This study aimed the role of gold nanoparticles (AuNP) in advanced glycation end-products (AGEs) induced migration and invasion in bovine retinal endothelial cells (BRECs). BRECs were isolated from the retina. Cell viability was confirmed by the MTT assay. In vitro wound migration assay was performe...

AuNP는 어떤 물질인가? | 2006). AuNP는 생체적합성을 가지며, 표면 플라스몬 공명 흡수대에 의한 특성분석과 합성이 쉬운 점 등에서 가능성이 큰 물질이다. 특히 금은 약한 산성으로서 티올, 아민과 같은 약한 염기와 강하게 결합하며, 시스테인과 라이신 잔기를 가진 단백질들이 AuNP와 결합하여 그들의 생물학적 기능이 변하게 된다(Resham and Pribyabrata 2008). | |
최종당화산물이란 무엇인가? | 최종당화산물(advanced glycation end-products, AGEs)은 당뇨를 가속화하고, 당뇨의 합병증 예를 들어 망막병증(retinopathy)과 같은 합병증과도 연관이 큰 거대 단백질이다(Stitt and Curtis 2005). 많은 혼합물 중 pensosidine과 methylglyoxal 유도체인 N-carboxymethy-lysine (CML), N-carboxyethyl-lysine (CEL)은 잘 알려지고 연구되어진 AGEs 중 하나이다(Moore et al. | |
BRECs에서 AGEs로 유도된 세포의 이동 및 침윤에 있어서 AuNP의 역할에 관한 연구 결과는? | AuNP의 apoptosis 유도는 caspase-3 assay를 통해 확인하였다. AGE-BSA은 세포증식 및 이동에 있어서 증가함을 보여주었다. 또한 AuNP는 AGE-BSA 존재 유무에 상관없이 세포의 증식, 이동, 신생혈관 형성을 억제하였고, caspase-3을 통해 apoptosis를 유도하였다. 이러한 결과, AuNP는 AGE로 유도된 신생혈관 형성 및 세포의 이동성을 억제하는 약재제로서, 당뇨성 합병증에 있어서 잠재적으로 중요한 분자가 될 것이다. |
