circRNA-disease information
Expression pattern:
UP
Associated gene: -
Associated microRNA: -
Biological function: Potential biomarker candidate for aggressive TNBC; implicated in tumor proliferation and invasion-related programs via subtype-specific m6A regulation.
Molecular mechanism: Subtype-specific m6A hypermethylation; proposed to affect circRNA stability/translation and potentially ceRNA activity (not experimentally validated for this circRNA).
Biological pathway or process:

Wnt/beta-catenin (other); proliferation (other); invasion (other); ceRNA regulation (other)

Detected method:
M
Validation methods:

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

Clinical significance:

Excellent discriminatory power between TNBC and luminal tumors (AUC = 0.88); host gene ZBTB16 high expression associated with worse overall survival.

Description:

hsa_circRNA_404935 (circZBTB16) is identified as a TNBC-associated circRNA with increased m6A methylation and reported upregulation versus luminal tumors, showing strong diagnostic discrimination (AUC ~0.88). The study links it to Wnt/beta-catenin-related enrichment and suggests prognostic relevance through the host gene ZBTB16 being associated with worse OS in TNBC.

Confidence score:

0.6405
