XXYLT1 and cancer: Five—Using STRING database, we found that it had interactions with several proteins involved in different cancers such as TXNDC9 (Feng et al., 2020b), GXYLT2 (Cui et al., 2019), POFUT1 (Chabanais et al., 2018), XXYLT1(Zeng et al., 2021), FLNA (Guo et al., 2018), and ZC3H12C (Suk et al., 2018) (Figure 4).
