genes would not be born alive, the scientists followed up this lead
by making «conditional
knockout mice,» in which Esrp1 and Esrp2 activity was normal early in fetal development, but then was switched off in skin epithelial cells.

by using a systemic mtEF4
gene knockout mouse model, researchers found that mtEF4
knockout damages the oxidative phosphorylation function in germ cells of male mice, thus causing male sterility.

Knockout mice are produced
by a technique called «
gene targeting».
The process used
by NIH to select the mouse lines involved a rigorous scientific review process that evaluated information on the knocked out
gene, the reliability of the method used to produce the
knockout, and whether the mouse line possesses a «reporter»
gene, which enables researchers to analyze the pattern of the
knockout gene's expression in various mouse tissues.
Programmable nucleases, ZFN, TALEN and RGENs enable
gene knockout in cultured cells and organisms
by producing site - specific DNA double - strand breaks, whose repair via error - prone non-homologous end joining (NHEJ) or microhomology - mediated end joining (MMEJ) gives rise to frameshift mutations.
In these mouse lines,
gene knockout can be induced
by Cre recombinase expression while proteins needed for later experiments (cellular tracking for instance) can be controlled with FLP - FRT.

knockouts in candidate disease
genes identified
by association studies, or to broadly overexpress those
genes, are discouraged.
