Remarkably, the number of lung metastatic nodules from mice injected with LDLRAD2-overexpresion MGC-803 cell was more than that from control mice, while the number of lung metastatic nodules from mice injected with LDLRAD2-silenced BGC-823 cell was less than that from control mice, suggesting that LDLRAD2 could promote GC metastasis in vivo (Figure 3). The gene discussed is LDLRAD2; the disease is gastric cancer.
