circRNA-disease information
Expression pattern:
UP
Associated gene: -
Associated microRNA: miR-936
Biological function: Associated with TNBC subtype; proposed to contribute to angiogenesis and invasive behavior, potentially via miRNA sponging.
Molecular mechanism: miRNA sponge (ceRNA) suggested; m6A hypermethylation suggested to enhance stability/translation (not directly validated).
Biological pathway or process:

VEGF/VEGFR (other); angiogenesis (other); ceRNA regulation (other); invasion (other)

Detected method:
M
Validation methods:

MeRIP / MeRIP-seq; Microarray; RNase R Treatment; Bioinformatics Analysis

Clinical significance:

Candidate subtype-specific m6A-modified circRNA biomarker for TNBC (differential methylation vs luminal).

Description:

hsa_circRNA_100719 (circDOCK1) is reported as hypermethylated and upregulated in TNBC relative to luminal subtypes. It is suggested to act as a miRNA sponge (miR-936) in angiogenesis-related contexts, linking it to VEGFA-VEGFR2 pathway regulation, but without direct functional validation in this study.

Confidence score:

0.453
