Scentmarking communication in the female rat_C4PR_LIV

ABSTRACT: Chemical communication in mammals is in part mediated through the deposition of scent marks in the environment. Volatile and non-volatile moleculesin the scent marksconvey important information about the donor animal, such as sex, social and reproductive status,and stimulatea response in the receptor animal. In rodents, most of the work about deciphering the molecular composition of scent markshas been focused on mice. In rats, by contrast, knowledge is limitedand the molecular complexity of scent marks is not as well described as in mice. In particular, the sources and roles of proteins in scent marks are largely undefined, with even less knowledge when we consider female rats. We therefore conducted a global proteomic analysis of scent marks from femalerats (Rattus norvegicus)to define the protein composition and then we investigated the role of scent marks in sexual communication. Our study revealed that protein pattern inscent marks greatly differsfrom that in naturally voided urine, indicatinga different tissue of41origin. In particular, female scent marks are dominated by lipocalins, notablymajor urinary proteins, whereas urinary output of these proteins is almost imperceptible.Further analysis revealed that the most plausible source of the components in scent marks are the clitoral glands,implying a critical role of theseaccessory glands in sexual communication in the rat.

Proteomic evaluation of urine of the female of domestic dog (Canis familiaris), during different stages of ovarian cycle

Project description:Chemical signals are essential for communication between living organisms. Dogs possess two sensory organs enabling chemical communication; the main olfactory system and the vomeronasal organ (VNO). Besides, contact chemoreception is also pertinent, by which non-volatile molecules, including but not limited to proteins, are recognized as chemical signals. However, non-volatile chemical signals have been sparsely studied in dogs. Therefore, we aimed to examine the urinary proteins of female domestic dogs during estrus and anestrus phases to detect and identify such non-volatile chemical signals.

Identification of potential chemical signals in the European water vole Arvicola terrestris

Project description:The water vole Arvicola terrestris (= Arvicola amphibious L.) is endemic in Europe where its outbreak generates severe economic losses for farmers. Our project aimed at deciphering the modalities of chemical communication in this species, to develop new sustainable methods for populations control. The water vole, as well as other rodents, uses specific urination sites as territorial and sex pheromone markers, the chemical and biochemical identification of which is still unknown. Lateral scent glands and urine samples were collected from wild males and females caught in the field, at different periods of the year. Volatile signals were searched in urine by SPME/GC-MS, and in lateral scent glands by solvent extraction followed by GC-MS. The volatile composition of urine was analysed for each individual and not on pooled samples, showing no significant difference between males and females. Lateral scent glands contained some volatile components (pyrazines, alcohols, terpenes), and mostly long chain fatty acid esters, again without quantitative and qualitative differences between sexes. Conversely, the urinary protein content, analysed by 1D- and 2D-electrophoresis is different, as only males secrete high levels of lipocalins, whatever the reproduction period. The proteins were identified by mass spectrometry and “de novo” analysis (Orbitrap), which provided specific information to design primers for PCR amplification of cDNA sequences. Thus, urinary proteins were characterized by direct amplification from liver RNA. The identified protein sequences are closed to those of Myodes glareolus, a closely related species of Cricetidae, and to hamster Aphrodisin.

Drosophila female reproductive glands contribute to mating plug composition and the timing of sperm ejection

Project description:Reproductive traits that influence female remating and competitive fertilization rapidly evolve in response to sexual selection and sexual conflict. One such trait, observed across diverse animal taxa, is the formation of a structural plug inside the female reproductive tract, either during or shortly after mating. In Drosophila melanogaster, male seminal fluid forms a mating plug inside the female bursa, which has been demonstrated to influence sperm entry into storage and latency of female remating. Processing of the plug, including its eventual ejection from the female's reproductive tract, influences the competitive fertilization success of her mates and is mediated by female × male genotypic interactions. However, female contributions to plug formation and processing have received limited attention. Using developmental mutants that lack glandular female reproductive tract tissues, we reveal that these glandular tissues are essential for the mating plug to be ejected. We further use proteomics to demonstrate that female glandular proteins, and especially proteolytic enzymes, contribute to mating plug composition and that the absence of glands has a widespread impact of plug formation and composition. Together, these phenotypic and molecular data resolve molecular mechanisms of important postmating, intersexual interactions and cryptic female choice.

Molecular characterization of firefly nuptial gifts: a multi-omics approach sheds light on postcopulatory sexual selection

Project description:Postcopulatory sexual selection is recognized as a key driver of reproductive trait evolution, including the machinery required to produce endogenous nuptial gifts. Despite the importance of such gifts, the molecular composition of the non-gametic components of male ejaculates and their interactions with female reproductive tracts remain poorly understood. During mating, male Photinus fireflies transfer to females a spermatophore gift manufactured by multiple reproductive glands. Here we combined transcriptomics of both male and female reproductive glands with proteomics and metabolomics to better understand the synthesis, composition and fate of the spermatophore in the common Eastern firefly, Photinus pyralis. Our transcriptome of male glands revealed up-regulation of proteases that may enhance male fertilization success and activate female immune response. Using bottom-up proteomics we identified 208 functionally annotated proteins that males transfer to the female in their spermatophore. Targeted metabolomic analysis also provided the first evidence that Photinus nuptial gifts contain lucibufagin, a firefly defensive toxin. The reproductive tracts of female fireflies showed increased gene expression for several proteases that may be involved in egg production. This study offers new insights into the molecular composition of male spermatophores, and extends our understanding of how nuptial gifts may mediate postcopulatory interactions between the sexes.

Single-Cell Atlas of a Rat Model of Vaginal Birth Injury induced Stress Urinary Incontinence

Project description:Stress urinary incontinence (SUI) greatly affects the daily life of numerous women and is closely related to a history of vaginal delivery and aging. We used vaginal balloon dilation to simulate vaginal birth injury in young and middle-aged rats to produce a SUI animal model, and found that young rats restored urethral structure and function well, but not the middle-aged rats. To identify the characteristics of cellular and molecular changes in the urethral microenvironment during the repair process of SUI. We profiled 51,690 individual female rat urethra cells from 24 and 48 weeks old, with or without simulated vaginal birth injury.

Proteomics of Galápagos marine iguanas links function of femoral gland proteins to the immune system

Project description:Communication between individuals via molecules, termed chemosignaling, is widespread among animal and plant species. However, we lack knowledge on the specific functions of the substances involved for most of such systems. The femoral gland is an organ secreting a waxy substance, which is involved in chemical communication in lizards. While the lipids and volatile substances secreted by the femoral glands have been investigated in several biochemical studies, the protein composition and functions of secretions are completely unknown. Applying a proteomic approach, we provide the first attempt to comprehensively characterize the protein composition of femoral gland secretions from the Galápagos marine iguana. Using samples from several organs, the marine iguana proteome was assembled by next generation sequencing and mass spectrometry, resulting in 7,513 proteins; 4305 proteins were present in the femoral gland, including keratins, small serum proteins and fatty acid-binding proteins. Surprisingly, no proteins with obvious roles in partner recognition or inter-species communication could be identified. However, we found several proteins with direct associations to the innate immune system, such as lysozyme C, antileukoproteinase (ALP), pulmonary surfactant protein (SFTPD) and galectin (LGALS1), suggesting the femoral glands function as an important barrier to infection. The identification of previously unrecognized effective anti-microbial peptides from the femoral gland show similar activities against E.coli and B. subtilis compared to oncocin. This proteomics dataset is a valuable resource for future functional protein analysis and demonstrates that femoral glands secretions covers also functions of the innate immune system.

The major urinary protein gene cluster knockout mouse as a novel model for translational metabolism research [RRBS]

Project description:Scientific evidence suggests that not only murine scent communication is regulated by major urinary proteins, but that their expression may also vary in response to metabolism via a yet unknown mechanism. Major urinary proteins are expressed mainly in the liver, showing a sexually dimorphic pattern with substantially higher expression in males. Here, we investigate the metabolic implications of a major urinary protein knockout in twelve-week-old male and female C57BL/6N mice during ad libitum feeding. Despite both sexes of major urinary protein knockout mice displayed numerically increased body weight and visceral adipose tissue proportions compared to sex-matched wildtype mice, the main genotype-specific metabolic differences were observed exclusively in males. Male major urinary protein knockout mice exhibited plasma and hepatic lipid accumulation accompanied by a hepatic transcriptome indicating an activation of lipogenesis. These findings match the higher major urinary protein expression in male compared to female wildtype mice, suggesting a more distinct reduction in energy requirements in male compared to female major urinary protein knockout mice. The observed sex-specific anabolic phenotype confirms a role of major urinary protein in metabolism and, since major urinary proteins are not expressed in humans, suggests the major urinary protein knockout mouse as a potential alternative model for translational metabolism research which needs to be further elucidated.
