The study by Chen et al found that miR-136 plays an indispensable role in the inflammation-cancer transformation in gastric cancer(GC).The authors conducted in vivo and in vitro experiments and verified them in conjunction with functional and molecular mechanisms.Their key findings indicate that Helicobacter pylori(H.pylori)activated NF-κB/miR-136/PDCD11 axis to induce the growth of H.pylori-positive GC tumors.And miR-136 is markedly associated with characteristics related to the gastric mucosal histopathological,supporting its use as a diagnostic biomarker and a therapeutic target for early H.pylori-induced GC.Chronic inflammation is one of the important precancerous lesions.With the development of emerging technologies such as multi-omics technology,the pathways linking chronic inflammation to cancer have been extensively elucidated.In this letter,we focus on introducing the molecular mechanisms of chronic inflammation in the development of GC,which will provide new insights for early diagnosis,personalized treatment,and prognosis assessment of GC. 展开更多

Histone deacetylase inhibitors(HDACis),such as trichostatin A(TSA),have been recognized as promising anti-cancer agents due to their capacity to restore epigenetic regulation and reactivate tumor suppressor genes.However,emerging evidence indicates that unintended pro-metastatic effects may offset the therapeutic benefits of HDACis.Chen et al elucidate this paradox,demonstrating that TSA-induced hyperacetylation activates the BRD4/c-Myc/ER-stress axis,thereby promoting epithelial-mesenchymal transition and metastasis in esophageal squamous cell carcinoma(ESCC).Furthermore,they clarify the clinical significance of histone acetylation in the prognostic evaluation of ESCC.Their findings underscore the complexity of epigenetic therapies and highlight the necessity of reevaluating the associated risks and combinatorial therapeutic strategies with HDACi-based treatments.Here,we summarize the potential risks of HDACis therapy and discuss feasible combination therapeutic strategies. 展开更多

The proliferative index of Ki-67 in pancreatic ductal adenocarcinoma(PDAC)exhibits strong correlations with tumor progression and prognosis,holding significant clinical implications.Yang et al employed contrast-enhanced ultrasound(CEUS)to indirectly evaluate neovascularization in pancreatic cancer lesions.Specific CEUS parameters demonstrated significant diagnostic value in assessing Ki-67 expression.The falling slope 50%achieved an area under the curve of 0.838.Meanwhile,the rise slope 10%-90%exhibited superior overall diagnostic accuracy(area under the curve=0.863),showing a sensitivity of 0.92 and a moderate specificity of 0.759.These values demonstrate specificity in differentiating between low and high Ki-67 expression groups.This study effectively addresses the critical need for a non-invasive assessment of pancreatic cancer aggressiveness via Ki-67 expression.These findings strongly support the translational potential of CEUS biomarkers for non-invasive Ki-67 assessment and treatment stratification in PDAC.While Yang et al demonstrated exhibited encouraging methodologies,its retrospective design,modest sample size,and single-center nature may impede generalizability,pending validation in multi-institutional cohorts.We recommend expanding the sample size to enhance representativeness and adopting prospective studies integrating multimodal imaging techniques,such as magnetic resonance imaging and positron emission tomography to improve diagnostic reliability.This study is the first to integrate insights from CEUS,magnetic resonance imaging,and positron emission tomography for Ki-67 expression assessment in PDAC.Building on this innovation,we focus this article on recent advances in the clinical diagnosis of pancreatic cancer,aiming to provide insights for advancing research in this field. 展开更多

As a natural oil-soluble emulsifier to replace Polyglycerol Polyricinoleate(PGPR),lecithin's application in double emulsions(DEs)remains constrained due to low encapsulation efficiency and stability,while incorporating Pickering particles within the inner aqueous phase(W_(1))has emerged as an effective approach to enhance DEs stability.However,the interfacial interactions between Pickering particles in W_(1) and lecithin in oil phase and their effects on the physical,delivery and digestion properties of DEs remain to be explored.In this study,a natural Pickering DEs encapsulating blueberry anthocyanins(ANCs)was developed using lecithin and gliadinbased particles,with gliadin colloid particles(GCPs)introduced into W_(1).The effects of GCP concentration in W_(1) on emulsion droplet size,microstructure,W_(1)/O interfacial rheology,in vitro digestion,and ANCs delivery performance were systematically investigated.Results showed that GCPs in W_(1) accelerated the decreasing of W_(1)/O interfacial tension,indicating that,beyond competitive adsorption,combination between the two might also occur at the interface,which could accelerate the interfacial adsorption of lecithin.GCPs significantly improved the strength of the W_(1)/O interface,thus improving ANCs encapsulation efficiency from 49.66%to 70.60%.Moreover,the droplet size of DEs decreased from 38.94μm to 24.09μm as GCPs concentration increased,indicating that some GCPs might transfer to the outer aqueous phase through phase exchange,acting as hydrophilic emulsifiers.GCPs in W_(1) can modulate ANCs in vitro release,enhancing ANCs'bioaccessibility(31.10%)and antioxidant capacity. 展开更多

Plant-based milk is rich in polyunsaturated fatty acids,polyphenols and other bioactive compounds.This study investigated the effect of 3 plant-based milk(flaxseed milk,oat milk and soy milk)on the ceftriaxone-induced intestinal disorders,and compared the regulation patterns associated with gut microbiome and metabolome.The results showed plant-based milk alleviated the ceftriaxone caused cecum swelling,colonic tissue damage and intestinal microecological disorders.Meanwhile,administered plant-based milk decreased levels of pro-inflammatory cytokine(tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),interleukin-1β(IL-1β)and oxidative stresses(malondialdehyde(MDA)and myeloperoxidase(MPO)in the colon,as well as increasing the levels of tight junction proteins(Occludin,Claudin-1,and ZO-1)in the colon.Moreover,administration of plant-based milk modulated the intestinal microbiota by promoting the relative levels of beneficial bacteria(Bifidobacterium),and inhibiting the harmful bacteria genus(Enterococcus).Furthermore,plant-based milk treatment significantly modulated glycerophospholipids metabolism(e.g.glycerophosphocholine)and arachidonic acid metabolism(e.g.prostaglandin G2 and arachidonic acid)in the serum.In conclusion,plant-based milk could alleviate antibiotic-related imbalance of barrier function damage,gut microbiota disorders and the reduction of metabolic disorders,which lays a foundation for exploring anti-inflammatory and intestinal micro-ecological approach to plant-based milk. 展开更多

Chronic hepatitis B infection is caused by hepatitis B virus(HBV) and a total cure is yet to be achieved. The viral covalently closed circular DNA(ccc DNA) is the key to establish a persistent infection within hepatocytes. Current antiviral strategies have no effect on the pre-existing ccc DNA reservoir. Therefore, the study of the molecular mechanism of ccc DNA formation is becoming a major focus of HBV research. This review summarizes the current advances in ccc DNA molecular biology and the latest studies on the elimination or inactivation of ccc DNA, including three major areas:(1) epigenetic regulation of ccc DNA by HBV X protein,(2) immune-mediated degradation,and(3) genome-editing nucleases. All these aspects provide clues on how to finally attain a cure for chronic hepatitis B infection. 展开更多

This paper dealt with non-parallelism between the effect of microbial flocculant (MBF) on sewerage disposal and the flocculation rate, the high flocculation rate doesn’t mean the fine disposal effectiveness, and revealed the problem encountered when the exclusive parameter―flocculation rate is used to evaluate the effect of MBF on sewerage disposal. The results showed that MBF made from different carbon sources have some influence on the effectiveness of sewerage disposal; flocculation rate cannot authentically reflect the status of sewerage disposal. When the exclusive parameter―flocculation rate is used to evaluate the effect of MBF on sewerage disposal, it would be exaggerated, especially in disposing COD-low sewerage. The authors considered that when flocculation rate is used to evaluate the effect of MBF on sewerage disposal, it is better to take COD-removal rate into account. 展开更多

Colloidal mesoporous silica nanoparticles functionalized with carboxy-terminated polyethylene glycol(CMS-PEG-COOH) were successfully synthesized by covalently grafting dicarboxy-terminated polyethylene glycol(HOOC-PEG-COOH) on the surface of the amino functionalized CMS nanoparticles with amide bond as a cross linker. Moreover, the structural and particle properties of CMS-PEG-COOH were characterized by nuclear magnetic resonance spectroscopy(1 H-NMR), transmission electron microscopy(TEM), dynamic light scattering(DLS), nitrogen adsorption-desorption measurements, X-ray diffraction(XRD), and Fourier transform infrared spectroscopy(FT-IR). The nanomaterials presented a relatively uniform spherical shape morphology with diameters of about 120 nm,and favorable dispersibility in weak acid solution. The CMSPEG-COOH exhibited no changes in the state of amorphous, while the mesopores sizes of 5.25 nm might provide the nanomaterials with large capacity for the loading and releasing of drugs. So the results indicated that CMSPEG-COOH might be a critical nanomaterial for drug delivery system in the future. 展开更多

A mild chemistry route was developed to prepare carbonaceous nanofibers-titanium dioxide(CNF-TiO_2) nanocomposites for removal of dye pollutants. In the process of the template-directed hydrothermal carbonization(HTC), ultrathin Te nanowires were adopted as templates and glucose as the carbon source, and TiO_2 was decorated on CNF via the hydrolysis of tetrabutyltitanate in the presence of CNF in ethanol. The as-prepared materials were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM), energy-dispersive X-ray(EDX) and X-ray diffraction(XRD). SEM and TEM observations displayed that TiO_2 nanoparticles were anchored on the CNF. EDX and XRD data confirmed that the assynthesized samples were CNF-TiO_2, and TiO_2 belonged to anatase titania. Taking advantage of combined benefits of carbonaceous nanofibers and titanium dioxide, these CNF-TiO_2 nanocomposites exhibited higher removal efficiency in a short time and showed good reusability. It was showed that over 97% of Rhodamine B could be removed in 15 min without generating the solid and liquid wastes. The removal efficiency of dyes was still over 80% after reuse in five cycles. All the results demonstrate that the as-prepared CNF-TiO_2 composites are effective materials for fast and effective removal of dye pollutants and thus can provide a new platform for dye decontamination. 展开更多

The inhibitory activity of lactic acid bacteria(LAB)toward advanced glycation end-products(AGEs)during vinegar fermentation was studied,and its relationships with the substrate consumption,antioxidant capacity,total phenolic content,total flavonoid compounds,α-glucosidase,andα-amylase activity inhibition were evaluated.The vinegar was made from rice powder flour by liquid-state fermentation(LSF).The selected LAB strains were separately co-cultivated with Saccharomyces cerevisiae and Acetobacter pasteurianus 1.41 in alcoholic and acetic acid fermentation,respectively.Among 3 strains,Lactobacillus fermentum showed the strongest inhibitory effect on the formation of total fluorescent AGEs and carboxymethyl lysine(CML)/carboxyethyl lysine(CEL)in the fermentation process.The corresponding mechanisms included the acceleration of substrate consumtion,improvement of antioxidant activities,and inhibition ofα-glucosidase andα-amylase.In addition,the fluorescent AGEs and the CML/CEL were negatively correlated with the antioxidant activities,while theα-glucosidase andα-amylase activities were positively correlated with the total phenols and total flavonoids.Moreover,the variety of main flavor compounds increased,including esters,alcohols,phenols and acids.The results of the study support the potential use of screened LAB strains to inhibit the formation of fluorescent AGEs,CML and CEL on fermented products and in the food processing industry,without associated risks to consumers. 展开更多

Fluorescent mesoporous silica nanoparticles functionalized with carboxyl group(Znq-CMSCOOH) were successfully synthesized by in situ formation route of 8-hydroxyquinolinate zinc complexes in channels of mesoporous silica nanoparticles and post-grafting of carboxyl group on the surface. Moreover,the particle size and structural properties of Znq-CMS-COOH were characterized by transmission electron microscopy(TEM),field emission scanning electron microscopy(FE-SEM),dynamic light scattering(DLS),Fourier transform infrared spectroscopy(FT-IR),UV-vis spectrometer, fluorescence spectrometer and nitrogen adsorption-desorption measurements. The obtained results suggest that the Znq-CMS-COOH presents the uniform spherical shape with the mean diameter of about 85 nm and the obvious wormhole arrangement mesoporous. In addition, the Znq-CMS-COOH possesses green fluorescence with the emission peaks at 495 nm. So the Znq-CMS-COOH, which is beneficial to further modification and tracing, might be a great potential carrier for applying in drug delivery system in the future. 展开更多

Theabrownins(TBs)are the characteristic functional and quality components of dark teas such as Pu’er tea and Chin-brick tea.TBs are a class of water-soluble brown polymers with multi-molecular weight distribution produced by the oxidative polymerisation of tea polyphenols during the fermentation process of dark tea,both enzymatically and non-enzymatically.TBs have been extracted and purified from dark tea all the time,but the obtained TBs contain heterogeneous components such as polysaccharides and caffeine in the bound state,which are difficult to remove.The isolation and purification process was tedious and required the use of organic solvents,which made it difficult to industrialise TBs.In this study,epigallocatechin(EGC),epigallocatechin gallate(EGCG),epigallocatechin gallate(ECG),EGC/EGCG(mass ratio 1:1),EGCG/ECG(mass ratio 1:1),EGC/ECG(mass ratio 1:1)and EGC/EGCG/ECG(mass ratio 1:1:1)as substrates and catalyzed by polyphenol oxidase(PPO)and peroxidase(POD)in turn to produce TBs,named TBs-dE-1,TBs-dE-2,TBs-dE-3,TBs-dE-4,TBs-dE-5,TBs-dE-6 and TBs-dE-7.The physicochemical properties and the antibacterial activity and mechanism of TBs-dE-1–7 were investigated.Sensory and colour difference measurements showed that all seven tea browning samples showed varying degrees of brownish hue.Zeta potential in aqueous solutions at pH 3.0–9.0 indicated that TBs-dE-1–7 was negatively charged and the potential increased with increasing pH.The characteristic absorption peaks of TBs-dE-1–7 were observed at 208 and 274 nm by UV-visible(UV-vis)scanning spectroscopy.Fourier transform infrared(FT-IR)spectra indicated that they were phenolic compounds.TBs-dE-1–7 showed significant inhibition of Escherichia coli DH5α(E.coli DH5α).TBs-dE-3 showed the strongest inhibitory effect with minimum inhibitory concentration(MIC)of 1.25 mg mL–1 and MBC of 10 mg mL–1,followed by TBs-dE-5 and TBs-dE-6.These three TBs-dEs were selected to further investigate their inhibition mechanism.The TBs-dE was found to damage the extracellular membrane of E.coli DH5α,causing leakage of contents,and increase intracellular reactive oxygen content,resulting in abnormal cell metabolism due to oxidative stress.The results of the study provide a theoretical basis for the industrial preparation and product development of TBs. 展开更多

Seed watermelon kernel is a typical complex food with high fat and protein contents.During storage and processing,it is often affected by various factors to undergo interactions between components,which lead to its quality change.In this experiment,seed watermelon kernels were used as research objects,and the effects of 2-Azobis(2-amidinopropane)dihydrochloride(AAPH)on seed watermelon kernel protein isolates(WMP)were investigated.The structure and digestion characteristics of WMP after oxidation were studied.The results showed that with the increase of AAPH concentration(0.05−5 mol/L),WMP showed obvious aggregation,and its solubility decreased from 6.76 mg/mL to 9.59 mg/mL.The free sulfhydryl content of WMP was 18.24 mmol/g decreased to 11.25 mmol/g,α-helix decreased andβ-sheet decreased in secondary structure,and its disulfide bond increased by 43.06 mmol/g from 39.57 mmol/g,enthalpy(H)and denaturation temperature increased(Td)(P<0.05).By mass spectrometry results of simulated gastric digestion products,it was found that oxidation adversely affected the digestion characteristics of WMP.It can be seen that the lipid oxidation product APPH of seed watermelon kernel can significantly affect the structure and function of the protein extracted from the seed kernel. 展开更多

Immune checkpoint inhibitors(ICIs)therapy targeting programmed cell death ligand 1(PD-L1)and programmed death protein 1(PD-1)had exhibited significant clinical benefits for cancer treatment such as triple negative breast cancer(TNBC).However,the relatively low anti-tumor immune response rate and ICIs drug resistance highlight the necessity of developing ICIs combination therapy strategies to improve the anti-tumor effect of immunotherapy.Herein,the immunomodulator epigallocatechin gallate palmitate(PEGCG)and the immunoadjuvant metformin(MET)self-assembled into tumor-targeted micelles via hydrogen bond and electrostatic interaction,which encapsulated the therapeutic agents doxorubicin(DOX)-loaded PEGCG-MET micelles(PMD)and combined with ICIs(anti-PD-1 antibody)as therapeutic strategy to reduce the endogenous expression of PD-L1 and improve the tumor immunosuppressive microenvironment.The results presented that PMD integrated chemotherapy and immunotherapy to enhance antitumor efficacy in vitro and in vivo,compared with DOX or anti-PD-1 antibody for the therapy of TNBC.PMD micelles might be a potential candidate,which could remedy the shortcomings of antibody-based ICIs and provide synergistic effect to enhance the antitumor effects of ICIs in tumor therapy. 展开更多

Although mixed lineage kinase domain-like protein(MLKL)is widely recognized as a critical effector in the necroptotic signaling pathway,MLKL plays broader regulatory roles beyond programmed necroptosis.Notably,Xuan Yuan et al demonstrated that CPD4,an ATP-binding pocket inhibitor of MLKL,significantly reduces liver inflammation and improves liver function by inhibiting NF-κB signaling,suggesting its use as a potential therapeutic candidate for alcoholic liver disease.However,the pharmacokinetic properties and long-term toxicity of CPD4 require further evaluation.Moreover,a single therapeutic strategy targeting MLKL may not be sufficient.Future studies should focus on the precise regulation of MLKL and develop combination therapies to achieve dual intervention of inflammatory and cell death pathways.This paper provides an important theoretical foundation for translational research on MLKL-targeted therapy.However,its clinical translation requires overcoming existing limitations and further elucidating the regulatory network of MLKL in complex microenvironments. 展开更多

Bladder cancer(BLCA)is a highly invasive malignancy with limited targeted therapies.Lu et al reveal the oncogenic role of HOXC6 in BLCA by showing its elevated mRNA and protein levels in cancerous tissues.Silencing HOXC6 sig-nificantly inhibits BLCA cell proliferation,migration and invasion,induces apo-ptosis and arrests the cell cycle at G0/G1.In addition,HOXC6 also regulates pa-thways related to chemical carcinogenesis and reactive oxygen species,with a strong association with the target gene TIMELESS,supported by binding signals in its promoter region.Here,we discuss the role of HOXC6 as a potential bio-marker and therapeutic target,contributing to a deeper understanding of the HOXC6-TIMELESS axis and its implications for advancing BLCA research and therapy. 展开更多
