Ulva prolifera green tides are becoming aworldwide environmental problem,especially in the Yellow Sea,China.However,the effects of the occurrence of U.prolifera green tides on the community organization and stability of surrounding microbiomes have still not been de-termined.Here,the prokaryotic microbial community network stability and assembly char-acteristics were systematically analyzed and compared between the green tide and non-green tide periods.U.prolifera blooms weaken the community complexity and robustness of surrounding microbiomes,increasing fragmentation and decreasing diversity.Bacteria and archaea exhibited distinct community distributions and assembly patterns under the influ-ence of green tides,and bacterial communities were more sensitive to outbreaks of green tides.The bacterial communities exhibited a greater niche breadth and a lower phyloge-netic distance during the occurrence of U.prolifera green tides compared to those during the non-green tide period while archaeal communities remained unchanged,suggesting that the bacterial communities underwent stronger homogeneous selection and more sensitive to green tide blooms than the archaeal communities.Piecewise structural equation model analysis revealed that the different responses of major prokaryotic microbial groups,such as Cyanobacteria,to environmental variables during green tides,were influenced by the variations in pH and nitrate during green tides and correlated with the salinity gradient during the non-green tide period.This study elucidates the response of the adaptability,associations,and stability of surrounding microbiomes to outbreaks of U.prolifera green tides. 展开更多

Compared with the rice-acid soup inoculated with single starter,the synergistically intensifi ed rice-acid soup inoculated with Lactobacillus paracasei H4-11(L.paracasei H4-11)and Kluyveromyces marxianus L1-1(K.marxianus L1-1)contained more fl avor compounds.Organic acids mainly included L-lactic acid and the main volatile fl avor component was ethyl acetate.Moreover,the signal intensity of astringency and bitterness and the total concentration of volatile sulfur compounds were reduced.The combined analysis results of RNA sequencing(RNA-seq)technology and 4D label-free quantitative(4D LFQ)proteomics explained the fl avor formation pathways in rice-acid soup inoculated with L.paracasei H4-11 and K.marxianus L1-1.In L.paracasei H4-11,L-lactate dehydrogenase,phosphoglucomutase,acetate kinase,alcohol dehydrogenase and acetyl-CoA were up-regulated and D-lactate dehydrogenase and N-Acetyltransferase were down-regulated.In K.marxianus L1-1,Acetyl-CoA,acetaldehyde dehydrogenase,acyl-coenzyme A,N-acetyltransferase,and L-lactate dehydrogenase were up-regulated and hexokinase,alcohol dehydrogenase,and alcohol O-acetyltransferase were down-regulated.The above up-regulation and down-regulation synergistically promoted the formation of characteristic fl avor compounds(mainly L-lactic acid and ethyl acetate).Enzyme-linked immunoassay(ELISA)and parallel reaction monitoring(PRM)quantitative analysis respectively verifi ed that 5 key metabolic enzymes and 27 proteins in L.paracasei H4-11 and K.marxianus L1-1 were associated with the characteristic fl avor of rice-acid soup,as confi rmed by the quantitative results of 4D LFQ. 展开更多

OBJECTIVE: To confirm the anti-NPC effect of sanguinarine(SA) through a series of wet experiments.METHODS: NPC cell viability was determined by proliferation experiment. Cell clone formation experiment, cell scratch test, transwell migration and invasion experiment and flow cytometry-based cell apoptosis assay were further performed. In addition, Western blotting was performed to investigate the cell signaling pathway. All the relevant experimental data were statistically processed using SPSS 16.0 software.RESULTS: The results showed that sanguinarine represented a time and dose dependent inhibition effects on NPC cell proliferation including the low differentiated CNE2 cells and high metastatic 5-8F cells, along with the cell cloning ability reduction. In addition, sanguinarine has a certain inhibitory effect on the invasion and migration of NPC cells. Mechanistically, sanguinarine displayed the anti-NPC effects mainly involved into the suppression of m TOR signaling and cell apoptosis, which is closely associated with the tumor growth and metastatic malignancy. CONCLUSIONS: Collectively, we discover that sanguinarine is a new high-efficiency anti-NPC monomer of Chinese medicine, with a value for the follow-up preclinical research. 展开更多

Environmental changes along an altitudinal gradient can facilitate the differentiation of life-history features in ectothermic species,but little attention has been devoted to the reciprocal influence of altitude and alpine slope directionality on life-history variation.According to life-history theory,increased environmental stress causes a change in reproductive allocation from number to quality of offspring,as well as a stronger trade-off between size and number of offspring.To clarify the influence of environmental pressures on the life-history features of the Qinghai toad-headed lizard Phrynocephalus vlangalii along an altitudinal cline,we surveyed late pregnant females from 3 populations of low(2,600 m),middle(3,400 m),and high(3,600 m)elevations in the Dangjin Mountain of Gansu,China from July to October 2019,and compared their inter-population differences in maternal body size,reproductive characteristics,offspring growth,and locomotor performance.Because of lower temperatures,higher humidity,and lower light intensity caused by slope aspect and altitude,the middle-altitude region experienced stronger environmental stress than the high-and low-altitude regions.Our results showed that females were larger at middle-and high-altitude sites and smaller at the low-altitude site,following Bergmann’s rule.We also found that females from low-altitude population gave birth earlier than those from the middle and high altitudes.Our results showed a shift in the offspring size-number trade-off of P.vlangalii in response to colder and harsher environments,with lizards from the alpine steppe(i.e.the middle-and high-altitude habitats)producing fewer but larger offspring than those from the warm steppe(i.e.the low-altitude habitat).Low-altitude juveniles grew faster than high-altitude ones,but at the same rates as middle-altitude juveniles.This result demonstrates that the growth of P.vlangalii was associated with temperature and light intensity.Our findings contribute to enhancing our understanding of the altitudinal variation in life-history features of plateau ectotherms and their phenotypic plasticity or local adaptation. 展开更多

Background:We aimed to explore the associations of adherence to an overall healthy lifestyle with cardiometabolic diseases(CMDs)among schoolteachers in China.Methods:We conducted a cross-sectional analysis among 2983 teachers(aged 39.8±9.3 years,73.8%women)in Zhejiang Province,China.A healthy lifestyle score(0–7)was constructed based on seven low-risk factors:healthy diet,noncurrent smoking,noncurrent drinking,regular exercise,normal body mass index(BMI),adequate sleep duration,and limited sedentary behavior.CMDs included self-reported hyperlipidemia,hypertension,diabetes,coronary heart disease,and stroke.Multivariable-adjusted logistic regression models were used to evaluate the associations between healthy lifestyle and CMD.Results:A total of 493(16.5%)participants had at least one CMD,with hyperlipidemia,hypertension,and diabetes being the three leading CMDs.ach point increment in a healthy lifestyle score was associated with 20%lower odds of having CMD(p-trend<0.001).Compared with 0–3 low-risk factors,the odds ratios(ORs)and 95%confidence intervals(CIs)were 0.66(0.50–0.88)for 4 low-risk factors and 0.51(0.39–0.67)for 5–7 low-risk factors.We observed independent associations for normal BMI(OR=0.50,95%CI=0.40–0.63),noncurrent drinking(OR=0.53,95%CI=0.36–0.77),and limited sedentary behavior(OR=0.77,95%CI=0.62–0.96)in relation to CMD.Healthy diet(OR=0.75,95%CI=0.55–1.01)exhibited marginally significant association with CMD.Conclusions:Our findings suggest that adherence to an overall healthy lifestyle is associated with lower odds of CMD among schoolteachers. 展开更多

Parkinson's disease(PD),a chronic and com-mon neurodegenerative disease,is characterized by the progressive loss of dopaminergic neurons in the dense part of the substantia nigra and abnormal aggregation of alpha-synuclein.Type 2 diabetes mellitus(T2DM)is a metabolic disease characterized by chronic insulin resistance and deficiency in insulin secretion.Extensive evidence has con-firmed shared pathogenic mechanisms underlying PD and T2DM,such as oxidative stress caused by insulin resistance,mitochondrial dysfunction,inflammation,and disorders of energy metabolism.Conventional drugs for treating T2DM,such as metformin and glucagon-like peptide-1 receptor ago-nists,affect nerve repair.Even drugs for treating PD,such as levodopa,can affect insulin secretion.This review sum-marizes the relationship between PD and T2DM and related therapeutic drugs from the perspective of insulin signaling pathways in the brain. 展开更多

To explore the mechanism of sperm dysfunction caused by dibutyl phthalate(DBP),the effects of DBP on intracellular[Ca^(2+)]and[pH],reactive oxygen species(ROS),lipid peroxidation(LPO),mitochondrial permeability transition pore(mPTP)opening,mitochondrial membrane potential(MMP),adenosine triphosphate(ATP)levels,phosphorylation of protein kinase A(PKA)substrate proteins and phosphotyrosine(p-Tyr)proteins,sperm motility,spontaneous acrosome reaction,and tail bending were examined in mouse spermatozoa.At 100μg/mL,DBP significantly increased tail bending and[Ca^(2+)]i.Interestingly,DBP showed biphasic effects on[pH]i.DBP at 10–100μg/mL significantly decreased sperm motility.Similarly,Ca^(2+)ionophore A23187 decreased[pH]_(i)sperm motility,suggesting that DBP-induced excessive[Ca^(2+)]_(i)decreased sperm motility.DBP significantly increased ROS and LPO.DBP at 100μg/mL significantly decreased mPTP closing,MMP,and ATP levels in spermatozoa,as did H2O2,indicative of ROS-mediatedmitochondrial dysfunction caused by DBP.DBP as well as H2O2 increased p-Tyr sperm proteins and phosphorylated PKA substrate sperm proteins.DBP at 1–10μg/mL significantly increased the spontaneous acrosome reaction,suggesting that DBP can activate sperm capacitation.Altogether,DBP showed a biphasic effect on intracellular signaling in spermatozoa.At concentrations relevant to seminal ortho-phthalate levels,DBP activates[pH]i,protein tyrosine kinases and PKA via physiological levels of ROS generation,potentiating sperm capacitation.DBP at high doses excessively raises[Ca^(2+)]_(i)and ROS and disrupts[pH]i,impairing the mitochondrial function,tail structural integrity,and sperm motility. 展开更多

Hippo signaling is a highly conserved pathway central to diverse cellular processes.Dysregulation of this pathway not only leads to developmental abnormalities but is also closely related to the occurrence and progression of various cancers.Recent studies have uncovered that,in addition to the classical signaling cascade regulation,biomolecular condensates formed via phase separation play a key role in the spatiotemporal regulation of Hippo signaling.In this review,we provide a summary of the latest research progress on the regulation of the Hippo signaling pathway by phase separation,with a particular focus on transcriptional activation mediated by Yes-associated protein(YAP)/transcriptional coactivator with post-synaptic density-95,disks-large,and zonula occludens-1(PDZ)-binding domain(TAZ)condensates.Furthermore,we discuss the utility of chemical crosslinking combined with mass spectrometry to analyze the TAZ condensate interactome and examine the role of the protein fused in sarcoma(FUS)in modulating the biophysical properties of TAZ condensates,which in turn influence their transcriptional activity and pro-tumorigenic functions.These insights not only advance our understanding of Hippo signaling but also offer new perspectives for therapeutic interventions targeting diseases linked to dysregulated YAP/TAZ activity. 展开更多

Lupus nephritis(LN)is one of the most common and serious complications of systemic lupus erythematosus,which can lead to end-stage renal disease,and is an important cause of death in patients with systemic lupus erythematosus.Treatment options include glucocorticoids,immunosuppressive agents and the addition of biologics.Recently,the therapeutic role of mesenchymal stem cells(MSCs)in LN has received extensive attention worldwide.MSCs can suppress autoimmunity,alleviate proteinuria and restore renal function by modulating the functions of various immune cells and reducing the secretion of inflammatory cytokines.Several clinical trials have investigated MSC treatment in LN with promising but sometimes inconsistent outcomes.This review summarizes the sources of MSCs and mechanisms in immunoregulation.Furthermore,it examines clinical trials evaluating the efficacy,safety,and limitations of MSC therapy in LN.By highlighting advances and ongoing challenges,this review underscores the potential of MSCs for LN treatment.More large-scale randomized controlled trials are needed to support the effectiveness of this therapy and pave the way for personalized and combinatorial therapeutic approaches. 展开更多

Infectious wound healing is complicated with and limited by infection and oxidative stress at the wound site.In recent years,various evidences suggest that nanozymes with multiple enzymatic activities have enabled the development of novel strategies for infectious wound healing.In this study,epigallocatechin gallate loaded polydopamine(P@E)was developed to act as a potent reactive oxygen species(ROS)scavenger for scavenging ROS,alleviating inflammatory responses,and promoting infectious wound healing.Combining with near infrared(NIR)irradiation,P@E presented excellent antibacterial ability of Escherichia coli(E.coli,93.6%)and methicillin-resistant Staphylococcus aureus(MRSA,87.6%).Specifically,P@E+NIR exhibited the most potent antioxidant,anti-inflammatory and cell proliferation behaviors through downregulating intracellular ROS levels(81.9%and 94.3%for NIH3T3 and RAW264.7 respectively)and inducible nitric oxide synthase(iNOS)expression level(55.7%),and up-regulating the expression levels of arginase-1(Arg-1,71.4%),heat shock protein 70(HSP70,48.6%)and platelet endothelial cell adhesion molecule(CD31,35.3%)compared to control group.Meanwhile,it also efficiently induced M2 directional polarization of lipopolysaccharide induced murine macrophages to achieve anti-inflammation,indicated by the down-regulation of CD86(86.2%),and up-regulation of CD206(85.6%).Significantly,it was also observed that P@E+NIR presented the excellent behaviors of inhibiting wound infection,alleviating wound inflammation,as well as promoting skin tissue repairing.Altogether,it has developed the strategy of using P@E combining with NIR irradiation for the synergistic enhanced healing of infectious skin wound,which can serve as a promising therapeutic strategy for its clinical treatment. 展开更多

Abiotic stresses,particularly salinity,pose a major threat to rice productivity,highlighting the need to identify novel genetic resources to improve stress tolerance.Gamma irradiation remains one of the most widely used tools breeding stress-tolerant plant varieties.In this study,we identified a salt-tolerant rice mutant,salt-insensitive TILLING line 4(sitl4),generated via gamma irradiation and linked its enhanced tolerance to a loss-of-function mutation in Oryza sativa protein acyltransferase for ABA response 1(OsPATA1),which encodes a DHHC-type palmitoyl acyltransferase.Functional analyses using both sitl4 and a CRISPR/Cas9-mediated OsPATA1-knockout line(ospata1)revealed that disruption of OsPATA1 leads to increased abscisic acid(ABA)accumulation and upregulation of ABA-responsive genes under salt stress conditions.We identified OsEULD1b,a previously uncharacterized Euonymus lectin(EUL)domaincontaining protein,as an interactor of OsPATA1.In sitl4 and ospata1,OsEULD1b displayed cytosolic retention,suggesting that its subcellular redistribution enhances its role in ABA-mediated stress signaling.Taken together,our findings demonstrate that OsPATA1 and OsEULD1b form a regulatory module that modulates the ABA-dependent salt stress responses in rice.These results provide new insights into the molecular mechanisms underlying abiotic stress tolerance and will help to identify potential genetic targets for developing stress-tolerant rice cultivars through molecular breeding or genome editing. 展开更多
