Figure Lengend Snippet: Yoda1 promotes YAP nuclear translocation through calcium ion influx and inhibits cell apoptosis. (a) Intracellular calcium ion (Ca 2+ ) influx levels in human gingival fibroblasts (HGFs) under various treatment conditions were detected using the Fluo-8 AM fluorescent probe. Representative fluorescence images (green) and quantitative analyses of fluorescence intensity are shown (n = 5 per group), with nuclei counterstained with DAPI (blue). (b) Immunofluorescence staining was used to detect the expression, distribution, and quantitative statistics of the YAP transcription factor (green) and cytoskeleton (F-actin, labeled with phalloidin) in HGF under different treatments (n = 3 per group), with nuclei counterstained with DAPI (blue). (c) Western blot analysis of apoptosis-related proteins Bax and Bcl-2 expression levels in HGFs under different treatments, with grayscale value quantification (n = 3 per group,all proteins levels are normalized to loading control, GAPDH). Quantitative data are presented as mean ± standard deviation (mean ± SD) from at least three independent experiments. Differences between groups were analyzed by one-way ANOVA (* P < 0.05, ** P < 0.01, *** P < 0.001).
Article Snippet: HGFs in the respective experimental groups were treated, and intracellular calcium ions were subsequently detected using Fluo-8 AM (Applygen).
