Major urinary proteins (MUPs) in the urine of male house mice, Mus domesticus, bind the male signalling volatiles 2- sec -butyl-4,5-dihydrothiazole (thiazole) and 3,4-dehydro- exo -brevicomin (brevicomin) and slowly release these volatiles from urinary scent marks. To examine the role of urinary proteins and volatiles, either attached or unattached to the proteins, in competitive scent marking, we fractionated urine from isolated male BALB/c laboratory mice, Mus musculus, by size-exclusion…

Pheromones that correlate with reproductive success in competitive conditions

Novel evidence for chemical signals that correlate with male reproductive success of house mice living in competitive conditions is provided, which raises caveats for conventional laboratory studies.

Rodent Urinary Proteins: Genetic Identity Signals and Pheromones

Comparative studies of other rodents are starting to reveal considerable diversity in concentration, sexual ­dimorphism and polymorphic complexity of lipocalins in scent signals; these differences are likely to reflect species-specific requirements for recognition and ­assessment through scent.

The interaction between the chemical basis of mouse scents and the dynamics of their competitive scent marking behaviour is reviewed, demonstrating how it is possible to provide reliable signals of the competitive ability and identity of individual males.

Searching for Major Urinary Proteins (MUPs) as Chemosignals in Urine of Subterranean Rodents

Evidence that rodent species can successfully transmit and receive chemosignals without the necessity of MUPs is extended, to subterranean rodents.

Regulation of Sexually Dimorphic Expression of Major Urinary Proteins

A phylogenetic analysis on the origins of male-biased MUP gene expression in Mus musculus suggests that this sexual dimorphism evolved by increasing male MUP expression rather than reducing female expression.

Skin-derived semiochemicals of the lacertid lizard Acanthodactylus boskianus

While the compounds characterizing skin slough are qualitatively similar to femoral secretions, they could represent an adaptation to hot and dry habitats of A. boskianus, there is not enough evidence to support their possible role as chemosignals, and behavioral experiments should be performed to test the possible use of skin shedding in intraspecific communication.

Muscular hypertrophy of urinary bladders in dominant tilapia facilitates the control of aggression through urinary signals

The results suggest that the larger, more muscular bladder of dominant males is an adaptation, facilitating higher urination frequency, post-renal modulation and storage of larger urine volumes for longer.

Monitoring potential semiochemicals in individual mouse urine samples

This work validates a method for detecting potential semiochemicals in mouse urine samples with a volume as small as 10 μL and highlights the usefulness of the proposed analytical method for research in this area.



Proteins in urine scent marks of male house mice extend the longevity of olfactory signals

The nature of their response suggests that, from a distance, mice may be unable to tell whether airborne signals emanate from scent marks or from the donor himself and it is suggested that this may provide territory owners with a major advantage in defending their territories.

Urinary chemical cues affect light avoidance behaviour in male laboratory mice,Mus musculus

Mice can use the information carried by the odorant molecules released by MUPs to recognize the urine of male mice, and respond appropriately, in the presence or absence of male urinary substances.

Volatile signals of the major histocompatibility complex in male mouse urine.

Results supporting the hypothesis that the MHC-determined urinary odor is composed of a mixture of volatile carboxylic acids occurring in relative concentrations that are characteristic of the odortype are reported.

Socio-sexual olfactory preference in female mice: Attractiveness of synthetic chemosignals

Quantitative chromatographic profiling of odours associated with dominance in male laboratory mice

The results demonstrate that murine semiochemicals are accessible to quantitative analysis at the level of the individual and also demonstrate that aggressive initiator ranks and encounter winner ranks are compatible with each other.

Vomeronasal/accessory olfactory system and pheromonal recognition.

Since large quantities of the polymorphic major urinary proteins from the lipocalin family found in urine serve as transporters for the dihydrothiazoles and brevicomins, and differ across strains, then these proteins must participate in pheromone recognition in the context of pregnancy block.

Selective Activation of G Protein Subtypes in the Vomeronasal Organ upon Stimulation with Urine-derived Compounds*

Results provide the first experimental evidence that V1Rs coexpressed with Gimay be activated by lipophilic probably volatile odorants, whereas V2Rs co Expressed with Go seem to be specialized to interact with pheromonal components of proteinaceous nature.
