Experimental details: Immunofluorescence analysis of ROCK2 was performed using 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with ROCK2 Rabbit Polyclonal Antibody (Product # PA5-78290) at 5 µg/mL in 0.1% BSA, incubated at 4 degree Celsius overnight and then with Goat anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32731) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

Experimental details: The expression of lamin A affects YAP and ROCK2 activity and stimulates neural differentiation in EWS cells. a Lamin A-GFP (green) and YAP (red) localization in Empty-GFP clone (pEV #2) and lamin A-GFP #84 (#84). DNA was counterstained with DAPI (DAPI). Merge of fluorescence signals are shown (MERGE). Graphs indicate the fluorescence intensity profile along the white arrows. Representative graphs of at least 30 nuclei analyzed for each sample were shown; magnification 100x, scale bar 10 mum; b Western blotting analysis of YAP, p(Ser127) YAP and MYC protein expression in Empty-GFP clone (pEV #2) and lamin A-GFP #84 (#84). GAPDH was used as loading control. Densitometric analysis is shown as mean values +- SD of three different experiments. Asterisks indicate statistically significant differences with respect to Empty-GFP clone; two-tailed unpaired Student's t-test, * p < 0.05; c Western blotting analyses of lamin A/C and ROCK2 protein expression in Empty-GFP clone (pEV #2), lamin A-GFP #30-40 (#30-40) and lamin A-GFP #84 (#84). GAPDH was used as loading control. Densitometric analysis is shown as mean values +- SD of three different experiments. Asterisks indicate statistically significant differences with respect to Empty-GFP clone; one-way ANOVA test, * p < 0.05, *** p < 0.001; d Western blotting analysis of lamin A/C and ROCK2 protein expression in siRNA scramble cells (SCR) and siLMNA A-673 ( siLMNA ). GAPDH was used as loading control. Densitometric analysis is shown as m
