Figure 2.
Relative transcript expression of three stress response genes in T. castaneum following micro-injection with PAMAM-CNTs and dsRNA. T. castaneum larvae were injected with 50 µg/mL naked PAMAM-CNTs or 50 µg/mL PAMAM-CNT-dsRNAαtub and expression measured at 96 h, along with control (saline), dsRNAαtub and dsRNA GFP. Asterisks represent significant differences between untreated and treated larvae (P < 0.001). The data are presented as means ± SEM of three replicate samples.
