Abstract
Surface-mediated gene delivery appears to be potential gene delivery modes for various applications. Still, controlled and smart delivery manners are required especially considering the need for gene therapy to deliver gene with selectivity. A surface that can effectively payload DNA, promote cell adhesion, and stimuli response is an important prerequisite. Here, we report a matrix metalloproteinase (MMP)-responsive surface-mediated gene delivery system by combining MMP-degradable hydrogel with a breath figure (BF) porous film. The MMP-degradable hydrogel containing plasmid DNA was loaded into the surface pores of the BF film as DNA reservoirs. The upper surface without hydrogel on the BF film served as footholds of integrin adhesions. MMP is one of the important endogenous signals in tumor-related pathologic changes, and MMP expressions in cancer cells are significantly higher than those in normal cells. Consequently, our surface-mediated gene delivery locally and rapidly released the payload DNA in response to cancer cells and transfected them. This work highlights the importance of the combination of stimuli-response and surface-mediated gene delivery to functional materials, showing good potential applications in the field of gene therapy.

Abstract
Along with the development of life science, the use of transgenic vectors is becoming more and more popular. Besides cloning and expressing target genes, this technology plays an important role in gene diagnosis, gene therapy and new drug development. In this article, we give an overview of transgenic vectors on their classification, characteristics, advantages, disadvantages and applications in the research of gastrointestinal tumors.
