    6351   Transcription DNA Templated  The Cellular Synthesis of RNA On a Template of Dna. 
    6355   Regulation of Transcription DNA Templated  Any Process That Modulates the Frequency Rate or Extent of Cellular DNA Templated Transcription. 
    6417   Regulation of Translation  Any Process That Modulates the Frequency Rate or Extent of the Chemical Reactions and Pathways Resulting in the Formation of Proteins by the Translation of Mrna. 
    7173   Epidermal Growth Factor Receptor Signaling Pathway  A Series of Molecular Signals Initiated by Binding of a Ligand to the Tyrosine Kinase Receptor Egfr (erbb1) On the Surface of a Cell. the Pathway Ends with Regulation of a Downstream Cellular Process E.g. Transcription. 
    7219   Notch Signaling Pathway  A Series of Molecular Signals Initiated by the Binding of an Extracellular Ligand to the Receptor Notch On the Surface of a Target Cell and Ending with Regulation of a Downstream Cellular Process E.g. Transcription. 
    8543   Fibroblast Growth Factor Receptor Signaling Pathway  The Series of Molecular Signals Generated As a Consequence of a Fibroblast Growth Factor Receptor Binding to One of Its Physiological Ligands. 
    10467   Gene Expression  The Process in Which a Gene's Sequence Is Converted Into a Mature Gene Product or Products (proteins or Rna). This Includes the Production of an RNA Transcript As Well As Any Processing to Produce a Mature RNA Product or an MRNA (for Protein Coding Genes) and the Translation of That MRNA Into Protein. Some Protein Processing Events May Be Included When They Are Required to Form an Active Form of a Product From an Inactive Precursor Form.
