circRNA-disease information
Expression pattern:
DN
Associated gene: BCL11B, P53
Associated microRNA: miR-330
Biological function: Suppresses proliferation, migration and invasion; induces G1 cell-cycle arrest and promotes apoptosis; inhibits tumor growth in vivo.
Molecular mechanism: Acts as a miRNA sponge for miR-330, releasing BCL11B expression and increasing P53 expression to trigger G1 arrest and apoptosis.
Biological pathway or process:

proliferation (inhibits); migration (inhibits); invasion (inhibits); cell cycle (inhibits); apoptosis (promotes); p53 signaling (promotes); ceRNA regulation (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; RNase R Treatment; Nuclear-Cytoplasmic Fractionation; Clinical Sample Validation; Transfection; CCK8; EdU Staining; Colony Formation Assay; Wound Healing Assay; Cell Cycle Assay; Annexin V/PI Flow Cytometry; Luciferase Reporter Assay; In Vivo Animal Model; H&E Staining; IHC (Immunohistochemistry)

Clinical significance:

circITGA7 was significantly downregulated in HCC tissue compared to adjacent non-tumor tissue and may be a potential biomarker; decreased circITGA7 levels were associated with a worse prognosis in HCC.

Description:

circITGA7 is down-regulated in HCC tissues and cell lines and functions as a tumor suppressor. It sponges miR-330, thereby de-repressing BCL11B and increasing P53 expression, which leads to G1 arrest and apoptosis and suppresses proliferation/migration/invasion and xenograft growth.

Confidence score:

0.7701
