Venom is an important genetic development crucial to the survival of scorpions for over 400 million years. We studied the evolution of the scorpion venom arsenal by means of comparative transcriptome analysis of venom glands and phylogenetic analysis of shared types of venom peptides and proteins between buthids and euscorpiids. Fifteen types of venom(More)
BACKGROUND The family Euscorpiidae, which covers Europe, Asia, Africa, and America, is one of the most widely distributed scorpion groups. However, no studies have been conducted on the venom of a Euscorpiidae species yet. In this work, we performed a transcriptomic approach for characterizing the venom components from a Euscorpiidae scorpion, Scorpiops(More)
The pace of resistance against antibiotics almost exceeds that of the development of new drugs. As many bacteria have become resistant to conventional antibiotics, new drugs or drug resources are badly needed to combat antibiotic-resistant pathogens, like methicillin-resistant Staphylococcus aureus (MRSA). Antimicrobial peptides, rich sources existing in(More)
The misuse of antibiotics has led our age to a dangerous edge, as antibiotic-resistant pathogens appear to evolve more quickly than antibiotics are invented. Thus, new agents to treat bacterial infection are badly needed. Cationic host defense peptides are on the first line of a host defense system and are thought to be good candidates for treating(More)
Scorpion venoms contain a vast untapped reservoir of natural products, which have the potential for medicinal value in drug discovery. In this study, toxin components from the scorpion Heterometrus petersii venom were evaluated by transcriptome and proteome analysis.Ten known families of venom peptides and proteins were identified, which include: two(More)
BACKGROUND Kunitz-type venom peptides have been isolated from a wide variety of venomous animals. They usually have protease inhibitory activity or potassium channel blocking activity, which by virtue of the effects on predator animals are essential for the survival of venomous animals. However, no Kunitz-type peptides from scorpion venom have been(More)
UNLABELLED The scorpion family Chaerilidae is phylogenetically differentiated from Buthidae. Their venom components are not known, and the evolution of the venom components is not well understood. Here, we performed a transcriptome analysis of the venom glands from two scorpion species, Chaerilus tricostatus and Chaerilus tryznai. Fourteen types of venom(More)

Scorpion has an innovative venom gland, which is an important determinant in contributing to its successful survival for more than 400 million years. Scorpion venom contains a diversity of bioactive peptides, which represent a tremendous hitherto unexplored resource for use in drug design and development. Here, StCT1, a new antimicrobial peptide gene, was(More)
