circRNA-disease information
Expression pattern:
UP
Associated gene: LINC00632
Associated microRNA: miRNA-7
Biological function: Associated with clinical response/resistance to anti-PD-1 immune checkpoint blockade (nivolumab); proposed biomarker of response.
Molecular mechanism: Putative ceRNA/miRNA sponge mechanism (sponging miRNA-7) in the context of ICB response.
Biological pathway or process:

ceRNA regulation (other); immune regulation (other)

Detected method:
Q
S
Validation methods:

RNA-seq; RT-qPCR; Clinical Sample Validation; Bioinformatics Analysis

Clinical significance:

Potential biomarker of response to nivolumab in metastatic cutaneous melanoma.

Description:

CDR1-AS (hsa-CDR1_0001) is differentially expressed between nivolumab responders and non-responders in cutaneous metastatic melanoma and is highlighted as a potential biomarker of ICB response. The study supports a putative ceRNA role for this circRNA, consistent with miRNA sponge activity (including miRNA-7, per prior knowledge), within immune-response regulatory networks.

Confidence score:

0.4032
