circRNA-disease information
Expression pattern:
UP
Associated gene: -
Associated microRNA: hsa-miR-28-5p, ebv-miR-BART20-5p, ebv-miR-BART13-5p
Biological function: ebv-circRPMS1 likely serves as a miRNA sponge, downregulates human miRNA expression, promotes cell migration, and may regulate host and/or viral gene expression.
Molecular mechanism: Potential miRNA sponge mechanism; possible nuclear gene transcription regulation.
Biological pathway or process:

ceRNA regulation (promotes); migration (promotes); other pathway/process (other)

Detected method:
Q
H
S
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; Sanger Sequencing; RT-qPCR; RNA-seq; ISH (In Situ Hybridization); Nuclear-Cytoplasmic Fractionation; Clinical Sample Validation; Bioinformatics Analysis; Transfection; Wound Healing Assay; In Vivo Animal Model

Clinical significance:

ebv-circRPMS1 was detected in human EBVaGC tissue and NPC tissue, suggesting potential relevance to EBV-associated malignancies.

Description:

This study identified ebv-circRPMS1 as an EBV-encoded circular RNA derived from exons 2-4 of the RPMS1 gene and detected it in EBV-positive cell lines, xenografts, EBVaGC tissue, and NPC tissue. ebv-circRPMS1 localizes in both the cytoplasm and nucleus, may function as a miRNA sponge for human and EBV miRNAs, downregulates several human miRNAs upon overexpression, and promotes AGS cell migration in wound healing assays.

Confidence score:

0.7562
