Dynamics of signaling, cytoskeleton and cell cycle regulation proteins in glioblastoma cells after sub-lethal photodynamic treatment: Antibody microarray study

► Phosphorylation of protein kinases Raf, FAK and Pyk2 and overexpression of PKCγ. ► Down-regulation of actin skeleton-related proteins dystrophin, calponin and vinculin. ► Various changes of microtubule-associated proteins tau, MAP-1B, MAP2 and CNP. ► Down-regulation of cMyc, some cyclins and checkpoint proteins inhibits proliferation. ► Antiapoptotic response with Bcl-xL overexpression and caspase 9 down-regulation.
