Abstract
Background
Previous study has indicated association between REG1α and bladder cancer. The aim
of this study was to investigate the role of Regenerating gene I alpha (REG1α) in
bladder cancer.
Methods
The role of REG1α in bladder cancer cell proliferation, migration and VEGF-induced
angiogenesis was explored in vitro and in vivo. Immunohistochemistry (IHC) analysis was assessed to determine the expression of
REG1α in ten paired bladder cancer and adjacent non-cancerous tissues, and in 296
bladder cancer samples.
Results
Down-regulation of REG1α expression significantly reduced the proliferation, migration,
invasion and VEGF-induced angiogenesis in vitro and the growth of xenograft tumors in vivo. VEGF expression in bladder cancer is associated with REG1α expression and recurrence.
REG1α was overexpressed in bladder cancer tissues compared with adjacent normal samples.
Patients with elevated REG1α exhibited shorter recurrence times and poor survival.
Conclusion
Downregulation of REG1α expression can reduce tumor growth, migration, invasion and
angiogenesis. Our study demonstrates that REG1α can be used as a marker of recurrence
and prognosis in bladder cancer. Therefore, REG1α targeting in bladder cancer patients
represents a promising therapeutic strategy.
