“In A431 cells, vesnarinone induced tyrosine phosphorylation of the overexpressed epidermal growth factor receptors (EGFR) as well as other unidentified proteins, increased the synthesis of cytokeratins, and caused amplification of the intermediate filament networks and cell flattening.”
“This suggests that vesnarinone indirectly activates tyrosine phosphorylation of membrane proteins related to cell adhesion, which influences a signaling pathway linked to the stress fiber assembly in certain cell lines.”
