“…MicroRNAs are small (20–26 nucleotides in length) noncoding RNAs, which have been shown to exist widely in plants and animals (Valencia‐Sanchez, Liu, Hannon, & Parker, ; John et al, ). MicroRNAs can participate in many important biological processes, including proliferation, migration, invasion, and angiogenesis (Ong, Lee, Kodo, & Wu, ; Ronald, ). To date, multiple studies have shown that miR‐210 can function as a tumor suppressor by inhibiting cell proliferation and promoting apoptosis, such as in ovarian cancer (Giannakakis et al, ) and in esophageal squamous cell carcinoma (Tsuchiya et al, ).…”
