Abstract:

Transgenic gene regulatory techniques play a critical role in biomedical fields since they are essential for researchers to study the molecular mechanisms of development and diseases. The currently prevalent transgenic techniques include specific gene mutation, transgenic RNAi and targeting activation, etc. Specifically, various gene regulatory tools have been developed to temporarily and spatially modulate genes in Drosophila melanogaster, which is a typical model organism with evolutionally conserved genome and without ethical issues in scientific research. Here, we introduce several gene regulatory techniques commonly used in Drosophila, including the principle, procedure, toolbox and related transgenic resource of CRISPR/Cas9-triggered heritable gene mutation system, next-generation transgenic RNAi and CRISPR/dCas9-based transcriptional activation (flySAM) approach. We wish to take this opportunity to raise the awareness of the importance of transgenic gene regulatory techniques development and related resource construction and thus to promote biomedical research progression.
