Interaction of Skatole and Androstenone in the Olfactory Perception of Boar Taint [PDF]

Journal of Agricultural and Food Chemistry, 2016
This study analyzed odor-odor interactions of two malodorous volatile substances, androstenone and skatole, that may accumulate in fat and meat of uncastrated male (boar) pigs. Therefore, fat samples were collected from 1000+ entire male pig carcasses for sensory evaluation and quantification of boar taint compounds using gas chromatography-mass ...

Impact of Androstenone on Leash Pulling and Jumping Up in Dogs [PDF]

Animals, 2016
Dogs are relinquished to shelters due to behavioral problems, such as leash pulling and jumping up. Interomones are chemical cues produced by one species that elicit a response in a different species.

Genetic Admixture and Flavor Preferences: Androstenone Sensitivity in Malagasy Populations [PDF]

Human Biology, 2015
The genetic basis of androstenone anosmia has been well studied due to androstenone's putative role as a human sex pheromone and its presence in pork meat. Polymorphisms have been identified on the olfactory receptor gene OR7D4, which significantly affect perception of androstenone pleasantness and intensity in several Western populations.

Hepatic Gene Expression and Metabolite Profiles of Androstenone and Skatole Relative to Plasma Estrone Sulfate Levels in Boars [PDF]

Biomolecules
Testicular steroids can alter the activity and expression of enzymes within the liver and may influence the metabolism of skatole and androstenone, which are responsible for boar taint.

Gene expression profiles in testis of pigs with extreme high and low levels of androstenone [PDF]

BMC Genomics, 2007
Background: Boar taint is a major obstacle when using uncastrated male pigs for swine production. One of the main compounds causing this taint is androstenone, a pheromone produced in porcine testis.

INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence. [PDF]

Andrology
ABSTRACT Background Study aimed to obtain insights into physiological responses to immunocastration in pubertal boars by evaluating effects of alternative vaccination protocols and identifying a reliable immunocastration biomarker. Objectives It was hypothesized that the timing of gonadotropin‐releasing hormone (GnRH) suppression by immunocastration ...

Antimelanoma activities of chimeric thiazole–androstenone derivatives [PDF]

Royal Society Open Science, 2021
The discovery of chimeric anti-melanoma agents is reported. These molecules are potent growth suppressors of melanoma cells in vitro with growth inhibition of 50% (GI 50 ) values as low as 1.32 µM. Compounds were more toxic to melanoma cells in vitro than commonly used

The Prevalence of Androstenone Anosmia [PDF]

Chemical Senses, 2003
It has been estimated that approximately 30% of the population is unable to detect the odor of androstenone. These estimates, however, were made using tests and criteria optimized for identifying detection. Such criteria favor Type II over Type I errors--that is, they are excellent at identifying true detectors at the cost of erroneously labeling some ...

Optimizing Odorants for Olfactory Training Based on Olfactory Receptor-Ligand Pair Analysis. [PDF]

Laryngoscope
This study employs receptor–ligand interaction analysis and olfactory epithelium transcriptomics to optimize olfactory training (OT). A novel four‐odorant combination (galaxolide, eugenol acetate, [−]‐menthol, geranyl acetate) activates 83.9% of 385 human olfactory receptors (ORs), covering 69.9% of estimated OR expression—significantly outperforming ...

Discovery of 16-Androstenes (Androstenone and Androstenol), Their Synthesis Pathway, and Possible Role in Reproduction of Mouse Deer (Moschiola indica)

Cells, 2022
We discovered odorous 16-androstenes (Androstenone and Androstenol) in endangered mouse deer during a captive breeding program. This study examined the molecular characteristics, their synthesis pathway, and the possible functional role of these ...
