In particular, FGD5-AS1 facilitated non-small cell lung carcinoma cell proliferation via suppressing miR-107 to upregulate FGFRL1 (43); FGD5-AS1 facilitated oral squamous cell carcinoma progression by sponging miR-520b and inducing the expression of USP21 (44). The gene discussed is USP21; the disease is non-small cell lung carcinoma.
