a Number of variants (MAF < 3%) in each LSD gene is shown for the IPDGC discovery cohort, including total number of non-synonymous variants and likely damaging variants based on CADD (in parentheses). Of the 54 LSD genes considered, no genic variants in CLN5 or NEU1 passed quality control filters (see “Materials and Methods” section), and no non-synonymous variants were identified in SUMF1.

GPR37

Target

  • Insoluble form of GPR37 has been reported to accumulate in the brains of AR-JP patients [9],
  • mice lacking GPR37 are partially protected against dopaminergic cell death caused by 1-methyl-4-phenyl-1,2,3,6- tetrahydropyridine [12].
  • In SN (other regions?) of sPD (Braak stage 3-6): ↑ GRP37 protein (both overall & N-term cleaved form), ↑ GRP37 mRNA, in sPD

Genetic evidence

Strong

Bm

ecto-GPR37 as a potential PD biomarker

  • ↑ amounts of ecto-GPR37 peptides in the CSF samples from PD patients
  • PROCess
    1. To test if BM is to exist in CSF: immunoprecipitation with antibody → identification of the isolated peptides using LC-MS
    2. Assay development (ELISA, Species-specific) →
    3. measure in mouse CSF →
    4. measure in post-mortem human CSF (control & ↑ PD): small cohort →
    5. measure in post-mortem human CSF (control & ↑ PD): a larger and different cohort
      : good ROC, but no correlation with disease severity
  • No IVC
  • No mechanistic study

Questions

  • target vs bm
  • ratification
  • D-responsible neurodegeneration mechanism

Glossary

EWHV's post-transcriptional regulatory element
Woodchuck Hepatitis Virus
Salk Institute scientists have identified cis-acting RNA elements from the Woodchuck Hepatitis Virus (WHV) that substantially increase the expression of transgenes delivered by retroviral vectors, in particular WHV's post-transcriptional regulatory element (WPRE). Insertion of specific WPRE in the 3′ untranslated region of coding sequences carried by either oncoretroviral or lentiviral vectors substantially increased levels of gene expression in a transgene-, promoter- and vector-independent manner
