Optimization of ultrasound parameters for microbubble-nanoliposome complex-mediated delivery
PURPOSE The aim of this study was to identify the optimal ultrasound (US) parameters for gene and drug delivery. METHODS In order to target SkBr3, which is a breast cancer cell overexpressing the Her2 receptor, trastuzumab (Herceptin) was used. Micobubble-nanoliposome complex (MLC) was mixed with trastuzumab and stored overnight. Finally, MLC was combined with Her2Ab. A US device equipped wit...
متن کاملOptimization of transfection parameters for ultrasound/SonoVue microbubble-mediated hAng-1 gene delivery in vitro.
This study aimed to explore the effects of microbubble concentration, gene dosage, cell-microbubble mixing mode and fetal bovine serum (FBS) on gene delivery. 293T cells were transfected with Sonovue microbubbles carrying the hAng-1 gene via ultrasound irradiation. Various ultrasound exposure parameters and microbubble and DNA concentrations were investigated. In addition, FBS and the cell susp...
متن کاملOptimization of ultrasound parameters for cardiac gene delivery of adenoviral or plasmid deoxyribonucleic acid by ultrasound-targeted microbubble destruction.
OBJECTIVES This study was undertaken to optimize echocardiographic parameters for successful gene delivery to the heart and to extend the method from adenoviral to plasmid deoxyribonucleic acid (DNA). BACKGROUND We have previously shown that ultrasound-targeted microbubble destruction can direct tissue expression of adenoviral transgenes to the heart. The optimal echocardiographic parameters ...
متن کاملUltrasound/Magnetic Targeting with SPIO-DOX-Microbubble Complex for Image-Guided Drug Delivery in Brain Tumors
One of the greatest challenges in the deployment of chemotherapeutic drugs against brain tumors is ensuring that sufficient drug concentrations reach the tumor, while minimizing drug accumulation at undesired sites. Recently, injection of therapeutic agents following blood-brain barrier (BBB) opening by focused ultrasound (FUS) with microbubbles (MBs) has been shown to enhance drug delivery in ...
متن کاملMyocardial delivery of colloid nanoparticles using ultrasound-targeted microbubble destruction.
AIMS Ultrasound (US)-targeted microbubble destruction (UTMD) is a promising method for delivering genetic material to the heart. The aim of this study was: (i) to test whether colloid nanoparticles can be delivered to the rat myocardium using UTMD; and (ii) to determine whether tissue damage and contractile dysfunction occurs in hearts exposed to UTMD in vivo. METHODS AND RESULTS Hearts from ...
