Gene Suppression Therapies in Hereditary Cerebellar Ataxias: A Systematic Review of Animal Studies

Santos C, Malheiro S, Correia M, Damásio J. Gene Suppression Therapies in Hereditary Cerebellar Ataxias: A Systematic Review of Animal Studies. Cells. 2023; 12(7):1037. https://doi.org/10.3390/cells12071037 

In FRDA, only the suppression efficacy of the electroporation of the clustered regularly interspaced short palindromic repeats associated with Cas9 enzyme system (CRISPR-Cas9) system was tested and confirmed. Conclusion: The literature reviewed suggests that GSTs are well tolerated and effective in suppressing the targeted proteins, improving neuropathological features and the motor phenotype in vivo. Nonetheless, there is no guarantee that these results are free of bias. Moreover, further investigation is still needed to clarify the GST effect on HCAs such as FRDA, SCA6 and SCA2.
