circRNA-disease information
Expression pattern:
UP
Associated gene: ABCB1 mRNA
Associated microRNA: miR-34b-3p, miR-29c-3p, miR-877-3p
Biological function: contributes to docetaxel resistance; may act as a ceRNA/miRNA sponge leading to upregulation of ABCB1 expression
Molecular mechanism: ceRNA mechanism (miRNA sponge) affecting ABCB1 expression; pathway-level association with PI3K-Akt and AGE-RAGE signaling based on target enrichment of eligible miRNAs
Biological pathway or process:

ceRNA regulation (promotes); PI3K/AKT (other)

Detected method:
Q
S
Validation methods:

RNA-seq; Back-Splice Junction PCR / divergent primers PCR; RT-qPCR; Sanger Sequencing; Bioinformatics Analysis

Clinical significance:

-

Description:

circABCB1 is strongly up-regulated in docetaxel-resistant breast cancer cell lines. It is proposed to act as a ceRNA/miRNA sponge (e.g., miR-877-3p) and thereby promote ABCB1 expression, contributing to docetaxel resistance, with pathway associations inferred from enrichment (PI3K-Akt and AGE-RAGE).

Confidence score:

0.4761
