Abstract
Circular RNAs (circRNAs) appear to be significant modulators in various physiological processes. Recently, it is found that circRNA_101996 exerts important roles in various cancers. Our previous studies showed that circRNA_101996 promoted cervical cancer growth and metastasis by regulating miR-8075/TPX2. However, the potential regulatory role of circRNA_101996 in cervical cancer still needs further investigation. Our results in this study suggested that circRNA_101996 was over-expressed in cervical cancer patients. circRNA_101996 up-regulation remarkably assisted cell proliferation, cell cycle progression, and cell migration in cervical cancer, while circRNA_101996 knockdown exerted the inverse effects. The molecular investigations indicated that circRNA_101996 could increase the expression level of miR-1236-3p, tripartite motif-containing 37 (TRIM37), through binding to miR-1236-3p and reducing its expression. Moreover, in vivo results demonstrated that circRNA_101996 shRNA can function as a tumor suppressor through down-regulating TRIM37 in cervical cancer. In conclusion, our data indicated that circRNA_101996/miR-1236-3p/TRIM37 axis accelerated cervical cancer development, providing novel insights into cervical cancer diagnosis and treatment.
