Then, we found that miR‐143‐3p is a shared miRNA between lncRNAs and mRNAs, including MAGI2‐AS3‐miR‐143‐3p‐COL1A1, NR2F1‐AS1‐miR‐143‐3pCOL1A1, and RP11‐999E24.3‐miR‐143‐3p‐COL1A1, and speculated that miR‐143‐3p and COL1A1 may be key genes involved in ceRNA pathways for gastric cancer (Figure 8). This evidence concerns the gene COL1A1 and gastric cancer.
