Spatial and temporal control of gene expression in is essential in elucidating gene function. Spatial control is facilitated by the UAS/GAL4 system, and this can be coupled with additional adaptations for precise temporal control and fine tuning of gene expression levels. Here we directly compare the level of pan-neuronal transgene expression governed by nSyb-GAL4 and elav-GAL4, as well as mushroom body-specific expression alongside OK107-GAL4. We also compare the temporal modulation of gene expression in neurons with the auxin-inducible gene expression system (AGES) and temporal and regional gene expression targeting (TARGET) systems.
在阐明基因功能方面,基因表达的时空控制至关重要。UAS/GAL4系统有助于实现空间控制,并且可以与其他适应性措施相结合,以实现精确的时间控制和基因表达水平的微调。在这里,我们直接比较了由nSyb-GAL4和elav-GAL4控制的泛神经元转基因表达水平,以及与OK107-GAL4一起的蘑菇体特异性表达。我们还比较了使用生长素诱导基因表达系统(AGES)和时间与区域基因表达靶向(TARGET)系统时神经元中基因表达的时间调控情况。
