(A,C,E) Representative fluorescence micrographs of YAP, TAZ, and TGM2 in HTM cells cultured atop ECM hydrogels subjected to vehicle control, dexamethasone (D; 100 nM), simvastatin (S; 10 μM), dexamethasone + simvastatin, and dexamethasone + simvastatin + mevalonate-5-phosphate (M; 500 μM) at 3 d. Arrows indicate YAP/TAZ nuclear localization. Scale bar, 20 μm. (B,D,F) Analysis of YAP/TAZ nuclear/cytoplasmic ratios and TGM2 fluorescence intensity (N = 27-34 images from 3 HTM cell strains with 3 experimental replicates per cell strain). Symbols with different colors represent different cell strains; dotted lines indicate control baselines. The bars and error bars indicate Mean ± SD. Significance was determined by two-way ANOVA using multiple comparisons tests; shared significance indicator letters = non-significant difference (p>0.05), distinct letters = significant difference (p<0.05). (G) Qualitative immunoblot of TGM2 with GAPDH serving as loading control (N = 1 per group [pooled from 3 experimental replicates] from 1 HTM cell strain).
