circRNA-disease information
Expression pattern:
DN
Associated gene: -
Associated microRNA: miR-28
Biological function: Suppresses NSCLC cell proliferation and promotes apoptosis (tumor suppressor role).
Molecular mechanism: Acts as a miRNA sponge by directly interacting with oncogenic miR-28 and suppressing miR-28 effects on proliferation and apoptosis.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; Nuclear-Cytoplasmic Fractionation; RNA Pull-Down; Transfection; BrdU; Annexin V/PI Flow Cytometry; Clinical Sample Validation; Cohort Study; Survival Analysis; Bioinformatics Analysis

Clinical significance:

Low expression levels of circ-MYBL2 were closely correlated with the poor survival of NSCLC patients.

Description:

In NSCLC, circ-MYBL2 is downregulated and mainly localized in the cytoplasm. It directly binds (sponges) miR-28, thereby antagonizing miR-28’s pro-proliferative and anti-apoptotic effects, consistent with a tumor-suppressive role and association of low circ-MYBL2 with poorer survival.

Confidence score:

0.7513
