circRNA-disease information
Expression pattern:
UP
Associated gene: YY1, PCNA, HK2, LDHA, ASCT2, GLS1
Associated microRNA: miR-330-5p
Biological function: promotes proliferation, glycolysis, and glutamine catabolism/decomposition of NSCLC cells; promotes xenografted tumor growth
Molecular mechanism: circ_0000517 sponges miR-330-5p to regulate YY1, affecting proliferation, glycolysis and glutamine decomposition in NSCLC
Biological pathway or process:

proliferation (promotes); glycolysis (promotes); glutaminolysis (promotes); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; Clinical Sample Validation; Survival Analysis; Luciferase Reporter Assay; RNA Pull-Down; Transfection; CCK8; Western Blot; In Vivo Animal Model; IHC (Immunohistochemistry); Bioinformatics Analysis

Clinical significance:

Overexpression of circ_0000517 was negatively correlated with the prognosis of NSCLC patients; associated with tumor size, lymph node metastasis, and tumor differentiation

Description:

circ_0000517 is up-regulated in NSCLC tissues and cell lines and its high expression is associated with worse overall survival. Functionally, circ_0000517 promotes NSCLC proliferation, glycolysis and glutamine catabolism and supports xenograft growth by acting as a ceRNA for miR-330-5p to increase YY1.

Confidence score:

0.7942

Other information
Title:

Silencing of circ_0000517 suppresses proliferation, glycolysis, and glutamine decomposition of non-small cell lung cancer by modulating miR-330-5p/YY1 signal pathway.
