Research of thyroid cancer, liver cancer, and lung cancer has been reported in Korea. However microRNA research of multiple myeloma has never been reported. Hence we intended to confirm whether microRNA can be utilized as a diagnostic marker to patients of multiple myeloma. We also intended to evaluate whether microRNA can be detected in paraffin-embedded tissue (FFPE). This research was conducted targeting 8 samples from patients of multiple myeloma who do not have any other diseases, and 2 control samples. From January 2010 to July 2012, we selected miR-15a, miR-16, miR-21, miR-181a and miR-221 as microRNA target genes. It was decided that for a sample to be significant, the results should show values more than 1.5 or less than -1.5. Our findings of fold change were highly significant in miR-15a with a value of 37.5% (3/8). From these studies, we learned that miR-15a is useful with westerners. miR-221, on the other hand, shows conflicts with westerners, so more research will be needed in this area. In addition, it was confirmed that microRNA can be detected in paraffin embedded tissue (FFPE).
