UCA1/miRNA204-5p/cAMP responsive element binding protein-1 (CREB1) axis [17], UCA1/miRNA-143/Fos-like antigen 2 (FOSL2) axis [18], and UCA1/miRNA-196a-5p/CREB axis [19] were involved in enhancing the chemoresistance of colorectal, ovarian, and bladder cancers. The gene discussed is FOSL2; the disease is urinary bladder carcinoma.
