Fig. 2From: Developmental basis for intestinal barrier against the toxicity of graphene oxideEffects of intestine-specific RNAi knockdown of intestine-developmental related genes on distribution and translocation of GO. The pharynx (*) and the intestine (**) were indicated by asterisks. Single arrowhead indicates the spermatheca, and double arrowhead indicates the tail. Acute exposure was performed from L4-larvae for 24 h. GO exposure concentration was 10 mg/L. Bars represent means ± SD. **P < 0.01 vs VP303Back to article page
