In silico design and validation of conotoxin-based peptides for neuroblastoma nanotherapy
 Mokrý, Michal ; Gumulec, Jaromír (oponent) ; Heger, Zbyněk (vedoucí práce)
This thesis is focused on in silico design and validation of peptides based on -MrIA conotoxin from Conus marmoreus marine snail species, and their possible use in the treatment of neuroblastoma through norepinephrine transporter targeting. Five conotoxin-based peptides were designed using molecular dynamics simulations, and their trajectories were analyzed to determine peptide properties. Two homology models of human norepinephrine transporter were prepared for further analysis of binding properties of the conotoxin-based peptides to norepinephrine transporter. Peptides were synthesized and used to coat apoferritin nanoparticles with cytotoxic agent ellipticine trapped inside apoferritin’s cavity. Created peptides and nanoparticles were analyzed to determine their physico-chemical characteristics. Furthermore, cellular uptake and cytotoxicity towards neuroblastoma and epithelial cell lines were studied. From both in silico and in vitro studies, it appears that YKL-6 peptide is the best candidate for further research.
