A new electroporation protocol using combined high and low voltage pulses efficiently delivers DNA to skeletal muscle in dogs. This method is faster than traditional techniques and shows potential for clinical gene therapy applications.

Area of Science:

Biomedical Engineering
Molecular Biology
Veterinary Medicine

Background:

Electroporation is used for DNA delivery into skeletal muscle.
Previous protocols often used low voltage pulses.
High and low voltage pulse combinations were suggested for improved efficiency.

Purpose of the Study:

To evaluate electroporation protocols for DNA electrotransfer in canine skeletal muscle.
To compare a novel high/low voltage pulse protocol against standard low voltage protocols.
To assess the feasibility, efficacy, and safety of muscle-targeted gene therapy in dogs.

Main Methods:

Two DNA plasmids encoding green fluorescent protein and human interleukin-12 were used.
Five electroporation protocols were tested: three with high/low voltage combinations and two with low voltage only.

Transfection efficiency and side effects were evaluated in experimental animals.

Main Results:

A protocol combining 1 high voltage pulse followed by 4 low voltage pulses achieved transfection efficiency comparable to standard low voltage protocols.
This optimized protocol was quicker to perform.
Detectable systemic expression of human interleukin-12 was observed.
Mild, transient local side effects occurred, with no clinically detectable systemic side effects.

Conclusions:

Electroporation is a feasible and effective method for muscle-targeted gene therapy in dogs.
The novel high/low voltage pulse protocol is efficient, faster, and safe.
This technique holds potential for clinical applications in veterinary medicine.
