Blot analysis of NFATc1 and IRF4 protein expression in nuclear and cytoplasmic fractions of RAW264.7 cells cultured inside the presence of 50 ng/mL RANKL at 0, 1, two and 4 d. Expression levels of B23 and EPS protein have been measured as the loading controls for nuclear and cytoplasmic fractions, respectively.

Expression of IRF4 mRNA (major proper) and protein (decrease suitable). Expression levels of GAPDH mRNA and b-actin protein had been measured because the loading controls.
