were the MAPK and neutrophin signaling pathways. Pretreating primary chondrocytes with tomatidine suppressed interleukin-1β (IL-1β)-induced expression of iNOS, COX-2, MMP1, MMP3, MMP13, and ADAMTS-5. Tomatidine also suppressed IL-1β-induced degradation of collagen-II and aggrecan proteins by inhibiting NF-κB and MAPK signaling. In a rat OA model, histological and immunohistochemical analyses showed significantly less cartilage degeneration in thetibiofemoral joints of rats treated for 12 weeks with tomatidine after OA induction (experimental group) than in untreated OA group rats. However, micro-computed tomography (μ-CT) showed that tomatidine did not affect remodeling of the subchondral bone at the tibial plateau. These data shows that tomatidine suppresses IL-1β-induced inflammation in primary chondrocytes by inhibiting the NF-κB and MAPK signaling pathways, and protects against cartilage destruction in a rat OA model.

Abstract
MicroRNAs are important cellular mediators of mRNA degradation and translation repression, which in turn can have an impact on various processes and, if their function is perturbed, can cause disease. Here, we summarize the recent manuscript by Zhong et al. [(2017) Biosci. Rep. 37, BSR20160578], which explores microRNA-146a and how it may play an indirect yet vital role in the proliferation of osteoarthritis (OA) chondrocytes. The data presented by the authors could have important implications for future OA therapies.

Abstract
INTRODUCTION Recent studies demonstrated that cannabidiol had neuroprotective property. There is some evidence about effective role of cannabidiol in reduction of ischemic damages. It has been reported that infarct size is influenced by various factors after MCAO, including inflammatory factors. The aim of the present study was to evaluate the effect of cannabidiol on infarction volume and correlation of infarct size with tumor necrosis factor receptor 1 (TNFR1), and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) expression. METHODS Using stereotaxic surgery, guide cannula was implanted in the right lateral ventricle. Cannabidiol (50, 100, and 200 ng/rat) was injected through ntracerebroventricular (i.c.v.) route for 5 consecutive days . Then, the rats underwent 60 minutes of right middle cerebral artery occlusion (MCAO). After 24 h reperfusion, the infarct volume in total, cortex, piriform cortex-amygdala (Pir-Amy), and striatum areas of hemisphere were assessed. The expression of inflammatory factors such as TNFR1 and NF-κB in these regions were also studied. RESULTS The present results indicate that in the MCAO-induced cerebral ischemia, administration of cannabidiol (100 and 200 ng/rat) causes a significant reduction in infarction volume in comparison with the vehicle group. Also, there were significant correlations between decrease of regional infarct volume and TNFR1/NF-κB expression. CONCLUSION The results of this study indicate that cannabidiol reduced cerebral infarction possibly through diminishing TNFR1/NF-κB-induced neurotoxicity in transient focal cerebral ischemia.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Shenfu injection (SFI) is a commercial medicinal product approved by the China Food and Drug Administration that is widely used in the treatment of stroke and coronary heart disease. However, the material basis and the mechanism of SFI are not fully understood. AIM OF THE STUDY With network pharmacology analysis, our research committed to identify the anti-inflammatory ingredients and mechanism of SFI by combining high-throughput screening. MATERIALS AND METHODS We developed a bioactivity-based UPLC/Q-TOF-MS method followed by network pharmacology and identified the anti-inflammatory active ingredients of SFI from two different perspectives of network computing and high throughput screening. Then we verified the anti-inflammatory effect of SFI in vitro with endothelial cells. After detecting the cell viability, the expression of interleukin-6 (IL-6), inhibitor of nuclear factor kappa-B kinase (IKK), phosphorylated IKK, phosphorylated NF-κB and phosphorylated IκB-α from the supernatant were determined. RESULTS SFI could significantly suppress inflammatory responses, and the mechanism may be via an NF-κB-dependent pathway. The results of high throughput screening (HTS) revealed that protopanaxadiol glycosides (ginsenosides Rb1, Rb2, Rb3, Rc and Rd), protopanaxatriol glycosides (ginsenosides Rg1, Rg2, Re, Rf and F1), diester-type alkaloids (fuziline and neoline) and aconine derivatives (mesaconine and benzoyl-mesaconine) have anti-NF-κB activity. The three compounds (including benzoyl-mesaconine, fuziline and neoline) are the first reported SFI compounds to have NF-κB inhibitor activity. CONCLUSIONS SFI may play a critical role in counteracting inflammation through the NF-κB signaling pathway. The active ingredients are protopanaxadiol glycosides, protopanaxatriol glycosides, diester-type alkaloids and aconine derivatives.

Abstract
Activation of nuclear factor -kappa B (NF-κB) is associated with inflammation in the progression of diabetic nephropathy (DN). MiR-451 is closely linked to renal damage in DN. Large multifunctional protease 7 (LMP7), an immunoproteasome subunit, can activate NF-κB. However, it remained unclear whether miR-451 affected NF-κB-induced inflammation by regulating LMP7 in DN. In this study, deep sequencing, in situ hybridization, quantitative real-time PCR, dual-luciferase reporter gene assays, western blot and chromatin immunoprecipitation were respectively used. For the results, we found that miR-451 was markedly downregulated in the kidneys of db/db mice, PBMCs of DN patients and mesangial cells (MCs) cultured in high glucose conditions. Furthermore, miR-451 directly targeted LMP7 expression to inhibit NF-κB activity, and down-regulated transcription of proinflammatory molecules in MCs. More importantly, in the kidneys of db/db DN mice, increasing miR-451 level inhibited LMP7/NF-κB activity, and attenuated the urinary microalbumin excretion, blood glucose, and glomerular injury. In conclusion, these results provide new insights into the regulation of miR-451 via the LMP7/NF-κB central inflammatory pathway during progression of DN.

Abstract
Ethyl pyruvate (EP), a simple ester of pyruvic acid, has been shown to exert robust neuroprotection in various neuropathological conditions, such as, cerebral ischemia and KA-induced seizure animal models. The neuroprotective effect of EP is attributable to the anti-inflammatory, anti-oxidative, and anti-apoptotic effects. In the present study, we investigated convergence of anti-inflammatory and anti-oxidative functions of EP and present a novel molecular mechanism underlying anti-inflammatory effects of EP, which is conveyed by p300, a transcriptional co-activator for both Nuclear factor E2-related factor 2 (Nrf2) and p65. In BV2 cells, a microglia cell line, EP induced translocation of Nrf2 from the cytosol to the nucleus and enhanced the expression of hemeoxygenase 1 (HO-1) in a dose-dependent manner and 1h incubation with 10mM EP increased HO-1 to 4.9-fold. Nrf2 was found to translocate from the cytosol to the nucleus beginning 30 min after EP-treatment and binds to the antioxidant response element (ARE) located on HO-1 promoter. Interestingly, LPS-induced inducible NO synthase (iNOS) induction was substantially suppressed in EP-pre-treated BV2 cells and it was reverted by Nrf2 knockdown. We found that EP-induced Nrf2 accumulation in the nucleus recruits p300, a transcriptional co-activator of both Nrf2 and p65, inhibiting p65-p300 interaction. Competition between Nrf2 and p65 for p300 binding was confirmed by glutathione S-transferase (GST) pull down assay and reporter gene analysis. These results demonstrate that EP induced nuclear translocation of Nrf2 which binds to ARE along with p300 and hampers iNOS expression via depleting p300 from p65. This is a novel anti-inflammatory mechanism conveyed by EP, which enhances protective effect by converging anti-inflammatory and anti-oxidative effects and might be applicable to various Nrf2-activating agents, such as phytochemicals.
