Event Ontology Release Notes
=====================
Version: 1.62 (3rd Oct. 2007)

Event Ontology is an ontology that organizes the concepts and terms of pathway objects such as sub-pathways, biological processes and experimental environments appearing in the cellular pathway (e.g. signal transductions, disease pathways, metabolic pathways, etc.) The concepts in the Event Ontology were manually extracted from scientific articles and text books. Each concept has a link to Gene Ontology if possible.

Changes from version 1.61
=====================
[Added terms and definitions]
1. terms related to genetic interaction (e.g., IEV_0003393:synthetic interaction)
2. subpathways related to EPO signaling pathway (e.g., IEV_0003438:Binding of EPO receptor and STAT3)
3. subpathways related to TNFR signaling pathway (e.g., IEV_0003418:Proteasome degradation of c-FLIP)
4. etc.
