LncRNAs/circRNAs are targeted by miRNAs to reduce their stability and also function as molecular decoys or sponges of miRNAs.22 CircRNA Cdr1as is massively bound by miR‐7 and miR‐671 in human and mouse brain tissues.23 In osteoarthritis (OA), circRNA‐CER was reported to function as a sponge by competitively binding miR‐136 and could also target and regulate MMP13 via TGFβ, JNK and ERK pathways.24 Here, we found that miR‐195 levels were reduced in GC tissues when compared with their levels in adjacent non‐cancerous tissues and that miR‐195 could target hsa_circ_006100 in GC cells. The gene discussed is MMP13; the disease is gastric cancer.
