배경 : 대식세포의 거품세포 형성은 동맥경화를 유발하는 주요한 원인으로 보고 되었다. 많은 연구들은 대식세포에 특이적인 프로모터를 보고하였지만 치료용 벡터로 활용하기에는 특이성 및 효율성이 충분하지 않았다. 본 연구에서는 저자가 개발한 대식세포 특이적 합성 프로모터에 adiponectin 유전자를 연결하여 동물 동맥경화 모델에 적용하여 그 효과를 검증하고자 하였다.

방법 : 합성 프로모터 SP-146은 NCBI 웹 사이트[http://www.ncbi.nim.nih.gov/nuccore/DQ107383]에 등록되어 있으며, 비 대식 세포 세포주 (293T, HeLa)와 대식세포 세포주(RAW264.7)에 도입하여 프로모터 활성을 분석하였다. 대식세포 특이성을 증진시키기 위하여 PU.1 인자를 포함하는 p47phox 프로모터의 일부분을 다양한 길이(C1, C2, C3)로 제작하여 합성 프로 모터 뒤에 삽입하였다. RAW264.7 세포에서 분석했을 때, 후보 프로모터들 사이에서 SP146-C1 이 가장 높은 특이성과 효율을 보였고, 최종적으로 이 프로모터가 대식세포 특이적 adiponectin 발현 벡터의 개발에 선택되었다. C1 부위의 PU.1 과 전사 시작 부위 사이의 정확한 서열의 길이가 세포 특이적 활성에 중요한 인자로 여겨진다. Adiponectin 유전자를 치료적 유전자로 선택하여 SP146-C1 vector에 삽입하였다.

결과 : 다양한 세포에서 adiponectin의 특이적 발현을 확인하였고 거품세포 형성 분석을 통해 adiponectin의 기능을 검증하였다. SP146-C1 프로모터의 발현 효율은 CMV 프로모터에 비할 만 하였다. 그러나 플라스미드를 이용한 유전자 치료는 낮은 유전자 도입 효율과 짧은 발현 시간으로 인한 약점을 가지고 있다. 그래서 SP146-C1에 의해 조절되는 GFP 또는 adiponectin 렌티 바이러스를 제작하였고 세포 특이성을 검증하였다. 거품세포 형성을 유도하기 위하여 RAW264.7 세포에 산화된 저밀도 지단백(oxidized LDL, 100㎍/mL)을 1일간 처리하였다. 세포에 축적된 지방의 수준은 Oil red O 염색으로 분석하였다. adiponectin의 과발현은 성공적으로 RAW264.7 세포의 지방 축적을 억제시켰다. 동맥경화반에 대식세포 특이적 adiponectin의 발현이 치료적 효과를 갖는지 검증하기 위하여, ApoE KO 쥐에 partial carotid ligation 수술을 통해 동맥경화를 유발하였고, jugular vein을 통해 SP-APN 렌티바이러스를 투여하였다. SP-APN 바이러스를 처리한 쥐에서 동맥경화반의 크기와 지방 축적 수준이 유의적으로 감소하였고, 대식세포에 특이적으로 adiponectin이 발현하는 것을 확인하였다.

결론 : SP146-C1 프로모터는 P47phox 프로모터와 합성 프로모터 SP146의 조합으로 만들어졌으며 성공적으로 대식세포를 표적함을 증명하였고, 이를 통한 adiponectin의 발현 조절은 동맥경화증의 발생을 억제하였다.
