As shown in Fig. 1B and C, the expression of FATP2 is significantly up-regulated, and the expression of RIPK3 is significantly down-regulated in tumor tissues.The statistical analysis results indicate that the infiltration of PMN-MDSCs in bladder tumor tissue is positively correlated with the expression of FATP2 and negatively correlated with the expression of RIPK3 (Fig. 1D and E). Here, SLC27A2 is linked to urinary bladder neoplasm.
