circRNA-disease information
Expression pattern:
DN
Associated gene: E2F7, SLC7A11, GPX4
Associated microRNA: miR-302a
Biological function: Inhibits DEX-induced ferroptotic cell death and oxidative stress in gastric cancer cells; promotes cell survival under DEX treatment.
Molecular mechanism: ceRNA mechanism: circ0008035 sponges miR-302a to positively regulate E2F7, thereby modulating ferroptosis-related markers (SLC7A11, GPX4) and ROS/iron/GSH balance.
Biological pathway or process:

ferroptosis (inhibits); oxidative phosphorylation (unclear); apoptosis (other); proliferation (inhibits); ceRNA regulation (other)

Detected method:
Q
Validation methods:

Microarray; Bioinformatics Analysis; RT-qPCR; Transfection; Luciferase Reporter Assay; CCK8; EdU Staining; Flow Cytometry(Non-apoptosis/cycle); Western Blot; In Vivo Animal Model; IHC (Immunohistochemistry); TUNEL

Clinical significance:

-

Description:

In gastric cancer cells, DEX decreases circ0008035, promoting ferroptosis. circ0008035 counteracts DEX-induced ferroptotic cell death by sponging miR-302a to maintain E2F7 expression, affecting ROS/iron/GSH and GPX4/SLC7A11 levels.

Confidence score:

0.6835
