circRNA-disease information
Expression pattern:
UP
Associated gene: -
Associated microRNA: hsa-miR-7978, hsa-miR-6727-3p, let-7a-2-3p, hsa-miR-1202, let-7c-3p, hsa-miR-4793-5p, hsa-miR-4722-3p, hsa-miR-3194-5p, hsa-miR-3972, hsa-miR-4327, hsa-miR-4679
Biological function: May function as a competing endogenous RNA and play vital roles in BCa development; its expression in serum exosomes may have value for BCa prediction.
Molecular mechanism: Predicted ceRNA/miRNA sponge mechanism; overexpression of hsa-circRNA-0088088 reduced let-7a-2-3p levels, supporting the hsa-circRNA-0088088/let-7a-2-3p interaction.
Biological pathway or process:

ceRNA regulation (other); Wnt/beta-catenin (other); TGF-beta/SMAD (other); Hippo/YAP (other); other pathway/process (other)

Detected method:
Q
S
M
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; Sanger Sequencing; RT-qPCR; RNA-seq; Microarray; Clinical Sample Validation; Bioinformatics Analysis; Transfection

Clinical significance:

May serve as a stable exosomal biomarker for predicting BCa tumorigenesis, development and metastasis.

Description:

hsa-circRNA-0088088 is up-regulated in breast cancer serum exosomes and tissues. The study proposes that it may act as an exosomal ceRNA/miRNA sponge, especially through the hsa-circRNA-0088088/let-7a-2-3p interaction, and may have biomarker value for BCa prediction.

Confidence score:

0.695
