FOXA1 and osteosarcoma: A study indicated that the level of SBF2-AS1 is remarkably elevated, and this molecule positively regulates forkhead box A1 (FOXA1) expression via sponging miR-30a and suppressing the expression of miR-30a in osteosarcoma cells, significantly affecting biological processes, such as cell multiplication, invasion, migration and apoptosis [44].
