The isolation and characterization of a new snake venom cysteine-rich secretory protein (svCRiSP) from the venom of the Southern Pacific rattlesnake and its effect on vascular permeability

Abstract: A novel snake venom cysteine-rich secretory protein (svCRiSP), Hellerin, was purified from C. o. helleri venom using sequential reverse phase and cation-exchange chromatography. Gel electrophoresis, N-terminal sequencing, and LC-MS/MS sequencing identified a single protein with a molecular mass of approximately 24.8 kDa and confirmed its identity as a svCRiSP. Hellerin had cytotoxic effects on human umbilical vein endothelial cells (HUVECs) in a dosedependent manner but not in human dermal lymphatic endothelia… Show more

“…svCRiSPs were isolated from crude venoms using two chromatographic steps consist of reverse phase C18 (Higgins Analytical PROTO 300 C18, 250 × 4.6 mm, 5 µ m column, Higgins Analytical, Inc., Mountain View, CA) and cation-exchange (Waters Protein-Pak™ SP 5PW, 7.5 × 75 mm column, Waters Corp., Milford, MA) as previously described [8].…”

“…Venom protein identification and sequence analysis of CRiSPs (Css-CRiSP from C. s. scutulatus, Catrox-CRiSP from C. atrox, Cada-CRiSP from C. adamanteus, Chor-CRiSP from C. horridus, and App-CRiSP from A. p. piscivorus) were performed by LC-MS/MS mass spectrometry following the protocol as described by Suntravat et al [8]. N-terminal amino acid sequences and sequences generated by MS were compared to the sequences in the GenBank database using BLASTX programs.…”

“…The effect of hellerin, from Crotalus oreganus helleri venom, on vascular permeability was demonstrated in vivo and in vitro. Trans-capillary leakage was observed 30 min after mice were subcutaneously injected with hellerin (70 nM), but leakage was approximately half that of the vascular permeability produced by vascular endothelial growth factor A (VEGF-A, 50 nM) [64]. Hellerin (2 M) reduced the viability of HUVECs by 50%, and hellerin-treated HUVEC cells had rounded cell shapes and detached from the substrate.…”
