Efficacy of ginseng-based Renshenguben oral solution for cancer-related fatigue among patients with advanced-stage hepatocellular carcinoma:A prospective multicenter cohort study

Background:Cancer-related fatigue(CRF)is a common and debilitating symptom experienced by patients with advanced-stage cancer,especially those undergoing antitumor therapy.This study aimed to evaluate the efficacy and safety of Renshenguben(RSGB)oral solution,a ginseng-based traditional Chinese medicine,in alleviating CRF in patients with advanced hepatocellular carcinoma(HCC)receiving antitumor treatment.Methods:In this prospective,open-label,controlled,multicenter study,patients with advanced HCC at BCLC stage C and a brief fatigue inventory(BFI)score of≥4 were enrolled.Participants were assigned to the RSGB group(RSGB,10 mL twice daily)or the control group(with supportive care).Primary and secondary endpoints were the change in multidimensional fatigue inventory(MFI)score,and BFI and functional assessment of cancer therapy-hepatobiliary(FACT-Hep)scores at weeks 4 and 8 after enrollment.Adverse events(AEs)and toxicities were assessed.Results:A total of 409 participants were enrolled,with 206 assigned to the RSGB group.At week 4,there was a trend towards improvement,but the differences were not statistically significant.At week 8,the RSGB group exhibited a significantly lower MFI score(P<0.05)compared to the control group,indicating improved fatigue levels.Additionally,the RSGB group showed significantly greater decrease in BFI and FACT-Hep scores at week 8(P<0.05).Subgroup analyses among patients receiving various antitumor treatments showed similar results.Multivariate linear regression analyses revealed that the RSGB group experienced a significantly substantial decrease in MFI,BFI,and FACT-Hep scores at week 8.No serious drug-related AEs or toxicities were observed.Conclusions:RSGB oral solution effectively reduced CRF in patients with advanced HCC undergoing antitumor therapy over an eight-week period,with no discernible toxicities.These findings support the potential of RSGB oral solution as an adjunctive treatment for managing CRF in this patient population.

The Combined Effect of Lumenato and Ceramide in the Protection of Collagen Damage Induced by Neutrophils in Normal Human Dermal Fibroblasts

Introduction: Collagen is the primary structural protein fibroblasts produce in the skin’s extracellular matrix. Infiltration of neutrophils into the epidermis and dermis by exposure to UV causes collagen damage and contributes to photoaging. Methods: To study the combined effect of Lumenato and ceramide in preventing collagen-1 damage induced by phagocytes, we used co-cultures of normal human dermal fibroblasts (fibroblasts) and activated human neutrophils. The present study aimed to determine the protective effect of the combination of Lumenato and ceramide on fibroblast collagen-1 damage induced by neutrophils. Results: Lumenato (in the range of 6.5 - 208 μg/ml) or ceramide (in the range of 0.1 - 50 μM) inhibited the production of superoxides and MPO by TNFα-stimulated neutrophils, as well as the production of NO by LPS-stimulated macrophages in a dose-dependent manner. The combinations of Lumenato and ceramide, in low concentrations, caused synergistic prevention of fibroblasts’ collagen-1 damage induced by TNFα-activated neutrophils, detected by fluorescence immunostaining and WB analysis. MPO activity in the supernatants of the co-cultures was also synergistically inhibited. Adding Lumenato or ceramide singly or in combinations in these low concentrations to the fibroblast cultures did not affect the expression of collagen-1. The combinations of Lumenato or ceramide in these concentrations also caused a synergistic inhibition of NO production by activated macrophages. Conclusions: The results suggest that combining low concentrations of Lumenato and ceramide results in synergistic protection against fibroblasts’ collagen-1 damage induced by neutrophils, thus indicating their possible potential for enhanced skin health.

CRABP2 regulates infiltration of cancer-associated fibroblasts and immune response in melanoma

Finding biomarkers for immunotherapy is an urgent issue in cancer treatment.Cellular retinoic acid-binding protein 2(CRABP2)is a controversial factor in the occurrence and development of human tumors.However,there is limited research on the relationship between CRABP2 and immunotherapy response.This study found that negative correlations of CRABP2 and immune checkpoint markers(PD-1,PD-L1,and CTLA-4)were observed in breast invasive carcinoma(BRCA),skin cutaneous melanoma(SKCM),stomach adenocarcinoma(STAD)and testicular germ cell tumors(TGCT).In particular,in SKCM patients who were treated with PD-1 inhibitors,high levels of CRABP2 predicted poor prognosis.Additionally,CRABP2 expression was elevated in cancer-associated fibroblasts(CAFs)at the single-cell level.The expression of CRABP2 was positively correlated with markers of CAFs,such as MFAP5,PDPN,ITGA11,PDGFRα/βand THY1 in SKCM.To validate the tumor-promoting effect of CRABP2 in vivo,SKCM xenograft mice models with CRABP2 overexpression have been constructed.These models showed an increase in tumor weight and volume.Enrichment analysis indicated that CRABP2 may be involved in immunerelated pathways of SKCM,such as extracellular matrix(ECM)receptor interaction and epithelial-mesenchymal transition(EMT).The study suggests that CRABP2 may regulate immunotherapy in SKCM patients by influencing infiltration of CAFs.In conclusion,this study provides new insights into the role of CRABP2 in immunotherapy response.The findings suggest that CRABP2 may be a promising biomarker for PD-1 inhibitors in SKCM patients.Further research is needed to confirm these findings and to explore the clinical implications of CRABP2 in immunotherapy.

Impact of STAT-signaling pathway on cancer-associated fibroblasts in colorectal cancer and its role in immunosuppression

Colorectal cancer(CRC)remains one of the most commonly diagnosed and deadliest types of cancer worldwide.CRC displays a desmoplastic reaction(DR)that has been inversely associated with poor prognosis;less DR is associated with a better prognosis.This reaction generates excessive connective tissue,in which cancer-associated fibroblasts(CAFs)are critical cells that form a part of the tumor microenvironment.CAFs are directly involved in tumorigenesis through different mechanisms.However,their role in immunosuppression in CRC is not well understood,and the precise role of signal transducers and activators of transcription(STATs)in mediating CAF activity in CRC remains unclear.Among the myriad chemical and biological factors that affect CAFs,different cytokines mediate their function by activating STAT signaling pathways.Thus,the harmful effects of CAFs in favoring tumor growth and invasion may be modulated using STAT inhibitors.Here,we analyze the impact of different STATs on CAF activity and their immunoregulatory role.

Calcitriol Suppressed Isoproterenol-induced Proliferation of Cardiac Fibroblasts via Integrinβ3/FAK/Akt Pathway

Objective Cardiac fibroblasts(CFs)proliferation and extracellular matrix deposition are important features of cardiac fibrosis.Various studies have indicated that vitamin D displays an anti-fibrotic property in chronic heart diseases.This study explored the role of vitamin D in the growth of CFs via an integrin signaling pathway.Methods MTT and 5-ethynyl-2′-deoxyuridine assays were performed to determine cell viability.Western blotting was performed to detect the expression of proliferating cell nuclear antigen(PCNA)and integrin signaling pathway.The fibronectin was observed by ELISA.Immunohistochemical staining was employed to evaluate the expression of integrinβ3.Results The PCNA expression in the CFs was enhanced after isoproterenol(ISO)stimulation accompanied by an elevated expression of integrin beta-3(β3).The blockade of the integrinβ3 with a specific integrinβ3 antibody reduced the PCNA expression induced by the ISO.Decreasing the integrinβ3 by siRNA reduced the ISO-triggered phosphorylation of FAK and Akt.Both the FAK inhibitor and Akt inhibitor suppressed the PCNA expression induced by the ISO in the CFs.Calcitriol(CAL),an active form of vitamin D,attenuated the ISO-induced CFs proliferation by downregulating the integrinβ3 expression,and phosphorylation of FAK and Akt.Moreover,CAL reduced the increased levels of fibronectin and hydroxyproline in the CFs culture medium triggered by the ISO.The administration of calcitriol decreased the integrinβ3 expression in the ISO-induced myocardial injury model.Conclusion These findings revealed a novel role for CAL in suppressing the CFs growth by the downregulation of the integrinβ3/FAK/Akt pathway.

17β-estradiol inhibits TGF-β-induced collagen gel contraction mediated by human Tenon fibroblasts via Smads and MAPK signaling pathways

AIM:To investigate the impact of 17β-estradiol on the collagen gels contraction(CGC)and inflammation induced by transforming growth factor(TGF)-βin human Tenon fibroblasts(HTFs).METHODS:HTFs were three-dimensionally cultivated in type I collagen-generated gels with or without TGF-β(5 ng/mL),17β-estradiol(12.5 to 100μmol/L),or progesterone(12.5 to 100μmol/L).Then,the collagen gel diameter was determined to assess the contraction,and the development of stress fibers was analyzed using immunofluorescence staining.Immunoblot and gelatin zymography assays were used to analyze matrix metalloproteinases(MMPs)and tissue inhibitors of metalloproteinases(TIMPs)being released into culture supernatants.Enzyme-linked immunosorbent assay(ELISA)and reverse transcription-quantitative polymerase chain reaction(RT-PCR)were used to detect interleukin(IL)-6,monocyte chemoattractant proteins(MCP)-1,and vascular endothelial growth factor(VEGF)in HTFs at the translational and transcriptional levels.The phosphorylation levels of Sma-and Mad-related proteins(Smads),mitogen-activated protein kinases(MAPKs),and protein kinase B(AKT)were measured by immunoblotting.Statistical analysis was performed using either the Tukey-Kramer test or Student’s unpaired t-test to compare the various treatments.RESULTS:The CGC caused by TGF-βin HTFs was significantly inhibited by 17β-estradiol(25 to 100μmol/L),and a statistically significant difference was observed when comparing the normal control group with 17β-estradiol concentrations exceeding 25μmol/L(P<0.05).The suppressive impact of 17β-estradiol became evident 24h after administration and peaked at 72h(P<0.05),whereas progesterone had no impact.Moreover,17β-estradiol attenuated the formation of stress fibers,and the production of MMP-3 and MMP-1 in HTFs stimulated by TGF-β.The expression of MCP-1,IL-6,and VEGF mRNA and protein in HTFs were suppressed by 100μmol/L 17β-estradiol(P<0.01).Additionally,the phosphorylation of Smad2 Smad3,p38,and extracellular signal-regulated kinase(ERK)were downregulated(P<0.01).CONCLUSION:17β-estradiol significantly inhibits the CGC and inflammation caused by TGF-βin HTFs.This inhibition is likely related to the suppression of stress fibers,inhibition of MMPs,and attenuation of Smads and MAPK(ERK and p38)signaling.17β-estradiol may have potential clinical benefits in preventing scar development and inflammation in the conjunctiva.

Activation of endogenous neurogenesis and angiogenesis by basic fibroblast growth factor-chitosan gel in an adult rat model of ischemic stroke

Attempts have been made to use cell transplantation and biomaterials to promote cell proliferation,differentiation,migration,and survival,as well as angiogenesis,in the context of brain injury.However,whether bioactive materials can repair the damage caused by ischemic stroke by activating endogenous neurogenesis and angiogenesis is still unknown.In this study,we applied chitosan gel loaded with basic fibroblast growth factor to the stroke cavity 7 days after ischemic stroke in rats.The gel slowly released basic fibroblast growth factor,which improved the local microenvironment,activated endogenous neural stem/progenitor cells,and recruited these cells to migrate toward the penumbra and stroke cavity and subsequently differentiate into neurons,while enhancing angiogenesis in the penumbra and stroke cavity and ultimately leading to partial functional recovery.This study revealed the mechanism by which bioactive materials repair ischemic strokes,thus providing a new strategy for the clinical application of bioactive materials in the treatment of ischemic stroke.

Effectiveness and safety of seven oral Chinese patent medicines as adjuvant therapy for cancer-related anemia: A systematic review and network meta-analysis of randomized controlled trials

Objective:To evaluate the effectiveness and safety of seven oral Chinese patent medicines(CPMs)as adjuvant therapy for cancer-related anemia(CRA)by network meta-analysis(NMA).Methods:A literature search to obtain randomized controlled trials(RCTs)of seven oral CPMs in the adjuvant treatment of CRA was conducted in multiple databases from the inception to April 2022.The RevMan5.3 and R 4.1.1 software were used for NMA.Results:We ultimately included 29 RCTs with 2140 patients.Traditional meta-analysis showed that Fufang E'jiao syrup(FFEJS),Shengxuebao mixture(SXBM),Shengxuening tablets(SXNT),Jianpi Shengxue granules(JPSXG),and Yixuesheng capsule(YXSC)combined with basic Western treatment(BWT)could improve the hemoglobin(HGB)level.JPSXG combined with BWT could improve the red blood cell(RBC).FFEJS combined with BWT improved the Karnofsky performance status(KPS).NMA showed that FFEJS,JPSXG,SXBM,and SXNT plus BWT improved HGB better than Shengxue tablets(SXT)plus BWT,with top three ranking results being JPSXG plus BWT>SXNT plus BWT>FFEJS plus BWT.FFEJS plus BWT,JPSXG plus BWT,SXBM plus BWT,SXNT plus BWT,and SXT plus BWT improved RBC better than BWT,with top three ranking results being SXNT plus BWT>JPSXG plus BWT>FFEJS plus BWT.In terms of the KPS score,compared with SXT plus BWT,FFEJS,JPSXG,SXBM,SXNT,and Yizhong Shengxue capsule(YZSXC)plus BWT had higher KPS,with top three ranking results being SXBM plus BWT>JPSXG plus BWT>FFEJS plus BWT.Conclusions:Our NMA demonstrated that seven oral CPMs used as adjuvant treatment of CRA had a definite clinical effect.JPSXG not only increases the levels of HGB and RBC to enhance the clinical effect but also improves patients'quality of life.More accurate conclusions need to be verified by more high-quality RCTs.

Objective:To investigate the in vitro antioxidant and wound healing properties of the hydroethanolic extract of Sargassum polycystum,and elucidate the mechanism of its wound healing activity.Methods:Human dermal fibroblast and HaCaT cells were used to evaluate the proliferation by sulforhodamine B and dsDNA assay after treatment with Sargassum polycystum extracts.Scratch wound healing and phalloidin-rhodamine staining were employed to observe migratory activity and filopodia formation,respectively.Western blot and real-time RT-PCR assays were performed to determine the protein and gene expressions related to wound healing activities.Results:The phytochemical analysis found a higher level of flavonoid than phenolic compound in Sargassum polycystum extracts.In human dermal fibroblast cells,Sargassum polycystum extracts at 50 and 100μg/mL significantly increased fibroblast proliferation and the gene expressions of hyaluronic acid synthase 1(HAS1),HAS2,HAS3,collagen type 1 alpha 1 chain(COL1A1),collagen type 3 alpha 1 chain(COL3A1),and elastin.The phosphorylation of Akt,ERK1/2,and p38 MAPK was also significantly upregulated after treatment with Sargassum polycystum extracts.Additionally,50 and 100μg/mL of the extracts prominently enhanced the proliferation,migration,and filopodia formation of HaCaT cells,as well as the protein levels of pFAK/FAK,pSrc/Src,pAkt/Akt,pERK1/2/ERK1/2,Rac1 and Cdc42.Conclusions:Sargassum polycystum extracts show promising wound healing activities in human dermal fibroblasts and keratinocytes.

Bone marrow mesenchymal stem cell-derived exosomal microRNAs target PI3K/Akt signaling pathway to promote the activation of fibroblasts

BACKGROUND Fibroblast plays a major role in tendon-bone healing.Exosomes derived from bone marrow mesenchymal stem cells(BMSCs)can activate fibroblasts and promote tendon-bone healing via the contained microRNAs(miRNAs).However,the underlying mechanism is not comprehensively understood.Herein,this study aimed to identify overlapped BMSC-derived exosomal miRNAs in three GSE datasets,and to verify their effects as well as mechanisms on fibroblasts.AIM To identify overlapped BMSC-derived exosomal miRNAs in three GSE datasets and verify their effects as well as mechanisms on fibroblasts.METHODS BMSC-derived exosomal miRNAs data(GSE71241,GSE153752,and GSE85341)were downloaded from the Gene Expression Omnibus(GEO)database.The candidate miRNAs were obtained by the intersection of three data sets.TargetScan was used to predict potential target genes for the candidate miRNAs.Functional and pathway analyses were conducted using the Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)databases,respectively,by processing data with the Metascape.Highly interconnected genes in the protein-protein interaction(PPI)network were analyzed using Cytoscape software.Bromodeoxyuridine,wound healing assay,collagen contraction assay and the expression of COL I andα-smooth muscle actin positive were applied to investigate the cell proliferation,migration and collagen synthesis.Quantitative real-time reverse transcription polymerase chain reaction was applied to determine the cell fibroblastic,tenogenic,and chondrogenic potential.RESULTS Bioinformatics analyses found two BMSC-derived exosomal miRNAs,has-miR-144-3p and hasmiR-23b-3p,were overlapped in three GSE datasets.PPI network analysis and functional enrichment analyses in the GO and KEGG databases indicated that both miRNAs regulated the PI3K/Akt signaling pathway by targeting phosphatase and tensin homolog(PTEN).In vitro experiments confirmed that miR-144-3p and miR-23b-3p stimulated proliferation,migration and collagen synthesis of NIH3T3 fibroblasts.Interfering with PTEN affected the phosphorylation of Akt and thus activated fibroblasts.Inhibition of PTEN also promoted the fibroblastic,tenogenic,and chondrogenic potential of NIH3T3 fibroblasts.CONCLUSION BMSC-derived exosomes promote fibroblast activation possibly through the PTEN and PI3K/Akt signaling pathways,which may serve as potential targets to further promote tendon-bone healing.

Areca nut is used worldwide as a hallucinogenic addicting drug along the tropical belt.Arecoline,a toxic compound,is the most important alkaloid in areca nuts.The adverse effects of oral uptake and chewing of areca nut are well known.For example,the possibility of cancer caused by chewing areca nuts is widely discussed.Chewing areca nut has other adverse effects on other organs,including abnormal cell differentiation,oral cancer,and several other diseases.The use of areca nut is also associated with low birthweight.Skeletal musculature is the largest organ in the body and is attached to the bones.During embryo development,the differentiation of bone and muscle cells is critical.In this article,we reviewed the effects of areca nut and arecoline on embryonic cell differentiation,particularly osteoblasts,myoblasts,and fibroblasts.

Cancer-associated fibroblasts of colorectal cancer: Translationalprospects in liquid biopsy and targeted therapy

Colorectal cancer (CRC) is a major global health concern. Accumulation of cancer-associated fibroblasts(CAFs) in CRC is associated with poor prognosis and disease recurrence. CAFs are the main cellular component ofthe tumor microenvironment. CAF-tumor cell interplay, which is facilitated by various secretomes, drives colorectalcarcinogenesis. The complexity of CAF populations contributes to the heterogeneity of CRC and influences patientsurvival and treatment response. Due to their significant roles in colorectal carcinogenesis, different clinicalapplications utilizing or targeting CAFs have been suggested. Circulating CAFs (cCAFs) which can be detected inblood samples, have been proposed to help in determining patient prognosis and enables the detection of cancerthrough liquid biopsy. Liquid biopsy is gaining traction as it is non-invasive, allows frequent and easy sampling, andshows concordance to tissue biopsy analysis. In addition, CAF-targeted therapy is currently being studied extensivelyto be used as one of the treatment avenues for CRC. Various mechanisms of CAF-targeted therapy have beenreported, including blocking the signaling pathways involving CAFs and cancer cells, thus abolishing the CAF-tumorcell crosstalk and subsequently hindering tumorigenesis. These translational applications of cCAFs and utilization ofCAFs as key targets for CRC therapy, although still in the early phases of development, will potentially improve CRCpatient management in the future.

METTL14 upregulates m6A modification of pri‑miR‑141 inhibiting ZEB1 to promote proliferation and inflammation of lung fibroblasts

Objective: To explore whether METTL14 is involved in regulating the fibroblast proliferation and inflammatory cytokine secretion by regulating the m6A modification of pri‑miR‑141. Methods: MRC‑5 cells were transfected via METTL14 overexpression lentivirus to increase METTL14 expression. Levels of METTL14 and ZEB1 were measured by qPCR and western blot. The effect of METTL14 on MRC‑5 proliferation and apoptosis was determined by CCK‑8 and flow cytometry, respectively. The ELISA kits of IL‑2, IL6 and TNF‑α were used to detect the effect of METTL14 on MRC‑5 inflammatory secretion. m6A modification site on pri‑miR‑141 was detected by meRIP. The binding site between pri‑miR‑141 and METTL14 was determined by RIP. Results: We successfully upregulated METTL14 expression in MRC‑5 cells. Elevated METTL14 promoted MRC‑5 cell proliferation, suppressed its apoptosis and promoted inflammatory factors secretion in MRC‑5 cells. pri‑miR‑141 had m6A modification sites. pri‑miR‑141 can directly bind to METTL14. METTL14 upregulation increased miR‑141 while suppressed ZEB1 expression. Conclusion: METTL14 can promote the expression of miR‑141 by increasing the m6A modification site of pri‑miR‑141, and inhibit ZEB1, thereby promoting the proliferation of fibroblasts and the secretion of inflammatory factors.

Background:Rehmanniae Radix Praeparata(RRP,Shu Dihuang in Cinese)is a traditional Chinese herb with multiple pharmacological effects and is commonly used to treat blood deficiency syndrome,such as cancer-related anemia(CRA),alone or in combination with other herbs.However,its main active ingredients and mechanisms of action in treating CRA remain unknown.This study aims to elucidate RRP’s potential mechanism and main active components in treating CRA by using network pharmacology and molecular docking technology system.Methods:The main components of RRP were obtained by the TCMSP database and literature search,and active components and potential targets were obtained by the SwissADME and SwissTargetPridiction databases.CRA targets were collected through GeneCards,DisGeNET,and DrugBank databases.Protein-protein interaction networks of potential targets were constructed via STRING 11.5 and analyzed visually with Cytoscape 3.9.1.The Metascape platform was used for Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analysis,which were subsequently visualized with Cytoscape 3.9.1 or SangerBox platform.Moreover,Autodock Vina was used for the molecular docking of potential targets and main active ingredients that were visualized with PyMOL software.Results:In this study,31 main active ingredients of PPR were screened,and 155 related targets related to CRA were unearthed.Protein-protein interaction results showed that PPR’s core proteins for CRA intervention correlate to STAT3,SRC,MAPK3,MAPK1,PIK3R1,PIK3CA,and AKT.Multiple signaling pathways were closely related to the treatment of CRA intervened by PPR,including the PI3K-Akt signaling pathway,HIF-1 signaling pathway,JAK-STAT3 signaling pathway,TNF-αsignaling,cytokine signaling pathway and NF-kappB signaling pathway,which are closely involved in the proliferation and differentiation of hematopoietic stem cell and inflammatory response.Molecular docking results showed that these potential targets had good conformation with the core active components of RRP for treating CRA.Conclusion:This study revealed RRP’s main active components and potential molecular mechanisms in treating CRA,providing a reference for subsequent basic research.

Uniportal video-assisted thoracoscopic fissureless right upper lobe anterior segmentectomy for inflammatory myofibroblastic tumor:A case report

BACKGROUND Inflammatory myofibroblastic tumors(IMTs)are exceptionally rare neoplasms with intermediate malignant potential.Surgery is the accepted treatment option,aiming for complete resection with clear margins.CASE SUMMARY A 39-year-old woman presented with a growing solitary pulmonary nodule measuring 2.0 cm in the right upper lobe(RUL)of the lung.The patient underwent a RUL anterior segmentectomy using uniportal video-assisted thoracoscopy.A preliminary tissue diagnosis indicated malignancy;however,it was later revised to an IMTs.Due to the absence of a minor fissure between the right upper and middle lobes,an alternative resection approach was necessary.Therefore,we utilized indocyanine green injection to aid in delineating the intersegmental plane.Following an uneventful recovery,the patient was discharged on the third postoperative day.Thereafter,annual chest tomography scans were scheduled to monitor for potential local recurrence.CONCLUSION This case underscores the challenges in diagnosing and managing IMTs,showing the importance of accurate pathologic assessments and tailored surgical strategies.

Fibroblast growth factor 21 inhibits ferroptosis following spinal cord injury by regulating heme oxygenase-1

Interfering with the ferroptosis pathway is a new strategy for the treatment of spinal cord injury.Fibroblast growth factor 21 can inhibit ferro ptosis and promote neurofunctional recovery,while heme oxygenase-1 is a regulator of iron and reactive oxygen species homeostasis.The relationship between heme oxygenase-1and ferroptosis remains controve rsial.In this study,we used a spinal co rd injury rat model to show that the levels of fibroblast growth factor 21 in spinal co rd tissue decreased after spinal cord injury.In addition,there was a significant aggravation of ferroptosis and a rapid increase in heme oxygenase-1 expression after spinal cord injury.Furthe r,heme oxygenase-1 aggravated fe rroptosis after spinal cord injury,while fibroblast growth factor 21 inhibited fe rroptosis by downregulating heme oxygenase-1.Thus,the activation of fibroblast growth factor 21 may provide a potential treatment for spinal co rd injury.These findings could provide a new potential mechanistic explanation for fibroblast growth factor 21 in the treatment of spinal cord injury.

Roles of fibroblast growth factors in the treatment of diabetes

Diabetes affects about 422 million people worldwide,causing 1.5 million deaths each year.However,the incidence of diabetes is increasing,including several types of diabetes.Type 1 diabetes(5%-10%of diabetic cases)and type 2 diabetes(90%-95%of diabetic cases)are the main types of diabetes in the clinic.Accumulating evidence shows that the fibroblast growth factor(FGF)family plays important roles in many metabolic disorders,including type 1 and type 2 diabetes.FGF consists of 23 family members(FGF-1-23)in humans.Here,we review current findings of FGFs in the treatment of diabetes and management of diabetic complications.Some FGFs(e.g.,FGF-15,FGF-19,and FGF-21)have been broadly investigated in preclinical studies for the diagnosis and treatment of diabetes,and their therapeutic roles in diabetes are currently under investigation in clinical trials.Overall,the roles of FGFs in diabetes and diabetic complications are involved in numerous processes.First,FGF intervention can prevent high-fat diet-induced obesity and insulin resistance and reduce the levels of fasting blood glucose and triglycerides by regulating lipolysis in adipose tissues and hepatic glucose production.Second,modulation of FGF expression can inhibit renal and cardiac fibrosis by regulating the expression of extracellular matrix components,promote diabetic wound healing process and bone repair,and inhibit cancer cell proliferation and migration.Finally,FGFs can regulate the activation of glucoseexcited neurons and the expression of thermogenic genes.

Attenuation of the Activation of NLRP3 Inflammasome in Fibroblast Like Synoviocytes of Rheumatoid Arthritis by Baicalin through Regulating the Let-7i-3p/PI3K/Akt/NF-κB Signaling Axis

[Objectives]To study the effect and mechanism of baicalin on the activation of NLRP3 inflammasome in human fibroblast like synoviocytes of rheumatoid arthritis(HFLS-RA).[Methods]To confirm that baicalin alleviated the activation of NLRP3 inflammasome in HFLS-RA,the expression of NLRP3 before and after baicalin treatment was observed by immunofluorescence.Western blot was used to detect the protein expression of p-PI3K,p-Akt,NF-κB p65,NLRP3,ASC and caspase-1 after baicalin treatment for 48 h,and the contents of IL-1 and IL-18 in the supernatents were detected by ELISA.In order to explore the mechanism of baicalin alleviating the activation of NLRP3 inflammasome,the corresponding relationship between let-7i-3p and PIK3CA was verified by double luciferin and Westen blot analysis.The expression of let-7i-3p and PI3K before and after baicalin intervention was detected by RT-qPCR.let-7i-3p interference was used to verify whether baicalin mitigated the activation of enhanced NLRP3 inflammasome.[Results]Baicalin(50 and 100 mg/L)significantly reduced the activation of NLRP3 inflammasome,inhibited the protein expressions of p-PI3K,p-Akt,NF-κB p65,NLRP3,ASC and caspase-1,and the secretion of IL-1 and IL-18.let-7i-3p and PIK3CA had a targeted correspondence,and baicalin up-regulated the expression of let-7i-3p and down-regulated the expression of PIK3CA.Baicalin attenuated the activation of NLRP3 inflammasome enhanced by let-7i-3p interference.[Conclusions]Baicalin can up-regulate let-7i-3p expression,inhibit PI3K/Akt/NF-κB signal transduction,and thus reduce the activation of NLRP3 inflammasome in HFLS-RA.
