As shown in Figure 2A,B, compared with the weight of xenograft tumour in GFP ctrl group (P < .01), that in TLR4 group was increased approximately by 2.5‐fold; however, compared with the weight of xenograft tumour in RNAi ctrl group (P < .01), that in TLR4i group was decreased approximately by three‐fourths. Here, TLR4 is linked to neoplasm.
