circRNA-disease information
Expression pattern:
UP
Associated gene: -
Associated microRNA: hsa-miR-5683, hsa-miR-4779, miR-5683
Biological function: promotes malignant progression/metastasis-associated phenotype; associated with proliferation and angiogenesis indicators via miR-5683 correlation
Molecular mechanism: predicted circRNA-miRNA interaction with hsa-miR-5683 (negative correlation in tissues); direct binding not experimentally validated
Biological pathway or process:

proliferation (other); angiogenesis (other); ceRNA regulation (other)

Detected method:
Q
S
Validation methods:

RNA-seq; RT-qPCR; RNase R Treatment; Back-Splice Junction PCR / divergent primers PCR; Clinical Sample Validation; In Vivo Animal Model; Survival Analysis; Bioinformatics Analysis

Clinical significance:

enriched in EBVaGC CSC-derived exosomes; higher in EBVaGC patients with metastasis; detectable in serum exosomes from xenografts; potential liquid biopsy marker

Description:

hsa-circRNF13 is enriched and up-regulated in EBVaGC CSC-derived exosomes and is higher in EBVaGC tissues from patients with metastasis. Its expression is negatively correlated with hsa-miR-5683 in EBVaGC tissues, supporting a potential circRNA/miRNA regulatory relationship, and it may have value as a circulating exosomal biomarker (xenograft serum exosomes).

Confidence score:

0.7113
