PTH2 and neoplasm: An additional GSEA analysis also revealed that genes with expression levels correlated with MS3 were significantly enriched in tumor-stimulating regulatory T cell (Treg)-, T helper cell (Th) 2-, and Th17-specific genes (GSEA PTreg = 0.004, PTh2 = 0.004, and PTh17 = 0.008, Fig. 4e, Supplementary Fig. 9b) but not in Th1-specific genes (PTh1 = 0.43, Fig. 4e, Supplementary Fig. 9b)22,23.
