SLCO4A1-AS1 acts as a sponge for miR-508-3p and increases PARD3 expression and encourages colorectal cancer progression (13), whereas SLCO4A1-AS1 accelerates bladder cancer cell invasion by functioning as miR-335-5p ceRNA to promote OCT4 expression (11). This evidence concerns the gene SLCO4A1 and urinary bladder carcinoma.
