SFRP2 and non-small cell lung carcinoma: By the same token, Wang Z et al. [23] showed that LINC00261 suppressed miR-105/FHL1 axis, Shi J et al. [24] demonstrated that the molecule sponged miR-522-3p leading to the overexpression of SFRP2 that inhibited Wnt signaling and Liao J et al. [47] showed that LINC00261 restrained the epithelial–mesenchymal transition (EMT) of NSCLC via downregulating Snail.
