circRNA-disease information
Expression pattern:
DN
Associated gene: Rb
Associated microRNA: miR-574-3p
Biological function: circRNA_100782 is downregulated in gastric cancer; upregulation of circRNA_100782 inhibits gastric cancer cell proliferation, migration and invasion, whereas downregulation promotes migration and invasion.
Molecular mechanism: circRNA_100782 acts as a ceRNA and molecular sponge for miR-574-3p to regulate the expression of the tumor suppressor gene Rb.
Biological pathway or process:

ceRNA regulation (other); proliferation (inhibits); migration (inhibits); invasion (inhibits); metastasis (inhibits)

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Luciferase Reporter Assay; Transfection; CCK8; Transwell Assay; Survival Analysis; Bioinformatics Analysis

Clinical significance:

low expression of circRNA_100782 was associated with poor prognosis of gastric cancer

Description:

circRNA_100782 is significantly downregulated in gastric cancer tissues and SGC-7901 cells. Functional assays indicate that restoring circRNA_100782 suppresses gastric cancer cell proliferation, migration and invasion, while knockdown has the opposite effect. Mechanistically, circRNA_100782 acts as a miR-574-3p sponge/ceRNA to modulate Rb expression, and low circRNA_100782 expression is associated with poor prognosis.

Confidence score:

0.6987

Other information
Title:

CircRNA_100782 promotes roliferation and metastasis of gastric cancer by downregulating tumor suppressor gene Rb by adsorbing miR-574-3p in a sponge form.
