FGF23 and neoplasm: However, the expression of FGF23 (log2 fold change; 0.031) and FGFR1 (log 2 fold change; 1.59) was not changed significantly by the transfection in addition to the KL/KLB, SPP1, SFRP4, and MEPE (Supplemental Data 1), even though the tumor mRNA showed relatively high FPKM in these genes (Supplemental Table 3).
