Relative expression of AXL and its ligand PROS1 in different cell lines. RNA was extracted from cultured Nthy, TPC1, and BCPAP cell lines separately. TPC1 and BCPAP are PTC cell lines that have been classified into the experimental group, while Nthy is the control group. The results indicate that PROS1 and AXL mRNA relative expression in TPC1 and BCPAP cell lines are overwhelmingly higher than that in the Nthy cell line (A, B). (**p < 0.01 compared to the control group)
