Along with the presence of dysfunctional Notch receptors in leukemia, the ligand Jagged-2 was found to become substantially overexpressed in several myeloma.51 In addition to hematologic malignancies, aberrant Notch signaling has been identified in solid tumors;NICD entersActivation of Notch target genes c-Myc p21 Cyclin D1 Bcl-MAML CSL HAT SKIPNICDcell cycle progression inhibition of apoptosis cell fateCoactivatorHES/HEY familyNucleusCIR SMRT SHARP HDAC SKIP CSLCorepressorFigure 3 Notch-mediated nuclear transcription.
