Figure Lengend Snippet: Compound 15 inhibits Wnt/β‐catenin activity luciferase assay in HEK‐293T cells transfected with M50 Super 8x TOPFlash (TOP) or its mutated version M51 Super 8x FOPFlash (FOP) used as negative control. Cells were induced with LiCl (50 mM) and treated with the indicated concentrations of 15 for 24 h. Data are represented as the mean ± SD of three independent experiments, each performed in triplicate. * p < 0.05, ** p < 0.01, *** p < 0.005, ns not significant as determined by analysis of variance (ANOVA).

(B) Western blotting analysis of circATM binding to β-catenin in the circRNA pull-down assay. (C) Western blotting analysis of PARP1 levels in HEK293T cells transfected with vector pLC5-ciR and pLC5-circATM plasmids after β-catenin immunoprecipitation. (D) TOPflash and FOPflash reporter assays were carried out to measure the transcriptional activity of TCF/β-catenin in AGS cells. (E) Wnt/β-catenin targets were detected by RT-qPCR after circATM siRNA transfection of AGS cells. (F) Wnt/β-catenin targets were detected by western blotting after circATM siRNA transfection of AGS cells.

Article Title: Smurf1 promotes gastric cancer progression by regulating Axin2-dependent Wnt signaling pathway

doi: 10.1038/s41598-025-23707-3

Figure Lengend Snippet: Smurf1 promoted Wnt/β-catenin signaling activation. ( A ) Parental and Smurf1-overexpressing AGS cells were transfected with TOPflash and FOPflash reporters and treated with Wnt3a, respectively. Wnt/β-catenin signaling activation was assessed using the TOPflash/FOPflash dual luciferase reporter system. Relative luciferase units (RLU) were calculated to assess β-catenin-triggered transcription. After Smurf1 overexpression in AGS cells, cytoplasmic ( B and D ) and nuclear ( C and D ) β-catenin protein levels were measured using the western blot assay. β-actin and Lamin B1 served as cytoplasmic and nuclear markers, respectively. ( E ) After Smurf1 overexpression in AGS cells, β-catenin nuclear translocation was assessed using IF analysis. Red fluorescence indicated β-catenin, and blue fluorescence indicated the nucleus. The results were shown as the median (1st quartile and 3rd quartile). * p < 0.05, ** p < 0.01.

Article Snippet: After Smurf1 overexpression, AGS cells were co-transfected with TOPflash construct (80 ng, Merck) or FOPflash construct (Merck) and pRL-TK plasmid (8 ng, Promega, WI, USA) using PEI max transfection reagent.
