We explored genetic influences on the perception of taste and smell stimuli. Adult twins rated the chemosensory aspects of water, sucrose, sodium chloride, citric acid, ethanol, quinine hydrochloride, phenylthiocarbamide (PTC), potassium chloride, calcium chloride, cinnamon, androstenone, Galaxolide™, cilantro, and basil. For most traits, individual differences were stable over time and some tr...
SETO. Taste sensitivity in various strains of mice. Am. J. Physiol. 202 (6) : I 200-1204. 1g62.-The present study was designed to elucidate the differences in taste sensitivity in various strains of mice, and to study the relationship between taste sensitivity and color of the fur. Taste thresholds for four kinds of taste substance, i.e., sodium chloride, saccharine, acetic acid, and phenylthio...
Although human bitter taste perception is hypothesized to be a dietary adaptation, little is known about genetic signatures of selection and patterns of bitter taste perception variability in ethnically diverse populations with different diets, particularly from Africa. To better understand the genetic basis and evolutionary history of bitter taste sensitivity, we sequenced a 2,975 bp region en...
G-protein-coupled receptors signaling bitter taste (T2Rs) in the oral gustatory system and the alpha-subunit of the taste-specific G-protein gustducin are expressed in the gastrointestinal (GI) tract. alpha-Subunit of the taste-specific G-protein gustducin colocalizes with markers of enteroendocrine cells in human and mouse GI mucosa, including peptide YY. Activation of T2Rs increases cholecyst...
BACKGROUND/AIMS Bitter taste receptors are expressed throughout the digestive tract. Data on animals have suggested these receptors are involved in the gut hormone release, but no data are available in humans. Our aim is to assess whether bitter agonists influence food intake and gut hormone release in healthy subjects. METHODS Twenty healthy volunteers were enrolled in a double-blind cross-o...
The people have different behaviour to choose the food, and there are many factors that affect the food choices. The best significant factor to choose the food is taste. Differences in taste perception of several taste modalities are associated to difference in the taste receptors. Polymorphisms of the genes that encoding these taste receptors may clarify this unpredictability in taste percepti...
BACKGROUND A novel family of G protein-coupled receptors, TAS2Rs, has recently been characterized and linked to sensitivity to bitter taste compounds. We have previously reported that a missense mutation in the TAS2R16 gene reduces the sensitivity of the receptor to bitter-taste stimuli and that it is associated with risk for alcohol dependence. Other family-based studies on the genetic transmi...
