A tag cloud built from MESH terms associated with Brca1. This tag cloud was built automatically using the iHOPerator user-script. It is composed of MESH terms extracted from abstracts associated with the gene Brca1 (in mouse). Colour (redness) correlates with the impact factor of the journals where the term occurs. Size correlates with the number of times the term occurs in association with the gene – in this case Brca1.
