Background: CircPVT1’s effects and mechanisms of acute lymphoblastic leukemia were explored in this research.
Methods: Real-time fluorescent quantitative PCR was utilized to test circPVT1 and miR-125b in ALL samples and ALL cell systems. Dual luciferase reporter assay verified the combination of circPVT1 and miR-125b. We utilized circPVAT1 as well as miR-125b’s over-expression and low-expression to prove their influence on cell proliferation and invading.
Results: We found that more expression of circPVT1 occurred in ALL samples and ALL cell systems. CircPVT1 over-expression promoted ALL cell proliferation and migration besides invading. CircPVT1 low expression inhibited ALL cell proliferation and migration besides invading. MiR-125b was a target combination of circPVT1. CircPVT1 was able to enhance NF-κB signal pathway’s expression through reducing miR-125b.
Conclusions: CircPVT2 can promote ALL cell proliferation and invading through miR-125b modulation of NF-κB, which would be one new potential target for ALL therapy.
