deprivation and improved the compound
action potential area recovery during
post-oxygen glucose deprivation.
To investigate whether inhibition of
CDK5 and AKT promoted axon function
in optic nerves of 12-month-old mice,
the authors administered roscovitine
or MK-2206, inhibitors of AKT, at
pre-, during, and post-oxygen glucose
deprivation. They observed that roscovitine
given prior to oxygen glucose deprivation
improved compound action potential area,
whereas MK-2206 treatment preserved
compound action potential area during
oxygen glucose deprivation and promoted
axonal recovery following oxygen glucose
deprivation. These observations indicate
that CK2 inhibition improves axon function
recovery following an ischemic episode,
and CDK5 and AKT are effector molecules
that mediate these protective effects.
CONCLUSION
In the study by Bastian and colleagues,
they investigated the use of kinase

inhibitors to treat ischemic strokerelated neuronal injuries. Using aged
mice, which is an appropriate model for
conducting stroke research, they observed
post-ischemic protection following
administration of their therapeutic. As the
authors note, this therapeutic may result
in successful translation into clinical trials.
For nearly 90 years, JAX-a pioneer
in mouse model research-has been
empowering the global biomedical
community with a comprehensive and
innovative range of mouse models of
human disease and preclinical research
services. For researchers, utilizing the
most appropriate model platform can
be the difference between reaching a
milestone and starting a study from the
beginning-with a new target. JAX is
committed to providing access to mouse
models, such as aged C57BL/6J, to
advance scientific discovery.
