Dr. Swapan K. Ray, Department of Pathology, Microbiology, and Immunology, University of South Carolina School of Medicine and his team should positive results in reducing growth of Glioblastomas by knocking down hTERT expression using Neuromics' i-Fect ™ siRNA Transfection Kit.

Results: In vitro and in vivo angiogenesis assays showed inhibition of capillary-like network formation of microvascular endothelial cells and neovascularization under dorsal skin of nude mice, respectively. We observed inhibition of intracerebral tumorigenesis and s.c. solid tumor formation in nude mice after treatment with combination of hTERT siRNA and IFN-γ. Western blotting of solid tumor samples showed significant downregulation of the molecules that regulate cell invasion, angiogenesis, and tumor progression.
Conclusions: Our study showed that the combination of hTERT siRNA and IFN-γ effectively inhibited angiogenesis and tumor progression through the downregulation of molecules involved in these processes. Therefore, the combination of hTERT siRNA and IFN-γ is a promising therapeutic strategy for controlling the growth of human glioblastoma.
