| Research Abstract |
The relative expression level of trefoil factor 3 (TFF3) mRNA to galectin-3 (LGALS3) mRNA (T/G ratio) is a useful marker to distinguish thyroid follicular carcinomas from adenomas. However, because of the interference by the simultaneously aspirated peripheral blood cells or infiltrating lymphocytes, the precise measurement of the T/G ratio in aspirates is difficult. We tested two methods of selecting thyroid tumor cells and removing blood cells from the aspirates. One method was selection with magnetic beads coated with Ber-EP4 antibody and the other was filtration through a nylon mesh. After selection with Ber-EP4 antibody, T/G ratios in aspirates showed varied degrees of difference from those in the corresponding tissues. After mesh filtration, differences in T/G ratios between the aspirates and the corresponding tissues were less than 200% in all eight cases. Mesh filtration of aspirates proved superior results for the measurement of T/G ratio.
