circRNA-disease information
Expression pattern:
UP
Associated gene: SIRT1, E-cadherin, Vimentin, p65, phosphorylated p65
Associated microRNA: miR-204, miR-204-5p
Biological function: Promotes GC cell proliferation, migration, invasion, metastasis, EMT, cell cycle changes and apoptosis; high expression is associated with tumor stage and poor prognosis.
Molecular mechanism: circNOP10 acts as a competing endogenous RNA sponge for miR-204, regulates SIRT1 expression, mediates EMT, and promotes GC progression through the NF-kappabeta pathway.
Biological pathway or process:

NF-kappaB (promotes); proliferation (promotes); migration (promotes); invasion (promotes); metastasis (promotes); EMT (promotes); apoptosis (promotes); cell cycle (other); ceRNA regulation (other)

Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; Back-Splice Junction PCR / divergent primers PCR; FISH / smFISH; RNA Pull-Down; Luciferase Reporter Assay; Transfection; Western Blot; CCK8; Transwell Assay; Cell Cycle Assay; Annexin V/PI Flow Cytometry; Clinical Sample Validation; Cohort Study; Survival Analysis; Bioinformatics Analysis

Clinical significance:

Increased circNOP10 in GC tissue was involved in tumor stage and prognosis; high circNOP10 expression was related to decreased overall survival and was an independent prognostic factor; it may serve as a prognostic biomarker and potential therapeutic target.

Description:

circNOP10/hsa_circ_0034351 is up-regulated in human gastric cancer tissues and peripheral blood cells, and high expression is associated with tumor stage, metastasis and poor overall survival. Mechanistically, circNOP10 acts as a miR-204 sponge to regulate SIRT1 and activate NF-kappabeta signaling, promoting malignant phenotypes including proliferation, migration, invasion and EMT.

Confidence score:

0.8423
