Project description:Teeth are a well-known source of information for paleoanthropologists. Here, we established the ancient dental metaproteomes in several samples from historic sites. The shotgun metaproteomics analysis relies on a iterative search strategy for the identification of the proteins and their origins.

Project description:Amelogenin, a protein involved in the formation of enamel occurs as two isoforms, AMEL X and AMEL Y, which are encoded on the X and Y chromosome respectively. Isoform-specific peptides can be used for the determination of the chromosomal sex in ancient teeth. This strategy was used to determine the chromosomal sex of individuals from tooth material of historic New Zealand cemetery samples by mass spectrometry-based amelogenin peptide analysis. We show what can happen when osteobiographies are constructed for individuals for whom osteological sex estimation was inaccurate. We also highlight the uses of peptide analysis in identifying individuals, particularly non-adults for whom osteological sex estimation is not possible. Peptide analysis of historic New Zealand cemetery samples has helped to change our interpretations and added to our understanding of these populations.

Project description:Dietary fat is rapidly deposited in skin resulting in change in skin thermal properties. Skin was found to be the largest target of deposition of dietary fat. Lipidomic analysis was performed on skin, white adipose tissue, serum, and hair.

Project description:Neuropteran larvae are fierce predators that use venom to feed on arthropods, but their venom system is poorly understood. The iconic antlions (Myrmeleontidae) are adapted to dry, sandy habitats, where they use pitfall traps and venom to catch and subdue large arthropod prey. The aphid lions, larvae of green lacewings (Chrysopidae) primarily hunt for smaller prey, such as aphids. Here, we investigate the tissue origin, composition and ecological role of venom in the European antlion Euroleon nostras and the green lacewing Chrysoperla carnea. We show that E. nostras venom has potent insecticidal activity, indicating its importance for efficient immobilization of large prey. C. carnea venom exerted no toxic effects, reflecting their specialization to small, non-defensive prey. Histological and proteotranscriptomic analysis revealed that antlion venom is produced in three distinct glands that secrete different proteins, indicating a functional compartmentalization of venom compounds. The venom system of E. nostras contains no bacteria, providing strong evidence that all venom compounds are of insect origin and not produced by bacterial symbionts as previously suggested. Our study provides a detailed analysis of the neuropteran venom system and new insights into venom biochemistry and function that may underpin the adaptation of antlions to their unique ecological niche.

Project description:Mouse hair follicles undergo synchronized cycles. Cyclical regeneration and hair growth is fueled by stem cells (SCs). During the rest phase, the HF-SCs remain quiescent due to extrinsic inhibitory signals within the niche. As activating cues accumulate, HF-SCs become activated, proliferate, and grows downward to form transient-amplifying matrix progenitor cells. We used ChIP-seq to reveal the genome-wide maps of histone modifications underlying the states of hair follicle stem cells and their transient-amplifying progeny before differentiation. Quiescent hair follicle stem cells (qHF-SCs), activated hair follicle stem cells (aHF-SCs) and transient-amplifying matrix cells (HF-TACs) were FACS-purified for ChIP-sequcencing.

Project description:Marine cone snails have attracted researchers from all disciplines but early life stages have received limited attention due to difficulties accessing or rearing juvenile specimens. Here, we document the culture of Conus magus from eggs through metamorphosis to reveal dramatic shifts in predatory feeding behaviour between post-metamorphic juveniles and adult specimens. Adult C. magus capture fish using a set of paralytic venom peptides combined with a hooked radular tooth used to tether envenomed fish. In contrast, early juveniles feed exclusively on polychaete worms using a unique “sting-and-stalk” foraging behaviour facilitated by short, unbarbed radular teeth and a distinct venom repertoire that induces hypoactivity in prey. Our results demonstrate how coordinated morphological, behavioural and molecular changes facilitate the shift from worm- to fish-hunting in C. magus, and showcase juvenile cone snails as a rich and unexplored source of novel venom peptides for ecological, evolutionary and biodiscovery studies.

Project description:Dental calculus is becoming a crucial material in the study of past populations, with increasing interest in its proteomic and genomic content. Here we suggest further development of protocol for analysis of ancient proteins and a combined approach for subsequent ancient DNA extraction. We tested the protocol on recent teeth. We then applied the optimised protocol to ancient teeth to limit the destruction of calculus, as it is a precious and irreplaceable source of dietary, microbiological, and ecological information in the archaeological context. Finally, the applicability of the protocol was proven on samples of ancient calculus.

Project description:Bdellovibrio bacteriovorus is a Gram-negative bacterium that is a pathogen of other Gram-negative bacteria, including many bacteria which are pathogens of humans, animals and plants. As such Bdellovibrio has potential as a biocontrol agent, or living antibiotic. B. bacteriovorus HD100 has a large genome and it is not yet known which of it encodes the molecular machinery and genetic control of predatory processes. We have tried to fill this knowledge-gap using mixtures of predator and prey mRNAs to monitor changes in Bdellovibrio gene expression at a timepoint of early-stage prey infection and prey killing in comparison to control cultures of predator and prey alone and also in comparison to Bdellovibrio growing axenically (in a prey-or host independent “HI” manner) on artificial media containing peptone and tryptone. From this we have highlighted genes of the early predatosome with predicted roles in prey killing and digestion and have gained insights into possible regulatory mechanisms as Bdellovibrio enter and establish within the prey bdelloplast. Approximately seven percent of all Bdellovibrio genes were significantly up-regulated at 30 minutes of infection- but not in HI growth- implicating the role of these genes in prey digestion. Five percent were down-regulated significantly, implicating their role in free-swimming, attack-phase physiology. This study gives the first post- genomic insight into the predatory process and reveals some of the important genes that Bdellovibrio expresses inside the prey bacterium during the initial attack.
