Because Lnc_AC006548.28 may participate in the regulation of LAMC2 by miR-223 competitively as a ceRNA (competitive endogenous RNA), we speculate that celecoxib may pass through Lnc_AC006548.28 which interacts with miR-223 to regulate the expression of LAMC2 and reverse the occurrence of gastric cancer. The gene discussed is LAMC2; the disease is gastric cancer.
