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 ]]> JMJD6 is a tumorigenic factor and therapeutic target in neuroblastoma https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45069 JMJD6 gene at 17q21-ter activates gene transcription. Here we show that JMJD6 forms protein complexes with N-Myc and BRD4, and is important for E2F2, N-Myc and c-Myc transcription. Knocking down JMJD6 reduces neuroblastoma cell proliferation and survival in vitro and tumor progression in mice, and high levels of JMJD6 expression in human neuroblastoma tissues independently predict poor patient prognosis. In addition, JMJD6 gene is associated with transcriptional super-enhancers. Combination therapy with the CDK7/super-enhancer inhibitor THZ1 and the histone deacetylase inhibitor panobinostat synergistically reduces JMJD6, E2F2, N-Myc, c-Myc expression, induces apoptosis in vitro and leads to neuroblastoma tumor regression in mice, which are significantly reversed by forced JMJD6 over-expression. Our findings therefore identify JMJD6 as a neuroblastoma tumorigenesis factor, and the combination therapy as a treatment strategy.]]> Thu 27 Oct 2022 14:03:24 AEDT ]]> Functional and Clinical Studies Reveal Pathophysiological Complexity of CLCN4-Related Neurodevelopmental Condition https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50492 Thu 27 Jul 2023 09:53:32 AEST ]]> LncRNA REG1CP promotes tumorigenesis through an enhancer complex to recruit FANCJ helicase for REG3A transcription https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37758 regenerating islet-derived (REG) gene family are important regulators of many cellular processes. Here we functionally characterise a non-protein coding product of the family, the long noncoding RNA (lncRNA) REG1CP that is transcribed from a DNA fragment at the family locus previously thought to be a pseudogene. REG1CP forms an RNA–DNA triplex with a homopurine stretch at the distal promoter of the REG3A gene, through which the DNA helicase FANCJ is tethered to the core promoter of REG3A where it unwinds double stranded DNA and facilitates a permissive state for glucocorticoid receptor α (GRα)-mediated REG3A transcription. As such, REG1CP promotes cancer cell proliferation and tumorigenicity and its upregulation is associated with poor outcome of patients. REG1CP is also transcriptionally inducible by GRα, indicative of feedforward regulation. These results reveal the function and regulation of REG1CP and suggest that REG1CP may constitute a target for cancer treatment.]]> Thu 27 Jan 2022 15:55:02 AEDT ]]> Mild phenotypes in a series of patients with Opitz GBBB syndrome with MID1 mutations https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:574 Thu 25 Jul 2013 09:10:29 AEST ]]> A method for meta-analysis of molecular association studies https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:577 Thu 25 Jul 2013 09:10:28 AEST ]]> Hereditary haemochromatosis: to screen or not to screen?

To establish if they are associated with an increased malignant melanoma (MM) risk we did an association study based on genotyping 471 patients with MM and 1,2 10 random control subjects from the same Polish population. We found a significantly increased frequency of the A148T variant among patients with MM (7.0%) in comparison with the general population (2.9%). The incidence of the A148T variant remained greater in both unselected and familial melanoma subgroups. A statistically significant positive association was seen for unselected MM (odds ratio, 2.529; P = 0.0003), especially in patients diagnosed under 50 years of age (odds ratio, 3.4; P = 0.0002). The A148T carrier population (heterozygous G/A alleles) was more likely to have a relative with malignancy compared with the noncarrier population (57% versus 36%, respectively; P = 0.03). Further examination of the CDKN2A promoter sequence done in 20 melanoma patients with the A148T change (heterozygous G/A alleles) and 20 patients with MM without this alteration identified it was in linkage disequilibrium with a polymorphism in the promoter region at position P-493. We found no statistically significant overrepresentation of the Nt500c>g and the Nt540c>t polymorphisms in the Polish melanoma population. In conclusion, the A148T variant of the CDKN2A gene seems to be associated with an increased risk of development of MM. Additional studies are required to confirm whether this particular change is associated with increased risk of other nonmelanoma malignancies.]]> Thu 25 Jul 2013 09:09:40 AEST ]]> SIAH1 targets the alternative splicing factor T-STAR for degradation by the proteasome https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:6573 Sat 24 Mar 2018 07:49:17 AEDT ]]> Small molecular weight variants of p53 are expressed in human melanoma cells and are induced by the DNA-damaging agent cisplatin https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:5341 Sat 24 Mar 2018 07:45:56 AEDT ]]> Investigation of Nicotiana tabacum (plus) N suaveolens cybrids with carpelloid stamens https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:142 Sat 24 Mar 2018 07:42:55 AEDT ]]> Gene expression imputation across multiple brain regions provides insights into schizophrenia risk https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47780 Mon 30 Jan 2023 10:58:57 AEDT ]]> Hemochromatosis mutations, brain iron imaging, and dementia in the UK Biobank cohort https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39219 HFE p.C282Y variant can cause iron overload and hemochromatosis, mostly in homozygous males. Objective: To estimate p.C282Y associations with brain MRI features plus incident dementia diagnoses during follow-up in a large community cohort. Methods: UK Biobank participants with follow-up hospitalization records (mean 10.5 years). MRI in 206 p.C282Y homozygotes versus 23,349 without variants, including T2* measures (lower values indicating more iron). Results: European ancestry participants included 2,890 p.C282Y homozygotes. Male p.C282Y homozygotes had lower T2* measures in areas including the putamen, thalamus, and hippocampus, compared to no HFE mutations. Incident dementia was more common in p.C282Y homozygous men (Hazard Ratio HR = 1.83; 95% CI 1.23 to 2.72, p = 0.003), as was delirium. There were no associations in homozygote women or in heterozygotes. Conclusion: Studies are needed of whether early iron reduction prevents or slows related brain pathologies in male HFE p.C282Y homozygotes.]]> Fri 27 May 2022 11:37:31 AEST ]]>
