A Drosophila Model for Screening Antiobesity Agents

Figure 4

Intracellular localization of the GFP signal in the salivary gland. After staining with DAPI, the salivary glands of the third-instar larvae were observed by fluorescence microscopy. There was no detectable GFP signal in control flies (yw), whereas GFP carrying the nuclear localization sequence was detected in the nucleus of transgenic Drosophila (yw; +; bmm promoter-GFP).
