circRNA-disease information
Expression pattern:
UP
Associated gene: AGO2
Associated microRNA: miR-451a, miR-148a-3p, miR-122-5p
Biological function: circ_0075320 is up-regulated in B[a]P-treated liver cancer cells and acts as a potential miRNA sponge associated with B[a]P-induced hepatocarcinogenesis and liver cancer metastasis.
Molecular mechanism: circ_0075320 functions as a potential cytoplasmic miRNA sponge and is enriched with AGO2, supporting involvement in a circRNA-miRNA regulatory mechanism.
Biological pathway or process:

ceRNA regulation (other); migration (other); metastasis (promotes)

Detected method:
Q
M
Validation methods:

RNase R Treatment; RT-qPCR; Microarray; FISH / smFISH; RIP (RNA Immunoprecipitation); Bioinformatics Analysis

Clinical significance:

circ_0075320 was identified as a B[a]P-upregulated circRNA and potential key RNA in liver cancer metastasis, but no direct diagnostic or prognostic clinical association for circ_0075320 expression was reported.

Description:

circ_0075320 is up-regulated in B[a]P-treated liver cancer cells and was validated as a circular, cytoplasmic RNA with AGO2 enrichment. The study proposes that circ_0075320 may act as a miRNA sponge and a key RNA associated with liver cancer metastasis, although a complete downstream mRNA axis was not experimentally established for this circRNA.

Confidence score:

0.5215
