production of recombinant alpha neurotoxin of scorpion venom mesobuthus eupeus and analysis of its immunogenicity
نویسندگان
چکیده
conclusion: the newly produced recombinant protein bmk revealed to be immunogenic. moreover, anti-bmk antibodies produced in mice were able to recognize both the recombinant bmk neurotoxin and the one in m. eupeus crude venome. taken together, the molecular characterization and recombinant production of the iranian scorpion m. eupeus venom component can serve as a new probe for further studies of sodium channels function and physiology. this provides a promising perspective for the future design of selective drugs, as well as for research of antivenom production. results: a novel bmk neurotoxin has been cloned, expressed and characterized from the iranian scorpion m. eupeus venom. we analyzed the recombinant bmk by immunoblotting with treated antiserum. the result showed that mice antiserum can react also with scorpion crude venom, so is able to recognize native bmk toxin. background: scorpion venom is important and rich source of peptides, most of which have been widely used as pharmacological tools for unraveling structure-function relationship of various ion channels. naturally occurring toxins can be also considered as lead compounds in the development of novel drugs. objectives: in this context, the scorpion-derived peptide neurotoxins specific to sodium channels have shown promise as potential therapeutic targets for the treatment of various human diseases. materials and methods: a cdna library from the extracted rna was constructed using rt-pcr and semi-nested rt-pcr. dna sequencing followed by phylogenetic analysis was applied to screen the cdna library clones. for molecular characterization of the bmk gene we used cloning and recombinant protein expression techniques based on e.coli systems. then we performed mice immunization and western blot and immunodot analyses.

متن کاملFirst transcriptome analysis of Iranian scorpion, Mesobuthus eupeus venom gland
Scorpions are generally an important source of bioactive components, including toxins and other small peptides as attractive molecules for new drug development. Mesobuthus eupeus, from medically important and widely distributed Buthidae family, is the most abundant species in Iran. Researchers are interesting on the gland of this scorpion due to the complexity of its venom. Here, we have analyz...

Background: To explore the oral absorption of scorpion venom an ELISA were designed in this study. Scorpions and their venom were been used for centuries as medical treatments in traditional medicine. The oral administration of drug referred as the convenient way, as there was not any publication about gastro-intestinal absorption of scorpion venom; this experiment checked oral absorption of Me...
متن کاملPreparation and biodistribution study of a 99mTc-labeled toxic fraction of Iranian mesobuthus eupeus scorpion venom
Introduction: Iranian scorpion species are classified in Buthidae and Scorpionidae with 16 genera and 25 species. In Iran, similar to other parts of the world, there are a few known species of scorpions responsible for severe envenoming. Mesobuthus eupeus is the most common species in Iran. Its venom contains several toxin fractions which can affect the ion...
