Identifying early-detection biomarkers have become an increasingly important approach in the treatment and prevention of Alzheimer's disease (AD). In this study, we investigated the potential of brain-derived neurotrophic factor (BDNF), complement factor H (CFH), tumor necrosis factor-α (TNFα), interleukin 10 (IL-10), and heat shock protein 90 (Hsp90) as(More)
Alzheimer's disease (EOAD, LOAD), mild cognitive impairment (MCI), Parkinson's disease (PD) and healthy controls were included to determine the serum interleukin-1s (IL-1α, IL-1β), IL-6 and alpha-2-macroglobulin (α2M) levels using ELISA. IL-6 might be a significant contributor to the inflammatory response in LOAD. The MCI data indicate that IL-1s, α2M and(More)
Vitamin D receptor (VDR) gene polymorphism has been reported to be a determinant of bone formation and intestinal calcium absorption. We carried out this study to assess the role of VDR gene polymorphism in the pathogenesis of osteomalacia. We investigated BsmI polymorphisms in the gene encoding the 1,25 dihydroxyvitamin D receptor in 38 patients with(More)
Scientists have worked for over a century to uncover the basis of Alzheimer's disease (AD) with the ultimate goal of discovering a treatment. However, none of the approaches utilized have defined the exact cause of the disease or an ultimate treatment for AD. In this review, we aim to define the role of vitamin D in AD from a novel and fundamental(More)
Vitamin D receptor (VDR) gene polymorphisms have been suggested as possible determinants of bone mineral density (BMD) and calcium metabolism. In this study, our aim was to determine whether there is an association between VDR gene polymorphism and osteomalacia or not. We determined ApaI and TaqI polymorphisms in the vitamin D receptor gene in 24 patients(More)
Vitamin D deficiency is suggested to be associated with Parkinson’s disease (PD). Our aim was to investigate the serum 25-hydroxyvitamin D3 (25OHD) levels of PD patients in Turkish cohort, to investigate any association of vitamin D binding protein (GC) genotypes with PD due to the significant role of GC in vitamin D transport, to determine whether vitamin(More)
Vitamin D is a secosteroid hormone that shares a synthetic pathway with cholesterol. ApoE, which is involved in the transport of cholesterol, is the most significant genetic risk factor for sporadic Alzheimer’s disease (AD). Surprisingly, recent studies have indicated the presence of an evolutionary juncture between these two molecules. To demonstrate this(More)
The challenge of understanding the biology of neuronal amyloid processing could provide a basis for understanding the amyloid pathology in Alzheimer's disease (AD). Based on our previous studies, we have suggested that AD might be the consequence of a hormonal imbalance in which the critical hormone is vitamin D. The present study primarily focused on the(More)
Tables 3, 4 and supplementary Table 4 of the original article contained errors in the labeling of the genotype and allele columns for the first GC SNP (rs2282679). The correct labels for the genotype columns (left to right) are ‘AA’, ‘CA’ and ‘CC’. The correct labels for the allele columns (left to right) are ‘A’ and ‘C’. The error did not affect the(More)
Intracellular aggregation of hyperphosphorylated tau in neurofibrillary tangles (NFTs) is a major neuropathological hallmark of taupathies such as Alzheimer's disease. Okadaic acid (OKA) is a potent inhibitor of PP2A, leading to abnormal tau phosphorylation. Brain-derived neurotrophic factor (BDNF) is a neurotrophin that is selectively downregulated in AD.(More)
