Th components reported no critical unwanted side effects related together with the angiogenesis agent.34 Although the present study did not particularly address systemic reactions and unwanted side effects of your VEGF gene therapy, we didn’t observe any indicators of distress, transform in behavior, neovascularization of nontargeted tissues or malignancy, and there have been no animal deaths associated with gene transfection. In our preceding study, we demonstrated that rhVEGF165 mRNA is expressed in ulcerated gastric tissue only transiently and disappeared from 7 days just after plasmid injection.15 Consequently, the respective protein couldn’t be synthesized beyond this time point, whereas currently synthesized protein might be degraded. This could clarify our acquiring that rhVEGF165 protein was expressed only at day 7, but not at day 14, following plasmid injection. Mainly because VEGF acts both as a mitogen as well as a survival issue for endothelial cells,35,36 it can be unlikely that discontinuation from the plasmidspecific VEGF protein expression was as a result of the enhanced cell turnover. In addition, expression of plasmid-specific VEGF protein was restricted to the granulation tissue of your ulcer bed. Hence, transient neighborhood expression of VEGF from a transgene may well represent a preferable new therapeutic approach within the CXCL17 Proteins Recombinant Proteins therapy of esophageal ulcers. This study was performed in an animal model of esophageal ulceration caused by serosal application of acetic acid. In humans, esophageal ulcers normally are presented as a complication of reflux esophagitis. In patients with reflux esophagitis and esophageal ulcers, frequent exposure on the ulcer base to gastric contents may perhaps adversely affect the outcome of VEGF gene therapy. Hence, our findings can not be straight translated into clinical esophageal ulcers. It should be pointed, however, that the morphological characteristics of acetic acid-induced esophageal ulcers in rats are very comparable to these of human esophageal ulcers,6 which suggests that, irrespective of the cause, once the ulcer develops, it undergoes comparable frequent stages of repair and healing. The outcomes of the present study indicate that esophageal ulceration triggers induction of HIF-1 protein expression and activation with the VEGF gene and that angiogenesis is an vital component of esophageal ulcer healing. Our demonstration that VEGF gene therapy significantly accelerates healing of experimental esophageal ulcers may well deliver a rationale for future clinicalstudies aimed at evaluating the efficacy of gene therapy with angiogenic development elements for the treatment of esophageal ulcers.
