We used structural equation modeling to decompose the contributions of direct fetal and indirect maternal genetic effects, then applied Mendelian randomization to illuminate causal pathways. For example, both indirect maternal and direct fetal genetic effects drive the observational relationship between lower birth weight and higher later blood pressure: maternal blood pressure-raising alleles reduce offspring birth weight, but only direct fetal effects of these alleles, once inherited, increase later offspring blood pressure. Using maternal birth weight-lowering genotypes to proxy for an adverse intrauterine environment provided no evidence that it causally raises offspring blood pressure, indicating that the inverse birth weight-blood pressure association is attributable to genetic effects, and not to intrauterine programming.]]> Wed 22 Mar 2023 15:25:15 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29783 dif. In Escherichia coli, two tyrosine-family recombinases, XerC and XerD, bind to dif and carry out two pairs of sequential strand exchange reactions. However, what makes the reaction unique among site-specific recombination reactions is that the first step, XerD-mediated strand exchange, relies on interaction with the very C-terminus of the FtsK DNA translocase. FtsK is a powerful molecular motor that functions in cell division, co-ordinating division with clearing chromosomal DNA from the site of septation and also acts to position the dif sites for recombination. This is a model system for unlinking, separating and segregating large DNA molecules. Here we describe the molecular detail of the interaction between XerD and FtsK that leads to activation of recombination as deduced from a co-crystal structure, biochemical and in vivo experiments. FtsKγ interacts with the C-terminal domain of XerD, above a cleft where XerC is thought to bind. We present a model for activation of recombination based on structural data.]]> Wed 11 Apr 2018 17:12:14 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29042 Wed 11 Apr 2018 09:36:12 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49605 Tue 23 May 2023 16:01:03 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53505 Thu 30 Nov 2023 15:57:26 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:550 Thu 25 Jul 2013 09:10:25 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38986 Thu 24 Mar 2022 16:39:31 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46914 Thu 08 Dec 2022 08:47:20 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:11142 Sat 24 Mar 2018 08:10:28 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48483 LCT-13910 C/T, rs4988235) associated with dairy intake as an instrumental variable (IV). The causal effects of dairy intake on body composition and cardiometabolic traits (lipids, glycemic traits, and inflammatory factors) were quantified by IV estimators among 182041 participants from 18 studies. Results: Each 1 serving/day higher dairy intake was associated with higher lean mass [β (SE) = 0.117 kg (0.035); P = 0.001], higher hemoglobin A1c [0.009% (0.002); P < 0.001], lower LDL [-0.014 mmol/L (0.006); P = 0.013], total cholesterol (TC) [-0.012 mmol/L (0.005); P = 0.023], and non-HDL [-0.012 mmol/L (0.005); P = 0.028]. The LCT-13910 C/T CT + TT genotype was associated with 0.214 more dairy servings/day (SE = 0.047; P < 0.001), 0.284 cm higher waist circumference (SE = 0.118; P = 0.017), 0.112 kg higher lean mass (SE = 0.027; P = 3.8 x 10-5), 0.032 mmol/L lower LDL (SE = 0.009; P = 0.001), and 0.032 mmol/L lower TC (SE = 0.010; P = 0.001). Genetically higher dairy intake was associated with increased lean mass [0.523 kg per serving/day (0.170); P = 0.002] after correction for multiple testing (0.05/18). However, we find that genetically higher dairy intake was not associated with lipids and glycemic traits. Conclusions: The present study provides evidence to support a potential causal effect of higher dairy intake on increased lean mass among adults. Our findings suggest that the observational associations of dairy intake with lipids and glycemic traits may be the result of confounding.]]> Mon 20 Mar 2023 10:41:47 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42998 A and c.4534 C>T. Disease allele frequency was evaluated by genotyping of 1230 consecutive melanoma cases, 5000 breast cancer patients, 3500 prostate cancers and 9900 controls. Both variants were found to be absent among unselected cancer patients and healthy controls. The MutationTaster, Polyphen2 and SIFT algorithms indicate that c.9334G>A is a damaging variant. Due to lack of tumour tissue LOH analysis could not be performed for this variant. The variant segregated with the disease. The c.4534 C>T variant did not segregate with disease, there was no LOH of the variant. The c.9334G>A variant, classified as a rare variant of unknown significance, on current evidence may predisposes to cancers of the breast, prostate and melanoma. Functional studies to describe how the DNA change affects the protein function and a large multi-center study to evaluate its penetrance are required. © 2018 DeÎbniak et al.
