The results were replicated in an independent cohort, the Hunter Community Study (p < 0.002) (n = 313). Conditional and joint analysis (COJO) confirmed the association of the chromosomal 17 region with ApoH levels. The set of independent SNPs identified by COJO explained 23% of the variance. The relationships between the top SNPs and cardiovascular/lipid/cognition measures and diabetes were assessed in Sydney MAS, with suggestive results observed for diabetes and cognitive performance. However, replication of these results in the smaller OATS cohort was not found. This work provides impetus for future research to better understand the contribution of genetics to ApoH levels and its possible impacts on health.]]> Wed 15 Dec 2021 16:09:56 AEDT ]]> Plasma apolipoproteins and physical and cognitive health in very old individuals https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34724 Thu 17 Feb 2022 09:27:08 AEDT ]]> APOE genotype differentially modulates plasma lipids in healthy older individuals, with relevance to brain health https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36726 ɛ4/ɛ3> ɛ3/ɛ3> ɛ2/ɛ3> ɛ2/ɛ2). The greatest variation in lipids was related to the ɛ2 isoform, where various lysophosphatidylcholines and all phosphatidylethanolamine (PE) subclasses were elevated relative to ɛ3/ɛ3 and ɛ4 carriers. APOE ɛ4 carriers had reduced phosphatidylinositol relative to ɛ3/ɛ3 and ɛ2 carriers. Logistic regression revealed that ɛ2 carriers were at least 4 times higher odds of being in the highest tertile of PE lipid level relative to ɛ3/ɛ3. The elevation in PE and other phospholipids in ɛ2 carriers may indicate the protective effect of ɛ2 is linked to these phospholipids. Additionally, high baseline PE in cognitively normal participants predicted protection against cognitive decline six years later. Our data suggest substantial modulation of plasma lipids by APOE genotype and therefore indicates possible lipid targets and pathomechanisms involved in AD risk.]]> Thu 02 Jul 2020 09:10:42 AEST ]]> Plasma protein profiling of mild cognitive impairment and Alzheimer's disease across two independent cohorts https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28945 Sat 24 Mar 2018 07:31:25 AEDT ]]>
