The authors also proved that in non-small-cell lung cancer (NSCLC), SNHG7 directly bound to miR-3127-5p, an inhibitor of cell proliferation, invasion, and drug resistance [44], and metformin could increase miR-3127-5p levels in paclitaxel-resistant cells by inhibiting SNHG7 expression. Here, SNHG7 is linked to non-small cell lung carcinoma.
