23 Jul Method for activating expression of erythrogenin genes
Abstract
The invention relates to the field of biotechnology, and particularly relates to a method for activating the expression of erythrogenin genes, namely, activating the expression of erythrogenin genes in target cells by using a TALE technology. The method comprises the following steps: 1) searching a TALE target spot sequence at the upstream of an erythrogenin gene promoter, and designing a target spot identification module which is used for specifically identifying the TALE target spot sequence and composed of TAL nucleic acid identification units; 2) building a coding sequence of the target spot identification module; 3) connecting the coding sequence of the target spot identification module prepared in the step 2) with a skeleton carrier by using an enzyme digestion and connection method so as to obtain a recombinant plasmid; 4) transforming the recombinant plasmid to a target cell and culturing the cell. According to the invention, the expression of erythrogenin genes is activated in autologous mesenchymal stem cells by using a TAL technology, so that the method provides a new source of cells for gene therapy, and can play an important role in tissue engineering and cell therapy.
