Figure 2. FUdR upregulates transcriptional expression of the heat shock regulated chaperone hsp16.2 after heat stress. A, B, Fluorescent photomicrographs of animals expressing the transcriptional reporter, phsp16.2::GFP, after heat stress in the absence or presence of FUdR (100 μg/ml). Worms were heat stressed for 1 hour at 35°C and GFP expression was analyzed approximately 5 hours later. C, Quantification of GFP expression from A, B. FUdR-treatment significantly increases GFP levels compared to untreated control animals. (**=p<0.0001, Student's t-test)
