CHST1 and cancer: This might include AZIN1 (antizyme inhibitor 1), SFRP1 (soluble frizzled related protein 1), or CHST1 (carbohydrate sulfotransferase 1) (Figure 10B) that were previously shown to be involved in cancer resistance to certain chemotherapeutic agents (e.g., paclitaxel, doxorubicin and cisplatin) [69,70,71,72] and targeted therapies [73,74,75,76] as well.
