circRNA-disease information
Expression pattern:
UP
Associated gene: BDNF, TGFB1
Associated microRNA: miR-361-5p
Biological function: Key predicted ceRNA with strong potential for miRNA sponging, especially involving miR-361-5p, potentially enhancing downstream targets BDNF and TGFB1.
Molecular mechanism: Potential ceRNA mechanism through miR-361-5p sponging and downstream BDNF/TGFB1 regulation.
Biological pathway or process:

ceRNA regulation (promotes); MAPK (promotes); TGF-beta/SMAD (promotes); other pathway/process (promotes)

Detected method:
Q
S
Validation methods:

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

Clinical significance:

Linked through predicted downstream hub genes that may serve as potential prognostic biomarkers for HBV-HCC.

Description:

circPROX1 was included in the validated upregulated circRNA set and emerged as one of the key predicted ceRNA-network circRNAs. It was predicted to interact with miR-361-5p and to potentially enhance downstream targets such as BDNF and TGFB1 in HBV-HCC-related signaling.

Confidence score:

0.4761
