Fig. 3From: Radix Scrophulariae extracts (harpagoside) suppresses hypoxia-induced microglial activation and neurotoxicityEffect of harpagoside on hypoxia-induced inflammatory gene expression (IL-1β, IL-6) of microglial cells. Three hours’ hypoxia stimulates microglial cells IL-1β and IL-6 genes expression, with its maximal effect occurred at 6 h’ culture. The pre-incubation of 10−8 M harpagoside again can inhibit these effects (n = 4). Note: *: p < 0.05Back to article page
