Description of DPQ

DPQ는 강력하고 혈액-뇌 장벽 투과성이 있는 폴리(ADP-ribose) 폴리머라제-1(PARP-1) 선택적 억제제로 DNA 손상 복구 및 관련 세포 과정을 연구하기 위해 사용된다. DPQ는 급성 폐 손상, 심근 허혈-재관류 손상 및 신경 퇴행성 질환에서 염증 반응과 세포 사멸 메커니즘을 조사하기 위해 적용되고 신경 보호 및 심장 보호 효과를 입증한다 [3-4].

체외 실험에서 비소세포폐암 세포 라인(A549 및 H1299)을 DPQ(1 μM)로 4시간 전처리한 후 탄소이온 조사(0.5–2 Gy)를 24시간 추가로 시행하면 세포 이동, 상처 치유 능력 및 기질금속단백분해효소(MMP-2와 MMP-9)의 활성과 발현이 현저하게 억제되었다 [5]. HeLa 세포를 DPQ(20–150 μM)로 1시간 전처리한 후 PMA(50 nM)로 3시간 자극하면 히스타민 H1 수용체(H1R) 유전자 발현 상향 조절이 현저하게 억제되고 H1R 프로모터 활성도 감소하였다 [6].

체내 실험에서 C57BL/6 쥐에게 신장 허혈 45분/재관류 6시간 전 24시간에 DPQ(15 mg/kg)를 전처리하면 PARP-1 과잉활성을 억제해서 급성 세뇨관 괴사(ATN), 세뇨관 세포 공포화, 브러시 볍체 상실 등 허혈-재관류 관련 병리손상을 감소시켰고 세뇨관 상피 세포 탈락과 캐스트 형성도 개선하였다 [7]. LPS(7.5 mg/kg)로 C57BL/6 쥐를 30분간 전처리한 후 복강내 DPQ(10 μg/kg)를 6시간 주입하면 폐조직의 호중구 침윤과 과산화물효소(MPO) 활성이 현저하게 억제되었고 TNF-α, IL-1β, IL-6 등 염증인자의 mRNA 발현 수준이 감소하였다 [8].

Protocol of DPQ

세포 실험 [1]:

세포 라인

A549 및 H1299 (인간 비소세포 폐암세포), HeLa (인간 자궁경부암세포), MCF7 (인간 유방선암세포)

제조 방법

세포는 10 % 태아소 혈청(FBS)이 보충된 DMEM에서 37 °C, 5 % CO₂ 조건으로 유지하였습니다. 탄소이온(¹²C) 조사 4시간 전에 DPQ(1 μM)를 처리한 후 조사 후에도 DPQ가 포함된 배지에서 배양을 계속하였습니다.

반응 조건

1μM; ¹²C 조사 후 4시간 전처리 (0.5-2Gy)

응용 분야

DPQ는 EGFR, Akt, p38 및 ERK의 인산화를 억제해 NF-κB를 비활성화해서 A549와 H1299 세포의 이동성과 상처 치유 능력을 현저하게 억제하였습니다. DPQ는 MMP-2와 MMP-9 발현도 감소시켰습니다. 게다가 DPQ는 N-cadherin, vimentin, anillin을 하향 조절하고 claudin-1 및 claudin-2를 상향 조절해서 상피-중간엽 전이(EMT)를 억제하였습니다.

동물 실험 [2]:

동물 모형

C57BL/6 쥐 (8–10 주령, 수컷)

제조 방법

쥐에게 LPS(7.5 mg/kg)를 복강내 주입해서 급성 폐 손상을 유발하였습니다. LPS 처리 30분 후 DPQ(1 또는 10 μg/kg)를 복강내 투여하였습니다. LPS 노출 6시간 후 쥐를 희생시켜 폐 조직을 분석하였습니다.

제형

10μg/kg; i.p.; Single injection. 단일 주사.

응용 분야

DPQ 처리는 호중구 침윤 감소와 혈관 투과성 억제를 통해 LPS 유발 급성 폐 손상을 현저하게 완화하였습니다. DPQ는 폐 조직 내 pro-염증 매개체(TNF-α, IL-1β, IL-6, MIP-2, iNOS 및 CXCL-1)의 mRNA 발현을 억제하고 세포 사멸을 감소시켰습니다.
