Analysis of Phospho-Ser780-Rb expression levels in U87-MG after 24 h treatment with blank NLCs, free FA, and FA-NLCs. (A) Western blot showing changes in phosphorylation of Rb. β-Tubulin is used as a housekeeping protein; (B) Histogram representing the expression levels of Phospho-Ser780-Rb at the different experimental conditions. Statistical analysis is evaluated through one-way ANOVA test. Results are expressed as the mean ± S.D. of the values obtained from n = 3 independent experiments performed in triplicate. * p = 0.0289 significant differences vs. NLCs, ** p = 0.0089 significant differences vs. FA-NLC.
