Find MND Biomarker

Welcome to FindMNDBiomarker, an integrative database that consolidates the proteomic findings in brain tissue and biofluids (CSF and blood) from patients with motor neuron disease (also known as amyotrophic lateral sclerosis). FindMNDBiomarker is designed for users to quickly assess whether their proteins of interest have been identified in other cohorts and biosamples from patients with MND/ALS.

Purpose: The goal of this search platform is to facilitate the comparison and discovery of proteins that may serve as promising and reproducible biofluid biomarkers of brain-specific changes in MND/ALS and to identify markers that should be further targeted for analyses and validation.

Using this database: Searches can be performed by entering the protein UniProt IDs, names and sample types into the relevant search term box using free text entry. For example, entering ‘NEFL’ will generate a list of all publications in which NEFL was identified to be significantly dysregulated.

A searchable and filterable table is provided with the following columns:

  • Name: Gene name corresponding to the UniProt ID
  • UniProt ID: UniProt accession number
  • Publication: Study Reference
  • Condition: e.g.ALS – Control, ALS Fast – ALS Slow
  • Sample Type: Sample type used (Abbreviations: SMNs, single motor neurons; AH, anterior horn; PH, posterior horn)
  • Regulation: Direction of change (upregulated or downregulated)
  • Cohorts: Cohort size used for each study
  • Average age at onset ± standard deviation/age range: Average age at onset of ALS cohorts with standard deviation or age range (if provided by publication)
  • Average age at collection ± standard deviation/age range: Average age at collection of ALS cohorts with standard deviation or age range (if provided by publication)
  • Average PMI (range) (hours): Average postmortem interval with range (if provided by tissue studies)
