Cre/loxP和FLP/FRT系统介导位点特异性DNA重组,越来越多地被用于体内基因功能的研究。这些系统允许在体内对单一细胞类型的基因进行靶向破坏,从而允许研究来自特定细胞类型的给定基因产物的生理和病理生理学影响。在肾脏中,Cre/loxP系统被用来选择性地在集合管的主细胞内实现基因缺失。破坏收集管道中的靶基因,如内皮素-1或多囊肾病-1(PKD-1),可能导致对这些基因产物的生物学作用的重要洞察。通过选择合适的肾细胞特异性启动子,这些重组系统可以用来针对几乎任何类型的肾脏细胞的基因破坏。尽管利用这些重组系统的转基因研究前景看好,但它们还处于相对初级阶段,可能既耗时又昂贵,并产生意想不到的结果。预计这些系统的持续经验将为分析肾脏健康和疾病中的基因功能提供重要工具。
The Cre/loxP and Flp/FRT systems mediate site-specific DNA recombination and are being increasingly utilized to study gene function in vivo. These systems allow targeted gene disruption in a single cell type in vivo, thereby permitting study of the physiological and pathophysiological impact of a given gene product derived from a particular cell type. In the kidney, the Cre/loxP system has been employed to achieve gene deletion selectively within principal cells of the collecting duct. Disruption of target genes in the collecting duct, such as endothelin-1 or polycystic kidney disease-1 (PKD1), could lead to important insights into the biological roles of these gene products. With selection of the appropriate renal cell-specific promoters, these recombination systems could be used to target gene disruption to virtually any renal cell type. Although transgenic studies utilizing these recombination systems are promising, they are in their relative infancy and can be time consuming and expensive and yield unanticipated results. It is anticipated that continued experience with these systems will produce an important tool for analyzing gene function in renal health and disease.
