circRNA-disease information
Expression pattern:
UP
Associated gene: PGK1
Associated microRNA: miR-335-5p
Biological function: Promotes BC cell viability, proliferation, invasion, tube angiogenesis, glycolysis and tumor growth, and inhibits apoptosis.
Molecular mechanism: circ_0022587 acts as a molecular sponge for miR-335-5p and positively regulates PGK1 expression through the miR-335-5p/PGK1 axis.
Biological pathway or process:

proliferation (promotes); invasion (promotes); angiogenesis (promotes); glycolysis (promotes); apoptosis (inhibits); ceRNA regulation (promotes); cell cycle (promotes)

Detected method:
Q
M
Validation methods:

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

Clinical significance:

High circ_0022587 expression was associated with poor prognosis of BC patients and low survival rate; the study suggests potential therapeutic relevance for BC.

Description:

circ_0022587 is upregulated in breast cancer tissues and cells, and high expression is associated with poor patient prognosis. Functionally, circ_0022587 promotes BC cell viability, proliferation, invasion, angiogenesis, glycolysis and in vivo tumor growth while suppressing apoptosis. Mechanistically, it acts through the circ_0022587/miR-335-5p/PGK1 regulatory axis.

Confidence score:

0.8202
