Genetic therapy holds great promise for the treatment of inherited or acquired
genetic diseases; however, its breakthrough is hampered by the lack of suitable
gene delivery systems. Dumbbell-shaped DNA minimal vectors represent an
attractive, safe alternative to the commonly used viral vectors which are fraught
with risk, but dumbbell generation appears to be costly and time-consuming. We
developed a new PCR-based method for dumbbell production which comprises only two
steps. First, PCR amplification of the therapeutic expression cassette using
chemically modified primers to form a ready-to-ligate DNA structure; and second,
a highly efficient intramolecular ligation reaction. Compared with conventional
strategies, the new method produces dumbbell vectors more rapidly, with higher
yields and purity, and at lower costs. In addition, such produced small hairpin
RNA expressing dumbbells triggered superior target gene knockdown compared with
conventionally produced dumbbells or plasmids. Our novel method is suitable for
large-scale dumbbell production and can facilitate clinical applications of this
vector system.
