TGFB1 and neoplasm: Considering the potent immunoregulatory properties of prostaglandins (PTGS2) and TGFbeta (TGFB1), we evaluate the expression of PMEPA1, TGFB1, and PTGS2 in tumor cells, TAMs, CAFs, endothelial cells, T-cells, muscle cells, and urothelial cells via single-cell mRNA sequencing data acquired from GSE145137 (48).
