Summary:The present invention relates to an oral composition for preventing, treating or alleviating obesity. It is confirmed that the oral composition can effectively induce the expression of GLP-1 genes in vivo by combining nine amino acids Arginine having positive ion properties to Fc part C-terminal to condense the same with GLP-1 genes having negative ion properties, and also protects genes from disintegration due to immune action of gastric acid and leukocytes during oral administration, thereby enabling gene delivery to a small intestine. In addition, the oral composition is confirmed to have a possibility of long-term treatment effect since a half-life is relatively long when genes are expressed in the small intestine. Therefore, by effective delivery of GLP-1, the oral composition is expected to be useful for preventing, treating, or alleviating obesity. 본 발명은 비만의 예방, 치료 또는 개선용 경구 조성물에 관한 것으로서, 양이온성 성질을 지니는 아미노산 Arginine 9개를 Fc 부분 C-terminal에 결합시켜 음이온성 성질을 지닌 GLP-1 유전자와 응축시킴으로써, 체내에서 GLP-1 유전자의 발현을 효과적으로 유도할 수 있으며, 또한, 경구 투여 시 위산 및 백혈구의 면역작용으로 인한 분해작용으로 부터 유전자를 보호하여 소장까지 유전자 전달이 가능할 뿐만 아니라, 상기 소장에서 유전자가 발현되면 반감기가 상대적으로 길어 장기간 치료 효과 가능성을 확인하였는바, GLP-1의 효과적인 전달을 통해서, 비만의 예방, 치료 또는 개선 용도로 유용하게 이용될 수 있을 것으로 기대된다.
