Eliminating genes in mice is a standard technique for determining their function; the resultant animals are called knockout mice.

Their report, published May 10
in the journal Nature Communications, suggests that among more than a dozen different lines of
mice developed around the world to mirror autism caused by mutations to the SHANK3
gene, Duke researchers are the first to create a
mouse in which that
gene has been completely
eliminated.
The researchers used
mice in which the telomerase
gene was
eliminated; specifically
in bone marrow cells.
But researchers will have to figure out how to
eliminate the viral DNA used to introduce the
genes, which
in Yamanaka's experiments led to cancers
in 20 percent of
mice grown from blastocysts.
Mitchell and her colleagues
eliminated this possibility when they deleted these nearby regions
in the genome of
mice and found there was no impact on the
gene's ability to be turned on
in embryonic stem cells.
After conducting studies
in both humans and
mice, the researchers said this new schizophrenia risk
gene, called C4, appears to be involved
in eliminating the connections between neurons — a process called «synaptic pruning,» which,
in humans, happens naturally
in the teen years.
They previously showed that knocking out (
eliminating) the
gene Tff1
in mice induces gastric lesions that include low - and high - grade dysplasia and adenocarcinomas.

eliminating one of those
genes, Rab27, led to regeneration of axons
in the optic nerve or spinal cord of
mice.
