Results of qRT-PCR partially demonstrated the bioinformatics results that the mRNA levels of CXCL10, CXCL9, CCL5, and CCR2 were remarkably elevated in tumor tissues collected from PTC patients coexistent with HT than those without HT (Fig. 5, P < 0.001), while the mRNA level of FCGR3A did not differ (P > 0.05). This evidence concerns the gene FCGR3A and hematocrit.
