Objective To study the distribution of G protein-coupled receptor kinase ( GRK) in rats' hypothalami and its role in the secretion of corticotrophin-releasing hormone ( CRH) early after severe trauma.

There are 7 members in the GRK family ( GRK1-7), which can be categorized into 3 subfamilies.

GRK有七种亚型（GRK1-7），分为三个亚家族。

Agonists for GPCR can regulate the expression level of GRK, and the abnormal expression of GRK in vivo can markedly influence physiological functions of organs and tissues.

GRK的表达水平可被GPCR的激动剂调节。GRK在体内的异常表达可以严重地影响器官和组织的功能。

The GRK 2/ 3 and the mRNA of CRH were measured by Western blot and reverse transcriptional polymerase chain reaction ( RT-PCR) respectively.

通过western blot实验研究室旁核GRK2/3的蛋白表达，逆转录多聚酶链反应（RT-PCR）技术研究室旁核CRH的转录活性。

Arrestin is an important soluble protein that mediates receptor desensitization which is found after G protein coupled receptor kinase ( GRK).

Arrestins是继G蛋白偶联受体激酶（GRK）之后发现的另一个中介受体脱敏的重要可溶性蛋白。

Effect of GRK 2/ 3 on the regulation of CRH secretion in hypothalamic paraventricular nucleus of rats

Previous research mainly focused on the regulatory functions of GRK in differentiated cells and maturely developed organs.

以往的研究主要集中在GRK对分化、发育成熟的机体、组织的调节功能上，GRK在发育过程中的作用还研究得较少。
