ABCG2 and cancer: The key metabolic pathways such as Glutathione metabolism (“CP vs. Ctrl”: p = 0; “ICA vs. CP”: p = 1 × 10–4), Arginine and proline metabolism (“CP vs. Ctrl”: p = 0; “ICA vs. CP”: p = 1 × 10–4), ABC transporters (“CP vs. Ctrl”: p = 0; “ICA vs. CP”: p = 0.0021), and Choline metabolism in cancer (“CP vs. Ctrl”: p = 6 × 10–4; “ICA vs. CP”: p = 3 × 10–4) were also almost the top ranked pathways.
