Genotyping (Taqman qPCR assays) was performed on DNA extracted from blood samples (n = 563) from an elderly cohort. Homozygosity for the minor allele of all polymorphisms was significantly associated with a lower BMI in males. The TAS2R4-rs2233998 CC genotype, the TAS2R4-rs2234001 CC genotype and the TAS2R5-rs2227264 TT genotype were associated with lower BMI (2.1, 2.1 and 2.2 units; p = 0.002, 0.003 and 0.001, respectively). Epicatechin intake was not associated with BMI and genotype was not associated with epicatechin intake. This suggests that the association between TAS2R genotype and elevated BMI risk occurs through altered extra-oral responses and not directly via altered epicatechin intake.]]> Wed 26 Oct 2022 10:43:50 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48438 Wed 26 Jul 2023 09:49:58 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37585 Wed 19 Jan 2022 15:19:31 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33649 Wed 19 Jan 2022 15:16:53 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38672 Wed 15 Dec 2021 14:39:24 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52623 Wed 13 Mar 2024 13:53:59 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37683 n = 536) was conducted to explore relationships between the salt taste-related SNP TRPV1-rs8065080 (assessed by Taqman genotyping assay), dietary habits and biomarkers of health. Data were analysed with standard least squares regression modelling and Tukey's HSD post hoc tests. No association was found between the TRPV1-rs8065080 genotype, sodium intake or multiple diet quality indices (assessed by food frequency questionnaire). Sodium-related markers of health including blood pressure and markers of kidney function (urinary creatinine and albumin/creatinine ratio) and general health markers, such as Body Mass Index (BMI), were also not related to TRPV1-rs8065080 genotype. To date, this study is the most comprehensive investigation conducted to determine if the TRPV1-rs8065080 genotype relates to sodium intake and health markers influenced by sodium intake. Although no significant relationships were found, these findings are an important contribution to the limited body of knowledge surround this SNP. In addition to further research across other ages and cultures, the TRPV1-rs8065080 genotype may interact with other ion channels, and so further studies are required to determine if polymorphic variations influence sodium intake, diet and health.]]> Wed 02 Mar 2022 14:24:15 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49012 Wed 01 May 2024 15:54:23 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45310 Thu 27 Oct 2022 13:56:22 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42951 KCNJ2 gene involved in the transduction of sour taste have been linked to variations in sour taste and non-gustatory functions. However, relationships between sour taste genetics, mild cognitive impairment, and diet quality are yet to be elucidated. This study investigated the associations between the presence of the KCNJ2-rs236514 variant (A) allele, diet quality indices, and mild cognitive impairment evaluated by the Mini-Mental State Examination (MMSE), in a secondary cross-sectional analysis of data from the Retirement Health & Lifestyle Study. Data from 524 elderly Australians (≥65y) were analyzed, using standard least squares regression and nominal logistic regression modeling, with demographic adjustments applied. Results showed that the presence of the KCNJ2-A allele is associated with increased proportions of participants scoring in the range indicative of mild or more severe cognitive impairment (MMSE score of ≤26) in the total cohort, and males. These associations remained statistically significant after adjusting for age, sex, and diet quality indices. The absence of association between the KCNJ2-A allele and cognitive impairment in women may be related to their higher diet quality scores in all indices. The potential link between sour taste genotype and cognitive impairment scores may be due to both oral and extra-oral functions of sour taste receptors. Further studies are required on the role and relationship of neurotransmitters, sour taste genotypes and sour taste receptors in the brain, and dietary implications, to identify potential risk groups or avenues for therapeutic or prophylactic interventions.]]> Thu 08 Sep 2022 14:04:41 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41872 Mon 15 Aug 2022 10:03:25 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52654 Fri 20 Oct 2023 08:55:23 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37726 Fri 03 Dec 2021 10:33:48 AEDT ]]>
