Abstract:
본 발명은 노닐페놀에 의해 유도된 생식계 독성을 이용한 노닐페놀 노출 여부 확인용 miRNA 마이크로어레이 키트,이를 이용한 노닐페놀 노출 여부 확인 방법 및 이의 검출 방법에 관한 것으로, 구체적으로 노닐페놀이 처리된 정소 유래의 세르톨리 세포에서 마이크로어레이 칩을 이용하여 NP에 의해 특이적으로 그것의 발현이 증가 또는 감소하는 miRNA를 이용하여 노닐페놀 노출 여부를 확인하는 방법에 관한 것이다. 본 발명의 miRNA는 마이크로어레이를 통하여 노닐페놀의 노출에 의해 유발되는 생식독성의 작용 기작을 규명하는데 유용하게 사용될 수 있다. 내분비 장애물질 중 하나인 노닐페놀에 대한 miRNA의 조절은 거의 밝혀져 있지 않으며, 독성물질에 의해 변화하는 유전자의 발현을 조절하는 miRNA의 동정은 독성 평가를 위한 새로운 툴이 될 수 있을 것으로 기대된다. miRNA에 대한 예측된 표적 유전자의 포괄적인 분석은 세포 분열, 세포 주기 및 세포 사멸에 기능을 하는 유전자들의 발현이 노닐페놀-처리된 TM4 세포에서 miRNA에 의해 조절된다는 것을 보여준다.
