Objective To investigate the role and molecular mechanism of exosomal miR-224-5p in colorectal cancer(CRC).Methods The miR-224-5p expression in CRC patient tissues and cell-derived exosomes was measured by laser capture microdissection and qRT-PCR,respectively.Dual-luciferase reporter gene assay was used to determine the target gene of miR-224-5p.The protein expressions of p53 and unc-51 like kinase 2(ULK2)in CRC cells were detected by western blot.Flow cytometry was used to detect cell cycle and apoptosis.Cell proliferation was measured by CCK8 and EdU assay.Results The miR-224-5p expression was upregulated in CRC tissues and increased progressively with the rise of CRC stage.CRC cells secreted extracellular miR-224-5p mainly in an exosome-dependent manner,and then miR-224-5p could be transferred to surrounding tumor cells to regulate cell proliferation in the form of autocrine or paracrine.Moreover,ULK2 was characterized as a direct target of miR-224-5p and was downregulated in CRC tissues.Interestingly,ULK2 inhibited CRC cell proliferation in a p53-dependent manner.Furthermore,exosome-derived miR-224-5p partially reversed the proliferation regulation of ULK2 on CRC cells.Conclusion Our findings demonstrate that exosome-transmitted miR-224-5p promotes p53-dependent cell proliferation by targeting ULK2 in CRC,which may offer promising targets for CRC prevention and therapy.

Social experience has a far-reaching impact on the brain and behavior.In humans,lacking social experience during childhood is associated with a faster decline in later-life cognitive function[l],while social isolation in the elderly is an independent risk factor for dementia[2].The lack of social experience at different stages of life has significant adverse effects on cognitive development and mental health.Studies have largely been focused on the neuronal activity and synaptic plasticity changes after social deprivation.Two recent studies separately reported increased expression of an astrocyte marker,glial fibrillary acidic protein,in socially isolated perinatal or adult mice demonstrating structural changes in astrocytes after social deprivation[3,4].However,it is still unknown whether and how astrocyte function is impacted by social deprivation.

Vaccines have proven effective in protecting populations against COVID-19,including the recombinant COVID-19 vaccine(Sf9 cells),the first approved recombinant protein vaccine in China.In this positive-controlled trial with 85 adult participants(Sf9 cells group:n=44;CoronaVac group:n=41),we evaluated the safety,immunogenicity,and protective effectiveness of a heterologous boost with the Sf9 cells vaccine in adults who had been vaccinated with the inactivated vaccine,and found a post-booster adverse events rate of 20.45%in the Sf9 cells group and 31.71%in the CoronaVac group(p=0.279),within 28 days after booster injection.Neither group reported any severe adverse events.Following the Sf9 cells vaccine booster,the geometric mean titer(GMT)of binding antibodies to the receptor-binding domain of prototype SARS-CoV-2 on day 28 post-booster was significantly higher than that induced by the CoronaVac vaccine booster(100,683.37 vs.9,451.69,plizing antibodies against pseudo SARS-CoV-2 viruses(prototype and diverse variants of concern[VOCs])increased by 22.23–75.93 folds from baseline to day 28 post-booster,while the CoronaVac group showed increases of only 3.29–10.70 folds.Similarly,neutralizing antibodies against live SARS-CoV-2 viruses(prototype and diverse VOCs)increased by 68.18–192.67 folds on day 14 post-booster compared with the baseline level,significantly greater than the CoronaVac group(19.67–37.67 folds).A more robust Th1 cellular response was observed with the Sf9 cells booster on day 14 post-booster(mean IFN-γ+spot-forming cells per 2×105 peripheral blood mononuclear cells:26.66 vs.13.59).Protective effectiveness against symptomatic COVID-19 was approximately twice as high in the Sf9 cells group compared to the CoronaVac group(68.18%vs.36.59%,p=0.004).Our study findings support the high protective effectiveness of heterologous boosting with the recombinant COVID-19 vaccine(Sf9 cells)against symptomatic COVID-19 of diverse SARS-CoV-2 variants of concern,while causing

作者： chen-chen Zhang Sheng Wei li-xian Sun yi-Fang Ouyang Fen Xu Hai-liang Chu Hong-GePan li-Xin chen Xue-Zhang Xiao School of Material Science and Engineering Guilin University of Electronic TechnologyGuilin541004China School of Chemistry and Chemical Engineering Guangxi UniversityNanning530004China Shenzhen Institute of Advanced Technology Chinese Academy of SciencesShenzhen518055GuangdongChina Institute of Science and Technology for New Energy Xi'an Technological UniversityXi'an710021China School of Materials Science and Engineering Zhejiang UniversityHangzhou310058China

Electrocatalytic water splitting coupled with sustainable energies is identified as an environmentally friendly and renewable strategy to generate high-quality hydrogen for the fuel cells.However,the main challenge is to develop high performance,low cost and chemically stable electrocatalysts to decline the energy barriers and enhance the sluggish kinetics of hydrogen evolution reaction(HER).Herein,a three-dimensional hierarchically ordered macroporous Ru-CoP@NC electrocatalyst(3DOM Ru-CoP@NC)derived from ordered macro-microporous metal-organic frameworks has been prepared using the precursor@template and double-solvent methods.The prepared 3DOM Ru-CoP@NC catalyst exhibits an overpotential of 15 mV(j=10 mA·cm^(-2))and a reaction Tafel slope of 38 mV·dec^(-1)in alkaline electrolyte,which are superior to commercial Pt@C catalyst.Additionally,the overpotential and reaction Tafel slope of this catalyst in acidic media are 45 mV and 50 mV·dec^(-1),respectively.The outstanding HER activities of 3DOM Ru-CoP@NC catalysts are ascribed to the 3D highly interconnectedreticular nanospaces that can increase effective reaction active sites.The N dope d carbon framework improves the electronic properties and conductivity.Moreover,the strong interaction of Ru and CoP nanoparticles also boosts the HER process.These results indicate that 3DOM Ru-CoP@NC catalysts with high catalytic activities have a broad application prospect in the future.

Free radicals trigger the closure of open pores in lignin-derived hard carbons toward improved sodium-storage capacity

The chemical activation of various precursors is effective for creating additional closed pores in hard carbons for sodium storage.However,the formation mechanism of closed pores under the influence of pore-forming agents is not well understood.Herein,an effective chemical activation followed by a high-temperature self-healing strategy is employed to generate interconnected closed pores in lignin-derived hard carbon(HCs).By systematic experimental design combined with electron paramagnetic res-onance spectroscopy,it can be found that the content of free radicals in the carbon matrix influences the closure of open pores at high temperatures.Excessively high activation temperature(>700 C)leads to a low free radical concentration,making it difficult to achieve self-healing of open pores at high tempera-tures.By activation at 700°C,a balance between pore making and self-healing is achieved in the final hard carbon.A large number of free radicals triggers rapid growth and aggregation of carbon microcrys-tals,blocking pre-formed open micropores and creating additional interconnected closed pores in as-obtained hard carbons.As a result,the optimized carbon anode(LK-700-1300)delivers a high reversible capacity of 330.8 mA h g^(-1) at 0.03 A g^(-1),which is an increase of 86 mA h g^(-1) compared to the pristine lignin-derived carbon anode(L-700-1300),and exhibits a good rate performance(202.1 mA h g^(-1) at 1 A g^(-1)).This work provides a universal and effective guidance for tuning closed pores of hard carbons from otherprecursors.

ObjectiveTo provide comprehensive evidence for the anti-cancer cachexia effect of Jianpi Decoction(JP)and to explore its mechanism of anti-cancer cachexia.MethodsA mouse model of colon cancer(CT26)-induced cancer cachexia(CC)was used to investigate the anti-CC effect of JP combined with medroxyprogesterone acetate(MPA).Thirty-six mice were equally divided into 6 groups:normal control,CC,MPA(100 mg·kg^(−1)·d^(−1)),MPA+low-dose(20 mg·kg^(−1)·d^(−1))JP(L-JP),MPA+medium-dose(30 mg·kg^(−1)·d^(−1))JP(M-JP),and MPA+high-dose(40 mg·kg^(−1)·d^(−1))JP(H-JP)groups.After successful modeling,the mice were administered by gavage for 11 d.The body weight and tumor volume were measured and recorded every 2 d starting on the 8th day after implantation.The liver,heart,spleen,lung,kidney,tumor and gastrocnemius muscle of mice were collected and weighed.The pathological changes of the tumor was observed,and the cross-sectional area of the gastrocnemius muscle was calculated.The protein expressions of STAT3 and E3 ubiquitinase in the gastrocnemius muscle were measured by Western blot.In addition,an in vitro C2C12 myotube formation model was established to investigate the role of JP in hindering dexamethasone-induced muscle atrophy.In vitro experiments were divided into control,model,and JP serum groups.After 2-d administration,microscopic photographs were taken and myotube diameters were calculated.Western blot was performed to measure the protein expressions of STAT3 and E3 ubiquitinase.ResultsJP combined with MPA restored tumor-induced weight loss(P<0.05,vs.CC)and muscle fiber size(P<0.01,vs.CC).Mechanistically,JP reduced the expression of atrophy-related proteins MuRF1 and MAFbx in tumor-induced muscle atrophy in vivo(P<0.05,vs.CC).In addition,JP reduced the expression of atrophy-related proteins MuRF1 and MAFbx and p-STAT3 phosphorylation(P<0.05 or P<0.01 vs.model group)in C2C12 myotubes treated with dexamethasone in vitro.ConclusionsAdministration of JP combined with MPA restores tumor-induced cachexia conditions.In addition,the
