Cytarabine 65-85 CD33 molecule Homo sapiens 5-9 15676214-5 2005 RESULTS: CD33 ligation induced a significant increase in ara-C- or IDA- but not VP-16-or Bryostatin-mediated inhibition of proliferation and colony formation. Cytarabine 57-62 CD33 molecule Homo sapiens 9-13 15676214-8 2005 Combined treatment of AML cells by ara-C or IDA with anti-CD33 mAb resulted in higher levels of SHP-1 phosphorylation. Cytarabine 35-40 CD33 molecule Homo sapiens 58-62 15676214-10 2005 CONCLUSION: These data suggest that combined incubation of leukemia cells with anti-CD33 mAb and ara-C or IDA, but not VP-16 or Bryostatin, independently triggers similar events in the downstream signaling cascade, and therefore leads to additive antiproliferative effects and enhanced cytotoxicity.
