The 3MT® competition celebrates the exciting research conducted by graduate students. Developed by The University of Queensland (UQ), the exercise cultivates students’ academic, presentation, and research communication skills. The competition supports their capacity to effectively explain their research in three minutes, in language appropriate to a non-specialist audience. The first 3MT® competition was held at the University of Queensland in 2008 with 160 students competing. In 2009 and...

Developed by The University of Queensland (UQ), the exercise cultivates students’ academic, presentation, and research communication skills. The competition supports their capacity to effectively explain their research in three minutes, in language appropriate to a non-specialist audience. The first 3MT® competition was held at the University of Queensland in 2008 with 160 students competing. In 2009 and 2010 the 3MT® competition was promoted to other Australian and New Zealand universities and enthusiasm for the concept grew. Since 2011, the popularity of the competition has increased and 3MT® competitions are now held in over 170 universities across more than 18 countries worldwide.

- Title
- A conserved cysteine framework of toxins from Viola tricolor and Conus brunneus characterized in the Drosophila melanogaster Giant Fiber System.

- Abstract/Description
-
Conotoxins are disulfide rich peptides present in the venom of cone snails, a genus of marine mollusks that prey upon fish, worms, and other mollusks. Conotoxins are promising drugs leads with great prospects in the treatment of diseases and disorders such as chronic pain, multiple sclerosis and Parkinson’s and Alzheimer’s diseases. Similar compounds can be found in plants; for example, cyclotides, which are cyclic peptides isolated from the Violaceae violet, Rubiaceae coffee, and...
Show moreConotoxins are disulfide rich peptides present in the venom of cone snails, a genus of marine mollusks that prey upon fish, worms, and other mollusks. Conotoxins are promising drugs leads with great prospects in the treatment of diseases and disorders such as chronic pain, multiple sclerosis and Parkinson’s and Alzheimer’s diseases. Similar compounds can be found in plants; for example, cyclotides, which are cyclic peptides isolated from the Violaceae violet, Rubiaceae coffee, and Cucurbitaceae cucurbit families and they have a wide range of biological activities, such as anti-HIV, uterotonic, and antimicrobial. Cyclotides have a cyclic cysteine knot motif characterized by a cyclic backbone and six conserved cysteine residues that form the three disulfide bridges of the “knot”. This motif provides cyclotides with superior stability against thermal, chemical, and enzymatic degradation; marking them as potential frameworks for peptide drug delivery. Cysteine framework IX conotoxins C-C-C-CXC-C, isolated from the venom of Conus brunneus, contain the same cysteine framework, homologous sequences, and similar 3D structures to cyclotides. Presented are details on the isolation of these conotoxins and cyclotides, from Viola tricolor, and the characterization of their activity in the Drosophila melanogaster Giant Fiber System GFS, which contains GAP, acetylcholine, and glutamate synapses.

- Abstract/Description
-
The use of peptide drugs has gained popularity recently. Peptides are attractive drug targets due to their high specificity and potency towards their biological targets. A drawback for peptide drugs is a lack of stability for oral delivery. Two classes of disulfide-rich peptides, conotoxins and cyclotides, have been shown to have higher stability than linear peptides thanks to their disulfide connectivity. Conotoxins are present in the venom of cone snails, a carnivorous marine mollusk that...
Show moreThe use of peptide drugs has gained popularity recently. Peptides are attractive drug targets due to their high specificity and potency towards their biological targets. A drawback for peptide drugs is a lack of stability for oral delivery. Two classes of disulfide-rich peptides, conotoxins and cyclotides, have been shown to have higher stability than linear peptides thanks to their disulfide connectivity. Conotoxins are present in the venom of cone snails, a carnivorous marine mollusk that preys upon fish, worms, or other mollusks. Conotoxins are promising drugs leads with great prospects in the treatment of diseases and disorders such as chronic pain, multiple sclerosis and Parkinson’s and Alzheimer’s diseases. Cyclotides, which are cyclic cysteine knot containing peptides, isolated from the Violaceae (violet), Rubiaceae (coffee), and Cucurbitaceae (cucurbit) families and they have a wide range of biological activities, such as anti-HIV, uterotonic, and antimicrobial. P-superfamily framework IX conotoxins (C-C- C-CXC- C) contain the same cysteine framework, homologous sequences, and similar 3D structures to cyclotides. The knot containing conotoxins have been identified in several Conus species, but this work focuses on those from Conus brunneus, Conus purpurascens, and Conus gloriamaris. The cysteine knot motif of cyclotides and P-superfamily conotoxins is characterized by a cyclic backbone and six-conserved cysteine residues that form the three-disulfide bridges of the “knot”. This motif provides cyclotides and conotoxins with superior stability against thermal, chemical, and enzymatic degradation; marking them as potential frameworks for peptide drug delivery. Presented are details on the isolation of conotoxins and cyclotides, from Viola tricolor, and the characterization of their activity in the well-characterized Drosophila melanogaster giant fiber system (GFS) neuronal circuit, which contains GAP, acetylcholine, and glutamate synapses. The transcriptomes of two Conus brunneus specimens were assembled and mined for P-superfamily framework IX conotoxins. Eleven mature P-superfamily framework IX conotoxins were identified in the crude venom.
