The Effect of Sialic Acid on MiR-320a and Let-7e Expression in Human Glial Cell Line.
Introduction: Sialic acid is pivotal in various critical physiological events at molecular and cellular levels and pathological processes. Changes in sialic acid concentration are observed in many pathological processes; for example, some available data exist on the evaluated level of sialic acid and neurodegenerative prevalence. Presumably, sialic acid can play a significant role in regulating a diverse range of uncovered neurodegeneration factors and downstream targets. matrix metalloproteinases 9 (MMP9) is one factor that changes the exposure of different concentrations of sialic acid solution. Hence, we aimed to examine the possible effect of sialic acid solution exposure on the glial cell line in the expression patterns of miR-320a and let-7e as two upstream factors.
Methods: Human glial cell line was prepared from the Pasteur Institute of Iran and cultured in a dulbecco's modified eagle medium (DMEM) with 10% fetal bovine serum (FBS). The IC50 value of sialic acid was obtained by colorimetric assay for assessing cell metabolic activity 3-(4,5-Dimethylthiazol-2-yl (MTT), and the glial cell line was treated with sialic acid in 300, 500, 1000 μg/mL for 24 h to investigate the effect of the sialic acid ligand on the expression pattern of the miR-320a and let-7e. Total RNA was isolated from approximately 10×106 glial cells and was used from each sample for complementary dna (cDNA) synthesis. For quantitative analysis of miR-320a and let-7e, we used real-time polymerase chain reaction (PCR), and for statistical analysis, the SPSS v. 21 software was applied.
Results: Analyzing the real-time data revealed that the expression of miR-320a and let-7e was significantly increased (P<0.0001) in 300, 500, and 1000 μg/mL treated glial cells by sialic acid compared to the control group.
Conclusion: A possible linkage of sialic acid on miR-320a and let-7e regulation was observed in the glial cell line as proinflammatory factors in the inflammation pathway.
Highlights: Differing in sialic acid concentration is seen in various pathological states.MicroRNAs play a role in numerous biological processes and human disorders.miR-320a and let-7e expression levels displayed a significant increase in different sialic acid concentrations.
Plain language summary: Inflammation in the nervous system occurs because of numerous factors. Sialic acid is an inflammatory factor that promotes cellular inflammation, particularly in the glial cells. That is why it could serve as a useful model for simulating several neurodegenerative diseases, including Parkinson's and Multiple sclerosis. Changes in sialic acid concentration are observed in many pathological states, which could be a useful marker for identifying the inflammatory process. The present study was carried out to examine the impact of different concentrations of sialic acid on two non-coding RNAs in glial cells. Our research shows that these two microRNAs greatly increased when responding to sialic acid. We suggest that these two microRNAs are contributed to the neuroinflammatory pathways related to sialic acid.
期刊介绍：
BCN is an international multidisciplinary journal that publishes editorials, original full-length research articles, short communications, reviews, methodological papers, commentaries, perspectives and “news and reports” in the broad fields of developmental, molecular, cellular, system, computational, behavioral, cognitive, and clinical neuroscience. No area in the neural related sciences is excluded from consideration, although priority is given to studies that provide applied insights into the functioning of the nervous system. BCN aims to advance our understanding of organization and function of the nervous system in health and disease, thereby improving the diagnosis and treatment of neural-related disorders. Manuscripts submitted to BCN should describe novel results generated by experiments that were guided by clearly defined aims or hypotheses. BCN aims to provide serious ties in interdisciplinary communication, accessibility to a broad readership inside Iran and the region and also in all other international academic sites, effective peer review process, and independence from all possible non-scientific interests. BCN also tries to empower national, regional and international collaborative networks in the field of neuroscience in Iran, Middle East, Central Asia and North Africa and to be the voice of the Iranian and regional neuroscience community in the world of neuroscientists. In this way, the journal encourages submission of editorials, review papers, commentaries, methodological notes and perspectives that address this scope.
