Peptide targeting of adenoviral vectors to augment tumor gene transfer

Targeting adenoviral vectors for enhanced gene therapy of uterine leiomyomas.

STUDY QUESTION Is targeted adenovirus vector, Ad-SSTR-RGD-TK (Adenovirus -human somatostatin receptor subtype 2- arginine, glycine and aspartate-thymidine kinase), given in combination with ganciclovir (GCV) against immortalized human leiomyoma cells (HuLM) a potential therapy for uterine fibroids? SUMMARY ANSWER Ad-SSTR-RGD-TK/GCV, a targeted adenovirus, effectively reduces cell growth in Hu...

Neuronal birthdate-specific gene transfer with adenoviral vectors.

The multilayered structure of the cerebral cortex has been studied in detail. Early-born neurons migrate into the inner layer and late-born neurons migrate into more superficial layers, thus establishing an inside-out gradient. The progenitor cells appear to acquire layer-specific properties at the time of neuronal birth; however, the molecular mechanisms of cell-fate acquisition are still uncl...

9 - Targeted Adenoviral Vectors I: Transductional Targeting

Enhanced gene transfer activity of peptide-targeted gene-delivery vectors.

We have evaluated the capacity of the cell-binding heptapeptide SIGYPLP to enhance transgene expression using non-viral and viral gene delivery vectors. Targeted polyplex based vectors showed good levels of DNA uptake in freshly isolated human umbilical vein endothelial cells (HUVECs) compared to untargeted controls, whilst displaying only modest increases in reporter gene activity. The targete...

Adenoviral Vectors for Hemophilia Gene Therapy

Hemophilia is an inherited blood clotting disorder resulting from deficiency of blood coagulation factors. Current standard of care for hemophilia patients is frequent intravenous infusions of the missing coagulation factor. Gene therapy for hemophilia involves the introduction of a normal copy of the deficient coagulation factor gene thereby potentially offering a definitive cure for the bleed...
