circRNA-disease information
Expression pattern:
UP
Associated gene: ASF1B, Cyclin D1, E-cad, Vimentin, Ki67
Associated microRNA: miR-122-5p
Biological function: CircCDK17 acts as an oncogenic regulator in cervical cancer; its silencing inhibits CC cell proliferation, cell cycle progression, migration, invasion, and xenograft tumor growth.
Molecular mechanism: circCDK17 functions as a ceRNA that sponges miR-122-5p to post-transcriptionally regulate ASF1B expression, thereby modulating Cyclin D1, E-cad, and Vimentin and promoting cervical cancer progression.
Biological pathway or process:

proliferation (promotes); cell cycle (promotes); migration (promotes); invasion (promotes); metastasis (promotes); ceRNA regulation (promotes); other pathway/process (promotes)

Detected method:
Q
M
Validation methods:

RNase R Treatment; RT-qPCR; Microarray; Clinical Sample Validation; RNA Pull-Down; Luciferase Reporter Assay; Transfection; MTT; EdU Staining; Cell Cycle Assay; Transwell Assay; Wound Healing Assay; Western Blot; IHC (Immunohistochemistry); In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

circCDK17 expression was associated with TNM grade, tumor size, lymph node metastasis, and HPV status; up-regulated circCDK17 may have potential value as a diagnostic marker in cervical cancer.

Description:

circCDK17 is up-regulated in cervical cancer tissues and cells and functions as an oncogenic circRNA. It promotes proliferation, cell cycle progression, migration, invasion, and tumor growth by acting as a ceRNA for miR-122-5p and increasing ASF1B expression. Its expression is associated with clinicopathologic features and may have diagnostic or therapeutic relevance in cervical cancer.

Confidence score:

0.8175
