Then, the immunocytochemical staining of human cancer SH-SY5Y cells for neuronal markers such as neurofilaments (NF) was performed after 6 days of treatment in the presence of EO1, EO2, and EO4 at a dose of 50 μg/mL to evidence potential effects of extracts in altering the NF structural organization. This evidence concerns the gene NFASC and cancer.
