Abstract
Description
도 2a 내지 2c는 화학적으로 변형된 sgRNA가 1차 인간 T 세포 및 CD34+ 조혈 줄기 및 전구 세포(HSPC)에서 높은 비율의 유전자 파괴를 촉진함을 보여준다. 100만개 1차 인간 T 세포를 10 ㎍의 표시된 합성 sgRNA 및 15 ㎍ Cas9 mRNA 또는 1 ㎍ Cas9-암호화 플라스미드로 핵내도입시켰다(도 2a). sgRNA 및 Cas9 단백질을 둘 다 암호화하는 플라스미드 1 ㎍을 비교를 위해 포함시켰다. 막대들은, sgRNA 표적 부위에 걸쳐있는 PCR 앰플리콘의 TIDE 분석에 의해서 및 기준 대조군으로서 모의-처리 샘플을 사용하여 측정된 바와 같은 3명의 상이한 공여체들에 대한 평균 in/del 빈도 +SEM, n=6을 나타낸다. 도 2b에서는, 2.5 몰 과량의 표시된 합성 CCR5 sgRNA와 사전-복합체화된 15 ㎍ Cas9 단백질을 사용한 것을 제외하고, 자극된 T 세포를 상기와 같이 핵내도입시켰다. in/del 빈도는 상기와 같이 TIDE 분석에 의해 측정하였다. 막대들은 3명의 상이한 공여체들에 대한 평균 in/del 빈도 + SEM, n=6을 나타낸다. 도 2c에서는, 500,000개의 가동화된 인간 말초혈 CD34+ HSPC를 IL2RG 또는 HBB를 표적화하는 표시된 합성 sgRNA 10 ㎍ 및 15 ㎍ Cas9 mRNA 또는 1 ㎍ Cas9 플라스미드로 핵내도입시켰다. sgRNA 및 Cas9 단백질을 둘 다 암호화하는 sgRNA 플라스미드 1 ㎍을 비교를 위해 포함시켰다. 막대들은 T7 엔도뉴클레아제 절단 분석에 의해 측정된 바와 같은 평균 in/del 빈도 +SEM, n=3을 나타낸다. 도 2d에서는, 100만개의 자극된 T 세포 또는 가동화된 인간 말초혈 CD34+ HSPC를 15 ㎍ Cas9 mRNA 및 10 ㎍의 표시된 합성 CCR5 sgRNA로 핵내도입시켰다. 함께 사용된 경우, 각각의 sgRNA의 양은 5 ㎍이었다. 단일 sgRNA를 갖는 샘플에 대한 in/del 빈도는 상기와 같이 TIDE 분석에 의해 측정하였고, 2개의 sgRNA를 갖는 샘플에 대한 in/del 빈도는 클로닝된 PCR 산물의 서열분석에 의해 측정하였다(도 18a 및 18b 참조). 막대들은 평균 in/del 빈도 +SEM, n=3을 나타낸다.
도 3은 시험관 내에서 화학적으로 변형된 sgRNA에 의해 유도된 dsDNA 표적들의 Cas9 절단을 보여준다. 막대들은 Cas9 단백질 및 sgRNA로 처리된 표적 DNA 단편들(도 4 참조)의 절단 생성물들의 % 수율을 나타낸다. 각 sgRNA의 3개의 독립적인 합성물들에 대한 평균값 +SEM을 나타내었다.
도 4는 시험관 내에서 화학적으로 변형된 sgRNA에 의해 유도된 dsDNA 표적들의 Cas9 절단을 보여준다. dsDNA 표적들의 생화학적 절단으로부터 수득된 절단 생성물들은 바이오어낼라이저(Bioanalyzer) 2200 상의 DNA 7500 랩칩(LabChip) 상에서 분석하였다. 대표적인 겔들을 각각의 표적에 대해 나타내었고, 추가의 복제물들은 도 3에 도표화된 결과들에 포함되어 있다. 샘플들은 다음과 같았다: (L): 래더(ladder), (1): 비변형 sgRNA + 표적 DNA(-Cas9 모의 처리됨), (2): 표적 DNA + Cas9 단백질(-sgRNA 모의 처리됨), (3): 비변형 sgRNA + 표적 DNA + Cas9 단백질, (4): M sgRNA + 표적 DNA + Cas9 단백질, (5): MS sgRNA + 표적 DNA + Cas9 단백질, 및 (6) MSP sgRNA + 표적 DNA + Cas9 단백질.
