LRG1 and urinary bladder carcinoma: As a ceRNA, PART1 can promote invasion, migration, and proliferation by targeting miR-4516 in breast cancer cells [39], regulate LRG1 expression in colorectal cancer by sponging miR-150-5p [40], enhance tumorigenesis by regulating the miR-503-5p/ FOXK1 axis in ovarian cancer [41], and promote proliferation while inhibiting apoptosis in bladder cancer, among others.
