From: Histone deacetylase inhibitors exert anti-tumor effects on human adherent and stem-like glioma cells
Effects of 1–5 on human glioma CSCs. LN18 cells were grown under sphere forming conditions for 6 days and then inhibitors were added for 24 h. a Representative pictures of LN18-derived spheres show sphere disintegration after exposure to 1–5. b At the end of the experiments, spheres were collected by centrifugation and total protein extracts were prepared. Representative immunoblots show western blot analysis of PARP-1 cleavage, γ-H2AX, p21, and AcH4 levels in glioma spheres after 24 h exposure to 5 μM 1–3, 5, and 1 μM 4. c Densitometry analysis of western blot of PARP-1 cleavage, γ-H2AX, p21, and AcH4 levels in glioma spheres after 24 h exposure to 5 μM 1–3, 5, and 1 μM 4 (n = 2)
