Ren et al. (2019) found that knockdown of circDENND4C inhibited hypoxia-induced cell metastasis and glycolysis of breast cancer cells via upregulating miR-200b and miR-200c. Fang et al. (2020) reported that circSLAMF6 promoted GC cell migration and glycolysis under hypoxic stress through targeting the miR-204-5p/MYH9 axis. The recent circRNA heat-map analysis has indicated that circC6orf132 (hsa_circ_0092341) was highly expressed in GC tissue samples (Liu et al., 2019). Here, MYH9 is linked to gastric cancer.
