CircGLIS3 functions as an oncogene via sponging multiple tumor-suppressive miRNAs in NSCLC. A circGLIS3/miR-644a/PTBP1 positive feedback loop exists in the tumorigenesis and development of NSCLC.
A circGLIS3/miR-644a/PTBP1 positive feedback loop promotes the malignant biological progressions of non-small cell lung cancer.
