doi: 10.1186/s12957-026-04308-4

Figure Lengend Snippet: a , b FOXA2 expression profiles in hFOB1.19, MNNG-HOS, 143B, U-2OS and Saos-2 were determined using western blot analysis and qRT-PCR. c FOXA2 expression patterns in OS tissues were exploredusing IHC staining. Scale bar = 50 μm. d The scores for IHC images of OS tissues in T1 ( n = 10) and T2 ( n = 30) stages using anti-FOXA2 antibody were shown. e R2 database analysis of 88 OS cases revealed a correlation between FOXA2 expression and both overall and metastasis-free survival rates. Significance levels were set as follows: ns p > 0.05, * p < 0.05, ** p < 0.01, and *** p < 0.001

Figure Lengend Snippet: a Knockdown efficiency of FOXA2-specific shRNA in MNNG-HOS and 143B cells was determined using western blot. b CCK-8 experiments demonstrated that FOXA2 silencing reduced MNNG-HOS and 143B cell proliferation. c , d Colony formation assays showed that FOXA2 knockdown inhibited OS cell (143B and MNNG-HOS) proliferation. e , f The migration and invasion capabilities of cells were evaluated using Transwell assays. Data were expressed as mean ± SD. Scale bar = 100 μm. Significance levels were set as follows: ns p > 0.05, * p < 0.05, ** p < 0.01, and *** p < 0.001

Figure Lengend Snippet: a Nine common target genes were identified by overlapping the mTOR signaling pathway gene set with FOXA2 target genes predicted by CHIP-ATLAS, ENCODE, GTRD, and hTFtarget databases. b qRT-PCR analysis of EIF3A, EIF4A1, EIF4EBP1, mTOR, PI3KCA, Rheb, TSC1, RPS6KB1, and TSC2 in MNNG-HOS and 143B cells. c JASPAR database predicted binding sites between transcription factor FOXA2 and Rheb promoter. d ChIP assay was conducted to verify the FOXA2-binding site in the Rheb promoter region within 143B and MNNG-HOS cell lines. Controls comprised IgG and input fractions. e Luciferase reporter plasmids with either wild-type or mutant Rheb2 promoters were used for assessment of luciferase activities in 143B and MNNG-HOS. The mutation site is highlighted in red. f 143B and MNNG-HOS cells with FOXA2 knockdown, FOXA2 knockdown combined with Rheb overexpression, and negative controls were used to analyze Rheb, total and phosphorylated mTOR, xCT, and GPX4 at the protein level. Data are presented as mean ± SD. Significance levels were set as follows: ns p > 0.05, * p < 0.05, ** p < 0.01, *** p < 0.001
