Abstract
In order to unfold the function of genes, solely performing mRNA over-expression is not enough nowadays. Traditional protein expression experiments, such as Western blotting and immunohistochemical staining, could only provide researchers the changes of expression levels and/or location of their targets. To make a more strong and convincing statement about gene function, it is necessary to perform both “gain-of-function” and “loss-of-function” studies. Both assays can be performed easily by transfecting DNA plasmid and siRNA in cell culture system; while in zebrafish, mRNA and morpholino (MO) microinjection can serve similar purposes. It is common for the zebrafish community to carry out microinjection experiments to explore a gene function. Instead of making a single knockdown/over-expression of a gene, we foresee that more and more large-scale screens on certain protein families will be performed in the future. Here, based on our previous experience in zebrafish “loss-of-function” screening on deubiquitylating enzymes, we describe a general work flow, from morpholino designation, in situ hybridization, to data analysis, as a reference for researchers who may be interested in a similar screen.
