circRNA-disease information
Expression pattern:
UP
Associated gene: HMGA2, Ras, ERK1/2, PCNA, HK2, OCT4
Associated microRNA: miR-217
Biological function: Promotes HCC cell proliferation/viability, glycolysis and stemness; promotes tumor growth; induces less apoptosis and less G2/M arrest (knockdown increases apoptosis and G2/M arrest).
Molecular mechanism: Acts as a miRNA sponge for miR-217 to upregulate HMGA2, affecting downstream proliferation/glycolysis/stemness markers (e.g., PCNA, HK2, OCT4; Ras/ERK).
Biological pathway or process:

glycolysis (promotes); stemness (promotes); proliferation (promotes); apoptosis (inhibits); cell cycle (other); ERK (promotes); ceRNA regulation (promotes)

Detected method:
Q
S
Validation methods:

RT-qPCR; RNase R Treatment; Clinical Sample Validation; Survival Analysis; Bioinformatics Analysis; Transfection; CCK8; EdU Staining; Cell Cycle Assay; Annexin V/PI Flow Cytometry; Colony Formation Assay; Western Blot; Luciferase Reporter Assay; RNA Pull-Down; In Vivo Animal Model; IHC (Immunohistochemistry); H&E Staining; RNA-seq

Clinical significance:

Upregulation of circBNC2 was related to poor prognosis and tumor node metastasis (TNM) stage.

Description:

circBNC2 is up-regulated in HCC tissues/cells and is associated with worse survival and more aggressive clinicopathological features. Functionally, circBNC2 promotes HCC proliferation, glycolysis and stemness and supports tumor growth in xenografts. Mechanistically, it acts as a ceRNA sponge for miR-217 to de-repress HMGA2, influencing downstream growth/glycolysis/stemness markers such as PCNA, HK2 and OCT4.

Confidence score:

0.8354

Other information
Title:

Circular RNA circBNC2 facilitates glycolysis and stemness of hepatocellular carcinoma through the miR-217/high mobility group AT-hook 2 (HMGA2) axis.
