circRNA-disease information
Expression pattern:
UP
Associated gene: HK2
Associated microRNA: miR-532-3p
Biological function: Promotes OSCC cell proliferation and glycolysis; tumour-promoting factor; circMDM2 knockdown represses tumour growth in vivo.
Molecular mechanism: circMDM2 acts as a miRNA sponge for miR-532-3p, thereby increasing HK2 expression (ceRNA axis circMDM2/miR-532-3p/HK2).
Biological pathway or process:

proliferation (promotes); glycolysis (promotes); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; Sanger Sequencing; Actinomycin D / DRB Stability Assay; RNase R Treatment; Nuclear-Cytoplasmic Fractionation; FISH / smFISH; Luciferase Reporter Assay; Transfection; CCK8; EdU Staining; Western Blot; In Vivo Animal Model; Survival Analysis; Bioinformatics Analysis; Clinical Sample Validation

Clinical significance:

circMDM2 was overexpressed in OSCC tissue and cells, and high expression served as a poor prognostic factor for OSCC patients.

Description:

circMDM2 is up-regulated in OSCC tissues and cell lines and promotes OSCC cell proliferation and glycolysis. It acts as a ceRNA by sponging miR-532-3p to upregulate HK2, and high circMDM2 expression is associated with poor patient survival.

Confidence score:

0.8419
