doi: 10.3892/br.2025.2098
Figure Lengend Snippet: TIF1γ is essential for rabeprazole-modulated ECM. (A) GES-1 and (B) AGS cells were treated with or without rabeprazole for 48 h, and the expression of TIF1γ mRNA was analyzed by reverse transcription-quantitative PCR. Data are shown as the mean ± SD and quantified by one sample t-test for significance against 0 µM. *** P<0.001; n=3. (C) Western blotting was used to detect the protein level of TIF1γ in AGS cells in the absence or presence of rabeprazole for 48 h, and the bands were quantified and analyzed using one sample t-test. Data are displayed as the mean ± SD. **** P<0.0001; n=3. (D) TIF1γ promoter plasmid combined with Renilla plasmid were co-transfected into AGS cell for 24 h, followed by treatment with or without rabeprazole for another 24 h. Relative light units were measured using the dual-luciferase reporter assay system according to the manufacturer's instructions. Data are displayed as the mean ± SD and quantified by two sample t-test for significance against 0 µM. ** P<0.01; n=3. (E) Following transfection with pooled shTIF1γ plasmids overnight, AGS cells were treated with or without rabeprazole for another 48 h, and the bands were quantified and analyzed using one sample t-test. ** P<0.01 and **** P<0.0001; n=3. TIF1γ, transcriptional intermediary factor 1γ; FN, fibronectin; Col1a1, collagen type I alpha 1 chain.
