circRNA-disease information
Expression pattern:
UP
Associated gene: KPNA4
Associated microRNA: miR-548I
Biological function: Promotes NSCLC cell viability/proliferation, migration, invasion and angiogenesis; inhibits apoptosis; promotes tumor growth in vivo.
Molecular mechanism: Acts as a miRNA sponge (ceRNA) for miR-548I to regulate KPNA4 expression.
Biological pathway or process:

ceRNA regulation (promotes); proliferation (promotes); migration (promotes); invasion (promotes); angiogenesis (promotes); apoptosis (inhibits)

Detected method:
Q
Validation methods:

RT-qPCR; RNase R Treatment; Clinical Sample Validation; Transfection; CCK8; EdU Staining; Transwell Assay; Tube Formation Assay; Annexin V/PI Flow Cytometry; Western Blot; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); In Vivo Animal Model; IHC (Immunohistochemistry); Survival Analysis

Clinical significance:

NSCLC patients with high circ_0008003 expression had low survival rates in comparison with the patients with low circ_0008003 expression.

Description:

hsa_circ_0008003 is up-regulated in NSCLC tissues and cell lines and its high expression is associated with poorer overall survival. Functionally, it promotes NSCLC malignant phenotypes and tumor growth by acting as a ceRNA to sponge miR-548I, thereby increasing KPNA4 expression.

Confidence score:

0.8068
