In addition, the weight of the tumors in the SULF2 siRNA group (206.65±20.16 mg) was reduced compared to those in the control group (532.26±51.76 mg) (Figure 6A, P<0.05), while no obvious changes in tumor volume and weight were observed between the control and NC groups (all P>0.05). Here, SULF2 is linked to neoplasm.
