FGD5 and oral cavity squamous cell carcinoma: 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).
