Description of HSF1A

HSF1A는 열 충격 전사 인자 1(HSF1)의 활성제이다. HSF1A는 분자 보호자 TRiC/CCT의 활성을 억제해서 HSF1을 활성화하고 단백질 접힘 오류와 스트레스에 대한 세포의 저항력을 강화한다[2-3]. HSF1A는 주로 신경퇴행성질환을 치료하기 위해 사용된다[4].

CD150⁺CD48⁻LSK 혈구 줄기세포(HSCs)에서 HSF1A(8μM; 10일)는 체외 배양된 HSCs의 연쇄 재구성 활성을 강화한다[5]. 중국 햄스터 난소에서 HSF1A(200µM; 1시간)는 세포를 백일해 독소에 의한 세포독성으로부터 보호한다[6].

위스타 교토 쥐에서 HSF1A(100mg/kg; 복강주사; 4주)는 체내 실험에서 독소루비신 유도 심부전을 개선한다[7]. Ovalbumin 유도 알레르기 천식 쥐 모델에서 HSF1A(1.3g/kg; 경구 투여; 5주) 치료는 염증과 산화 스트레스를 줄일수 있고 기도 섬유화를 현저하게 감소시킨다[8].

Protocol of HSF1A

세포 실험 [1]:

세포 라인

CD150+CD48-LSK 조혈 줄기세포 (HSCs)

제조 방법

젊은 성인 쥐의 골수로부터 CD150⁺CD48⁻LSK HSCs를 96웰 v-bottom 판에 직접 분리해서 10 세포/웰의 밀도로 신선하게 만든 기본 HSC 배양액(Prime-XV Mouse Hematopoietic Cell Medium)을 넣었습니다. 이 배양액에는 SCF(50ng/ml), TPO(50ng/ml), 2-Mercaptoethanol(50μM)과 소우유 알부민(BSA; 0.1%)이 들어 있었습니다. 지정된 경우 기본 HSC 배양액은 0.02% DMSO에 녹인 17-AAG(5nM) 또는 HSF1A(8μM)를 보충하였습니다. 대조 그룹으로서 기본 HSC 배양액은 0.02% DMSO를 보충하였습니다.

반응 조건

8μM; 10 일 동안

응용 분야

HSF1A는 체외 배양된 HSCs의 연쇄 재구성 활성을 강화합니다.

동물 실험 [2]:

동물 모형

위스타 교토 쥐

제조 방법

10주령된 위스타 교토 쥐(WKY)를 사용하였습니다. 흰쥐들은 상수 온도(22℃)에서 12시간 주/야 주기로 사육되었고 사료와 자수를 제공받았습니다. 동물들은 세 그룹으로 나뉘었습니다: WKY 쥐(대조 그룹), 아르미실린(DOX) 쥐 그리고 HSF1A로 처리된 DOX 쥐. 각 그룹은 다섯 마리의 동물을 포함하였습니다. DOX 그룹은 6주 동안 연속적으로 아르미실린(DOX; 5mg/kg)을 복강 주사 받았고 심장 독성이 증명된 30mg/kg의 누적 투여량에 달하였습니다. HSF1A는 소 분자 HSF1 활성제로 복강 주사(100mg/kg/일)로 투여되었습니다.

제형

100mg/kg; ip; 4 주 동안

응용 분야

HSF1A는 체내에서 아르미실린 유도 심부전을 개선합니다.
