工作总结：已经产生了考克斯-1和考克斯-2缺陷的小鼠。这些小鼠被用于确定个体考克斯同种型的生理作用，并阐明两种同种型单独或联合作用的方式。这两种亚型缺陷的小鼠在动脉导管未闭出生后不久死亡，但在其他方面表现正常。我们已经发现考克斯-2是主要负责导管闭合的同种型，并且在导管的收缩的光滑肌中诱导考克斯-2，而不是考克斯-1。在进一步的研究中，我们证明了考克斯-1或考克斯-2选择性抑制剂重复了用COC敲除小鼠获得的结果。
英文摘要
Summary of Work: Mice deficient in both COX-1 and COX-2 have been produced. These mice are being used to determine the physiological roles of the individual COX isoforms and to elucidate the ways in which the two isoforms act individually or in conjunction. Mice deficient in both isoforms die shortly after birth of patent ductus arteriosus, but otherwise appear developmentally normal. We have found that COX-2 is the isoform primarily responsible for the closure of the ductus and that COX-2, but not COX-1, is induced in the contracting smooth mucles of the ductus. In further studies, we have demonstrated that COX-1 or COX-2 selective inhibitors duplicate the results obtained with the COC knockout mice.
