Table 3: Expression of proteins involved in DNA damage signaling, chromatin remodeling and proliferation as measured by immunocytochemistry. Non-induced - ADAS cells grown under control conditions in DMEM, 10% FBS, 1% streptomycin-penicillin and 0.1% gentamycin. Induced - ADAS cells after 24 h culture in neuronal induction medium. Diaminobenzidine (DAB) served as a brown chromagen. All images were obtained at 200X magnification.
