circRNA-disease information
Expression pattern:
UP
Associated gene: eIF4A3, Cyclin D1, Cyclin E1, CDK4
Associated microRNA: -
Biological function: Promotes proliferation and migration; promotes cell cycle progression (G0/G1 to S); no significant effect on apoptosis.
Molecular mechanism: circ_0007766 binds the RBP eIF4A3 and thereby up-regulates cell-cycle genes/proteins Cyclin D1, Cyclin E1 and CDK4.
Biological pathway or process:

proliferation (promotes); migration (promotes); cell cycle (promotes); apoptosis (other)

Detected method:
Q
M
Validation methods:

RT-qPCR; Microarray; Clinical Sample Validation; Transfection; CCK8; Wound Healing Assay; Cell Cycle Assay; Annexin V/PI Flow Cytometry; RIP (RNA Immunoprecipitation); Western Blot; Bioinformatics Analysis

Clinical significance:

circ_0007766 was significantly positively correlated with TNM stage and prognosis in lung adenocarcinoma patients.

Description:

circ_0007766 is up-regulated in lung adenocarcinoma tissues and cell lines. Its knockdown suppresses proliferation and migration and induces G0/G1 arrest. Mechanistically, it binds the RBP eIF4A3 and is associated with increased Cyclin D1/Cyclin E1/CDK4 expression to promote cell-cycle progression.

Confidence score:

0.6829
