As shown in Figure 2b and 2c, the growth rate of xenograft tumors in mice implanted with 231-si-FOXD3-AS1 cells was significantly decreased following TMX treatment (scramble tumors compared with si-FOXD3-AS1 tumors: 600 vs. 220 mm3), whereas the opposite trend was revealed in mice injected with T47D-FOXD-AS1 cells (tumor sizes of empty vector vs. FOXD3-AS1 mice: 300 vs. 400 mm3). The gene discussed is FOXD3; the disease is neoplasm.
