Simulated microgravity inhibits FAK and RhoA activation. (A) Lysates prepared from BL6-10 cells cultured for 3 days at 1 g or µg or µg + CNF1 were subjected to SDS-PAGE analysis. Proteins were transferred onto PVDF membranes and blotted with indicated antibodies. Western blot band signals were quantified by chemiluminescence. Densitometric values were normalized to matching GAPDH controls. Data represent the mean ± SD of three independent experiments. (B) BL6-10 cells exposed for 3 days to 1 g, µg and µg + CNF1 were analyzed for RhoA activity by using the G-LISA RhoA Activation Assay Biochem kit. Data represent the mean ± SD of three independent experiments. **p < 0.05 versus indicated groups. One representative experiment of two is shown.
