A genome-wide association study on androstenone levels in pigs reveals a cluster of candidate genes on chromosome 6 [PDF]

BMC Genetics, 2010
Background In many countries, male piglets are castrated shortly after birth because a proportion of un-castrated male pigs produce meat with an unpleasant flavour and odour. Main compounds of boar taint are androstenone and skatole. The aim of this high-

Genetic variation of an odorant receptor OR7D4 and sensory perception of cooked meat containing androstenone. [PDF]

PLoS ONE, 2012
Although odour perception impacts food preferences, the effect of genotypic variation of odorant receptors (ORs) on the sensory perception of food is unclear.

The Effects of Androstenone on the Plasma Serotonin, β-Endorphin, and Cortisol Concentrations in Thoroughbred Horses

Animals, 2021
Androstenone influences the changing behaviors of animals. Previous studies discovered that an androstenone receptor was expressed in horses and treatment with androstenone induced horses to be more compliant.

The results of meat quality traits and sensory characteristics according to the concentration of androstenone in uncastrated pigs [PDF]

Journal of Animal Science and Technology
Pork quality is determined by several attributes, among which odor and taste are the utmost significant. Therefore, this study was aimed to assess the effects of boar odor hormone concentration on the quality traits and sensory acceptability of pork.

Effects of <i>CYP2E1</i> Polymorphism and Dietary Supplementation With Jerusalem Artichoke on Skatole and Indole Levels in the Back Fat and Feces of Boars, and Liver mRNA Expression. [PDF]

Food Sci Nutr
This study investigated the combined effects of CYP2E1 gene polymorphism (SNP NM_214421.1: c.1423G > A) and short‐term dietary supplementation with Jerusalem artichoke (Helianthus tuberosus, 8.2% tuber meal) on skatole and indole concentrations in back fat and feces of 25 crossbreed boars, and on hepatic CYP2E1 mRNA expression. Animals were assigned to

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 ...

Differential Regulation of Male-Hormones-Related Enhancers Revealed by Chromatin Accessibility and Transcriptional Profiles in Pig Liver [PDF]

Biomolecules
Surgical castration can effectively avoid boar taint and improve pork quality by removing the synthesis of androstenone in the testis, thereby reducing its deposition in adipose tissue.

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.

Inter-laboratory comparison of methods to measure androstenone in pork fat

Animal, 2011
Today, different analytical methods are used by different laboratories to quantify androstenone in fat tissue. This study shows the comparison of methods used routinely in different laboratories for androstenone quantification: Time-resolved ...

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 ...
