SLC7A11 and gastric cancer: For instance, CircRAB11FIP1 promotes ovarian cancer via miR‐129/DSC1 axis (Zhang, Zhu, & Hu, 2021), circEPSTI1 upregulates SLC7A11 expression in cervical cancer by miR‐375 (Wu et al., 2021) and circ_0110389 accelerates gastric cancer through miR‐127‐5p/SORT1 (Liang et al., 2021).
