circRNA-disease information
Expression pattern:
UP
Associated gene: Wnt/beta-catenin pathway, beta-catenin, c-Myc
Associated microRNA: -
Biological function: promotes proliferation, stemness, EMT and migration of surrounding normal gastric epithelial cells (GES-1) and promotes gastric cancer development
Molecular mechanism: exosomal circ0000670 promotes gastric cancer development by regulating the Wnt/beta-catenin pathway and increasing beta-catenin and c-Myc expression
Biological pathway or process:

Wnt/beta-catenin (promotes); EMT (promotes); stemness (promotes); proliferation (promotes); migration (promotes)

Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; Back-Splice Junction PCR / divergent primers PCR; Sanger Sequencing; RNase R Treatment; Agarose Gel Electrophoresis; Clinical Sample Validation; Bioinformatics Analysis; Transfection; Western Blot; Transwell Assay; IF (Immunofluorescence)

Clinical significance:

circ0000670 was up-regulated in tissues of gastric cancer patients with smoking history

Description:

Exosomal circ0000670 is up-regulated in gastric cancer patients with smoking history and in cigarette smoke-exposed gastric cancer cells/exosomes. It promotes proliferation, stemness, EMT and migration in recipient GES-1 cells, at least partly through activation of the Wnt/beta-catenin pathway (beta-catenin and c-Myc).

Confidence score:

0.7571
