Western blot and immunobiological staining indicate that treatment with Trp complex inhibited caprin1 and COX2 expression and adding antisense‐miR‐103‐3p or antisense‐miR‐107‐3p to Trp complex cancelled Trp complex‐mediated inhibitory effects on tumor cell metastasis to the liver (Figure 4J,K). The gene discussed is CAPRIN1; the disease is neoplasm.
