Conclusion
The transcription factor CTCFL fosters cell proliferative, migratory, and invasive properties via activating DPPA2 in gastric cancer.
Methods
We predicted gastric cancer-related transcription factors and corresponding target mRNAs through bioinformatics. Levels of CTCFL and DPPA2 were assessed via qRT-PCR and western blot. In vitro experiments were utilized to assay the cell biological behaviors. CHIP was utilized for the assessment of the targeted relationship between CTCFL and DPPA2.
Objective
To explore the relationship between CTCFL and DPPA2 and validate the positive role of CTCFL/DPPA2 in cell malignant behaviors in gastric cancer.
Results
CTCFL and DPPA2 were both highly expressed in gastric cancer cells, and high CTCFLL and DPPA2 could promote cell malignant behaviors. CHIP validated that DPPA2 was a target of CTCFL. In addition, high DPPA2 rescued the repressive impact of CTCFL silencing on the cell proliferation, migration, and invasion in gastric cancer.
