circRNA-disease information
Expression pattern:
UP
Associated gene: VEGF
Associated microRNA: miR-29a
Biological function: Promotes HUVEC proliferation, migration/invasion and tube formation/angiogenesis; promotes GC cell migration; promotes tumor growth and angiogenesis in vivo.
Molecular mechanism: Exosome-delivered circ29 acts as a sponge of miR-29a and regulates VEGF expression/pathway in endothelial cells.
Biological pathway or process:

VEGF/VEGFR (promotes); angiogenesis (promotes); proliferation (promotes); migration (promotes); invasion (promotes); ceRNA regulation (promotes); other pathway/process (promotes)

Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; Clinical Sample Validation; Bioinformatics Analysis; Luciferase Reporter Assay; Transfection; EdU Staining; Transwell Assay; Tube Formation Assay; Western Blot; In Vivo Animal Model; IHC (Immunohistochemistry)

Clinical significance:

Potential therapeutic target and novel clinical marker for GC.

Description:

Exosomal circ29 is up-regulated in GC plasma and GC cells and is mainly carried in plasma exosomes. It promotes endothelial proliferation, migration/invasion, tube formation, angiogenesis and tumor growth by sponging miR-29a and increasing VEGF signaling/expression. The study suggests circ29 may be a therapeutic target and potential clinical marker for GC.

Confidence score:

0.7369
