The effects of curcumin on molecular pathways. a Expression of p-jun, jun, p-p38, p38, p-ERK and ERK were assessed by western blot analysis in non-treated (NT) GSCs and 8 h after 25 μM of curcumin. b Expression of p-STAT3 (Tyr705), p-STAT3 (Ser727) and STAT3 was assessed by western blot analysis in non-treated GSCs (NT) GSCs and 8 h after 25 μM of curcumin. c Expression of the anti-apoptosis proteins Survivin, IAP1 and IAP2 were assessed in non-treated GSCs and 24 h after 25 μM of curcumin. Alpha-tubulin was used as a loading control for experiments a–c
