TYMS and cancer: Reports also indicate several other miRNAs, which in various types of cancer may regulate the level of protein encoded by TYMS and thus affect the sensitivity of cancer cells to 5FU chemotherapy, including miRNA such as miR-140-3p (Wan et al. 2021), miR-197-3p (Sun et al. 2015), miR-203a-3p (Li et al. 2015a), miR-218-5p (Li et al. 2015b), miR-330-3p (Xu et al. 2017), miR-375-3p (Xu et al. 2020b), miR-433-3p (Gotanda et al. 2013).
