SLCO1B1 expression was related to differentiation in liver cancer (395000 (225000 to 567000), 175000 (4300 to 310000), 47000 (11000 to 83000), and 3500 (N/A) for normal tissue, and well, moderately, and poor differentiated tumor tissue respectively; P = 0.0004, Figure 2B) up to a −74 fold difference. Here, SLCO1B1 is linked to liver cancer.
