This study investigates the expression pattern and functional significance of EF-hand domain-containing protein 2 (EFHD2) in hepatocellular carcinoma (HCC), with particular focus on its regulatory effects on tumor proliferation, migration, and invasion. Cellular experimental study was completed from June 2024 to January 2025 in the Basic Laboratory of the General Hospital of Southern Theater Command. TCGA database to determine EFHD2 expression and its clinicopathological correlations. GSCA database to assess methylation patterns and immune infiltration. Model of transient overexpression and knockdown of EFHD2 was constructed in hepatocellular carcinoma cells Hep3B, then RT-qPCR and Western blot were applied to verify the transfection efficiency. CCK-8 and colony formation assays for proliferation assessment, Transwell chambers for migration/invasion quantification. Protein-protein interaction networks were constructed via STRING, followed by GO/KEGG enrichment analysis. Statistical analysis was performed using the two independent samples t-test. The results showed that EFHD2 demonstrated significant upregulation in HCC tissues versus normal controls ( P<0.05). Elevated EFHD2 expression correlated with advanced clinical stage ( P<0.05) and poor differentiation ( P<0.05). In the CCK-8 assay, the EFHD2 overexpression group demonstrated significantly higher cell viability than the control group, as evidenced by 450 nm relative absorbance values on Day 1 (0.529±0.019 vs. 0.515±0.016, F=0.041, P=0.320), Day 2 (1.356±0.019 vs. 1.094±0.042, F=3.833, P<0.001), Day 3 (2.817±0.049 vs. 2.143±0.124, F=3.833, P<0.001), and Day 4 (3.848±0.015 vs. 3.430±0.021, F=0.469, P<0.001). The EFHD2 knockdown group showed reduced cell viability compared to controls: Day 1 (0.541±0.020 vs. 0.552±0.015, F=0.098, P=0.423), Day 2 (1.154±0.009 vs. 1.326±0.029, F=2.485, P<0.001), Day 3 (2.453±0.041 vs. 2.653±0.031, F=0.479, P<0.001), and Day 4 (3.685±0.038 vs. 3.836±0.021, F=6.804, P<0.001). In colony formation assays, the overexpression group displayed a significant increase in colony numbers (254.667±23.861 vs. 186.000±16.703, F=0.865, P=0.015), whereas the knockdown group exhibited decreased colony formation (229.000±24.637 vs. 306.667±36.501, F=0.988, P=0.038). In Transwell assays, the EFHD2 overexpression group revealed enhanced migratory capacity [ (605.000±72.670) cells vs. (472.667±28.095) cells, F=2.462, P=0.042] and invasive potential [(767.333±21.221) cells vs. (414.333±16.623) cells, F=0.331, P<0.001]. The knockdown group showed attenuated migration [(311.000±71.084) cells vs. (479.667±50.846) cells, F=0.718, P=0.029] and invasion [(247.667±48.263) cells vs. (345.667±32.130) cells, F=0.727, P=0.043] compared to controls. The network of EFHD2-interacting proteins was further constructed by the STRING database, and the GO and KEGG analysis were used to perform bioinformatics analysis reveal that EFHD2 is mainly involved in actin cytoskeleton regulation. In conclusion, EFHD2 is highly expressed in HCC and is involved in the process of proliferation, migration and invasion of HCC.

Food safety problems caused by foodborne pathogenic bacteria pose a serious threat to public health,creating an urgent need to develop testing methods and techniques with excellent performance and are simple to use and of affordable cost.Traditional testing methods,such as isolation and culture,morphological observation,biochemical identification,and serological tests,have many limitations,including complex procedures,reliance on specialized technical equipment and personnel,and long turnaround time,rendering them inadequate for meeting current and future testing demands.Therefore,it is particularly important to develop simple,rapid,and highly sensitive methods for analyzing pathogenic bacteria.The fusion of nucleic acid aptamers and nanozymes brings new ideas for the rapid testing of pathogenic bacteria.On one hand,aptamers offer specific recognition capability for target bacteria and can be combined with various nucleic acid signal amplification techniques.On the other hand,the enzyme-like catalytic activity and signal amplification effect of many nanomaterials provide a basis for highly sensitive testing.This review highlights the application potential of nanozyme?aptamer coupling systems in the field of microbial analysis by briefly summarizing the latest research progress in the use of nanozymes combined with aptamers for the detection of foodborne pathogenic bacteria.First of all,two main approaches to conjugating nanozymes with aptamers are introduced.Then,the testing mechanisms and typical applications of nanozyme?aptamer coupling systems for foodborne pathogenic bacteria are discussed.Finally,future development trends and existing challenges are disucssed from four perspectives,including specificity,high sensitivity,high throughput,and intelligent detection.This review aims to provide a useful reference for the fusion of nanozymes and aptamers and for the development of on-site rapid testing techniques for foodborne pathogens,and to encourage broader academic interest to further advance this promising research field.

To explore the interaction between ASFV capsid protein M1249L and host from the host cellular perspective,M1249L was selected for constructing the bait plasmid(pGBKT7-M1249L)to screen the bone marrow-derived macrophages(BMDMs)cDNA library.After again co-transform and sequence alignment,20 candidate interacting host proteins were screened,such as IL-1β,CTSB and DNAJA3.And then,co-immunoprecipitation assay was performed to verify the interaction be-tween M1249L and host proteins.GO ontology(GO)and KEGG pathway enrichment analyses re-vealed that biological regulation,cellular communication and response to stimulus and others were enriched in biological processes.And these host proteins could share some pathways,including toll-like receptor signaling pathway and Nod-like receptor signaling pathway.Therefore,the results provides the theoretical basis for further research on the mechanism of ASFV M1249L in viral in-fection and immune regulation.

Purpose: Central nervous system (CNS) relapse is associated with poor survival, and remains an unmet challenge in patients with diffuse large B-cell lymphoma (DLBCL). Identifying patients at high risk of CNS relapse and offering prophylactic treatment could improve patient prognosis. Methods: Here, we studied 234 patients with DLBCL using open patient-level clinical and sequencing data to explore risk factors for CNS relapse. Patients were divided into Cohort A (CNS involvement at baseline), Cohort B (CNS recurrence), and Cohort C (patients without secondary CNS involvement and with a follow-up interval > 3 years). We investigated the risk factors for CNS relapse in Cohorts B + C. Results: Genetic alterations with statistical significance, determined by univariate analysis, and an incidence rate ≥ 5%, together with clinical factors, correlated with CNS relapse risk in a multivariate analysis. Multivariate logistic regression analysis revealed that concomitant MYD88 L265P and CDKN2A loss (p = 0.012), TET2 mutation (p = 0.037), ARID1A mutation (p = 0.010), and INO80 (p = 0.002) were independently correlated with a high risk of CNS relapse after adjusting for the IPI risk groups, B symptom and cell of origin (COO). The classifier that integrated genomic risk factors was superior in predicting CNS relapse (area under the receiver operating characteristic curve [AUROC]: 0.91) compared with the IPI (AUROC: 0.77, p < 0.001) or IPI in combination with COO classifiers (AUROC: 0.81, p = 0.013). Conclusion This study identified several genomic alterations as risk factors for CNS relapse.

Hepatic stellate cells (HSCs) represent a significant component of hepatocellular carcinoma (HCC) microenvironments which play a critical role in tumor progression and drug resistance. Tumor-on-a-chip technology has provided a powerful in vitro platform to investigate the crosstalk between activated HSCs and HCC cells by mimicking physiological architecture with precise spatiotemporal control. Here we developed a tri-cell culture microfluidic chip to evaluate the impact of HSCs on HCC progression. On-chip analysis revealed activated HSCs contributed to endothelial invasion, HCC drug resistance and natural killer (NK) cell exhaustion. Cytokine array and RNA sequencing analysis were combined to indicate the iron-binding protein LIPOCALIN-2 (LCN-2) as a key factor in remodeling tumor microenvironments in the HCC-on-a-chip. LCN-2 targeted therapy demonstrated robust anti-tumor effects both in vitro 3D biomimetic chip and in vivo mouse model, including angiogenesis inhibition, sorafenib sensitivity promotion and NK-cell cytotoxicity enhancement. Taken together, the microfluidic platform exhibited obvious advantages in mimicking functional characteristics of tumor microenvironments and developing targeted therapies.
