FN1 and neoplasm: In OSCC, the ability of ZEB1-AS1 to bind miR-23a underlines its prooncogenic activity (Wang et al., 2021b), with PSMA3-AS1 sequestering miR-136-5p, and thus promotes the upregulation of the downstream target gene FN1, with the lncRNA thus contributing to more invasive tumor cell growth through the miR-136-5p/FN1 axis (Cao et al., 2021).
