| Outline of Final Research Achievements |
It has not yet been established a therapeutic strategy to reduce atherosclerotic lesions and plaques. We here tried to identify a novel long-noncoding RNA (lncRNA) associated with plaque formation and progression. We initially established an isolation methodology of monocytes from mice and handling of differentiated polarized macrophages. From these isolated primary cells, we prepared complementary DNAs and analyzed up- or down-regulated lncRNAs. We observed significant changes in expression for some lncRNAs upon polarization. We further invested whether oligonucleotide-based therapeutics can be a potential therapeutic strategy for manipulating lncRNA function. These findings would further enable us to develop a therapeutic strategy to treat atherosclerosis.
