TCF7L1 and neoplasm: The tumor sizes in the mice inoculated with miR-329-3p-transfected MG-63 cells (68.4 ± 8.3 cells/mm3) or TCF7L1-siRNA-transfected MG-63 cells (46.5 ± 6.5 cells/mm3) were significantly smaller than those transfected with untreated (339.2 ± 31.7 cells/mm3) and NC-miRNA-transfected cells (266.3 ± 14.6 cells/mm3) (Fig. 8C).
