Helicobacter pylori(H. pylori) infection is a wellestablished risk factor for the development of gastric cancer(GC), one of the most common and deadliest neoplasms worldwide. H. pylori infection induces chronic inflammation in the gastric mucosa that, in the absence of treatment, may progress through a series of steps to GC. GC is only one of several clinical outcomes associated with this bacterial infection, which may be at least partially attributed to the high genetic variability of H. pylori. The biological mechanisms underlying how and under what circumstances H. pylori alters normal physiological processes remain enigmatic. A key aspect of carcinogenesis is the acquisition of traits that equip preneoplastic cells with the ability to invade. Accumulating evidence implicates H. pylori in the manipulation of cellular and molecular programs that are crucial for conferring cells with invasive capabilities. We present here an overview of the main findings about the involvement of H. pylori in the acquisition of cell invasive behavior, specifically focusing on the epithelial-to-mesenchymal transition, changes in cell polarity, and deregulation of molecules that control extracellular matrix remodeling.

DNA vaccines are the third generation vaccines based on purified plasmid preparations containing transgenes that encode antigenic/therapeutic proteins or peptides capable of triggering an immune response against a wide range of diseases. This vaccine platform presents several attributes that confer distinct advantages over other vaccine technologies in terms of safety, ease of fabrication and stability. Many aspects, such as antigen expression and especially vector design, are under study because of their great influence on immunogenicity and efficacy of DNA vaccines. In this regard, with the attempt of improving the efficiency of DNA vaccines, co-expression of stimulatory sequences and diverse vector delivery systems are being optimized. With this in mind, this review aims to giving a conceptual approach of DNA vaccines, explaining their mechanisms of action and listing the already licensed veterinary DNA vaccines presented in the market.
