Effect of combination treatment with SOR and BA on the colony-forming ability of AsPC-1, BxPC-3, and Capan-1 cell lines. On the left: representative images of colonies formed by AsPC-1, BxPC-3, and Capan-1 cells after treatment with sorafenib (AsPC-1 and Capan-1: 5 µM, BxPC-3: 3 µM) and betulinic acid (6 µM) alone and in combination. On the right: the surviving fraction (SF) of AsPC-1, BxPC-3, and Capan-1 cells after treatment with sorafenib (AsPC-1 and Capan-1: 5 µM, BxPC-3: 3 µM) and betulinic acid (6 µM) alone and in combination (n = 3). * p < 0.05 ** p < 0.01 compared with the sorafenib treatment group and betulinic acid treatment group.
