Diabetes has long been considered a risk factor in implant therapy and impaired wound healing in soft and hard oral tissues.Magnesium has been proved to promote bone healing under normal conditions.Here,we elucidate the mechanism by which Mg^(2+)promotes angiogenesis and osseointegration in diabetic status.We generated a diabetic mice model and demonstrated thealveolar bone healing was compromised,with significantly decreased angiogenesis.We then developed Mg-coating implants with hydrothermal synthesis.These implants successfully improved the vascularization and osseointegration in diabetic status.Mechanically,Mg^(2+)promoted the degradation of Kelch-like ECH-associated protein 1 (Keap1) and the nucleation of nuclear factor erythroid 2-related factor 2 (Nrf2) by up-regulating the expression of sestrin 2 (SESN2) in endothelial cells,thus reducing theelevated levels of oxidative stress in mitochondria and relieving endothelial cell dysfunction under hyperglycemia.Altogether,our data suggested that Mg^(2+)promoted angiogenesis and osseointegration in diabetic mice by regulating endothelial mitochondria metabolism.

The liver is an important metabolic and detoxification organ and hence demands a large amount of energy,which is mainly produced by the mitochondria.Liver tissues of pa-tients with alcohol-related or non-alcohol-related liver diseases contain ultrastructural mito-chondrial lesions,mitochondrial DNA damage,disturbed mitochondrial dynamics,and compromised ATP production.Overproduction of mitochondrial reactive oxygen species in-duces oxidative damage to mitochondrial proteins and mitochondrial DNA,decreases mito-chondrial membrane potential,triggers hepatocyte inflammation,and promotes programmed cell death,all of which impair liver function.Mitochondrial DNA may be a poten-tial novel non-invasive biomarker of the risk of progression to liver cirrhosis and hepatocellular carcinoma in patients infected with the hepatitis B virus.We herein present a review of the mechanisms of mitochondrial dysfunction in the development of acute liver injury and chronic liver diseases,such as hepatocellular carcinoma,viral hepatitis,drug-induced liver injury,alcoholic liver disease,and non-alcoholic fatty liver disease.This review also discusses mito-chondrion-centric therapies for treating liver diseases.

Liver disease,a major health concern worldwide,is a serious and progressive disorder.Herein,we not only established a mouse model of DEN+CCl4-induced primary liver disease but also collected clinical human samples to investigate longitudinal alterations in the gut mycobiome.As liver disease advanced,gut integrity was disrupted,and the mycobiota was disturbed in the mouse models.The metabolites associated with hepatocellular carcinoma(HCC)differed from those associated with the cirrhotic phase as follows:levels of stercobilin and aflatoxin B1 dialcohol were reduced,while levels of triterpenoids,bafilomycin A1,and DHEA were increased in the HCC group.The abundance of the phylum Chytridiomycota increased as the chronic liver disease progressed and was then replaced by the phylum Ascomycota in HCC.Based on the results from clinical human samples,the genus Candida(Ascomycota)(in humans)and the genus Kazachstania(Ascomycota)(in mice)occupied a dominant position in the HCC group,while other fungi were depleted.The increased abundance of C.albicans and depletion of S.cerevisiae may be hallmarks of the progression of liver cirrhosis to early HCC.Moreover,the administration of C.albicans and S.cerevisiae in the LC-HCC progression could accelerate or retard the progression of HCC.Therefore,gut fungi have the potential to serve as a noninvasive clinical biomarker and even a treatment method.

Lipocalin 2(LCN2)plays a pivotal role in iron metabolism,particularly in the context of microbial infection resistance(e.g.,viruses,bacteria,parasites,etc.).LCN2 combats microbial infection by directly assisting the body in competing with microorganisms for iron,inducing immune cells to secrete various cytokines to enhance systemic immune responses,or recruiting neutrophils to infectious sites.The liver serves as the primary organ for LCN2 secretion during microbial infections.This review encapsulates recent advances in dynamic changes,clinical values,and the effects of LCN2 in infectious liver diseases caused by various microbial microorganisms.

Background:Hepatocellular carcinoma(HCC)has a poor long-term prognosis.The competition of circular RNAs(circRNAs)with endogenous RNA is a novel tool for predicting HCC prognosis.Based on the alterations of circRNA regulatory networks,the analysis of gene modules related to HCC is feasible.Methods:Multiple expression datasets and RNA element targeting prediction tools were used to construct a circRNA-microRNA-mRNA network in HCC.Gene function,pathway,and protein interaction analyses were performed for the differentially expressed genes(DEGs)in this regulatory network.In the proteinprotein interaction network,hub genes were identified and subjected to regression analysis,producing an optimized four-gene signature for prognostic risk stratification in HCC patients.Anti-HCC drugs were excavated by assessing the DEGs between the low-and high-risk groups.A circRNA-microRNA-hub gene subnetwork was constructed,in which three hallmark genes,KIF4A,CCNA2,and PBK,were subjected to functional enrichment analysis.Results:A four-gene signature(KIF4A,CCNA2,PBK,and ZWINT)that effectively estimated the overall survival and aided in prognostic risk assessment in the The Cancer Genome Atlas(TCGA)cohort and International Cancer Genome Consortium(ICGC)cohort was developed.CDK inhibitors,PI3K inhibitors,HDAC inhibitors,and EGFR inhibitors were predicted as four potential mechanisms of drug action(MOA)in high-risk HCC patients.Subsequent analysis has revealed that PBK,CCNA2,and KIF4A play a crucial role in regulating the tumor microenvironment by promoting immune cell invasion,regulating microsatellite instability(MSI),and exerting an impact on HCC progression.Conclusions:The present study highlights the role of the circRNA-related regulatory network,identifies a four-gene prognostic signature and biomarkers,and further identifies novel therapy for HCC.

Acute liver failure(ALF)is a life-threatening condition that manifests in an extremely serious manner and progresses rapidly.The following study investigated the protective effect of astragaloside IV(AS-IV),a traditional Chinese drug,on ALF,and its underlying mechanisms,focusing on autophagy and inflammation regulation.Mice were randomly divided into a saline group,a D-galactosamine and lipopolysac-charide(D-GalN/LPS)group and an AS-IV group.Biochemical analysis,immunohistochemistry,cytometric bead array,high-throughput quantitative PCR,flow cytometry and Western analysis were used to assess inflammation and liver damage 5 hours after D-GalN/LPS ex-posure.Astragaloside IV treatment reduced mortality by alleviating D-GalN/LPS–induced hepatic damage and decreasing inflammation(decreasing Ly6c+monocyte levels,reducing inflammatory cytokines and increasing anti-inflammatory factors)as well as upregulating au-tophagy.Furthermore,PCR array was used to detect expression of autophagy-related genes,which demonstrated a Log2 fold change in gene expression between the AS-IV and D-GalN/LPS groups ranging from 1.19 to-3.53,with Tnfsf10 showing the largest alteration be-tween the two groups.These data suggest that AS-IV may alleviate ALF by upregulating autophagy and reducing inflammation,and it may therefore be an interesting drug for alleviating ALF.
