Abstract:
:To investigate whether in vivo gene transfer causes leptin-antagonistic effects on food intake, animal body weight and fat tissue weight, the R128Q mutated-leptin gene, an R to Q substitution at position 128 of mouse leptin, was transferred into mouse liver and leg muscle by electroporation and hydrodynamics-based gene delivery. Mutated-leptin gene transfer by electroporation caused significant increases in body weight at 5 days and after (5.4% increase relative to control; p<0.05). Hydrodynamics-based gene delivery of the mutated-leptin gene also caused an increase in body weight (3.0% increase relative to control; p<0.05). Mutated-leptin gene transfer by electroporation significantly increased the tissue weight of epididymal white fat and neuropeptide Y mRNA expression in the hypothalamus compared with those of the control group 3 weeks after gene transfer (p<0.05). These results suggest that mutated-leptin gene transfer successfully produced leptin-antagonistic effects by modulating the central regulator of energy homeostasis. Also, the extent of leptin-antagonistic effects by electroporation was much higher than hydrodynamics-based gene delivery, with at least single gene transfer.
