circRNA-disease information
Expression pattern:
UP
Associated gene: DNMT3A
Associated microRNA: miR-599
Biological function: Circ_0084615 promotes CRC cell proliferation, migration, invasion and metastatic potential; knockdown of circ_0084615 restrains these malignant phenotypes.
Molecular mechanism: Circ_0084615 functions as a competing endogenous RNA by sponging miR-599, thereby relieving miR-599-mediated repression of DNMT3A and increasing DNMT3A expression.
Biological pathway or process:

proliferation (promotes); migration (promotes); invasion (promotes); metastasis (promotes); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; Clinical Sample Validation; Nuclear-Cytoplasmic Fractionation; Bioinformatics Analysis; Luciferase Reporter Assay; Transfection; CCK8; Transwell Assay; Western Blot; In Vivo Animal Model; H&E Staining; Survival Analysis

Clinical significance:

Circ_0084615 up-regulation is associated with poor overall survival, higher TNM stage, and may be a prognostic biomarker and therapeutic target for CRC.

Description:

Circ_0084615 is an ASPH-derived human circRNA up-regulated in colorectal cancer tissues and cell lines. It promotes CRC proliferation, migration, invasion and lung metastatic colonization by acting as a ceRNA that sponges miR-599 and increases DNMT3A expression. Clinically, high circ_0084615 expression is associated with worse overall survival and higher TNM stage, suggesting biomarker and therapeutic-target potential.

Confidence score:

0.7486

Other information
Title:
