At the end of the experiment (the 22nd day), mice were euthanized and tumor tissues were excised, and the weight (Figure 7C) and size (Figure 7D) of xenografts formed by Caski/DDP cells with ANXA2P2 silencing were markedly inferior to those formed in the control group, while miR-361-3p knockdown exerted opposite effects; the effects of lncRNA ANXA2P2 knockdown were partially reversed by miR-361-3p inhibition. The gene discussed is ANXA2P2; the disease is neoplasm.
