Researchers from Tokyo Medical and Dental University Detail New Studies and Findings in the Area of Neuroscience (Next-generation sequencing-based small RNA profiling of cerebrospinal fluid exosomes)
By a News Reporter-Staff News Editor at Genomics & Genetics Weekly -- Current study results on Nervous System Research - Neuroscience have been published. According to news originating from value="LU/jp..tokyo" idsrc="xmltag.org">Tokyo, Japan, by NewsRx correspondents, research stated, "MicroRNAs (miRNAs), particularly those found in human body fluids, have been suggested as potential biomarkers. Among various body fluids, the cerebrospinal fluid (CSF) shows promise as a profiling target for diagnosis and monitoring of neurological diseases."
Our news journalists obtained a quote from the research from value="ACORN:3297817221" idsrc="xmltag.org">Tokyo Medical and Dental University, "However, relevant genome-scale studies are limited and no studies have profiled exosomal miRNAs in CSF. Therefore, we conducted a next-generation sequencing-based genome-wide survey of small RNAs in the exosomal and non-exosomal (supernatant) fractions of healthy human CSF as well as serum in each donor. We observed miRNA enrichment in the exosomal fractions relative to the supernatant fractions of both CSF and serum. We also observed substantial differences in exosomal miRNA profiles between CSF and serum. Half of the reported brain miRNAs were found in CSF exosomal fractions. In particular, miR-1911-5p, specifically expressed in brain tissue, was detected in CSF but not in serum, as confirmed by digital PCR in three additional donors. Our data suggest that the brain is a major source of CSF exosomal miRNAs."
According to the news editors, the research concluded: "Here we provide the important evidence that exosomal miRNAs in CSF may reflect brain pathophysiology."
