Exploration of potential circulating micro-RNA as biomarker for Alzheimer's disease
Alzheimer's disease (AD) is considered a progressive and devastating neurodegenerative disorder which primarily effects elders. Due to the course of the disease and the involvement of different gene loci with complex genetic studies, it is possible to calculate the relative risk of individuals at risk. In this study, our aim was to investigate the serum transcript levels of candidate microRNAs (miRNAs), including miR-138, miR-128, and miR-107 in patients with AD and compared with that of normal individuals. In this research work, during the diagnosis process of AD, 50 blood samples were obtained from patients and 50 samples were collected from healthy individuals. Then total RNA of each sample was extracted and the expression levels of miRNAs were measured by Real-time PCR method. Our analysis indicated that the relative expression of all three miRNAs decreased in AD patients compared to the healthy samples. There was statistically significant in transcript levels of miR-138 (P = 0.047) and miR-107 (P = 0.004), while the levels of miR-128 had no significant difference between two groups (P = 0.075). The receiver operating characteristic (ROC) curve analysis indicated the potential of all miRNAs as biomarkers in AD. In conclusion, miR-138 and miR-107 can be used as a diagnostic or predictive biomarker in AD. In the case of miR-128, more research is needed. We suggest further studies and evaluation of changes in the expression of these miRNAs in larger populations.

期刊介绍:
Meta Gene publishes meta-analysis, polymorphism and population study papers that are relevant to both human and non-human species. Examples include but are not limited to: (Relevant to human specimens): 1Meta-Analysis Papers - statistical reviews of the published literature of human genetic variation (typically linked to medical conditionals and/or congenital diseases) 2Genome Wide Association Studies (GWAS) - examination of large patient cohorts to identify common genetic factors that influence health and disease 3Human Genetics Papers - original studies describing new data on genetic variation in smaller patient populations 4Genetic Case Reports - short communications describing novel and in formative genetic mutations or chromosomal aberrations (e.g., probands) in very small demographic groups (e.g., family or unique ethnic group). (Relevant to non-human specimens): 1Small Genome Papers - Analysis of genetic variation in organelle genomes (e.g., mitochondrial DNA) 2Microbiota Papers - Analysis of microbiological variation through analysis of DNA sequencing in different biological environments 3Ecological Diversity Papers - Geographical distribution of genetic diversity of zoological or botanical species.
