The nuclear envelope is a major barrier for nuclear uptake of plasmids and represents one of the most significant unsolved problems of nonviral gene delivery. We have previously shown that the nuclear entry of plasmid DNA is sequence-specific, requiring a 366-bp fragment containing the SV40 origin of replication and early promoter. In this report, we show(More)
Skeletal muscle is established as an ideal tissue for gene delivery to treat systemic diseases. However, the relatively low levels of gene expression obtained from using naturally occurring promoters, including the strong cytomegalovirus (CMV) enhancer/promoter (E/P), have limited the use of muscle as a target tissue. The relatively weak simian virus 40(More)
Growth hormone releasing hormone (GHRH) is known to have multiple anabolic effects and immune-stimulatory effects. Previous studies suggest that treatment with anabolic hormones also has the potential to mitigate the deleterious effects of cancer cachexia in animals. We studied the effects of plasmid-mediated GHRH supplementation on tumor growth and the(More)
INTRODUCTION Eleven hundred eighty-four depressed women were entered into five short-term (8 weeks) studies of gepirone-extended release (ER) vs. placebo for treatment of major depressive disorder (MDD) (134001, 134002, and 134017), or atypical depressive disorder (ADD) (134004 and 134006). The effect of depression on sexual function was examined prior to(More)
Intramuscular (i.m.) injection of plasmids followed by electropermeabilization is an efficient process to deliver genes into skeletal myofibers that permits proteins to be produced and secreted at therapeutically relevant levels. To further improve skeletal muscle as a bioreactor, we identified a formulation that elevates transgene expression in myofibers(More)
Skeletal muscle is an attractive target for gene therapies to treat either local or systemic disorders, as well as for genetic vaccination. An ideal expression system for skeletal muscle would be characterized by high level, extended duration of expression and muscle specificity. Viral promoters, such as the cytomegalovirus (CMV) promoter, produce high(More)
Gene therapy, as a safe and efficacious treatment or prevention of diseases, is one of the next fundamental medical innovations. Direct injection of plasmid into skeletal muscle is still a relatively inefficient and highly variable method of gene transfer. However, published reports have shown that application of an electric field to the muscle immediately(More)
One of the most striking recent advances for plasmid delivery in vivo has been that of electropermeabilization, commonly referred to as electroporation. This physical process exposes a muscle tissue to a brief, high intensity electric field that induces temporary and reversible breakdown of the plasma membrane. During the period of membrane destabilization,(More)
INTRODUCTION There is currently no Food and Drug Administration (FDA)-approved treatment for hypoactive sexual desire disorder (HSDD). FDA approval of products utilizing testosterone has been delayed due to possible safety concerns. Flibanserin, a 5-HT(1A) agonist, 5-HT(2) antagonist, and gepirone-ER, a 5-HT(1A) agonist, have been shown to have activity in(More)
