Colorectal cancer(CRC)stands among the top prevalent cancers worldwide and holds a prominent position as a major contributor to cancer-related mortality globally.Absent in melanoma 2(AIM2),a constituent of the interferoninducible hematopoietic interferon-inducible nuclear antigens with 200 amino acid repeats protein family,contributes to both cancer progression and inflammasome activation.Despite this understanding,the precise biological functions and molecular mechanisms governed by AIM2 in CRC remain elusive.Consequently,this study endeavors to assess AIM2’s expression levels,explore its potential antitumor effects,elucidate associated cancer-related processes,and decipher the underlying signaling pathways in CRC.Our findings showed a reduced AIM2 expression in most CRC cell lines.Elevation of AIM2 levels suppressed CRC cell proliferation and migration,altered cell cycle by inhibiting G1/S transition,and induced cell apoptosis.Further research uncovered the participation of P38 mitogen-activated protein kinase(P38MAPK)in AIM2-mediated modulation of CRC cell apoptosis and proliferation.Altogether,our achievements distinctly underscored AIM2’s antitumor role in CRC.AIM2 overexpression inhibited proliferation and migration and induced apoptosis of CRC cells via activating P38MAPK signaling pathway,indicating AIM2 as a prospective and novel therapeutic target for CRC.

Gorham-Stout disease(GSD)is a sporadic chronic disease characterized by progressive bone dissolution,absorption,and disappearance along with lymphatic vessel infiltration in bone-marrow cavities.Although the osteolytic mechanism of GSD has been widely studied,the cause of lymphatic hyperplasia in GSD is rarely investigated.In this study,by comparing the RNA expression profile of osteoclasts(OCs)with that of OC precursors(OCPs)by RNA sequencing,we identified a new factor,semaphorin 3A(Sema3A),which is an osteoprotective factor involved in the lymphatic expansion of GSD.Compared to OCPs,OCs enhanced the growth,migration,and tube formation of lymphatic endothelial cells(LECs),in which the expression of Sema3A is low compared to that in OCPs.In the presence of recombinant Sema3A,the growth,migration,and tube formation of LECs were inhibited,further confirming the inhibitory effect of Sema3A on LECs in vitro.Using an LEC-induced GSD mouse model,the effect of Sema3A was examined by injecting lentivirus-expressing Sema3A into the tibiae in vivo.We found that the overexpression of Sema3A in tibiae suppressed the expansion of LECs and alleviated bone loss,whereas the injection of lentivirus expressing Sema3A short hairpin RNA(shRNA)into the tibiae caused GSD-like phenotypes.Histological staining further demonstrated that OCs decreased and osteocalcin increased after Sema3A lentiviral treatment,compared with the control.Based on the above results,we propose that reduced Sema3A in OCs is one of the mechanisms contributing to the pathogeneses of GSD and that expressing Sema3A represents a new approach for the treatment of GSD.

Due to its tropical origins,rice(Oryza sativa)is susceptible to cold stress,which poses severe threats to production.OsNAC5,a NAC-type transcription factor,participates in the cold stress response of rice,but the detailed mechanisms remain poorly understood.Here,we demonstrate that OsNAC5 positively regulates cold tolerance at germination and in seedlings by directly activating the expression of ABSCISIC ACID INSENSITIVE 5(OsABI5).Haplotype analysis indicated that single nucleotide polymorphisms in a NAC-binding site in the OsABI5 promoter are strongly associated with cold tolerance.OsNAC5 also enhanced OsABI5 stability,thus regulating the expression of cold-responsive(COR)genes,enabling fine-tuned control of OsABI5 action for rapid,precise plant responses to cold stress.DNA affinity purification sequencing coupled with transcriptome deep sequencing identified several OsABI5 target genes involved in COR expression,including DEHYDRATION-RESPONSIVE ELEMENT BINDING FACTOR 1A(OsDREB1A),OsMYB20,and PEROXIDASE 70(OsPRX70).In vivo and in vitro analyses suggested that OsABI5 positively regulates COR gene transcription,with marked COR upregulation in OsNAC5-overexpressing lines and downregulation in osnac5 and/or osabi5 knockout mutants.This study extends our understanding of cold tolerance regulation via OsNAC5 through the OsABI5-CORs transcription module,which may be used to ameliorate cold tolerance in rice via advanced breeding.

Using gas-liquid segmented micromixers to prepare nanoparticles that have a homogeneous particle size, controllable shape, and monodispersity advantages. Although nanoparticle aggregation within a microfluid has been shown to be affected by the shear effect, the shear effect triggering conditions in gasliquid two-phase flow is unclear and the aggregation behavior of nanoparticles under the shear effect is difficult to predict, resulting in uncontrollable physical and chemical properties of nanoparticle aggregates. In this study, a numerical simulation of nanoparticle aggregation in gas-liquid two-phase flow under the shear effect is performed using the CFD-DEM method. Then, the effects of total flow rate,gas-liquid two-phase flow ratio, and particle volume fraction on particle aggregation were analyzed to achieve control of particle aggregation shape and size. Meanwhile, the triggering mechanism of the shear effect and the mechanism of the shear effect on the aggregation of nanoparticles were clarified. The results show that increasing the total flow rate or decreasing the gas-liquid two-phase flow rate ratio can induce the shear effect, which reduces the particle aggregation size and makes the morphology tend to be spherical. Moreover, increasing the particle volume fraction, and total flow rate or decreasing the gas-liquid two-phase flow rate ratio also increases the number of particle collisions and induce interparticle adhesion. Hence, particle adhesion and the shear effect compete with each other and together affect particle aggregation.

Slow growth rate restricts the development and growth of seedlings due to nutrients deficiency or nutrient imbalance.Exponential fertilization can enhance the internal nutrient reserves in seedlings at the nursery-stage and strengthen their resistance to adverse conditions.In this study,nitrogen requirements for producing Hydrangea macrophylla‘Hanatemari’that robust seedlings,nutrient dynamics,biomass and growth,was examined utilizing exponential fertilization.The potted seedlings were fertilized with urea under exponential regime at rates of 0.5,1.5 and 2.0 g nitrogen/plant(EF1,EF2,and EF3),respectively.In addition,an unfertilized group treated with equal volume of deionized water was used as control.The results showed that seedlings under 1.5 g N/plant(EF2)had the highest plant growth index and total biomass.The nutrient concentrations of different organs varied in different fertilization treatments.Based on the results of current study,it is concluded that 1.5 g N/plant(EF2)is suitable exponential fertilization treatment for the culture of hydrangea seedlings.Our treatments results showed that 2.0 g N/plant is not suitable for seedling culturing,because of serious nutrient toxicity.These findings will help to improve seedling quality and strengthen the production of H.macrophylla for plantation.

All animals possess a plethora of innate behaviors that do not require extensive learning and are fundamental for their survival and propagation.With the advent of newly-developed techniques such as viral tracing and optogenetic and chemogenetic tools,recent studies are gradually unraveling neural circuits underlying different innate behaviors.Here,we summarize current development in our understanding of the neural circuits controlling predation,feeding,male-typical mating,and urination,highlighting the role of genetically defined neurons and their connections in sensory triggering,sensory to motor/motivation transformation,motor/motivation encoding during these different behaviors.Along the way,we discuss possible mechanisms underlying binge-eating disorder and the pro-social effects of the neuropeptide oxytocin,elucidating the clinical relevance of studying neural circuits underlying essential innate functions.Finally,we discuss some exciting brain structures recurrently appearing in the regulation of different behaviors,which suggests both divergence and convergence in the neural encoding of specific innate behaviors.Going forward,we emphasize the importance of multi-angle and cross-species dissections in delineating neural circuits that control innate behaviors.

The catalytic oxidation of ethyl acetate(EA)was studied over CuO/CeO_(2) catalysts which were prepared by ball milling with different precursors(copper oxide,cerium acetate,cerium dioxide,copper acetate and cerium hydroxide).The CuO/CeO_(2) catalyst(O-A)prepared with copper oxide and cerium acetate as precursors shows very high catalytic activity that 100%EA conversion is achieved at low temperature of 220℃.It is found that specific surface area(112.8 m^(2)/g),particle size of CuO(3.5 nm)and proportion of oxygen vacancies are prominent on the O-A catalyst.Oxygen vacancies in CeO_(2)support are beneficial to enhancing the adsorption and activation of the oxygen.More finely dispersed CuO particles and oxygen vacancies which are derived from the synergistic interaction of Cu-Ce species play an important role in the catalytic oxidation of EA.
