The Pathway Interaction Database, the authoritative collection of signaling pathways that take place in human cells, has just been updated for July. The database is brought to you, free of charge, by the US National Cancer Institute (NCI) and Nature Publishing Group, and is updated each month. To date, there are 51 human pathways and 2,642 molecular interactions curated by NCI—Nature, and 254 human pathways and 3,003 interactions imported from Biocarta. Recently added pathways are a4b1 and a4b7 integrin signalling, and p75(NTR) mediated signalling.
