SULF1 and gastric cancer: Yoshifumi Takei et al14 demonstrated that the expression of miR‐516a‐3p in 44As3 cells (highly metastatic gastric cancer cells) was lower than that in HSC‐44PE cells (parental cells isolated from patients), and sulfatase 1 was a direct target of the miR‐516a‐3p in gastric cancer.
