Uterine leiomyoma (UL) is the most common benign tumor in women of reproductive age. Gene therapy using suicidal genes appears to be a promising approach for UL treatment. One of key factors for success of gene therapy is the right choice of genetic construct carrier. A promising group of non-viral carriers for cell delivery of expression vectors is cationic Cys-flanked peptides which form tight complexes with DNA due to electrostatic interactions and the presence of interpeptide disulfide bonds. The paper reports a comparative study of the physico-chemical, toxic, and transfectional properties of the DNA-peptide complexes obtained by matrix polymerization or oxidative polycondensation of Cys-flanked peptides using the chain growth terminator 2-amino ethanethiol. We have demonstrated the therapeutic effect of the delivery of the pPTK-1 plasmid carrying the herpes simplex virus type 1 (HSV-1) thymidine kinase gene into PANC-1, and HEK-293T cell culture as well as into primary UL cells. It has been shown that the carriers obtained by oxidative polycondensation transform primary UL cells more efficiently than those produced by matrix polymerization. Treatment with ganciclovir resulted in the death of up to 40% of UL cells transfected with the pPTK-1 plasmid. The perspectives of use of the polyR6 carrier produced by oxidative polycondensation as a tool for the development of modular peptide carriers for the purposes of UL gene therapy were discussed.

D007889 Leiomyoma A benign tumor derived from smooth muscle tissue, also known as a fibroid tumor. They rarely occur outside of the UTERUS and the GASTROINTESTINAL TRACT but can occur in the SKIN and SUBCUTANEOUS TISSUE, probably arising from the smooth muscle of small blood vessels in these tissues.

D010455 Peptides Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS. Peptide,Polypeptide,Polypeptides
D005260 Female Females
D005822 Genetic Vectors DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.
