Methods Two human cancer cells were studied: human lung adenocarcinoma, the A549 cell lines exhibiting a high constitutive COX-2 protein expression level and human breast carcinoma, the MCF-7 cells manifesting low expression of the COX-2.COX-2 expression was measured by RT-PCR.

Two COX isomers were found so far, COX-1 and COX-2. COX-1 is a constitutive protein in normal cell and involves in synthesis of prostaglandins and homeostasis of various physiologic functions as a physiologic gate-keeper.

到目前为至，发现COX有2个异构体，COX-1是正常细胞的组成蛋白，参与合成正常细胞活动所需的前列腺素（PGs），起着生理性管家的功能。

The distinction between regulated and constitutive protein secretion pathways at first blush appears obvious.

调节性蛋白和结构性蛋白分泌途径的不同第一眼看过去就很明了。

There was a little increase of plasma constitutive protein synthesis with a significant difference in prealbumin.

本文认为，我国完整合理的环境规制法律体系应该包括三大部分，即：环境行政组织法、环境保护法，以及循环型社会法。

The Legislative law and Constitutive law are of high importance among the other kinds of laws.

在其他法律根据里，《立法法》与组织法是非常重要的法律。

Constitutive promoter was widely used in plant stress resistance genetic engineering to improve stress tolerance of transgenic plants. But constitutive expression of exogenous gene influences plant growth and even leads to infertility.

COX-1 is the constitutive gene, whereas COX-2 is inducible gene. Cytokines, growth factors, oncogenes, and tumor promoters have been found to induce COX-2 up-expression in order to produce prostaglandins ( PGs) for various inflammatory stimulation.

COX-1为组成性基因，COX-2是诱导型基因，受细胞因子、生长因子、癌基因、及肿瘤促进剂的刺激，COX-2表达上调，使其产生对各种炎症做出反应的前列腺素类物质（PGs）。
