Heightened olfactory dysfunction and oral irritation among chronic smokers and heightened propylthiouracil (PROP) bitterness among menthol smokers.

Chronic cigarette smoking may influence chemosensory function, which in turn, may affect cigarette usage. Because menthol in cigarettes can attenuate nicotine bitterness, choice of menthol/nonmenthol cigarettes may be influenced by ability to perceive bitterness. We examined chemosensory function of chronic smokers, hypothesizing they would show altered function in comparison to non-smokers and by menthol cigarette preference. In laboratory-based measures, chronic smokers (N = 135; 84 menthol smokers) s...

Individual variation in PROP status, fungiform papillae density and responsiveness to taste stimuli in a large population sample.

Despite considerable research investigating the role of PROP bitterness perception and variation of fungiform papillae density (FPD) in food perception, this relationship remains controversial as well as the association between the two phenotypes. Data from 1119 subjects (38.6% male; 18-60 years) enrolled in the Italian Taste project were analysed. Responsiveness to the bitterness of PROP was assessed on the general Labelled Magnitude Scale. FPD was determined from manual counting on digital images of the t...

Can the choice of diet undermine the potential genetic risk of AT1R 1166A>C gene polymorphism?

Angiotensin II type 1 receptor (AT1R) gene 1166A>C polymorphism is strongly associated with the incidence of cardiovascular diseases and predicts the development of metabolic syndrome (MetS). There is little information about the gene-diet interactions associated with MetS. This investigation examined the interaction between dietary patterns and AT1R polymorphism in relation to development risk of MetS.

Rats can predict aversiveness of Active Pharmaceutical Ingredients.

Taste is crucial for patient acceptability and compliance with prescribed medicines, in particular with pediatric patients. Evaluating the taste of new active pharmaceutical ingredients (APIs) is therefore essential to put in place adequate taste-masking techniques, if needed, which will lead to acceptable palatable formulations. Thus, there is an urgent need to develop and optimize taste assessment methods that could be used at different stages of the drug development process. The aim of this study was to ...

The methylenetetrahydrofolate reductase genotype 677CT and non-alcoholic fatty liver disease have a synergistic effect on the increasing homocysteine levels in subjects from Chongqing, China.

The methylenetetrahydrofolate reductase (MTHFR) genotypes 677CT and 677TT are associated with elevated serum homocysteine (Hcy) levels by means of lowering the activity of MTHFR, and the increase in serum Hcy may be linked to increased susceptibility to non-alcoholic fatty liver disease (NAFLD). However, there are contradictory reports of the relationship among the MTHFR 677CT gene polymorphism, Hcy, and NAFLD. Therefore, the aim of this study was to identify potential associations and interactions of eithe...

DNA-mediated self-assembly of taste cells and neurons for taste signal transmission.

Cells can communicate with one another through physical connections and chemical signaling, activating various signaling pathways that can affect cellular functions and behaviors. In taste buds, taste cells transmit taste information to neurons via paracrine signaling. However, no previous studies have reported the in vitro co-culture of taste and neuronal cells, which allows us to monitor intercellular communications and better understand the mechanism of taste perception. Here, we introduce the first inve...

Genetic polymorphism of Methylenetetrahydrofolate reductase is associated with insulin resistance in Egyptian women with polycystic ovary syndrome.

A common polymorphism (677C to T; Ala to Val) in the methylenetetrahydrofolate reductase (MTHFR) gene is associated with decreased specific MTHFR activity and elevation of the homocysteine.

A novel SNP of PLAG1 gene and its association with growth traits in Chinese cattle.

Genetic polymorphism has great influences on the improvement of cattle traits. The polymorphism of the same gene family will greatly change the growth traits of cattle, such as the pleomorphic adenoma gene (PLAG) family. Many studies have shown that the PLAG family proteins are the transcription regulators of nuclear protein, which mainly regulates the expression of many important genes in the body. In cattle, single nucleotide polymorphisms (SNPs) within or near the PLAG1 gene is associated with economic t...

Taste Exam: A Brief and Validated Test.

The emerging importance of taste in medicine and biomedical research, and new knowledge about its genetic underpinnings, has motivated us to supplement classic taste-testing methods in two ways. First, we explain how to do a brief assessment of the mouth, including the tongue, to ensure that taste papillae are present and to note evidence of relevant disease. Second, we draw on genetics to validate taste test data by comparing reports of perceived bitterness intensity and inborn receptor genotypes. Discorda...

Development and homeostasis of taste buds in mammals.

Taste is mediated by multicellular taste buds distributed throughout the oral and pharyngeal cavities. The taste buds can detect five basic tastes: sour, sweet, bitter, salty and umami, allowing mammals to select nutritious foods and avoid the ingestion of toxic and rotten foods. Once developed, the taste buds undergo continuous renewal throughout the adult life. In the past decade, significant progress has been achived in delineating the cellular and molecular mechanisms governing taste buds development an...

Serotonin transporter gene linked polymorphism (5-HTTLPR) determines progredience of alcohol dependence in Belarusian young males.

Allelic duality and functional impact of degenerate repeat at 5'- flanking promoter region in SLC6A4 gene of the serotonin transporter (5-HTTLPR), have been in the focus of investigations over the years. Various outcomes regarding an association of its polymorphism with risks of alcohol dependence syndrome (ADS) were presented. Such studies have not been conducted in the Eastern European population e.g. Belarus. We therefore checked: the association of 5-HTTLPR polymorphism with ADS, and functional impact o...

Characterization and phylogeny of bitter taste receptor genes (Tas2r) in Squamata.

The perception of bitter taste is linked to the detection of toxins. Therefore, it facilitates avoiding the consumption of potential toxins in the diet. At the molecular level, bitter taste is mediated by taste 2 receptors (Tas2rs). Studies on Tas2r have made major advances in recent years. However, little is known about Tas2rs in Squamata, the second largest order of extant vertebrates. To explore the repertoire and phylogenetic relationships among Tas2r genes in Squamata, we identified and characterized T...

Structural and energetic basis for novel epicatechin derivatives acting as GPER agonists through the MMGBSA method.

(-)-Epicatechin (Epi) has been demonstrated to activate pathways involved in GPER-stimulated nitric oxide (NO) production via endothelial NO synthase, known as the eNOS/NO pathway. Previous studies combining synthesis of four Epi derivatives demonstrated that Epi and Epi-prop, Epi-4-prop and Epi-5-prop were able to bind GPER by acting as GPER agonists, whereas docking studies allowed observation of structural details of the binding of these derivatives at the GPER binding site. However, due to the nature of...

Experience-dependent c-Fos expression in the primary chemosensory cortices of the rat.

Eating a new food is a unique event that guides future food choices. A key element for these choices is the perception of flavor (odor-taste associations), a multisensory process dependent upon taste and smell. The two primary cortical areas for taste and smell, gustatory cortex and piriform cortex, are thought to be crucial regions for processing and responding to odor-taste mixtures. To determine how previous experience impacts the primary chemosensory cortices, we compared the expression of the immediate...

A novel polymorphism in the fatty acid desaturase 2 gene (Fads2): A possible role in the basal metabolic rate.

Fatty acyl composition of cell membrane lipids, particularly the abundance of highly unsaturated docosahexaenoic fatty acid (22:6n-3, DHA), is likely to be an important predictor of basal metabolic rate (BMR). Our study was performed using two lines of laboratory mice divergently selected for either high or low BMR. We describe a novel single nucleotide polymorphism in the Fads2 gene encoding Δ6-desaturase, a key enzyme in the metabolic pathways of polyunsaturated fatty acids (PUFAs). The allele frequencie...
