circPTK2 levels in tissue and blood were correlated with poor differentiation, N2-N3 lymph node metastasis, and T(II-III-IV) stage; circPTK2 may be a potential biomarker and therapeutic target for bladder cancer diagnosis and therapy.
hsa_circ_0003221 (circPTK2) is up-regulated in bladder cancer tissues, patient blood, migrated cancer cells, and metastatic lymph nodes. Functional overexpression and knockdown experiments indicate that circPTK2 promotes bladder cancer cell proliferation, migration, invasion, and metastasis, and it may serve as a biomarker or therapeutic target, although the specific molecular mechanism was not defined.
