عنوان انگلیسی 3’-RACE Amplification of Aminopeptidase N gene From Anopheles stephensi Applicable in Transmission Blocking Vaccines
چکیده انگلیسی مقاله Background: Because of the lack of an effective and economical control strategy against malaria (the most devastating infectious disease in developing countries) Transmission-Blocking Vaccines (TBVs) concept has been raised in recent years, promising a more efficient way to malaria control. TBVs aim at interfering and/or blocking pathogen development within the vector, halting transmission to non-infected vertebrate host. Aminopeptidase N (APN) is one of the most potent proteins in parasite development in Anopheles malaria vectors, which is strongly co-localized with human malaria parasites in the mosquito midgut epithelium. Therefore, Aminopeptidase N is one of the best choices for a new TBV. Methods: In this study for the first time we used 3'-RACE to amplify APN gene in Anopheles stephensi (An.stephensi), a major malaria vector in Iran, Indian subcontinent up to China by using different sets of primers including exon junction, conserved and specific region primers. Results: Full length of APN was sequenced stepwise, which could be applied in designing a new regional TBV and act as an essential component of malaria elimination program in An. stephensi distribution areas. Conclusion: Primers design and method modification should be set up exactly in approach based amplifications. From results we came to this conclusion that that 3'-RACE could be applied to amplified key regions which are be-yond reach.
