| Outline of Final Research Achievements |
We extracted a trace amount of RNA from anterior aqueous humor from patients with ophthalmopathy of just a few 100 μL and tried comprehensive RNA analysis using next generation sequencer etc. About 360 kinds of microRNAs were successfully detected from one clinical specimen, and about one third of them were commonly detected in eight cataract specimens. Of these, 75% of the top 40 in expression levels were consistent with other studies reported during the study period. As a study that tried comprehensive analysis individually without mixing samples, our microarray analysis reported at the beginning of the research period is the first time, and the analysis scale by the next generation sequencer is the largest. In addition, as a surrounding study, we have examined microRNA analysis method and pathology model evaluation method and obtained basic knowledge.
