Like
ankyrins, tankyrase contains 24
ankyrin repeats in a domain responsible
for its interaction with TRF1.
Their collaborators — Paul Jenkins, Ph.D., and Vann Bennett, M.D., Ph.D., then at Duke University Medical Center — had tried creating a mouse mutant completely lacking the
ankyrin - G protein, but the mice didn't survive because
ankyrin - G seems to be required
for nervous system development.
In baseline tests, the high - energy
ankyrin - G mice usually swam longer, only floating
for about 10 seconds of the 200 second test compared to the normal mice that floated about 50 seconds, but after several sessions with the bully mice, the
ankyrin - G mice were quick to give up and float, remaining still
for well over 100 seconds on average.
The research group hopes to use its
ankyrin - G mice to better understand the biology of bipolar disorder, to help clarify how lithium works to treat bipolar disorder, and to test new treatments
for bipolar disorder.
To see if the mutant mice developed depressive - like traits under those conditions, the researchers stressed the
ankyrin - G mice by placing them with a bigger, «bully» mouse
for daily sessions over two weeks.
Specifically, the mice lacked the protein
ankyrin - G, in particular neurons in the brain, a defect that appears to make the animals both hyperactive and less fearful, a behavioral profile suggestive of a mania - like state
for a mouse.
To see what was happening in the brains of these
ankyrin - G mutant mice, the researchers analyzed the cell components in inhibitory synapses connecting with pyramidal neurons, finding that two proteins known as GAT1 and GAD67 — responsible
for making the neurochemical GABA that dials back nerve impulses — were at much lower levels in the synapses on pyramidal neurons in
ankyrin - G mutant mice than in normal mice.
There are also many other differences in the number or coding sequences of
ankyrin repeat genes between wMel strain genomes and wAu [21], [49](see also [15] and [48]
for sequence of wMelCS).
