The combinational therapy with S1Plyase siRNA (siS1PLyase) and recombinant high mobility group box-1 box A peptide (HMGB1A) may have a synergistic effect for the treatment of acute lung injury (ALI). For efficient delivery, the R3V6 peptides were used as a carrier. The ternary complex of siS1PLyase, HMGB1A, and R3V6 was produced by charge interaction. The(More)
Bevacizumab (Avastin) is an angiogenesis inhibitor used as a treatment for various cancers. In this study, the combination therapy of Avastin and glioblastoma-specific thymidine kinase gene [pEpo-NI2-SV-herpes simplex virus thymidine kinase(HSVtk)] was evaluated in a glioblastoma animal model. The R7L10 peptide was used as a gene carrier of(More)
MicroRNA-21 (miR-21) expression in glioblastoma inhibits the expression of pro-apoptotic genes, thereby promoting tumor growth. A previous study showed that the amphiphilic R3V6 peptide is an efficient carrier of the anti-miR-21 antisense oligodeoxynucleotide (antisense-ODN) into cells in vitro. In the current study, in vivo delivery of antisense-ODN using(More)
Solid tumors have hypoxic regions in their cores, due to low blood supply levels. Therefore, hypoxia-specific gene regulation systems have been developed for tumor-specific gene therapy. In this study, the oxygen-dependent degradation (ODD) domain on activating transcription factor-4 (ATF4) was evaluated for post-translational regulation of proteins. The(More)
Combined delivery of chemical drug and therapeutic gene has been introduced as an efficient method for the treatment of cancers such as glioblastoma. In this study, bis-chloroethylnitrosourea (BCNU) and vascular endothelial growth factor (VEGF) small interfering RNA (VEGF-siRNA) were co-delivered into C6 glioblastoma cells using a non-toxic peptide-based(More)
Inhibition of microRNA-21 (miR-21) has been shown to promote apoptosis of cancer cells and to reduce tumor size in glioblastoma. However, efficient carriers for antisense-oligodeoxynucleotide (antisense-ODN) against miR-21 have not yet been developed. In this study, the R3V6 peptide (R3V6) was evaluated as a carrier of antisense-ODN. In a gel retardation(More)
High mobility group box-1 (HMGB-1) is a DNA binding nuclear protein and pro-inflammatory cytokine. The box A domain of HMGB-1 (rHMGB-1A) exerts an anti-inflammatory effect, inhibiting wild-type HMGB-1 (wtHMGB-1). In this study, HMGB-1A was evaluated as an siRNA carrier with anti-inflammatory effects. HMGB-1A was expressed and purified by consecutive nickel(More)
