Forty-eight hours after transfection, cells were harvested to determine luciferase activity by illuminometer. In the presence of RU486 a 40-fold maximum activation of the luciferase reporter gene was observed in cultured cells, whereas in the absence of RU486, no significant activation was observed. There was a positive correlation between the luciferase activation and RU486 concentration in a definite range. The results showed that the RU486-inducible regulatory vector was successfully constructed, which can be used to regulate the expression level of genes of interest in appropriate time by the inducer RU486. This inducible expression vector provides a platform for the research of gene regulation and gene therapy.

加入诱导剂RU486后，可以诱导表达荧光素酶，并在一定范围内两者呈正比，最高可以实现荧光素酶的40余倍的表达，而没有RU486时，几乎没有报告基因的表达，表明RU486诱导调控载体构建成功，可实现对目的基因的表达时间和表达水平的精确调控，为进一步的基因调控研究和和基因治疗提供了良好的工具。

Inmodel is either a logical vector, whose length is the number of columns in X, or a vector of indices, whose values range from 1 to the number of columns in X, specifying the predictors that are included in the initial model. The default is to include no columns of X.

其中 X 为自变量矩阵， y 为因变量矩阵， inmodel 可以为一个逻辑向量，它的长度为 X 中列向量的个数或者说变量的个数；也可以一个序列向量，它的取值范围为1－ X 中列向量的个数，用来指定模型中的初始变量，默认值是没有选取任何 X 的列向量。

A novel method for design of controller enforcing the constraints is presented. First the constraints involving the marking and Parikh vectors are transformed into the constraints involving Parikh vector only using Petri net state equality, and then the controller is constructed based on the viewpoint that a place can be seen as a linear inequality constraint on the Parikh vector.
