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.

Purpose To explore the value of 5.0T MRI arterial spin labeling and morphological indexes for staging chronic kidney disease(CKD).Materials and Methods Ninety-five patients with CKD in Chongqing University Three Gorges Hospital from January to August 2024 were collected prospectively,all of whom underwent 5.0T MRI routine and arterial spin labeling examination with calculation of renal blood flow(RBF)and morphological evaluation.According to the estimated glomerular filtration rate(eGFR),the patients were categorized into early CKD group[eGFR 60-89 ml/(min?1.73 m2)]and intermediate-late CKD group[eGFR<59 ml/(min?1.73 m2)]and were further divided into stage 1-5.The differences in RBF between early and intermediate-late CKD patients were compared,and the differences in morphological indexes among different stages of CKD were also analyzed.Binary Logistic regression analysis was used to screen for independent influences on early or intermediate-late CKD staging.Receiver operating characteristic curve was used to evaluate the diagnostic efficacy of RBF values and morphological indexes for early CKD.RBF in CKD stages 1-5 were compared,with Bonferroni pairwise comparisons.The correlation between RBF values and both clinical and morphological indexes were also assessed.Results Whether in CKD stage 2 or 5,morphological factors affecting CKD staging were renal parenchymal signal,renal corticomedullary demarcation,renal volume and renal envelope(χ2=53.715,73.368,36.488,56.688,35.630,39.499,28.520,32.632,all P<0.001).In CKD stage 2,the independent influences screened by multivariate binary Logistic regression analysis were renal parenchymal signal(P<0.001)and renal corticomedullary demarcation(P=0.021).Both renal RBF values in early CKD were significantly higher than that in intermediate-late CKD(Z=-5.975,-5.885,both P<0.001).The areas under the curve for diagnosing early CKD using mean RBF of both kidneys,morphological indexes,and the combination of mean RBF with renal morphological indexes were 0.854,0.932 and 0.951,respectively.RBF values for both kidneys showed statistically significant differences among the five CKD stages(left:H=48.738;right:H=48.102,both P<0.001)and between non-adjacent stages(all P<0.05).Both kidneys RBF values showed a positive correlation with renal parenchymal signal and renal corticomedullary demarcation(left:r=0.600,0.503;right:r=0.550,0.504,both P<0.001).Conclusion The integration of arterial spin labeling and morphological assessment on 5.0T MRI enables a noninvasive and precise functional and morphological evaluation of early renal damage in CKD patients,providing a foundation for subsequent clinical CKD staging.
