Associated gene: -
Associated microRNA: -
Biological function: Potential contributor to aggressive TNBC phenotype (e.g., migration/tumorigenesis-related programs) as an m6A-altered circRNA candidate biomarker.
Molecular mechanism: Subtype-specific m6A hypermethylation; suggested to influence post-transcriptional regulation (stability/translation) (not directly validated).
Biological pathway or process:

migration (other); invasion (other); m6A modification (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_057041 (circMETTL8) is reported as a TNBC-associated circRNA with increased m6A methylation (and discussed as upregulated in TNBC). The study positions it as a candidate biomarker linked to aggressive TNBC-associated biological programs, though without circRNA-specific functional experiments.

Confidence score:

0.453
