Abstract
본 발명에 따른 miRNA는 AF 환자에서 유의하게 하향 조절되고, 칼슘 처리 단백질인 CaMKII의 발현 수준 조절을 통해 심근 세포의 손상을 억제하는 바, 이를 AF의 진단 방법 및 CamKII의 발현 수준 조절 효과에 기반한 심방세동의 예방 또는 치료 용도로 제공할 수 있다.
Description
도 2는 HL-1 세포에서 Ca2+ 과도 현상의 마이크로어레이 및 분석 결과를 나타낸 도이다. (A) SR 및 AF 환자의 소변에 대한 miRNA 마이크로어레이 분석의 히트 맵. (B) SR과 AF 환자 사이의 miRNA 화산 플롯. 파란색 점은 AF 샘플에서 하향 조절된 miRNA를 나타내고 빨간색 점은 상향 조절된 miRNA를 나타내었다. (C 및 D) 환자 및 세포에서 7개의 miRNA의 실시간 PCR. AF 환자 및 AF 세포 모델에서 miR-423-5p의 발현은 각각 SR 및 대조군 세포보다 유의하게 낮았다. (E) 세포 내 칼슘 표시기 Fluo-4 AM으로 로드된 세포의 시간 경과 칼슘 이미징의 대표적인 라인 스캔. 그룹에 따른 자발적인 Ca2+ 과도 현상의 대표적인 기록. (F) Ca2+ 과도 진폭 및 주파수 요약. 진폭은 miR-423을 처리한 대조군과 Ang II를 처리한 그룹에서 유의하게 증가하였다. *P<0.001 vs. 스튜던트 t-검정에 따른 대조군. n=5
도 3은 Ang II 유도 HL-1 세포에서 CaMKII, PLB 및 RyR2 활성에 대한 miR-423의 억제 효과를 나타낸 도이다. (A) CaMKII(Thr 287, Thr 306), PBL(Thr17), SERCA2a 및 RyR2(Ser 2814, Ser 2808)의 웨스턴 블롯 분석. (B-F) Ang II 처리 HL-1 세포 및 miR-423 억제제 처리 그룹에서 p-CaMKII, p-PLB 및 p-RyR2의 유의한 증가를 나타내는 단백질 정량화. miR-423 처리군에서는 이들 단백질의 인산화가 감소하였다. 그룹당 n=5-6. *P<0.001 vs. 대조군. 데이터는 평균 ± SEM으로 표시되었다.
도 4는 면역형광 공초점 현미경 이미지를 나타낸 도이다. (A) miR-423은 대조군 + miR-423 억제제 그룹, Ang II 그룹 및 Ang II + miR-423 억제제 그룹에서 CaMKII 인산화를 활성화하지만 Ang II + miR-423 그룹은 활성화하지 않았다. 열은 다음과 같다: 총 CaMKII(빨간색), p-CaMKII(녹색) 및 DAPI(파란색). 배율: Х400. (B) p-CaMKII 강도의 정량적 분석.
