Our findings, therefore, indicate that TTR up-regulation is specific to C9ORF72-related diseases. Moreover, we demonstrated that the changes in RNA levels of TTR are reflected by changes in its protein levels in the cerebellum, plasma, and cerebrospinal fluid (CSF). CONCLUSIONS: Based on our findings, TTR may serve as a biomarker for C9ORF72-related diseases, and additionally, could help to unravel biomarker patterns in sporadic diseases. Furthermore, our identification of TTR, which has neuroprotective effects, might also point towards compensatory mechanisms that influence the presentation and/or progression of C9ORF72-related diseases, and that could uncover targets for new therapeutic approaches.Disclosure: Dr. Van Blitterswijk has nothing to disclose.
