Venom evolution of 15 neotropical ants

ABSTRACT: To comprehend the drivers underlying venom variation in ants, we selected 15 Neotropical species and recorded a range of traits, including ecology, morphology, and venom bioactivity. Principal component analysis of both morphological and venom bioactivity traits revealed that stinging ants display two functional strategies. Additionally, phylogenetic comparative analysis indicated that venom function (predatory, defensive, or both) and mandible morphology significantly correlate with venom bioactivity and amount, while pain-inducing activity trades off with insect paralysis. Further analysis of the venom biochemistry of the 15 species revealed switches between cytotoxic and neurotoxic venom compositions in some species. This study highlights the fact that ant venoms are not homogenous, and for some species, there are major shifts in venom composition associated with the diversification of venom ecological functions.

Venomics of the Milos viper (Macrovipera schweizeri)

Project description:Snakebite is a neglected tropical disease and a globally important driver of death and morbidity. Vipers of the genus Macrovipera (Viperidae: Viperinae) are among the snakes of higher medical importance in the Old World. Despite the medical relevance of Macrovipera venoms, the knowledge regarding them is heterogeneously distributed with virtually all works conducted so far focusing on subspecies of Macrovipera lebetinus, while other species within the genus are largely overlooked. Here we present the first proteomic evaluation of the venom from the Greek endemic Milos viper (Macrovipera schweizeri). In line with clinical symptoms typically elicited by Macrovipera envenomations, Milos viper venom primarily comprises coagulotoxic and cytotoxic protein families, such as metalloproteinases (svMP) and serine proteases (svSP). We conducted comparative bioactivity assays on venoms from M. schweizeri and the M. lebetinus subspecies M. lebetinus cernovi, M. lebetinus obtusa, and M. lebetinus turanica, and showed that they all exhibit similarities in levels of cytotoxicity proteolytic activity, and inhibition of prokaryotic growth. Lastly, we compared 1D-SDS-PAGE and RP-HPLC Macrovipera spp. venom profiles, as well as our proteomic data with previously published Macrovipera venom proteomes. The analyses performed reveal that a general venom profile seems to be conserved across blunt-nosed vipers, and that, similarly to M. lebetinus venom, M. schweizeri venom is able to cause significant tissue damage. The present work represents an important starting point to the development of comparative studies across the full taxonomic range of Macrovipera spp., and can potentially help optimize the treatment of envenomations caused by M. schweizeri.

Venomics of the Central-European Myrmicine Ants Myrmica rubra and Myrmica ruginodis

Project description:Animal venoms are a rich source of novel biomolecules with tremendous potential in medicine and agriculture. Ants represent one of the most species-rich lineages of venomous animals. However, only a fraction of their biodiversity has been studied so far. Here, we investigated the venom compositions from Myrmica rubra and Myrmica ruginodis, two members of the Myrmicinae subfamily of ants. We applied a proteo-transcriptomics based venomics workflow. Our analysis revealed that venoms of both species are composed of several protein classes, such as venom serine protease, cysteine-rich secretory proteins, antigen 5 and pathogenesis-related 1 proteins (CAP), Kunitz-type serine protease inhibitors or venom acid phosphatase. Several protein classes identified are known venom allergens, and for the first time we detected phospholipase A1 in the venom of M. ruginodis. We also identified two novel toxins of the epidermal growth factor (EGF) family in its venom proteome and an array of additional EGF-like toxins in venom gland transcriptomes of both species. They display similarity to known toxins from the related myrmecine Manica rubida and the Australian red bulldog ant Myrmecia gullosa of the Myrmeciinae subfamily and may serve as nociceptive weapons in defensive scenarios. Our work suggests that the venoms of M. rubra and M. ruginodis contain many high molecular proteins and enzymes with putatively cell damaging functions. Nevertheless, the presence of EGF-like toxins underpins that myrmicine ants also recruited smaller peptide components into their venom arsenal. Although little is known about the bioactivity and function of these EGF-like toxins, their presence in Myrmecinae and Myrmeciinae suggests that they play an important role for the venom systems of Formicoidea. Our work adds to the emerging picture of ant venoms as a source for novel biomolecules. This underlines the importance to incorporate such taxa in future venom bioprospecting programs.

Exaptation of an evolutionary constraint enables behavioural control over the composition of secreted venom in giant centipedes

Project description:Venoms are biochemical arsenals that have emerged in numerous animal lineages, where they have coevolved with morphological and behavioural traits for venom production and delivery. In centipedes, venom evolution is thought to be constrained by the morphological complexity of their venom glands due to physiological limitations on the number of toxins produced by their secretory cells. Here, we show that the uneven toxin expression that results from these limitations have enabled giant centipedes to regulate the composition of their secreted venom despite having morphologically undifferentiated venom glands. We show that this control is likely achieved by the complex neuronal networks that innervate each venom gland subunit and is facilitated by morphological adaptations that circumvent the physiological evolutionary constraints on venom production. Our results suggest behavioural control over venom composition may be an overlooked aspect of venom biology and provide an example of how exaptation can facilitate evolutionary innovation and novelty.

Comparative gender peptidomics of Bothrops atrox venoms: new peptides and evidences of increased disintegrins levels in the venoms of females

Project description:Background: Bothrops atrox is known to be the pitviper responsible for most snakebites and human fatalities in the Amazon region. It can be found in a wide geographical area including the northern South America, the east of Andes and the Amazon basin. Possibly due to its wide distribution range and generalist feeding, intraspecific venom variation was reported by previous proteomics studies. Sex-based and ontogenetic variations on venom compositions of Bothrops snakes were also subject of proteomic and peptidomic analysis. However, the venom peptidome of B. atrox remains unknown. Methods: we conducted a mass spectrometry-based analysis of the venom peptides of individual male and female specimens combining bottom-up and top-down approaches. Results: We identified in B. atrox a total of 105 native peptides in the mass range of 0.4 to 13.9 kDa. Quantitative analysis showed that Phospholipase A2 and Bradykinin Potentiating Peptides were the most abundant peptide families in both genders, but the disintegrins levels were significantly increased in the venoms of females. Known peptides processed at non-canonical sites and new peptides were also revealed in this work. Conclusion: The venom peptidomes of male and female specimens of B. atrox were analyzed by mass spectrometry-based approaches in this work. The study points to differences in the disintegrin levels in the venoms of females that may result in distinct pathophysiology in envenomation. Further research is needed to explore its biological implications.

Lachesis muta snake venom peptidome

Project description:Snake venoms are known to be major sources of peptides with different pharmacological properties. In this study, we comprehensively explored the venom peptidomes of three specimens of Lachesis muta, the largest venomous snake in South America, using mass spectrometry techniques. The analysis revealed 19 main chromatographic peaks common to all specimens. A total of 151 peptides were identified, including 69 from a metalloproteinase, 58 from the BPP-CNP precursor, and 24 from a L-amino acid oxidase. To our knowledge, 126 of these peptides were reported for the first time in this work, including a new SVMP-derived peptide fragment, Lm-10a. Our findings highlight the dynamic nature of toxin maturation in snake venoms, driven by proteolytic processing, post-translational modifications, and cryptide formation.

High-throughput proteomics of the 26 medically most important elapids and vipers from sub-Saharan Africa

Project description:Venomous snakes are important parts of the ecosystem, and their behavior and evolution have been shaped by their surrounding environments over the eons. This is reflected in their venoms, which are typically highly adapted for their biological niche, including their diet and defense mechanisms for deterring predators. Sub-Saharan Africa is rich in venomous snake species, of which many are dangerous to humans due to the high toxicity of their venoms and their ability to effectively deliver large amounts of venom into their victims via their bite. In this study, the venoms of 26 of sub-Saharan Africa’s medically most relevant elapid and viper species were subjected to parallelized toxicovenomics analysis. The analysis included venom proteomics and enables a robust comparison of venom profiles between species. Moreover, two new venom proteomes (N. anchietae and E. leucogaster) are presented here for the first time.

Venom proteomic analysis of two medically important Nigerian viperidae (Echis ocellatus and Bitis arietans) snake species

Project description:Hydrophilic interaction liquid chromatography coupled with LC- MS/MS was used to analyze the crude venom extracts of Echis ocellatus (Carpet viper) and Bitis arietans (Puff adder). The gel-free proteomic analysis of the crude venom extracts from E. ocellatus and B. arietans yielded the identification of 86 and 80 proteins, respectively. Seventy- nine proteins were common between the two snake species with a 90.8% similarity. The identified proteins belong to 12 protein families where serine proteases (22.31%) and metalloproteinases (21.06%) were the dominant proteins in the venom of B. arietans. Metalloproteinases (34.84%), phospholipase A 2 s (25.69%) and serine proteases (17.25%) represents the major toxins in the E. ocellatus venom. This study provides some valuable insights into the toxin families to be neutralized in case of envenomation.
