Figure Lengend Snippet: a) Statistical analysis of VEGF protein expression levels. b) Statistical analysis of mobility in scratch experiments. c) and d) Statistical analysis of lumen number and main branch length in tubule formation experiments. e) to h) Detection of osteoprotegerin (OPG), receptor activator of nuclear factor κB ligand (RANKL), and macrophage colony-stimulating factor (M-CSF) secretion in endothelial cell supernatants by enzyme-linked immunosorbent assay (ELISA). i) Statistical analysis of resorption areas. Data are presented as the mean (SD) (n = 3). Statistical significance was determined by one-way analysis of variance followed by Tukey’s multiple comparison test. *p < 0.05, **p < 0.01, and ***p < 0.001.

doi: 10.1007/s12672-025-01763-5

Figure Lengend Snippet: Immunohistochemistry study of tumor specimens of syngeneic mice. a Representative microscopic images of the specimen of syngeneic mice. HE staining and IHC staining for DHODH and the tumor vascular endothelial markers integrin αv, VEGFR2, and CD31 of the tumors from the control (DMSO vehicle control) and LEF-treated (LEF-treated group) groups. Ten fields of view were taken for each specimen, and images of representative fields of view (sample number 4, 5 as control and 8, 9 as test in Fig. ) are shown on the left at low magnification and right at high magnification of the areas highlighted in white rectangle. Black bars in all panels indicated 500 µm. ( b ) Quantitative analysis of IHC positivity rates was conducted by calculating the ratio of the stained area of each marker, DHODH and vascular endothelial cells, to the horizontal projected area of the sections. This analysis was performed using BZ-X Analyzer software (BZ-H4A, Keyence Corporation, Osaka, Japan), with five sections randomly selected for each marker. Statistical analysis was performed using Student’s t-test. Values are expressed as means ± SEM of five sections (* p < 0.05)
