In addition, Western blot results suggested that the expression levels of TNF‐α, TNFR1 and ASK1 in tumour tissues from the DC‐CIK‐OCSC group were significantly higher than those in other groups, whereas the expression level of phosphorylated ASK1 (p‐ASK1) was significantly lower than those in other groups (Figure 3). Here, TNFRSF1A is linked to neoplasm.
