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.

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

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.

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 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.

NCBI protein 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.

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.

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

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

Gene Expression Omnibus (GEO) Profiles of molecular abundance data. The current articles are references on the Gene record associated with the GEO profile.

Full-text articles in the PubMed Central Database that cite the current articles.

NCBI Bookshelf books that cite the current articles.
