circRNA-disease information
Expression pattern:
UP
Associated gene: ATG7, ULK1, AGO2
Associated microRNA: miR-1275
Biological function: Promotes autophagic flux and promotes proliferation, thereby promoting breast cancer progression in vitro and in vivo.
Molecular mechanism: Acts as a miRNA sponge for miR-1275 to upregulate ATG7 and ULK1, enhancing autophagic flux.
Biological pathway or process:

autophagy (promotes); proliferation (promotes); ceRNA regulation (promotes)

Detected method:
Q
H
S
Validation methods:

circRNA-seq; RT-qPCR; ISH (In Situ Hybridization); Clinical Sample Validation; Cohort Study; Survival Analysis; RIP (RNA Immunoprecipitation); RNA Pull-Down; Microarray; Luciferase Reporter Assay; Transfection; CCK8; Colony Formation Assay; Annexin V/PI Flow Cytometry; Transwell Assay; Western Blot; IF (Immunofluorescence); IHC (Immunohistochemistry); In Vivo Animal Model; ddPCR

Clinical significance:

Increased circCDYL in tumor tissues and serum is associated with higher tumor burden, shorter survival and poorer clinical response to therapy; high serum circCDYL predicts poorer overall survival in MBC.

Description:

circCDYL (hsa_circ_0008285) is up-regulated in breast cancer tissues and serum, and high expression is associated with worse patient outcomes. It promotes breast cancer progression by acting as a miR-1275 sponge to upregulate ATG7 and ULK1, enhancing autophagic flux and proliferation.

Confidence score:

0.8547
