Abstract
Currently there are no effective treatments or cures for the debilitating and deadly neurodegenerative
disease Alzheimer's disease (AD), and therefore there is a need for novel target identification that will lead to
effective therapies for this disease. There is strong evidence that overexpression of RCAN1.1 causes AD
progression through hyperphosphorylation of the tau protein which causes development of neurofibrillary
tangles, eventually leading to neuronal loss via apoptosis. For this reason, RCAN1.1 provides a novel target
for silencing therapeutics. On the contrary, expression of RCAN 1.4 has shown a protective effect for neurons
and an overall improvement in the clinical symptoms associated with AD. Therefore a novel tool is needed
that can specifically target RCAN1.1 mRNA while preserving expression of RCAN 1.4.
CRISPR-C2c2 is a novel RNA-guided RNA-targeting system capable of targeting specific RNAs via a
programmable crRNA guide. The CRISPR-C2c2 system is the tool that can provide the mechanism for
specific targeting of RCAN1.1 mRNA therefore potentially providing vital treatment for Alzheimer's disease.
