    Amyloid-beta (Abeta) peptides, widely presumed to cause Alzheimer's disease, increased mouse neuronal expression of collagen VI through a mechanism involving transforming growth factor signaling. Reduction of collagen VI augmented Abeta neurotoxicity, whereas treatment of neurons with soluble collagen VI blocked the association of Abeta oligomers with neurons, enhanced Abeta aggregation and prevented neurotoxicity. These results identify collagen VI as an important component of the neuronal injury response and demonstrate its neuroprotective potential.

    All links from this record

    • Related Articles

      Calculated set of PubMed citations closely related to the selected article(s) retrieved using a word weight algorithm. Related articles are displayed in ranked order from most to least relevant, with the “linked from” citation displayed first.

    • GENSAT

      Gene Expression Nervous System Atlas (GENSAT) records that cite the current articles. References on GENSAT records are provided by GENSAT investigators, and also include references on the corresponding NCBI Gene record.

    • Gene

      Gene records that cite the current articles. Citations in Gene are added manually by NCBI or imported from outside public resources.

    • Gene (GeneRIF)

      Gene records that have the current articles as Reference into Function citations (GeneRIFs). NLM staff reviewing the literature while indexing MEDLINE add GeneRIFs manually.

    • HomoloGene

      HomoloGene clusters of homologous genes and sequences that cite the current articles. These are references on the Gene and sequence records in the HomoloGene entry.

    • Nucleotide

      Primary database (GenBank) nucleotide records reported in the current articles as well as Reference Sequences (RefSeqs) that include the articles as references.

    • Nucleotide (RefSeq)

      NCBI nucleotide Reference Sequences (RefSeqs) that are cited in the current articles, included in the corresponding Gene Reference into Function, or that include the PubMed articles as references.

    • Nucleotide (Weighted)

      Nucleotide records associated with the current articles through the Gene database. These are the related sequences on the Gene record that are added manually by NCBI.

    • Protein (Weighted)

      Protein records associated with the current articles through related Gene database records. These are the related sequences on the Gene record that are added manually by NCBI.

    • Substance (MeSH Keyword)

      PubChem chemical substance (submitted) records that are classified under the same Medical Subject Headings (MeSH) controlled vocabulary as the current articles.

    • Taxonomy via GenBank

      Taxonomy records associated with the current articles through taxonomic information on related molecular database records (Nucleotide, Protein, Gene, SNP, Structure).

    • UniGene

      UniGene clusters of expressed sequences that are associated with the current articles through references on the clustered sequence records and related Gene records.

    • Protein

      Protein translation features of primary database (GenBank) nucleotide records reported in the current articles as well as Reference Sequences (RefSeqs) that include the articles as references.

    • GEO Profiles
