Intratumoral anti-HuD immunotoxin therapy for small cell lung cancer and neuroblastoma.

Ehrlich D, Wang B, Lu W, Dowling P, Yuan R (2014) Intratumoral anti-HuD immunotoxin therapy for small cell lung cancer and neuroblastoma. J Hematol Oncol 7:91. doi: 10.1186/s13045-014-0091-3

Summary: HuD protein is a 40-kDa neuronal RNA-binding protein that is expressed in 100% of small cell lung cancer (SCLC) tumor cells. An anti-HuD monoclonal was biotinylated and combined with Streptavidin-ZAP (Cat. #IT-27); this conjugate was tested both in vitro and in vivo. Anti-HuD-SAP eliminated NCI-H69 and Neuro-2a cells at an EC50 of <0.5 μg/ml. 1 mg/kg of the conjugate injected directly into subcutaneous tumors generated in mice resulted in a temporary lack of tumor growth or regression of the tumor. The results demonstrate the potential of HuD as a therapeutic target for SCLC and neuroblastoma.
