Ten days post-injection, the tumor volumes in mice treated with QER/LAC@GDEAP−TLs were approximately 3.8, 2.5, 3.9, 4.9, 4.6, and 4.9 times lower compared to mice treated with QER/LAC@GDOCA−TLs, the mixture containing QER@GDEAP−biotin−SLs and LAC@GDEAP−avidin−SLs, free QER/LAC mixture, free QER, free LAC, and saline, respectively. The gene discussed is LCT; the disease is neoplasm.
