circRNA-disease information
Expression pattern:
DN
Associated gene: GPX4
Associated microRNA: miR-214-3p
Biological function: circ_0010074 acts as an anti-ferroptotic ceRNA in CVB3-infected OSCC cells; its overexpression preserves cell viability, attenuates CVB3 infection, and counteracts CVB3-induced ferroptosis by maintaining GPX4 expression.
Molecular mechanism: circ_0010074 functions as a molecular sponge for miR-214-3p, relieving miR-214-3p-mediated suppression of GPX4; CVB3 downregulates circ_0010074, thereby increasing miR-214-3p activity, reducing GPX4, and inducing ferroptosis.
Biological pathway or process:

ferroptosis (inhibits); ceRNA regulation (other); proliferation (promotes)

Detected method:
Q
M
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; Sanger Sequencing; RT-qPCR; FISH / smFISH; Luciferase Reporter Assay; Transfection; CCK8; Western Blot; IF (Immunofluorescence); In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

-

Description:

In OSCC models, CVB3 downregulates hsa_circ_0010074/circ_0010074, which releases miR-214-3p to suppress GPX4 and promote ferroptosis. circ_0010074 itself functions as a cytoplasmic miR-214-3p sponge and has an anti-ferroptotic, cell-preserving role by sustaining GPX4 expression.

Confidence score:

0.7435
